Abstract

The present invention is applied to the loudspeaker technology field, and provides a planar diaphragm loudspeaker the planar diaphragm loudspeaker comprises a vibration system and a magnetic field system. The vibration system includes a diaphragm conductor assembly, an upper gasket and a lower gasket, and the upper gasket is provided with two via holes; and the diaphragm conductor assembly includes a diaphragm body, a coating layer and a conduction structure which is formed by winding of wires in the double helix mode and has two free ends respectively corresponding to the two via holes of the upper gasket. The planar diaphragm loudspeaker coats a coating layer at the surface of the diaphragm body to enhance the weight of the central area of the diaphragm body and improve the low-frequency sound effect; and wires are wound at the surface of the coating layer in the double helix mode to allow the conductor structure formed through winding to complete cover the coating layer and fill the area of the diaphragm body to allow the diaphragm body to be fully utilized and allow the whole stress driving aiming at the system to obtain the maximum utilization so as to greatly improve the sensitivity of the planar diaphragm loudspeaker.

Description

technical field [0001] The invention belongs to the technical field of loudspeakers, in particular to a plane diaphragm loudspeaker. Background technique [0002] Loudspeaker, also known as "horn", is a very commonly used electro-acoustic transducer device, and it is widely used in electronic and electrical equipment that emits sound. Dynamic speakers, also known as dynamic speakers, are electro-acoustic transducers that use electric distance. Electrodynamic loudspeakers are widely favored by users because of their simple structure, easy production, and excellent performance. They are currently the most widely used loudspeakers. [0003] The planar diaphragm speaker is a kind of loudspeaker. The traditional planar diaphragm speaker is generally composed of a plurality of bar magnets sandwiching the planar diaphragm in the middle. There are the following problems in its manufacture: the fixing of multiple magnets , special fixtures are required, otherwise the dislocation of...
