DESCRIPTION JP2017512433
Abstract When the instruction is received from the user input, the name of the sound source
from the prioritized list of sound sources to which the headset is currently connected is output.
Whenever a continuous indication is received within a predetermined amount of time, the name
of the next wireless source in the list is output. The name of the sound source to which the
headset is currently connected, if the next wireless sound source in the list is the last wireless
sound source in the list and it receives a continuous indication from the user input before the
elapsed time exceeds the predetermined value Are output as the next selected wireless source in
the list. If an amount of time greater than a predetermined value has elapsed without a
continuous indication from the user input, the last wireless sound source that caused the name to
be output is connected.

2One device must first be paired in order to communicate via Bluetooth. 2The pairing sequence
between two Bluetooth devices typically requires user configuration operations on both devices
and the time for the Bluetooth devices to find each other. Once paired, devices can be connected
and disconnected under control of the device itself without having to repeat the pairing process.
Devices can be connected for various purposes, including remote control, exchange of data, or
playback on a speaker in another device of audio signals generated by one device. 1One host
device can be paired with multiple peripheral devices, but typically only one at a time is
connected to each of the one or more types of connections. In the context of this application,
when we refer to "Bluetooth", as of the filing date of this application Version 4.0 [Vol 0], June 30,
2010 Bluetooth specification released by Bluetooth Special Interest Group (Bluetooth SIG) It
refers to the protocols and connections that work with the. Other wireless technologies can
provide similar features and functions and can be used in the same manner.

The following presents a simplified summary in order to provide a basic understanding of some
aspects of the invention.
This summary is not intended to identify key or critical elements of the invention or to delineate
the scope of the invention. Its sole purpose is to present some concepts of the invention in a
simplified form as a prelude to the more detailed description that is presented later.
[0005]
In general, in one aspect, a wireless audio output device includes at least a processor, a memory,
a wireless interface, a user input, and a speaker. 2A list of one or more paired wireless sources is
stored in memory, the list including information about each wireless source, the information
including the name of each wireless source, and the list including at least a first wireless source
Including the last wireless source. An instruction is received from a user input. A speech
synthesis engine is used to generate an audio signal corresponding to the name of the selected
wireless source in the list. The speaker is used to output an audio signal. If an amount of time
11-04-2019

greater than the predetermined value has elapsed without receiving a continuous indication from
the user input, the output device connects to the selected wireless source.
[0006]
Implementations can include one or more of the following in any combination. The speech
synthesis engine generates the next audio signal corresponding to the name of the next selected
wireless source in the list whenever a continuous indication is received from the user input
before the elapsed time exceeds the predetermined value. The speaker is used to output the next
audio signal. If the amount of time greater than the predetermined value has elapsed without
continuous indication from the user input, the next selected wireless source is connected. If the
next selected wireless source in the list is the last wireless source in the list and if the elapsed
time receives a continuous indication from the user input before the predetermined value is
exceeded, then the first wireless source in the list Is used as the next selected wireless source in
the list.
[0007]
The first and second wireless sound sources from the list can both be connected to the wireless
output device, the first connected sound source being the main sound source and the second
connected sound source being the auxiliary sound source is there. The speech synthesis engine
generates the next audio signal corresponding to the name of the next selected wireless source in
the list whenever a continuous indication is received from the user input before the elapsed time
exceeds the predetermined value. And the speaker is used to output the next audio signal, and
when the amount of time greater than the predetermined value has elapsed without continuous
indication from the user input, the wireless output device is selected for the next Connected to a
wireless source. If the next selected wireless source is also the second connected source, the
second connected source is reassigned as the primary source, the first connected source is
reassigned as the secondary source, and If the selected wireless sound source of is other than the
first or second connected sound source, the next selected wireless sound source is assigned as
the main sound source and the first connected sound source is reassigned as the auxiliary sound
source Ru. The speech synthesis engine can be used to generate a confirmation audio signal
corresponding to the names of the main and auxiliary sound sources, and the speaker can be
used to output a confirmation audio signal.

