Embodiment Construction

[0032] The core of the present invention is to provide a magnetic levitation speaker, which enhances the stability of the suspension of the float part of the magnetic levitation speaker and improves the sound quality of playing music.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] figure 1 It is a schematic structural diagram of a magnetic levitation sound box provided by an embodiment of the present invention. Such as figure 1 As shown, the magnetic levitation sound box includes a base 1 and a ...

Abstract

The invention discloses a magnetic suspension speaker. The magnetic suspension speaker comprises a base and a speaker, a first coil arranged on the base, and a loudspeaker arranged on the speaker, andfurther comprises a permanent magnet arranged on the speaker, wherein the magnetic pole of the permanent magnet close to the base is the same as the magnetic pole close to the speaker generated afterthe first coil is energized. By using the magnetic field force that is generated by the homopolar repulsion between the permanent magnet and the first coil of the base and is opposite to the gravitydirection of the speaker, the magnetic steel of the loudspeaker does not need to undertake the task of suspending the speaker, so that the sound quality of the speaker cannot be affected by the interference of the suspension force, the speaker also cannot be affected by the playing music during suspension, and thus the stability of the speaker suspension can be improved.

Description

technical field [0001] The invention relates to the field of electronic appliances, in particular to a magnetic levitation sound box. Background technique [0002] The magnetic levitation speaker suspends the speaker in the air through electromagnetic force, which greatly increases the user's audio-visual experience. [0003] The magnetic levitation sound box in the prior art includes a base and a sound box as a float. There is a coil in the base, and a magnetic field is generated after electrification. The electromagnetic force that opposes gravity keeps the speaker floating in the air. [0004] However, using the magnetism of the magnetic steel in the speaker to suspend the speaker, when the speaker plays music, not only will the magnetic field be disturbed, but also the sound quality of the played music will be affected. [0005] Therefore, how to enhance the suspension stability of the speaker portion of the magnetic levitation speaker and improve the sound quality of ...
