This disclosure is about a loudspeaker, particularly a loudspeaker equipped with a mount.

Loudspeaker, also known as horn, sound. It is a transducer and electronic component that converts electronic signals into sound. Generally, a sound group can be composed of a single or multiple speakers. In order to provide the effect of all-round balanced radiation, it is necessary to adjust the spatial distribution and orientation of the speakers. However, the conventional loudspeakers all use an additional fixing seat, which is not only easy to damage the resonant cavity of the loudspeaker due to improper locking or riveting, thereby affecting the depth and clarity of the sound effect. In addition, once the fixed seat is locked with the speaker, it is not easy to adjust the orientation, which greatly reduces the freedom of space allocation and orientation adjustment when installing the speaker.

Therefore, there is a need to provide an advanced loudspeaker with built-in mounts to solve the problems faced by the prior art.
