The invention discloses an electro-acoustic device and a mobile terminal. The electro-acoustic device comprises a box body, a frame, a vibration diaphragm, a driving component and a sound absorption material; the box body is provided with a sound cavity; the frame is fixed in the sound cavity; a leakage hole passing through the sound cavity is arranged on the periphery of the frame; the vibrationdiaphragm is fixed on the frame; the driving component is contained in the frame, and drives the vibration diaphragm to vibrate; and the sound absorption material is contained in the sound cavity, andpositioned outside the frame so as to absorb sound wave emitted outside the frame through the leakage hole. The sound absorption material can be distributed on the periphery of the frame; the sound absorption material can be prevented from being stacked on the frame; therefore, the thickness of the electro-acoustic device is reduced; and in addition, the user experience is improved.
Description
technical field [0001] The invention relates to the field of electronic equipment, in particular to an electroacoustic device and a mobile terminal. Background technique [0002] At present, the electro-acoustic components of mobile phones are provided with through holes on the relative position of the diaphragm, and the sound-absorbing structure is stacked on the outside of the electro-acoustic component in the direction opposite to the diaphragm. The sound-absorbing structure absorbs part of the sound waves emitted by the diaphragm through the through holes to improve the electric The sound quality of the acoustic components. However, in this structure, the electro-acoustic components are stacked with the sound-absorbing structure, resulting in an increase in the overall thickness of the mobile phone and deteriorating user experience. Contents of the invention [0003] The purpose of the present invention is to provide an electro-acoustic device and a mobile terminal th...
