Abstract

A voice diaphragm size rapid and accurate detection system comprises a two-dimensional driving base, an image acquisition device and an image processing module. The two-dimensional driving base is used for bearing a detected voice diaphragm, the image acquisition device is used for photographing the voice diaphragm placed on the two-dimensional driving base, and the image processing module comprises a coordinate positioning module, an image contour calculation module, a voice diaphragm height detection module and a voice diaphragm flatness detection module. The coordinate positioning module is used for setting a two-dimensional coordinate system on the image of the voice diaphragm, the image contour calculation module is used for calculating the contour size of the image of the voice diaphragm, the voice diaphragm height detection module is used for calculating the height of the voice diaphragm, and the voice diaphragm flatness detection module is used for calculating the flatness of the voice diaphragm according to the data in the two-dimensional coordinate system. According to the voice diaphragm size rapid and accurate detection system, manpower can be greatly saved, and the detection accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of winding equipment, in particular to a fast and accurate detection system for the size of a sound film. Background technique [0002] As the main control part of the speaker, the sound film is an integral part of the speaker vibration system and an important part to realize electro-acoustic conversion. When the sound membrane is mass-produced, there are always differences in the vibration amplitude of some sound membranes. When the sound membrane is applied to the earphone, the amplitude of the two sound membranes on the same earphone must be consistent. Current earphone manufacturing manufacturers usually test the vibration amplitude after the earphones are assembled. If the amplitudes of the two sound membranes on the earphones are inconsistent, they need to disassemble the finished product and replace the sound membranes, and then measure until the amplitude of the two sound membranes is assembled. un...
