Abstract

The invention provides a sound production device, which comprises a shell and a vibration assembly, and is characterized in that the vibration assembly comprises a diaphragm and a voice coil, the voice coil is of a hollow columnar structure, and the diaphragm is combined on one end surface of the voice coil; the loudspeaker further comprises a system stabilizing part. The system stabilizing part is combined on the end face of the voice coil or combined on the side wall of the voice coil. The system stabilizing part is of a linear structure, is formed by winding a metal wire, and comprises a first connecting part connected with the voice coil, a deformation part and a second connecting part connected with the shell. The invention further provides electronic equipment which comprises the sound production device. By adopting the sounding device with the structure, the voice coil cannot be polarized under the condition of large displacement, and the free vibration of the voice coil cannotbe hindered by the system stabilizing part with the novel structure. The electronic equipment adopting the sound production device has a good bass effect and good acoustic performance.

Description

technical field [0001] The invention belongs to the field of electroacoustics, and in particular relates to a sounding device and electronic equipment thereof. Background technique [0002] The sound generating device is an important acoustic component in electronic equipment, which is a transducer device that converts electrical signals into acoustic signals. The existing sound generating device includes a casing, and a magnetic circuit system and a vibrating assembly arranged in the casing. [0003] Among them, the voice coil of the vibration component is prone to polarization in the non-vibration direction during the vibration process. In order to prevent polarization, a system stabilizer connected to the voice coil is usually provided. The system stabilizer of the existing structure is an integrated sheet structure. The system stabilizer with a sheet structure is combined with one end of the voice coil to prevent polarization. [0004] However, the system stabilizer wi...
