Abstract

An electroacoustic assembly disclosed by the present invention comprises a loudspeaker monomer and a box body, the loudspeaker monomer is accommodated in the box body and comprises a frame and a first actuator, and a back sound cavity is formed between the frame and the box body and is located at the circumferential side of the loudspeaker monomer. A first leakage hole is arranged on the frame and enables the back sound cavity to be communicated with a sounding cavity in the loudspeaker monomer, the first actuator is located in the sounding cavity and is fixedly connected with the frame, and the vertical projection of the first actuator on the frame is staggered with the first leakage hole. The present invention also discloses an electroacoustic device and a mobile terminal. According to the present invention, the thickness dimension of the electroacoustic assembly is reduced, the first actuator is fixed on the frame and is staggered with the first leakage hole, thereby not shielding a flow path of a gas, facilitating the light and thin design of a product, and improving the user experiences.

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, users are more and more interested in thinner and lighter mobile terminal designs. Electroacoustic components are an indispensable part of mobile terminals, and the thickness requirements of electroacoustic components are also getting higher and higher. At present, the dynamic electro-acoustic components design the leakage holes at the bottom of the electro-acoustic components. The electro-acoustic components include the interconnected sound cavity and the back sound cavity, the thickness of the sound cavity, the thickness of the back sound cavity, and the thickness of the sound cavity and the back sound cavity. The connection mode of the cavity directly affects the thickness of the electroacoustic com...
