Problems solved by technology

This will result in that as long as the coil is energized, the speaker system and the motor system can only work at the same time due to the interaction force and reaction force between the coil and the magnetic circuit.
Unable to meet the diverse application scenarios of mobile phones, such as only ringing without vibrating or only vibrating without ringing, etc.
[0004] To solve this problem, it can only be realized by adjusting the electrical signal, that is, filtering the low-frequency music signal below the res

Abstract

The invention discloses a sound production device and electronic equipment, the sound production device comprises a frame, an elastic support member, and a vibration system, a magnetic circuit system and a coil which are sequentially distributed along the vertical direction, the vibration system comprises a vibrating diaphragm and a voice coil, the edge of the vibrating diaphragm is fixed on the frame, and the edge of the voice coil is fixed on the elastic support member. After being electrified, the voice coil can interact with a magnetic field of the magnetic circuit system to generate a driving force in the vertical direction, so that the vibrating diaphragm vibrates to produce sound; at least part of the magnetic circuit system is supported by the elastic supporting piece to form an oscillator, and the elastic supporting piece has elastic deformation along a first horizontal direction; the coil is fixed relative to the frame, and the coil can interact with the magnetic field of the magnetic circuit system after being powered on to generate driving force in the first horizontal direction, so that the vibrator moves in the first horizontal direction. According to the technical scheme, the sound production function of the loudspeaker and the function of the linear vibration motor can be achieved at the same time, and meanwhile the better tone quality effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of sound energy conversion, in particular to a sound generating device and electronic equipment. Background technique [0002] The loudspeaker is an important acoustic component of portable electronic equipment. It is used to complete the conversion between electrical signals and sound signals. It is an energy conversion device; the linear vibration motor is a kind of motor and an important part of portable electronic equipment. To realize the function of vibration reminder. [0003] In the currently existing two-in-one solution of the speaker and the vibration motor, the speaker and the motor share the same driving coil, and the diaphragm of the speaker and the vibrator of the motor vibrate in the same direction. This will result in that as long as the coil is energized, the speaker system and the motor system can only work at the same time because the coil and the magnetic circuit interact with each other...
