Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] see figure 2 As shown in , the flower shelf 24 on the back of the ultra-thin speaker provided by the present invention includes a plurality of through holes (or through grooves) around, wherein two through holes are respectively provided with fixing pads 22, 24, and the fixing pads 22, 24 are made of Made of soft insulating material, such as rubber. Two wires 20,21 pass through fixed pads 22,24 respectively to connect the voice coil ( figure 1 Not shown) and wire plate 25.

Abstract

The invention provides an ultrathin loudspeaker which comprises a flower file, a voice coil arranged in the flower file, and a lead board arranged at the back surface of the flower file, wherein the periphery of the flower file comprises at least two through holes which are internally provided with a fixed pad respectively, and leads respectively pass through the fixed pads to be connected with the voice coil and the lead board. In the ultrathin loudspeaker, the fixed pad causes the leads not to collide with the through holes (ventilation window) of the flower file or a centering support chipto generate abnormal voice, and not to generate short circuit due to collision and abrasion, thus improving the fatigue resistance strength of the leads, increasing the power acceptance capability ofthe loudspeaker, prolonging the service life of the loudspeaker, and improving the safety factor; in addition, the service life of a whole LCD TV installed with the loudspeaker is also greatly prolonged.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to an ultrathin loudspeaker structure. Background technique [0002] The general working principle of the speaker is to place the voice coil in the gap of the magnetic field. When the input audio current enters the voice coil through the wire, a force perpendicular to the direction of the magnetic field and current is generated to drive the cone to vibrate and produce sound, thereby realizing electro-acoustic conversion. For example, the appendix of Chinese patent application No. 99201824.2 figure 1 A kind of existing loudspeaker disclosed in, its principle is exactly to lead the electric current of the terminal board into the coil through the wire, drive the sound cone (commonly called the paper cone) on the front of the loudspeaker to make sound, similar to the back structure of this kind of loudspeaker as provided in the present invention of figure 1 As shown in: the back of the lou...
