Abstract
The utility model discloses a kind of rotary electromagnetic buzzers, are bonded in the upper end of rotating device by spring assembly including connecting plate and connecting plate；The rotating device is connected to the upper end of rotary shaft by rotary joint, and support base is set in rotary shaft；Cooling fin is set between the rotary shaft and main body, and rotary shaft is mutually welded with main body；Connecting bottom board is set between the main body and paster pin, and bottom plate is welded on main body lower end；The bottom plate is connected to the lower end of electromagnetic coil by iron core；The iron core upper end setting vibrating diaphragm；The principle of the utility model rotary electromagnetic buzzer is that the voice-frequency signalling current that oscillator generates passes through electromagnetic coil, electromagnetic coil is made to generate magnetic field, vibrating diaphragm is under the interaction of electromagnetic coil and magnet, periodically vibration sounding, vibrating diaphragm set by this buzzer is more clear the pronunciation of buzzer, and this buzzer is improved work efficiency, and improve stability using Rotation Design.
Description
Technical field
The utility model is related to a kind of buzzer more particularly to a kind of novel rotary electromagnetic buzzers.
Background technology
Domestic buzzer is a kind of electronics buzzer of integral structure at present, using DC-voltage supply, extensively should
For electronic products such as computer, printer, duplicator, alarm, electronic toy, vehicle electronics, telephone set, timers
In make microphone device, buzzer is broadly divided into piezo buzzer and electromagnetic buzzer two types, but in order to avoid because
What the voice effect of the buzzer caused by vibration was deteriorated happens, also for working efficiency and stability is improved, so setting
Count out a kind of rotary electromagnetic buzzer.
Invention content
（One）Technical problems to be solved
To solve the above problems, the utility model proposes a kind of rotary electromagnetic buzzers.
（Two）Technical solution
The utility model discloses a kind of rotary electromagnetic buzzers, pass through spring assembly including connecting plate and connecting plate
It is bonded in the upper end of rotating device；The rotating device is connected to the upper end of rotary shaft by rotary joint, and in rotary shaft
Support base is set；Cooling fin is set between the rotary shaft and main body, and rotary shaft is mutually welded with main body；The main body with
Connecting bottom board is set between paster pin, and bottom plate is welded on main body lower end；The bottom plate is connected to electromagnetic wire by iron core
The lower end of circle；The iron core upper end setting vibrating diaphragm.
Further, the rotary shaft is made of stainless steel.
Further, the vibrating diaphragm is in hollow frustroconical.
Further, the principle that the electromagnetic coil utilizes is electromagnetic induction principle.
Further, the main body periphery is equipped with metal case, and case is equipped with through-hole.
（Three）Advantageous effect
The principle of the utility model rotary electromagnetic buzzer is that the voice-frequency signalling current that oscillator generates passes through electromagnetic wire
Circle makes electromagnetic coil generate magnetic field, and vibrating diaphragm is under the interaction of electromagnetic coil and magnet, periodically vibration sounding,
Vibrating diaphragm set by this buzzer is more clear the pronunciation of buzzer, and this buzzer is carried using Rotation Design
High working efficiency, and improve stability.
