Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the relationship between the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second" and so on in the...

Abstract

The invention discloses a sound production device and electronic equipment, the sound production device comprises a shell, and a magnetic circuit system, a vibration system, a coil and an elastic support member which are accommodated in the shell, the magnetic circuit system comprises a first magnet part and a second magnet part which are arranged at an interval to form a magnetic gap; the vibration system comprises a vibrating diaphragm and a flat voice coil for driving the vibrating diaphragm to vibrate, the vibrating diaphragm is connected with the shell, the flat voice coil is located in the magnetic gap, the axial direction of the flat voice coil is perpendicular to the vibration direction of the vibrating diaphragm, and the flat voice coil is located in the magnetic gap; the elastic supporting piece supports the magnetic circuit system to form a vibrator, the elastic supporting piece has elastic deformation along a first direction, and the first direction is perpendicular to the axial direction and the vibration direction of the flat voice coil; the coil is fixed relative to the shell and can interact with the magnetic field of the magnetic circuit system after being powered on to generate driving force in the first direction, so that the vibrator moves in the first direction. According to the technical scheme, the sound production function and the linear vibration motor function can be achieved, and meanwhile the sound production performance and the motor performance are improved.

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] Due to the consideration of portability, comfort, and aesthetics, electronic devices, such as mobile phones or wearable smart terminals, have relatively strict size requirements, and the size and thickness tend to be miniaturized. Therefore, after removing various main components such as chips, batteries, and motherboards, there is very little space for built-in speakers and motors, which makes it difficult to improve the perfo...