The wireless interface may include a Bluetooth wireless interface, and the list of wireless sound
sources may include a list of Bluetooth sound sources paired with the wireless audio output
device. The elapsed time can be measured from the receipt of an instruction from the user
interface. The elapsed time can be measured from the step of outputting an audio signal that
identifies the current or next sound source. The user input may include momentary actuation of
the switch having an instantaneous actuation state. If the switch receives an indication that it is
held momentarily active for a predetermined period of time, the wireless interface detects
additional wireless sources, pairs with additional wireless sources, and lists additional wireless
sources. It can be operated to add. If the connection to the selected wireless source fails and an
error message is received from the selected wireless source, the wireless device can re-pair with
the selected wireless source. The user input may include an output from the electronic user
interface, the output corresponding to the indication of the next sound source in the electronic
user interface. Using the speech synthesis engine may include accessing the speech synthesis
engine through a wireless connection with one of the paired wireless sources. The switch may
include a three-point slide switch having a first, second and third position, the switch remaining
there when set to the first or second position, and the third position When it is set and released,
it returns to the second position, and the instantaneous operating state includes the step of being
set to the third position.
[0009]
In general, in one aspect, a set of headphones includes a processor, a memory, a Bluetooth
wireless interface, a switch with instant activation, and a pair of speakers. The memory contains
an ordered list of Bluetooth enabled sound sources that were previously paired with the wireless
audio output device, the list contains information about each sound source, the information
including the name of each sound source, at least a first sound source and the last Including
sound source. The processor is configured to perform a sound source selection process including
receiving an instruction from the user input and using a speaker to output the name of the sound
source in the list to which the headset is currently connected. Be done. Outputs the next audio
signal corresponding to the name of the next wireless source in the list whenever a continuous
indication is received from the user input before the amount of time greater than the
predetermined value passes after the outputting step Speakers are used. If the next wireless
sound source in the list is the last wireless sound source in the list and a continuous indication
from the user input is received after the step of outputting the next audio signal until the elapsed
time exceeds the predetermined value The name of the sound source to which the headset is
currently connected is output as the next selected wireless sound source in the list. If an amount
of time greater than a predetermined value has elapsed without a continuous indication from the

user input, the last wireless sound source that caused the name to be output is connected.
[0010]
These and other features and advantages will be apparent upon reading the following detailed
description and studying the associated drawings. It is to be understood that both the foregoing
general description and the following detailed description are by way of illustration only and not
as limitations on the claimed aspects.
[0011]
FIG. 1 is a block diagram of an exemplary wireless entertainment system. It is a flowchart. It is a
flowchart.
[0012]
As shown in FIG. 1, an exemplary wireless entertainment system 10 includes a wireless playback
device 15 and one or more wireless sound sources 20a, 20b and 20c. Example wireless playback
devices include, but are not limited to, headsets, portable speakers, car entertainment systems,
home theater systems, and the like. Examples of wireless sound sources 20a, 20b, 20c include,
but are not limited to, entertainment systems, communication systems, personal computers,
smart watches, and the like. In some instances, Bluetooth wireless technology is used to provide
wireless communication between system components.
[0013]
In some examples, the wireless playback device 15 includes a processor 25, a memory 30, a
wireless communication module 35, and a speaker 40. The wireless communication module may
include, for example, a Bluetooth wireless communication interface or other similar interface. The
wireless playback device 15 also includes a switch 50 linked to the processor 25. In one example,
switch 50 is a momentary switch. In another example, as shown in FIG. 1, the switch 50 is stable
when at least one of the positions is stable, ie, when the switch is set there, and at least one of the
positions is instantaneous That is, it is a multipoint switching slide switch such as a three-point
11-04-2019
5
selector switch which returns from the instantaneous position to the stable position when the
switch is released. In some instances, such a position has two stable positions corresponding to
the on and off states of the device and a third instantaneous position used as an instantaneous
switch 50, as described below. . In another example, the wireless playback device 15 includes an
electronic user interface (UI), in which case the switch 50 of FIG. 1 represents a particular signal
output from that UI to the processor 25.
