The striking type electromagnetic buzzer is clear in sound, stable in structure, not subjected to damage, and long in service life.
Description
technical field:
The utility model relates to a kind of hummer, is specifically related to a kind of beating type electric magnetic buzzer.
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.The hummer of this vibrating diaphragm sounding is owing to being subject to the impact of the factors such as the material of vibrating diaphragm, the sound sending is clear and melodious not, and hummer diaphragm is cracked is one of principal mode of hummer inefficacy, causes the serviceable life of hummer short, and this is the important topic of research of technique in industry.
summary of the invention:
The purpose of this utility model is to provide a kind of beating type electric magnetic buzzer for the problem of above-mentioned existence, and sounding is clear and melodious, and Stability Analysis of Structures is not fragile, and long service life.
Above-mentioned object realizes by following technical scheme:
Beating type electric magnetic buzzer, comprise tubular metal shell, the inside of described tubular metal shell is provided with the annular support of two axle center and tubular metal shell axis coinciding, wherein on the annular support of the axis part of close tubular metal shell, be provided with one group of electromagnetism iron plate, on each electromagnetism iron plate, there is conductive contact, on the annular support of the inwall of close tubular metal shell, hinged one group is hit iron hammer, the hammer stem middle part of described strike iron hammer is connected with the inwall of described tubular metal shell by spring, rotation power supply contact is installed in the axle center of described tubular metal shell.
Described beating type electric magnetic buzzer, described rotation power supply contact comprises rotation axis, described rotation axis inside is contact rod, described contact rod is wrapped with insulation course, contact rod connects a conductive contact, described conductive contact is through described insulation course, and described contact rod connects rotation drive motor and power supply.
Described beating type electric magnetic buzzer, the quantity of described electromagnetism iron plate and described strike iron hammer equate and installation site corresponding.
