Embodiment

[0023] Example: see Figure 4 with Figure 5 In the electrodynamic loudspeaker of the embodiment of the present invention, a vibrating membrane 1 is bonded to a ring 6, and the ring 6 is bonded to a bracket 5, and a voice coil tube 3 is bonded to the above-mentioned vibrating ring through a coupler 2. On the bottom surface of the film 1, the voice coil tube 3 and the voice coil coil 4 surrounding it are suspended in a magnetic circuit, and the magnetic circuit has three washers 8 with the same diameter, a magnet 9, a spacer 10 and surrounding the three same diameters. The U-shaped iron 11 of the radial part is composed of a spring wave 14 perpendicular to the diaphragm 1, one end of which is bonded to the bottom surface of the diaphragm 1, and the other end is bonded to the bracket 5.

[0024] The function of this dynamic loudspeaker is the same as that of the traditional dynamic loudspeaker. The voice coil tube 3 and the magnetic circuit convert the electrical input signal i...

Abstract

The invention provides an electro-dynamic loudspeaker, which comprises a vibrating diaphragm, a voice coil, a magnetic circuit, a support and two types of movable hanging components, wherein one type of the movable hanging components is a folded ring surrounding the vibrating diaphragm, and the other type of the movable hanging components is a group of elastic waves vertical to the vibrating diaphragm; and the upper ends of the elastic waves are adhered to the bottom surface of the vibrating diaphragm, the lower ends of the elastic waves are adhered to the support, and the adhering points are positioned outside the voice coil and outside the outer diameter of the magnetic circuit. The electro-dynamic loudspeaker with the structure is thinner, without additional connectors and magnetic circuit components.

Description

technical field [0001] The invention relates to an electrodynamic loudspeaker. Background technique [0002] The dynamic loudspeaker of general structure see figure 1 , usually consists of a diaphragm 1, a voice coil, a magnetic circuit, a bracket 5 and two movable suspension parts, the suspension part is a ring 6 and an elastic wave 7 parallel to the diaphragm. The voice coil is composed of a voice coil tube 3 and a voice coil coil 4 wound outside the lower part of the voice coil tube 3, the magnetic circuit is composed of a washer 8, a magnet 9, a gasket 10, and a U-shaped iron 11 surrounding the above three components, and 12 sets of copper caps Outside of Washer 8 and Magnet 9. The ring 6 makes the diaphragm 1 hang on the bracket 5, the upper end of the voice coil tube 3 is bonded to the diaphragm 1, and the elastic wave 7 makes the voice coil tube 3 properly and concentrically suspended in the magnetic circuit. The hardness balance between the surround 6 and the elas...
