Flat panel radiating vibration speaker

Abstract

The present invention discloses a flat radiation vibration loudspeaker. The flat radiation vibration loudspeaker comprises a magnetic circuit driving system, a supporting system and a flat vibration system, and the flat vibration system comprises a flat vibrating diaphragm, spring leaves and coils. The coils in the flat vibration system generate forces moving up and down via the interaction of a permanent magnetic field generated in the magnetic circuit driving system and an electromagnetic field generated in the flat vibration system, and the coils are connected with the flat vibrating diaphragm, so that the flat vibrating diaphragm is driven to do piston motion, and accordingly, the surrounding air is promoted to vibrate to generate sound. The flat radiation vibration loudspeaker of the present invention takes a flat plate as the sounding body, the coils are used as the flat vibration systems for promoting the forces, and a radiation sound wave is transmitted in a non-direction manner, so that the coverage of a sound field is more uniform. The lowest resonant frequency is lower than that of a similar loudspeaker, so that people feel plump when listening to a low frequency. Meanwhile, the flat radiation vibration loudspeaker is thin in appearance, small in size and occupied space and light in weight.

Description

technical field [0001] The invention relates to a flat radiation vibration loudspeaker. Background technique [0002] With the improvement of people's quality of life and the increasing demand for leisure and entertainment, the mass production of notebook computers, desktop computers, tablet computers, mobile phones, ultra-thin LCD TVs, desktop ultra-thin audio and other media has increased the demand for speakers. higher. At present, most of the vibrating systems on the market use conical paper cones, voice coils, and struts. This vibrating system has the advantages of simple manufacture and low cost. The disadvantage is that it is easy to produce modal resonance, large distortion, poor sound quality, and when the parameters and other technical indicators meet the standard, the size of the product itself has many constraints, and the fixed installation space must be large, so in the production process of the media Bring very big difficulty, make cost increase, affect attr...
