Taiwan Utility Model No. M486920 specification
[0004]
The voice is transmitted upward by arranging the prior art magnetic floating speaker upward.
Therefore, when the user is located around the magnetically floated speaker, the sound effect is
not good.
[0005]
Therefore, an object of the present invention is to provide a magnetically levitated speaker
capable of obtaining a good sound effect.
[0006]
In order to achieve the above object, the magnetically levitated speaker of the present invention
comprises a base and a main body.
The base floats on the base including a base having a shale, a controller and a lower magnetic
body housed in the shale, and the base. The main body includes a lid, and a main body having a
single low-pitched sound contained in the lid, at least two single-range full-pitch single-ranges
disposed around the single low-pitched sound, and an upper magnetic body. The magnetism of
the upper magnetic body is different from the magnetism of the lower magnetic body. The single
bass is disposed in a first direction, and the two full pitch singles are disposed in a second
direction and a third direction inclined with respect to the first direction, respectively. The angles
between the three directions and the first direction are each less than 90 degrees.

Compared to the prior art, the invention has the following advantages. The single bass is
disposed in the first direction, and the two full range singles are disposed in the second and third
directions of inclination. An angle between the second direction and the third direction and the
first direction is smaller than 90 degrees. An arc-shaped sound field is thereby formed. Sound
waves are reflected to the arc-shaped enclosed space, and similar sound quality and volume are
generated. The user around the magnetic float speaker hears a similar voice.

[0009]
As shown in FIG. 1 and FIG. 5, the magnetically levitated speaker 100 of the present invention
comprises a base 2 placed 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 the upper lid 11 and
the lower lid 17, a single bass 13 housed in the lid 10, and at least two full pitch singles 12. , A
substrate 14, an annular wireless charging 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 lid portion 11. The lower lid 17 is formed with an
annular rib 170. A storage space 1701 is formed by the rib 170.

The low sound unit 13 and the two full range units 12 are respectively accommodated in the first
through hole 112 and the second through hole 111. The upper surface of the single low-pitched
sound 13 protrudes upward with respect to the upper surface of the full-pitch range single-piece
12. The single low-pitched sound 13 is located below the first through hole 112 and is exposed
from the first through hole 112. The entire sound range unit 12 is positioned below the second
through hole 111 and is exposed from the second through hole 111. As shown in FIG. 5, the
single bass 13 is disposed in the upward direction X. The two full range units 12 are disposed in
the directions of inclination Y and Z, respectively. 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 arc-shaped enclosed space, and similar sound quality and volume are
generated. The user around the magnetically levitated speaker 100 hears a similar sound.
[0012]
The substrate 14, the wireless charge receiving end 15, and the upper magnetic body 16 are
stored in a storage space 1701 of the lower cover 17. The upper magnetic body 16 is
surrounded by the wireless charging receiving end 15. The substrate 14 is disposed on the
wireless charging receiving end 15 and the upper magnetic body 16.
[0013]
As shown in FIG. 1, FIG. 3 and FIG. 4, the base 2 is a shale 20 assembled by a canopy 21 and a
bottom cover 26, an ultra-low tone single unit 25 housed in the shale 20, and a circuit board 30.
It has a Bluetooth module 24 and a speaker unit 29 solder-connected to the circuit board 30, a
controller 27, an annular wireless charging transmitting end 23, a storage device 28, and a lower
magnetic body 22. The canopy 21 is provided with a holder 210. The bottom cover 26 is formed
with an exposure hole 260 and a recess 212 for passing a charging device and an electric
connection wire.
[0014]
The lower magnetic body 22 is surrounded by the wireless charging transmitting end 23. The
09-05-2019

lower magnetic body 22 and the wireless charging transmitting end 23 are held by the holding
unit 210 of the canopy 21. The super-low bass 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 sound
generated from the lower magnetic body 22 and the ultra-low bass single body 25 is diffused 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 low tone single unit 25 is exposed from the
exposure hole 260. The canopy unit 21 is provided with an LED module 211.
[0015]
After the bottom cover 26 is charged, electricity is stored by the storage device 28 and electricity
is provided to the main body 1. The Bluetooth module 24 and the storage 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. The body 1 floats on
the base 2 according to the principle that magnetism repels each other. Thereby, the main body
1 does not occupy the space of the base 2, and a wide sound range can be obtained. The main
body 1 is stably floated on the base 2 by the controller 27. The low sound single body 13 and the
full sound range single body 12 are disposed in the main body 1, and the ultra low sound single
body 25 is disposed in the base 2, whereby the speaker 100 can obtain a good acoustic effect.
When the wireless charging transmitter 23 is electrically connected, the wireless charging
transmitter 23 charges the main body 1 to realize a wireless charging function. A power storage
device 28 is disposed on the base 2. After the base 2 is charged, electricity is stored by the
storage device 28 and electricity continues to be provided to the main body 1. The speaker 100
can be used even when the base 2 is removed from the external power source. The speaker 100
comprises a Bluetooth module 24. The Bluetooth module 24 receives an external sound signal.