[0014]
Processor 25 controls the general operation of the wireless playback device. In some instances
where Bluetooth or similar wireless technology is used, processor 25 initiates the Bluetoothspecific functions implemented in wireless module 35 upon detection of an event, as described
below. . Processor 25 uses Bluetooth wireless technology to perform the operations (eg, pairing)
necessary to establish communication between wireless playback device 15 and one or more
wireless sound sources 20a, 20b, 20c. Start.
[0015]
Memory 30 may include any suitable memory technology, such as read only memory (ROM),
random access memory (RAM), or flash ROM, to name a few. Among other things, the memory
may be microcode of a program for processing and controlling the processor 25, as well as
various reference data, data generated during execution of any of the various programs
implemented by the processor 25, and telephone Store various updatable data for storage of
books, sent messages, received messages, etc. Different types of data can be stored in different
types of memory. The memory includes executable code for the general operation of the wireless
playback device as well as the speech synthesis engine, and instructions for performing
processing for direct selection of sound sources. Due to the direct selection process of the sound
source and the switch 50, the processor 25 is paired with the wireless module 35 without
manual interaction with the sound source and through a simplified user interface (UI) as
described below It is possible to connect to the wireless sound source from the set of sound
sources.
[0016]
The wireless module 35 enables wireless connection using radio frequency (RF: Radio Frequency)
11-04-2019
6
communication between the wireless playback device 15 and the wireless sound sources 20a,
20b, 20c. The wireless module 35 exchanges wireless signals including data input / output
through an antenna (not shown). For example, when using Bluetooth wireless technology in
transmit mode, the wireless module 35 processes data by channel coding and spreading,
converts the processed data to a radio frequency (RF) signal, and transmits an RF signal. In the
receive mode, the wireless module 35 converts the received RF signal into a baseband signal,
processes the baseband signal by despreading and channel decoding, and recovers the processed
signal into data.
[0017]
Each of the wireless sound sources, for example, the sound source 20a, may include a processor,
a memory, and a wireless communication module implementing Bluetooth or other suitable
wireless technology. The particular structure and technology of the sound source device note
that the wireless communication module corresponds to the wireless module 35 of the wireless
playback device 15 to interact with the wireless playback device in the manner described below:
Not within the scope of the present disclosure. In some examples, a voice synthesis engine is
embedded in one of the connected wireless sources, available for use by a wireless playback
device, or the wireless playback device is also connected to a wide area network Provided by an
online service that can be connected through one of the wireless sources.
[0018]
As shown in FIG. 2, a process 200 is performed by the wireless playback device 15 to directly
select one of the sound sources. Process 200 begins with detecting (205) a wireless sound
source. The playback device then pairs 210 with each of the detected wireless sources, for
example by performing a Bluetooth pairing process of each source. The playback device then
stores a list of paired sound sources in memory (215), the list including information about each
paired sound source. The information includes the name of each of the paired sound sources. The
steps of detecting the sound source, pairing with the sound source, and storing the information
of the sound source can be performed at any time, and the list of sound sources, which increases
as needed, is used in a later step. The remaining steps are relevant when at least two sound
sources are paired and included in the list.
[0019]
11-04-2019

At step 220, the playback device receives an indication that the switch 50 has been actuated. In
response, the playback device looks up the name of the current sound source from the
information on the sound source in the list of sound sources or in a store of information on the
current sound source (225). The playback device then uses a speech synthesis engine resident in
memory to generate an audio signal enabling it to speak 230 the name of the current sound
source.
[0020]
Once the name is output, the playback device waits for a predetermined amount of time (235) to
see if switch 50 has been reactivated (240, ignoring optional step 265 discussed below). . In
some instances, time is measured from the end of the audio output. In another example, time is
measured from the last switch input. If the switch is not activated again within the predetermined
amount of time, the playback device connects 245 to the sound source associated with the name
just output. Only when the said sound source is the currently connected sound source, step 245
has the effect of maintaining the current state.
