Description
Technical field
The utility model relates to a kind of hummer sound calibration equipment.
Background technology
Hummer is a kind of electronics information ring device of integral structure, adopts DC-voltage supply, is widely used in making microphone device in the electronic products such as computing machine, printer, duplicating machine, alarm, electronic toy, vehicle electronics, telephone set, timer.Hummer is mainly divided into two types of piezo buzzer and electromagnetic buzzers.Electromagnetic buzzer is made up of oscillator, solenoid, magnet, vibrating diaphragm and shell etc.After switching on power, the voice-frequency signalling current that oscillator produces, by solenoid, makes solenoid produce magnetic field.Vibrating diaphragm under the interaction of solenoid and magnet, periodically vibration sounding.
After the production that completes hummer, need to carry out verification to ensure the follow-up normal use of hummer to the sounding of hummer.Existing verification mode is by sounding after hummer energising, after collecting sound frequency signal by microphone, show check results, but because microphone is subject to ectocine at reception sound frequency signal, there is noise and cause check results inaccurate, quality condition that can not effective surface hummer, is not easy to service test.
The problems referred to above are the problems that should pay attention to and solve in hummer sound checking procedure.
Utility model content
The purpose of this utility model is to provide a kind of hummer sound calibration equipment, and to solve existing verification mode be by sounding after hummer energising, after collecting sound frequency signal by microphone, show check results, but because microphone is subject to ectocine at reception sound frequency signal, there is noise and cause check results inaccurate, quality condition that can not effective surface hummer, is not easy to the problem of service test.
Technical solution of the present utility model is:
A kind of hummer sound calibration equipment, comprises hummer to be checked, resistance, frequency counter and power supply, described power supply connect successively described resistance and hummer to be checked, and described resistance is parallel with described frequency counter, and described resistance adopts the resistance of 1-2 Ω.
Preferably, described power supply is connected described hummer to be checked by probe respectively with resistance.
Preferably, described power acquisition 5V direct supply.
A kind of hummer sound of the utility model calibration equipment, by power supply successively resistance in series and hummer to be checked, after using probe connection to switch on, hummer work sounding, the frequency counter of parallel resistance carries out signal collection and processes rear demonstration, and as normal in indication range, this hummer to be checked is up-to-standard, otherwise be substandard product, thereby realize the detection to hummer to be checked.This kind of hummer sound calibration equipment, directly carry out after signal collection is processed showing by the frequency counter of parallel resistance, can ensure in checking procedure, not disturbed by external sound, ensure accuracy and the validity of verification, be beneficial to use, compared with carrying out voice signal collection with existing use microphone, can avoid external interference, and cost is lower, easy to use.
This kind of hummer sound calibration equipment, the resistance of hummer series connection to be checked need select suitable resistance to ensure the validity that testing result shows, and resistance adopts 1-2 Ω, is preferably 1.5 Ω, thereby can ensures the accuracy of testing result.This kind of hummer sound calibration equipment, power supply is connected described hummer to be checked by probe respectively with resistance, connects by probe, is convenient to after the detection that completes hummer, connects fast next hummer to be checked, and easy to operate, detection efficiency is high.This kind of hummer sound calibration equipment, reasonable in design, cost is lower, can ensure the accuracy of the verification to hummer, easy to use.
The beneficial effects of the utility model are: a kind of hummer sound of the utility model calibration equipment, directly carry out after signal collection is processed showing by the frequency counter of parallel resistance, can ensure in checking procedure, not disturbed by external sound, ensure accuracy and the validity of verification, be beneficial to use, compared with carrying out voice signal collection with existing use microphone, can avoid external interference, and cost is lower, easy to use.
