Description

Technical Field

[0001] The invention belongs to the technical field of sound boxes, in particular to a hidden hanging sound box. Background Art

[0002] A speaker is a device that can convert audio signals into sound. Generally speaking, it means that the speaker main box or subwoofer box has a built-in power amplifier, which amplifies the audio signal and then plays back the sound, making the sound louder. Hanging speakers are designed to save space and make the sound travel farther.

[0003] The prior art also proposes some improvement schemes for the hanging speakers. For example, a patent application with the publication number CN218734733U discloses a hanging shock-absorbing speaker. Since the outer shell is set outside the sound cavity, and the sound cavity is suspended inside the outer shell, and the outer shell and the sound cavity are flexibly connected through a plurality of shock-absorbing balls, the sound cavity and the outer shell can achieve flexible contact, so that the vibration of the sound cavity located on one side of the speaker is greatly weakened by the shock-absorbing balls before the remaining vibration energy is transmitted to the outer shell, so that the vibration interference received by the microphone during sound reception can be greatly reduced, thereby greatly improving the sound reception quality of the microphone. And because the structure of the hanging shock-absorbing speaker is simple, its parts are only three large parts, namely the outer shell, the sound cavity and the shock-absorbing balls, so that there are fewer parts in the hanging shock-absorbing speaker, fewer parts need to be installed, and the occurrence of defective products in manufacturing and abnormalities in use will be greatly reduced, making the disassembly and assembly of the hanging shock-absorbing speaker simpler, thereby greatly reducing the production and manufacturing costs of the hanging shock-absorbing speaker.

[0004] Although the above technical solution solves the problem of speaker vibration, there are still other problems in specific use. For example, when the speaker is hung, the speaker is exposed to the outside, but because some places are relatively humid and the speaker is hung at a high position, the speaker cannot be protected, which reduces the service life of the speaker.

[0005] To this end, the present invention provides a hidden hanging speaker. Summary of the invention

The normal use of the speaker components inside the sound main body 3 is avoided; when the sound main body 3 needs to be used, the shielding frame 1 4 and the shielding frame 2 5 are driven to move in opposite directions by controlling the driving mechanism, so that the shielding frame 1 4 and the shielding frame 2 5 move away from the outside of the sound main body 3, and then the shielding frame 1 4 and the shielding frame 2 5 are completely away from the sound main body 3, and then under the action of the driving mechanism, the sound main body 3 can be pushed out of the wall main body 1, so that the sound main body 3 is used, and the operation is relatively convenient;