[0021]
If the continuous indication (240) from the switch is received within a predetermined amount of
time, the playback device provides the user with the next sound source in the list. The playback
device does this by first checking if the end of the list has been reached (250). If there are more
sources in the list, the playback device increments the provided source to the next source in the
list and resets the time to wait for another switch to activate (255). The playback device looks up
260 the name of the new source and returns to step 230 so that the playback device speaks the
audio signal corresponding to the name of the next source in the list. This process is repeated
until either the switch is not pressed and either the last told sound source is connected (245) or
the end of the list is reached (250).
[0022]
If the process reaches the end of the list of paired sound sources and the switch continues to
operate so that the switch is pressed again one more time, the playback device reverts to the
currently connected sound source and starts again anew (225).

[0023]
While the above example treats the switch 50 as an electronic switch that can be manually
actuated by the user, other methods of user input are suitable.
For example, an automatic voice response system may detect that the user says "next sound
source" and provide an electronic indication to process 200 as a "switch" input 220. In another
example, a motion sensor may detect that the user shook his hand in a particular manner and
interpret this as an indication of the "next sound source" provided to the process 200.
[0024]
In this way, a switch or equivalent input is used to select any of the sources from the list of
paired sources. Each time the switch is pressed, it proceeds to the next paired sound source in
the list and the device connects when it receives no further switch indication. In some instances,
switch 50 is used to provide additional user interface functionality. If the switch is held in its
instantaneous position rather than being pressed and released, the system treats it as a different
input. For example, as shown in optional step 265 of FIG. 2, holding the switch in an
instantaneous position longer than some preset limit indicates that the user wishes to connect to
a device not yet in the list be able to. The playback device responds by returning to step 205 to
detect new sound sources that did not exist when those steps were previously performed, pair
with the new sound source, and add it to the list . A test of whether the switch has been held
longer than the limit may be performed each time the switch is pressed, ie, as shown by the
dashed line in the flow chart as well as before step 235, step 265 before step 225. Can be
inserted effectively. The limit on how long the switch will be held before resuming pairing should
be the same as or different from the time you have to press the switch after the last prompt to
cycle to the next source in the list Can.
[0025]
The steps of detecting and pairing sound sources can also be repeated in other situations. For
example, if the user unpaired the playback device from the sound source device through the user
interface of the sound source device, the playback device still provides the sound source device
when performing steps 255, 260 and 230, and connects with the sound source device Try.
However, in such situations, step 245 will fail and an error message (275) will be returned from
11-04-2019
9
the source device (unless the error will occur if the device is simply off or out of range) . Instead
of simply informing the user that the connection has failed, the playback device returns to step
205 and starts the pairing process again, so that the user can re-pair the playback device and the
sound source device.
[0026]
FIG. 3 shows another embodiment of the process of FIG. 2 in which the active connection is
maintained at two of the sound sources in the list. An optional step of testing whether the switch
is held longer than the limit and resuming the pairing process is not shown, but can be used for
this process as well as process 200. The first and subsequent switch inputs are also not shown,
but are assumed to trigger an action each time the switch is pressed. The process 300 begins
with the steps of detecting a sound source (205) and pairing with a sound source (210) as in
process 200 and storing a list of sound sources (215). The playback device then connects 305
two sources of sound, called the primary and secondary sources. In some instances, the two
sound sources are treated differently, eg, the user interface input can be directed to the main
sound source, while the audio is either mixed or according to the priority of the sound source
Depending on how you play from any sound source. The priority can be based on the designation
of "primary" or "secondary", or based on the type of sound source, for example, in an airplane
pilot headset, even if it is an auxiliary sound source for user input purposes, Airline always takes
precedence. In some cases, when audio reproduction is started from the sub sound source, the
main sound source and the sub sound source may be switched.
[0027]
When the switch is pressed for the first time (220), the playback device gets the names of both
the primary and secondary sources (325) and speaks them both (330). If the switch is repeated
within a pre-configured time limit (235), a potential new source is set to the next source in the
list after the main source (340). When the button is first pressed, there is always at least one next
sound source in the list, a secondary sound source. 1If only one sound source is present, the
system returns to process 200. In some instances, the secondary sound source is always the first
sound source provided when the user initiates this process. In another example, the order of the
devices in the list can be fixed, thus providing a secondary sound source when the order comes.
