Description

Technical Field

[0001] The utility model relates to the field of speaker technology, in particular to a speaker with a built-in speaker module. Background Art

[0002] The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the audio system, responsible for converting electrical signals into sound signals for people to listen directly. The combination and position distribution of various speakers in the speaker are important factors affecting the sound quality of the speaker.

[0003] In the prior art, a speaker is disclosed, which includes a cabinet, which is provided with a bass cavity and a treble cavity, the bass cavity is provided with a passive radiator and a woofer, and the treble cavity is provided with a tweeter, the tweeter, woofer and passive radiator are arranged in a straight line in sequence and are located on the same side of the cabinet. The speakers of this structure are directly fixed to the cabinet during assembly, and the overall assembly must be completed before testing. When rework is required, the entire cabinet needs to be disassembled, and the disassembly and assembly process is cumbersome, which reduces the production efficiency of the product. In addition, the tweeter, woofer and passive radiator are all facing the same side, and the sound source diffuses in the same direction, resulting in a poor listening experience.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

The speaker module is installed in the accommodating cavity of the speaker shell through the cooperation of the guide groove and the guide rail, which facilitates the assembly of the speaker module. The first cover and the second cover are installed on the speaker shell through the mounting hole. The guide rail can be used by the speaker module, the first cover and the second cover at the same time. The structural design is ingenious, and the speaker module is made into an integral setting separately, which can be tested separately without the need to complete the assembly of the entire speaker before testing, reducing the time spent on disassembly and assembly during rework and improving the production efficiency of the product. In addition, the low-frequency speaker emits sound downward to the surroundings, emphasizing the auditory experience of the heavy bass sound source spreading to the surroundings. The passive radiator and the high-frequency speaker are side by side to form a linear array layout, which neutralizes the auditory experience of the sound source of the treble part and improves the overall auditory experience of the speaker.
