Vibration loudspeaker

Abstract

The invention discloses a vibration loudspeaker. A vibration unit of the vibration loudspeaker comprises a square magnetic circuit system and a metal dome used for suspending the magnetic circuit system in an auxiliary system. The metal dome comprises a squarely annular central part, a first elastic arm and a second elastic arm, wherein the central part is sleeved on the periphery of a magnetic conducting part, fixed on a magnetic conducting base corresponding to a magnetic interval, and is provided with a first side and a second side which are opposite to each other; the first elastic arm is led out of the first side of the central part, and is bent and extended along the first side of the central part; the end part of the first elastic arm is fixed on a plastic shell of the auxiliary system; the second elastic arm is led out of the second side of the central part, and is bent and extended along the second side of the central part; and the end part of the second elastic arm is fixed on the plastic shell of the auxiliary system. The vibration loudspeaker can provide stable vibration feel at the same time of improving product performance by increasing the magnet size of the magnetic circuit system.

Description

technical field [0001] The invention relates to the technical field of vibration speakers. Background technique [0002] With the development of portable terminal consumer electronics products, people's functional requirements for products are becoming stronger and stronger. In the functions of mobile phone music appreciation, in order to make the entertainment effect stronger, there have been mobile phones with vibration while playing music. mode, the performance requirements for speakers with vibration function are gradually increasing. [0003] As is known, the vibration speaker mainly suspends the magnetic circuit system by sheathing an elastic piece on the fixed magnetic circuit in the traditional speaker product, and increases the vibration feeling by sheathing a mass block on the magnetic circuit system. When the vibration speaker When there is a high-frequency audio signal in the middle pass, because the mass of the suspended part such as the magnetic circuit system...

AI Technical Summary

Problems solved by technology

[0004] In the shrapnel technology of the traditional structure, in order to facilitate the design and fixation, the shrapnel is generally set in a circular shape and sleeved on the edge of the magnetic circuit system, and the corresponding magnetic circuit system is also set in a circular shape. This design, the circular structure Vibration speakers require a larger installation space. As the volume of portable electronic devices such as mobile phones decreases, the volume of corresponding vibration speakers continues to decrease. The size of the magnet is limited, which will affect the output volume and sound quality of the vibration speaker