The playback device gets the name of the new source (345) and speaks it (350). If the switch is
pressed again within the pre-configured time limit (355), the device now tests whether it has
provided the last sound source in the list (360). If so, a new source is set as the main source
(365) and, as before, it returns to the beginning of the list.
11-04-2019
10
[0028]
When the user stops pressing the switch, the device assumes 370 that the new sound source is
other than the currently connected sound source and connects 370 to the new sound source. In
some instances, the playback device can be connected to only two sound source devices at a
time, and thus the previous secondary device can be omitted if it has not been selected as a new
main sound source. If the selected new source was previously the secondary source (375), then
the primary and secondary sources are swapped (380) and the previous primary is made the new
secondary, and vice versa. If the new sound source was not previously a secondary sound source,
then a new secondary sound source is set to the previous primary sound source (385). In some
instances, the secondary source can be used without being the primary source, so the last of the
previous primary and secondary sources used as the new secondary source (or secondary
source) The main sound source is set to a new sound source (390). This can be advantageous, in
which case the user is not actually expected to know the difference with the main or secondary
sound source, but only expect the last used sound source to remain connected. is there. The
trivial case that the new sound source is the existing main sound source is then unchanged and is
not illustrated. Alternatively, the step of selecting an existing main sound source can be used to
omit the connection to the auxiliary sound source, only leaving the main sound source connected.
After the primary and secondary sources have been updated (or possibly not), the device speaks
both names (395) to allow the user to confirm the outcome of the interaction.
[0029]
For both of the processes discussed above, the list of sound source devices has an order. In some
instances, the order is dynamically changed, so only the main device or connected devices are in
the first position in the list and the secondary device, if any, is the second position. Cycling
through the list starts from the second position, so the secondary device, if any, is presented first,
allowing the user to quickly turn it into the main sound source. In some instances, the list stored
in memory is not changed during operation, but the main device is presented between the last
and the first device when cycling through the list, and the secondary device follows process 300
When presented first, then the rest of the stored list is used in order. In another example,
according to the order of the list, the primary and secondary devices are simply presented in
order according to their order. The starting point may be the beginning of the list or the first
device after the current main device each time the process is started, ie the whole order is
maintained but the starting point is variable Do. In yet another example, only the secondary
device changes order so that the secondary device is always provided first, but the primary
11-04-2019
11
device is presented at any position it holds in the list. In some examples, the playback device
includes a power down process that stores the list updated by the last device that was the
primary and secondary sources moved to the first and second positions in the list, Enables fast
return to the current state when power is supplied by backup.
[0030]
The direct source selection process 200 is illustrated in the context of BLUETOOTH
SPECIFICATION Version 4.0 [Vol 0], June 30, 2010. However, it should be understood that the
above scheme is equally applicable to other wireless protocols. Furthermore, although certain
embodiments are described above as not requiring manual intervention to initiate the pairing
step, in some embodiments, manual intervention may be performed, for example, by the source
device being wireless If turned off, it may be necessary to complete the pairing step to provide
further security aspects to the scheme or manual selection. Although the above devices and
processes were in the context of sound source and audio playback devices, other devices using
similar wireless pairing lists can utilize the same process. For example, a tablet computer can be
paired with multiple wireless keyboards, named through each of the paired keyboards, and can
use a single "connected" user interface element to cycle .
[0031]
While the above describes a particular order of operations performed by one embodiment of the
present invention, alternative embodiments may perform the operations in a different order,
combine certain operations, duplicate certain operations, etc. As such, it is to be understood that
such an order is exemplary. Reference to a given embodiment herein may be such that the
described embodiment includes specific features, structures, or characteristics, but any
embodiment does not necessarily include the specific features, structures, or characteristics. It
indicates that it may not be included.
[0032]
Those skilled in the art will appreciate that although given components of the system have been
described separately, some of the functions may be combined or shared with a given instruction,
program sequence, portion of code or the like.
