Problems solved by technology

This patent uses metal wires sewn on the surface of the wave structure, which is also complicated to manufacture, and the metal wire itself has hardness, which can easily suppress the amplitude and compliance of the entire elastic wave vibration. In addition, the outer surface of the metal wire needs a protective layer, which increases the thickness. and hardness, affecting the thickness and weight of the entire elastic wave, and the cost is higher

Embodiment Construction

[0015] Such as figure 1 , figure 2 As shown, the loudspeaker of the present invention conducts elastic waves, which are horizontally arranged in the basin frame of the loudspeaker. It is composed of an elastic wave main body 1 corresponding to the central voice coil. There are crests and troughs and a voice coil 2. The surface of the main body of the elastic wave is covered with a strip-shaped FPC board 3 (flexible circuit board). One end of the FPC board 3 is connected to the voice coil, and the other end is provided with a connecting terminal. The outside of the spring body protrudes to connect to the power supply. The FPC board 3 and the elastic wave main body 1 are connected in an integral way by hot pressing. There are two FPC boards 3 arranged vertically on the elastic wave surface, that is, one on the right side and one on the upper side. The rated current of the connecting end of the FPC board is 0.5 ampere or 1 ampere, and conductive coatings arranged at intervals...

Abstract

The invention discloses a conductive elastic wave for a loudspeaker, which comprises an elastic wave main body, wherein a wave peak, a wave trough and a voice coil are arranged on the elastic wave main body; and the cross section is of a wave structure. The conductive elastic wave for the loudspeaker is characterized in that two or a plurality of FPCs (Flexible Printed Circuit) are arranged on the wave peak and the wave trough of the elastic wave; one end of each of the FPCs are connected with the voice coil; a connecting end is arranged at the other end of each of the FPCs; a connecting power supply stretches out from the outer side of the elastic wave main body; the FPCs are connected with the elastic wave main body integrally in the way of hot-pressing, or penetration or sewing; and two of the FPCs are arranged vertically on the surface of the elastic wave. The thickness of each FPC is 0.01mm-2mm, and the conductive elastic wave for the loudspeaker has the advantages of simple structure, low production cost, good effect and the like.

Description

technical field [0001] The invention relates to the field of loudspeaker accessories, in particular to a conductive elastic wave of a loudspeaker with simple structure and low cost. Background technique [0002] The existing loudspeaker wave generally adopts a ring-shaped corrugated vibrating plate with a wavy radial section, which is arranged between the pot frame and the paper cone to support the voice coil and play a role in pulling the drum paper for directional vibration. etc., the connecting wire is often made of brocade thread, which is sewn and woven on the surface of the elastic wave. Due to the thickness and weight of the brocade silk thread, and the space for installing audio in the current product is very limited, the elastic wave is also thicker. Heavier, limited installation, and higher cost. For example, the application number is CN03225547.0, the application date is April 28, 2003, and the patent name is an improved elastic wave structure, which is character...
