The parameter calculation module 20 is used to generate a correction processing parameter
based on each lowest gain value and reference gain value acquired in the test. In one
embodiment of the present invention, the parameter calculation module 20 sets the gain value
having the smallest numerical value in each lowest gain value acquired in the test as the
reference gain value. For example, as shown in FIG. 5, the parameter calculation module 20 uses
10 dB as a reference gain value, since it is 10 dB (including when the frequency is 250 and 500
Hz) that the numerical values in the plurality of lowest gain values are minimum. In other words,
in the present embodiment, the reference gain value is dynamic and can be determined by
different test results, but the determination of the reference gain value of the present invention is
not limited to this, and the reference gain value is also unified. It is possible to default to a
specific gain value (eg, 20 dB).
[0031]
In the present embodiment, the parameter calculation module 20 respectively generates a
correction parameter by the difference between each acquired minimum gain value and the
reference gain value, and taking 4000 Hz as an example, when the acquired minimum gain value
is 70 dB, the parameter The calculation module 20 generates a correction parameter at 60 dB
which is the difference between the obtained minimum gain value and the reference gain value.
In the same way, other frequency correction parameters are also obtained in this manner, and
finally, a set of correction parameters at different frequencies is the above correction processing
parameters.

The parameter setting module 30 is used to generate a parameter setting command according to
the correction processing parameter, and the parameter setting command is used to adjust the
setting of gain values at different frequencies of the sound of the equalizer EQ. In one
embodiment of the present invention, when the lowest gain value of the acquired voice under the
specific frequency exceeds 10 × N dB than the reference gain value (0 <N <20, N is an integer
when performing a normal test) The parameter setting module 30 raises the gain value of the
sound of the equalizer EQ at the same frequency by N dB. For example, as in the above example,
11-04-2019
9
if the lowest gain value that the user can hear for the audio of frequency 4000 Hz temporarily
acquired is 70 dB, the difference with the reference gain value of 10 dB is 60 dB, and the
parameter setting module 30 at this time The sound of the equalizer EQ raises the gain value at a
frequency of 4000 Hz by 6 dB.
[0033]
After adjustment by the parameter setting module 30, the gain value in each mode of the
equalizer EQ is set in synchronization with the new gain value. Taking the above example as an
example, the gain value of the voice of frequency 4000 Hz in each mode is The setting of gain
values at other different frequencies is also adjusted by 6 dB higher than the original gain value
(FIG. 6, FIG. 7).
[0034]
FIG. 2 is a schematic view showing an implementation environment of the electronic device 90
according to the second embodiment of the present invention.

further includes an audio reproduction device 60 and a signal transmitter 94. The audio
reproduction device 60 includes a signal receiver 61, a second audio signal processing chip 62,
and a speaker 63. Signal transmitter 94 and signal receiver 61 link the signals in a wireless
communication manner. In the specific embodiment of the present invention, the sound
reproducing device 60 is a wireless earphone, but the present invention is not limited to this.
[0035]

equalizer adjustment system 1 by linking with the signal transmitter 94 by a signal, and can also
receive an audio signal (for example, music). In the specific embodiment of the present invention,
the signal receiver 61 and the signal transmitter 94 are both Bluetooth (registered trademark)
wireless communication modules. In other words, the audio reproduction device 60 is a wireless
communication system in the present embodiment. Although the signal link with the electronic
device 90 is performed, the present invention is not limited to this.

[0036]
The second audio signal processing chip 62 is electrically connected to the signal receiver 61
and the speaker 63, and includes an equalizer EQ. The parameter setting command from the
electronic device 90 causes the second audio signal processing chip 62 to set based on the gain
value after the equalizer EQ adjustment by adjusting the setting of the gain value at different
frequencies of the sound of the equalizer EQ, Thereafter, the input audio signal is processed to
generate an output audio signal, and the speaker 63 is used to emit a sound by the output audio
signal. In the specific embodiment of the present invention, the second audio signal processing
chip 62 is a microcontroller and the equalizer EQ is present in the microcontroller in the form of
software (firmware), but the present invention is not limited thereto. Absent.
[0037]
In the second embodiment, the functions of the equalizer adjustment system and the other
devices or elements not described in the electronic device 90 are the same as those of the first
embodiment, and thus the description thereof is omitted here.

