The present invention relates to a magnetic levitation speaker, and more particularly to a
wirelessly chargeable magnetic levitation speaker.
[0002]
The conventional magnetically levitated speaker comprises a base including a lower magnetic
body and a body including an upper magnetic body.

[0004]
Prior art magnetic levitation speakers are charged by an external power supply.
Such maglev speakers are not convenient to use.
[0005]
Therefore, an object of the present invention is to provide a wirelessly chargeable magnetic
levitation speaker.
[0006]
In order to achieve the above object, the magnetic levitation speaker of the present invention
comprises a base and a body floating above the base.
The base has a shell, a wireless charging feed end housed in the shell, a controller and a lower
magnetic body. The main body includes a lid, an upper magnetic body housed in the lid, and a
wireless charging receiving end. The magnetism of the upper magnetic body is different from the
magnetism of the lower magnetic body.
[0007]
Compared to the prior art, the invention has the following advantages. The magnetically levitated
speaker has a wireless charging receiving end. When the wireless charging feed is energized, the
wireless charging feed charges towards the body. The magnetically levitated speaker is wirelessly
chargeable.

a disassembled perspective view of the main body of the magnetic levitation speaker shown in
FIG. It is a disassembled perspective view of the base of the magnetic levitation speaker shown in
FIG. It is a perspective view of the canopy part of the magnetic levitation speaker shown in FIG. It
is sectional drawing which cut | disconnected the magnetically levitated speaker shown in FIG. 1
along the AA.
[0009]
As shown in FIGS. 1 and 5, the magnetically levitated speaker 100 according to the present
invention comprises a base 2 mounted on an object such as a table, and a main body 1 floating
above the base 2. The base 2 has a plurality of supports 262 supported by the table.
[0010]
As shown in FIGS. 1 and 2, the main body 1 includes a lid 10 assembled by an upper lid 11 and a
lower lid 17, a bass unit 13 housed in the lid 10, and at least two full-range units 12, a substrate
14, an annular wireless charge receiving end 15, and an upper magnetic body 16. A first through
hole 112 and a plurality of second through holes 111 formed around the first through hole 112
are formed in the upper cover portion 11. The lower lid 17 is formed with an annular rib 170. A
storage space 1701 is formed by the rib 170.
[0011]
The bass unit 13 and the two full range units 12 are accommodated in the first through hole 112
and the second through hole 111, respectively. The upper surface of the bass unit 13 is located
above the upper surface of the full range unit 12. The bass unit 13 is positioned below the first
through hole 112 (i.e., does not protrude from the first through hole 112), and is exposed from
the first through hole 112. The entire range unit 12 is located below the second through hole
111 (that is, it does not protrude from the second through hole 111), and is exposed from the
second through hole 111. As shown in FIG. 5, the bass unit 13 is disposed in the upward
direction X. The two full range units 12 are disposed in directions Y and Z inclined with respect

to the upper direction X. The angle between the directions Y, Z and the direction X is less than
90 degrees. An arc-shaped sound field is thereby formed. Sound waves are reflected to the arcshaped enclosed space, generating similar sound quality and volume. Users around the
magnetically levitated speaker 100 hear similar sounds.
[0012]
The substrate 14, the annular wireless charge receiving end 15, and the upper magnetic body 16
are stored in a storage space 1701 of the lower lid 17. The upper magnetic body 16 is
surrounded by the wireless charging receiving end 15. The substrate 14 is disposed on the
wireless charge receiving end 15 and the upper magnetic body 16.
[0013]
As shown in FIGS. 1, 3 and 4, the base 2 includes a shell 20 assembled by a canopy 21 and a
bottom cover 26, an ultra-low tone unit 25 housed in the shell 20, and a circuit board 30. A
Bluetooth (R) module 24 and a speaker unit 29 solder-connected to the circuit board 30, a
controller 27, an annular wireless charging and feeding end 23, a power supply device 28, and a
lower magnetic body 22; Have. The canopy 21 is provided with a holder 210 and a recess 212
for passing an electric wire electrically connected to the charging device. An exposed hole 260 is
formed in the bottom cover 26.
[0014]
The lower magnetic body 22 is surrounded by the wireless charging feed end 23. The lower
magnetic body 22 and the wireless charging feed end 23 are held by the holder 210 of the
canopy 21. The super bass unit 25, the Bluetooth module 24 and the speaker unit 29, the circuit
board 30, and the controller 27 are fixed to the bottom cover 26. The sounds generated from the
lower magnetic body 22 and the super low tone unit 25 are loudened and spread by the speaker
unit 29. The magnetism of the upper magnetic body 16 is different from the magnetism of the
lower magnetic body 22. The super bass unit 25 is exposed from the exposure hole 260. The
canopy unit 21 is provided with an LED module 211.

After the wireless charging feed end 23 of the base 2 is charged, power is provided by the power
provider 28 to provide power to the body 1. The Bluetooth module 24 and the power supply
device 28 are controlled by the substrate 14.
[0016]
As shown in FIGS. 1 and 5, the magnetism of the upper magnetic body 16 of the main body 1 is
different from the magnetism of the lower magnetic body 22 of the base 2. According to the
principle of magnetic mutual exclusion, the body 1 floats on the base 2. As a result, the main
body 1 does not occupy the space of the base 2 and a wide tone range can be obtained. The body
1 is stably floated on the base 2 by the controller 27. By the bass unit 13 and the full range unit
12 being disposed in the main body 1 and the super-basis unit 25 being disposed in the base 2,
the speaker 100 can obtain a good sound effect. When the wireless charging feed end 23 is
electrically connected, the wireless charging feed end 23 charges toward the main body 1. A
wireless charging function is realized. A power supply device 28 is disposed on the base 2. After
the base 2 is charged, power is provided by the power provider 28 to continue to provide power
to the body 1. Even if the base 2 is disconnected from the external power supply, the speaker
100 can be used. The speaker 100 comprises a Bluetooth module 24. The Bluetooth module 24
receives an external audio signal.

Although the present invention has been described in detail with reference to the preferred
embodiments, the embodiments are only exemplary and the present invention is not limited
thereto. Also, the above description is intended to cover any modifications or changes of the
details that can be made based on the present invention within the technical scope of the present
