Embodiment Construction

[0008] The structure and application process of the present invention will be further described below in conjunction with the accompanying drawings: the bottom layer of the plastic bracket 2 in the figure is provided with two symmetrically distributed lower splints 5, and two left-right symmetrically distributed rare earth magnets are arranged on the lower splint 5 4. On top of the two rare earth magnets 4, there are two upper splints 3 symmetrically distributed left and right. The plastic bracket, the magnets and the upper and lower splints are bonded with glue; The middle of the sound cone 1 is bonded, the composite edge flat sound cone 1 is bonded to the upper edge of the plastic support 2, and the flat double-layer voice coil 6 is suspended in the gap between the two splints. The lower end surface of the flat double-layer voice coil 6 is bonded to the middle of the positioning support piece 7, the edge of the positioning support piece 7 is bonded to the bottom of the plasti...

Abstract

The invention provides a double-magnetic circuit double-voice coil flat plane speaker, technical features thereof comprise: two lower clamp plates which are symmetrically distributed left and right are mounted on bottom layer within a plastic frame, two rare-earth magnetic steels are mounted on upper surfaces of the lower clamp plates, two upper clamp plates which are symmetrically distributed left and right are mounted on the rare-earth magnetic steels; upper end surface of the flat plane double-layer voice coil is stuck with a composite flat plane voice basin which is stuck with the elastic frame; lower end surface of the flat plane double-layer voice coil is stuck in the middle of a positioning support chip, two leading wires in the flat plane double-layer voice coil is welded with a knitting leading wire by running through the positioning support chip; the flat plane double-layer voice coil starts to vibrate and drives the flat plane voice basin to vibrate and make a sound when audio signals is input to the knitting leading wire. The invention is provided with compact structure, small volume, light weight, high electroacoustic conversion efficiency of loudspeaker, good sound quality etc.

Description

1. Technical field: [0001] The invention belongs to the technical field of loudspeakers, in particular to a flat-panel loudspeaker with double magnetic circuits and double voice coils. 2. Background technology: [0002] At present, there are many types of speakers produced in the speaker field. Traditional speakers include electromagnetic, piezoelectric, capacitive, and electric. The mainstream is the electric speaker, and its structure generally adopts single magnetic circuit, single voice coil, cone Cone structure. With the development of new products such as digital LCD TVs, plasma TVs, and car audio, the disadvantages of traditional speakers are heavy weight, environmental protection, large volume, and low electroacoustic conversion efficiency, which greatly restricts the application of speakers. 3. Contents of the invention: [0003] In order to overcome the disadvantages of the above-mentioned traditional loudspeaker, such as heavy weight, not environmental protecti...
