The invention discloses an electroacoustic component fixed on a circuit board, comprising: a loudspeaker monomer, wherein the loudspeaker monomer comprises a bottom plate, an inner frame and a vibrating diaphragm, the inner frame is fixed on the bottom plate, the bottom plate is fixedly connected with the circuit board, the peripheral edge of the vibrating diaphragm is fixedly connected to the inner frame, and a sound production cavity is formed between the inner frame and the vibrating diaphragm; an outer frame located on the periphery of the loudspeaker monomer, wherein the outer frame comprises an outer top plate, an outer bottom plate, and an outer plate connected between the outer top plate and the outer bottom plate, the outer top plate abuts against the vibrating diaphragm, a rear sound cavity is formed among the outer top plate, the outer side plate, and the outer bottom plate, a leakage hole is formed in the inner frame for communicating the rear sound cavity with the sound production cavity, and the vertical distance between the outer bottom plate and the outer top plate is smaller than the vertical distance between the vibrating diaphragm and the bottom plate. The invention further discloses an electroacoustic device and a mobile terminal. The sound quality effect of the electroacoustic component is optimized.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an electroacoustic component, an electroacoustic device and a mobile terminal. Background technique [0002] As mobile terminal products are more and more widely used, the functions of the mobile terminal are also becoming more and more diverse. The mobile terminal is no longer just a tool for calling, but also an entertainment device for playing video and music. Therefore, the sound quality of music played by the mobile terminal also greatly affects the user experience. The electro-acoustic component is the main device for playing sound in the mobile terminal. At present, the dynamic electro-acoustic component is the most common type of electro-acoustic component applied to the mobile terminal. [0003] In the prior art, in order to meet the light and thin design of the mobile terminal, the thickness of the electroacoustic component is small, and the sound from the...
