Problems solved by technology

At present, most of the speakers used in portable electronic devices are dynamic speakers. Due to their principle, dynamic speakers have poor high-frequency transient response and low high-frequency performance, which is difficult to meet the requirements of current Hi-Fi (high-fidelity) equipment. performance requirements
At the same time, with the continuous miniaturization of portable electronic devices, speakers and vibration motors are usually packaged into one housing to form a two-in-one product to reduce the space occupied. However, when making a two-in-one product with a dynamic speaker, only It can be used as a Z-direction motor, that is, the vibration direction of the vibration motor is vertical, which will make the product thicker and cannot meet the requirements of ultra-thin portable electronic devices

Embodiment Construction

[0030] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention.

[0031] The orientation mentioned in this manual refers to the orientation of the sounding unit, and the orientation below refers to the orientation of the vibrator. The inner side referred to in this manual refers to the side close to the center of the moving magnet speaker, and the outer side refers to the side away from the center of the moving magnet loudspeaker. The X direction referred to in this manual refers to the horizontal direction, and the Z direction refers to the vertical direction. .

[0032] Such as figure 1 and figure 2 As shown together, a moving magnet loudspeaker has a rectangular parallelepiped structure, including a casing, a diaphragm and a vibrator accommodated in the casing, and the diaphragm and the vibrator are arranged in parallel. The casing includes a front cover 12 and a casing 10 that are combined up and down. The front cover 12 i...

Abstract

Disclosed is a moving magnet-type loudspeaker, comprising a housing, a vibrating diaphragm and a vibrator arranged in parallel with the vibrating diaphragm being housed in the housing, wherein the vibrator comprises a voice coil; a drive magnet is fixed to one side, close to the vibrator, of the vibrating diaphragm, an electromagnet, formed after the voice coil is electrified, generates an interactive force with the drive magnet to drive the vibrating diaphragm to vibrate and emit sound; a motor magnet is also fixed to one side, close to the vibrator, of the vibrating diaphragm; the voice coil is fixed on a basket, and an elastic support member is respectively fixed at two ends of the basket; the elastic support member is provided with an elastic deformation space along a horizontal direction; and magnetic induction lines of the motor magnet cut the voice coil, pushing the vibrator to vibrate along a horizontal direction. The moving magnet-type loudspeaker in the present invention has a good high-frequency transient response, while also small in thickness, and high in stability and reliability, and is capable of meeting the performance requirements of a Hi-Fi device.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a moving magnet loudspeaker capable of realizing the functions of a loudspeaker and a linear vibration motor. 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. At present, most of the speakers used in portable electronic devices are dynamic speakers. Due to their principle, dynamic speakers have poor high-frequency transient response and low high-frequency performance, which is difficult to meet the requirements of current Hi-Fi (high-fidelity) equipment. performance requirements. At the same time, with the continuous miniaturization ...
