Abstract

The invention discloses an elastic component and a sound production device. The elastic component is at least partially formed by a narrow and long conductor, one end of the elastic component is installed on a reciprocating vibration coil, and the elastic component elastically restrains the coil according to the vibration offset state of the coil, so that the coil is stabilized in a preset central area; the elastic component comprises a first connecting part, a second connecting part and a deformation part, and the first connecting part is configured to be electrically connected and matched with a wiring part of a coil of the sound production device and is used for transmitting an external electric signal to the coil through a conductor on the elastic component; the second connecting part is configured to be fixedly connected in the sound production device and is used for connecting an external circuit; the deformation part is located between the first connecting part and the second connecting part and connected with the first connecting part and the second connecting part, the body structure of the deformation part elastically stretches out and draws back, and when the coil reciprocates in the vibration direction, the deformation part elastically deforms under the extrusion / stretching acting force of coil movement; and the cross section of the elastic component is non-circular.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, and more specifically, to an elastic component and a sound generating device. Background technique [0002] As an electro-acoustic conversion device, the sound generating device is widely used in electronic terminal products such as mobile phones, earphones, PADs, tablets, smart audio, and car audio. With the continuous advancement and innovation of technology, the development of electronic terminal products tends to be more and more miniaturized, thinner, and functionally integrated. This poses a fundamental problem for the design of current sounding devices: how to Further optimize the acoustic performance in the space. [0003] The sound generating device is driven by the magnetic circuit and the electric signal, and the coil drives the diaphragm to vibrate, thereby instigating the air and radiating sound waves to the outside world. On the one hand, conductive parts (such ...
