Embodiment Construction

[0026] In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It will be apparent, however, that the embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.

[0027] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] In view of the problem that the diaphragm compliance cannot be obtained independently in the aforementioned existing test methods, and the problem that the test process is easily disturbed by the surrounding environment, the present invention places the diaphragm in a closed space to perform the diaphragm compliance test. The relevant parameters of the diaphragm compliance are calculated according to the calcula...

Abstract

The invention provides a method and a system for acquiring diaphragm compliance. The diaphragm compliance is acquired through a sealed space comprising a structural cavity and a diaphragm. The method includes the steps: acquiring the diaphragm compliance according to displacement generated in vibration of a diaphragm and pressure applied to the diaphragm in vibration; converting externally inputted electric signals into acoustic signals and vibrating the diaphragm; acquiring the displacement generated in vibration of the diaphragm and acoustic pressure in the sealed space; multiplying the acquired acoustic pressure by the acoustic pressure covering area of the diaphragm to obtain the pressure applied to the diaphragm in vibration, and dividing the acquired displacement by the pressure applied to the diaphragm in vibration to obtain the diaphragm compliance. According to the method and the system for acquiring the diaphragm compliance, the diaphragm compliance can be independently tested in a sealed environment without being interfered by a surrounding environment or affected by diaphragm quality factors, so that the diaphragm compliance is more directly tested and higher in confidence.

Description

technical field [0001] The invention relates to the technical field of the diaphragm of a receiver, and more particularly, to a method and a system for obtaining the compliance of the diaphragm. Background technique [0002] With the rapid development of science and technology, the requirements for sound-emitting devices are getting higher and higher. As the core component of the sound-emitting device, the performance of the diaphragm directly affects the performance of the sound-emitting device. [0003] One of the most important factors to measure the performance of the diaphragm is the compliance of the diaphragm. In the prior art, the compliance of the diaphragm is obtained by testing the self-resonant frequency of the diaphragm after molding. The self-resonant frequency is the result of the combined action of the quality of the diaphragm and the compliance of the diaphragm. The existing test method requires the diaphragm to be placed in an unsealed environment, and the ...
