Abstract

The invention discloses an electroacoustic component. The electroacoustic component comprises a loudspeaker monomer, which includes an inner frame, a top plate, a bottom plate and a vibrating diaphragm, wherein the inner frame is fixed between the top plate and the bottom plate; the periphery of the vibrating diaphragm is fixedly connected on the inner frame; a sound producing cavity is formed between the bottom plate, the inner frame and the vibrating diaphragm; a front sound cavity is formed between the top plate, the inner frame and the vibrating diaphragm; a driving part is arranged insidethe sound producing cavity, wherein the driving part is used for driving the vibrating diaphragm to vibrate; and an outer frame located at the peripheral side of the loudspeaker monomer, wherein a rear sound cavity is formed between the outer frame and the inner frame; the inner frame is provided with a first sound outlet hole and a leakage hole; the first sound outlet hole is located between thevibrating diaphragm and the top plate, and used for communicating the front sound cavity and the outside; and the leakage hole is located between the vibrating diaphragm and the bottom plate, and used for communicating the rear sound cavity and the sound producing cavity. The invention further discloses an electroacoustic device and a mobile terminal.

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...