As can be seen from the above description, the equalizer adjustment system 1 of the present
invention can provide an audiometric test process, and after the user has finished the
audiometric test, adjusts the equalizer EQ settings based on the audiometric test results. The
future sound emitted from the electronic device 90 or the audio reproduction device 60 can
satisfy the hearing condition of the user.
[0039]
Finally, referring to FIGS. 1 to 9 together, FIG. 9 is a step flow chart of the equalizer adjustment
method.
The steps shown in FIG. 9 will be sequentially described in combination with FIGS. 1 to 8 below.

the electronic device 90 shown in FIG. 1 or 2 as an example, but the equalizer adjustment
method of the present invention is limited to the method implemented in the electronic device

90. It is not something that can be done.
[0040]
First, step S1 of providing a hearing test process is performed.
[0041]
The equalizer adjustment method disclosed in the present invention can adjust the setting of the
gain value of the equalizer EQ according to the user's hearing situation.
Thus, to seek knowledge of the user's hearing situation, step 1 of the equalizer adjustment
method is to provide a hearing test process, and after the user has gone through the hearing test
process, the use of the speech of different frequencies. Get the lowest gain value that people can
hear.
[0042]
In one embodiment of the present invention, the step of providing the hearing test process in
step S1 comprises steps S101, S102, S103 and S104.
[0043]
Step S101 of providing a virtual button and displaying it on the screen is executed.
[0044]
For the hearing test process to perform, the button providing unit 11 of the test module 10
provides the virtual button 71 shown in FIG.
[0045]
Step S102 is performed to control the electronic device and emit a plurality of test voices of
different frequencies.
[0046]
After providing the virtual button 71, the voice generation unit 12 of the test module 10 then

controls the voice reproduction device 92 of the electronic device 90 or the voice reproduction
device 60 (Example 2 above) to perform a plurality of tests of different frequencies. Speak a voice
for
[0047]
The user executes step S103 of receiving a response command input when each test voice is
heard.
[0048]
Once the user hears the test voice, the virtual button 71 can be pressed to input a response
command, which is received by the response receiving unit 13 of the test module 10.
[0049]
Based on each response command, step S104 is executed to obtain the lowest gain value that can
be heard by the user for voices of different frequencies.
[0050]
After obtaining the lowest gain value of the voice heard by the user at different frequencies, the
recording unit 14 of the test module 10 then obtains the lowest gain value heard by the user for
each different frequency voice based on each response command. And can be recorded.
[0051]
After the hearing test process is completed, step S2 is then performed to generate correction
processing parameters based on the lowest gain value and the reference gain value.
[0052]
Once the lowest gain values that the user can hear for each different frequency of speech are
obtained through the execution of the hearing test process, then the parameter calculation
module 20 is based on each lowest gain value and reference gain value obtained in the test,
Corrective processing parameters can be generated.
In one embodiment of the present invention, the parameter calculation module 20 sets the gain
11-04-2019
13
value having the smallest numerical value in each lowest gain value acquired in the test as the
reference gain value.
For example, as shown in FIG. 6, the parameter calculation module 20 uses 10 dB as a reference
gain value, since it is 10 dB (including when the frequency is 250 and 500 Hz) that the numerical
values in the plurality of lowest gain values are minimum. In other words, in the present
embodiment, the reference gain value is dynamic and can be determined by different test results,
but the determination of the reference gain value of the present invention is not limited to this,
and the reference gain value is also unified. It is possible to default to a specific gain value (eg, 20
dB).
[0053]
In the present embodiment, the parameter calculation module 20 respectively generates a
correction parameter by the difference between each acquired minimum gain value and the
reference gain value, and taking 4000 Hz as an example, when the acquired minimum gain value
is 70 dB, the parameter The calculation module 20 generates a correction parameter at 60 dB
which is the difference between the obtained minimum gain value and the reference gain value.
In the same way, other frequency correction parameters are also obtained in this manner, and
finally, a set of correction parameters at different frequencies is the above correction processing
parameters.
[0054]
Finally, based on the correction processing parameter, step S3 of adjusting the setting of the gain
value at different frequencies of the voice of the equalizer is performed.
[0055]
Finally, after the correction processing parameter is generated, the parameter setting module 30
generates a parameter setting command according to the correction processing parameter, and
the parameter setting command can adjust the setting of the gain value at different frequencies
of the sound of the equalizer EQ, The sound output from the electronic device 90 in the future
can be adapted to the hearing condition of the subject, and the sound output can have an effect
of optimization for the user.
