Problems solved by technology
The audio cable is connected to the audio plug and the circuit board, and the resonance cavity is located in the speaker casing. Most of the existing speaker casings are formed in one piece, which is inconvenient to disassemble and maintain. At the same time, it is not possible to use a larger resonance cavity that can significantly improve the sound quality. , otherwise the purpose of portability cannot be achieved

Embodiment Construction
[0019] The present invention will be further described below in conjunction with the drawings and preferred embodiments.
[0020] A miniature sound box of the present invention includes an audio cable, an audio plug, a sound box housing, a speaker, a circuit board, and a resonance cavity. The resonance cavity is hollow, the resonance cavity is a telescopic resonance cavity, and the sound box housing includes a sound box. The shell and the lower shell of the sound box, one end of the telescopic resonance cavity is connected with the upper shell of the sound box, and the other end is connected with the lower shell of the sound box.
[0021] Such as figure 1 and figure 2 As shown, one end of the telescopic resonance cavity 3 is provided with an opening. The horn is located in the telescopic resonance cavity 3. The horn is located in the telescopic resonance cavity 3, saving space (not shown in the horn diagram). Due to the need for sound communication, the telescopic resonance cav...

Disclosed is a mini sound box, comprising an audio line, an audio plug, a sound box casing, a loud speaker, a circuit board, and a resonance cavity. The resonance cavity is hollow and is telescopic. The sound box casing comprises a sound box upper casing and a sound box lower casing, one end of the telescopic resonance cavity is connected to the sound box upper casing, and the other end of the telescopic resonance cavity is connected to the sound box lower casing. According to the present invention, the sound box casing comprises the sound box upper casing and the sound box lower casing, so the sound box can be disassembled more easily, and at the same time, the resonance cavity of the sound box is telescopic, so that acoustic quality of the mini sound box is improved in the premise of occupying the same space.
Description
Technical field [0001] The present invention relates to the field of sound boxes, and more specifically, to a miniature sound box. Background technique [0002] With the continuous development of science and technology, more and more miniature speakers are matched with audio-visual playback systems. Existing miniature speakers usually include audio cables, audio plugs, speaker shells, speakers, circuit boards, and resonance chambers. The audio cable is connected to the audio plug and the circuit board. The resonance cavity is located in the speaker shell. Most of the existing speaker shells are integrally formed, which is not convenient for disassembly and maintenance. At the same time, a larger resonance cavity that can significantly improve the sound quality cannot be used. , Otherwise it will not be portable. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a miniature sound box that can be easily disassembled and has...
