Description

Technical Field

[0001] The utility model relates to the technical field of cluster speakers, in particular to a multi-purpose cluster speaker with wireless audio transmission. Background Art

[0002] As a commonly used sound-producing component in modern times, the main function of cluster speakers is that when audio information is transmitted to the inside of the cluster speakers, the cluster speakers cannot transmit the sound to the external environment. However, the existing cluster speakers lack shock-absorbing auxiliary components. During the use of the cluster speakers, they cannot absorb the vibrations generated by the sound playback according to the needs, resulting in high-frequency vibrations in the cluster speakers, which in turn affects the sound quality of the cluster speakers.

[0003] Compared with the existing cluster speakers, the utility model adds a shock-absorbing auxiliary component, which can absorb the vibration generated by sound playback during the use of the cluster speakers, prevent the cluster speakers from resonating, and thus improve the sound quality of the cluster speakers. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-purpose cluster speaker for wireless audio transmission to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: comprising a fixed shell and a sound module, wherein nine groups of sound modules are embedded and installed on the outer surface of the fixed shell;

[0006] A shock-absorbing layer is arranged inside the inner wall of the fixed shell, and a sound-absorbing layer is arranged inside the fixed shell.

[0007] Preferably, nine groups of ventilation shells are installed on the inner side of the fixed shell.

[0008] Preferably, a plurality of ventilation holes are formed through the outer surface of the ventilation shell, and an interception net is installed on the inner side of the ventilation shell.

[0009] Preferably, a power connection line is installed on the back of the fixed shell, and the power connection line is located below the ventilation shell.

[0010] Preferably, a power plug is installed at the tail end of the power connection line.

[0011] Preferably, a control module is embedded and installed on the back side of the fixed shell, and the control module is located above the ventilation shell.

[0012] Preferably, two groups of wireless transceivers are installed on the back side of the fixed shell.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is equipped with a shock-absorbing layer and a sound-absorbing layer. The shock-absorbing layer is made of liquid resin. When the impact force in the external environment is transmitted to the inside of the fixed shell, the liquid resin inside the shock-absorbing layer fluctuates through the damping effect, thereby absorbing the impact force and reducing the resonance of the sound shell. The sound-absorbing layer is made of silicone material and installed inside the fixed shell. When the air generated by the sound hits the inside of the sound-absorbing layer, the sound-absorbing layer guides the vibration generated by the air, further reducing the resonance of the sound shell, thereby improving the sound effect of the cluster sound.
