Abstract
A device for detecting diaphragm tensile force is disclosed. A device comprises a signal generator, a horn, a testing clamp, a frame, a testing microphone and an AC millivoltmeter. The frame is arranged on the testing clamp, a diaphragm is arranged on the frame, the horn connected with the signal generator is arranged below the diaphragm, the testing microphone connected with the AC millivoltmeter is arranged right above the diaphragm, and a compressing switch is arranged on the frame. As the diaphragm can be directly arranged on the frame to accept tensile force detection, diaphragm tensile force can be controlled during a volume production process, and production qualified rate of the diaphragm can be enhanced.
Description
Technical field
The utility model relates to a kind of device that detects vibrating diaphragm tension force.
Background technology
The device that detects vibrating diaphragm tension force at present is the equipment of test monolithic vibrating diaphragm tension force, but it is that the diaphragm of making finished product is detected.This can't be in the volume production processing procedure management and control vibrating diaphragm tension force, therefore just can't make the consistance of finished product satisfy client's demand, also just make the production qualification rate reduction of vibrating diaphragm.
Summary of the invention
The technical matters that the utility model will solve provide a kind of in the volume production processing procedure management and control vibrating diaphragm tension force, improve the device of detection vibrating diaphragm tension force of the production qualification rate of vibrating diaphragm.
The technical scheme that addresses the above problem is: the device of this detection vibrating diaphragm tension force comprises signal generator, loudspeaker, test fixture, the frame that stretches tight, test microphone, ac millivoltmeter; The frame that stretches tight is placed on the test fixture; Vibrating diaphragm is on the frame that stretches tight; The loudspeaker that are connected with signal generator are placed on the below of vibrating diaphragm, the test microphone that is connected with ac millivoltmeter be placed on vibrating diaphragm directly over, the frame that stretches tight is provided with by-pass cock.
Because vibrating diaphragm can be placed directly on the frame that stretches tight and detects tension force, thus can be in the volume production processing procedure management and control vibrating diaphragm tension force, improve the production qualification rate of vibrating diaphragm.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The device of this detection vibrating diaphragm tension force comprises signal generator 1, loudspeaker 2, test fixture 3, the frame 4 that stretches tight, test microphone 5, ac millivoltmeter 6; The frame that stretches tight is placed on the test fixture, and vibrating diaphragm is on the frame that stretches tight, and the loudspeaker that are connected with signal generator are placed on the below of vibrating diaphragm; The test microphone that is connected with ac millivoltmeter be placed on vibrating diaphragm directly over, the frame that stretches tight is provided with by-pass cock 41.
Preferably, the model of said signal generator is XD2B, and the model of said ac millivoltmeter is SX2172.
The method of operating of this device is following:
1, each instrument preheating is 5-10 minute;
2, the test microphone is put into 1.5V, 5# battery 1 joint;
3, the frame that stretches tight that installs vibrating diaphragm is placed on the test fixture, and the test microphone is placed on the top, center of vibrating diaphragm;
4, the output fine tuning of adjustment XD2B type signal generator makes the ac millivoltmeter pointer that certain indicated value arranged;
5, regulate the frame that stretches tight, tighten vibrating diaphragm clockwise, the indication of ac millivoltmeter is risen, and when rising to the highest returning (step-down) phenomenon, vibrating diaphragm is tight.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs to the protection domain of the utility model technical scheme to any simple modification, equivalent variations and modification that above embodiment did.
