The utility model discloses adjustable buzzers, it is characterized by: having shell, iron core is fixed in the interior of shell, electromagnetic coil is coated on the outside of the iron core, limited block is equipped in the top of the iron core, the top of the limited block and rotation axis connection, the rotation axis and the screw top of shell connect, and its top is pierced by the shell outward, armature is equipped between the iron core and limited block, the inside of the shell is hingedly arranged in the armature, and one end of the armature is connect with elastic component.The utility model structure is simple, and design rationally, and can be conveniently adjusted the volume of buzzer according to use demand.
Description
Technical field
The utility model relates to safe audible devices, and in particular to a kind of adjustable buzzer.
Background technique
Buzzer is a kind of electronics buzzer of integral structure, is widely used in computer, printer, duplicator, report
Make microphone device in the electronic products such as alert device, electronic toy, vehicle electronics, telephone set, timer.Currently, buzzer master
It to include piezoelectric type and two kinds of electromagnetic type, wherein electromagnetic buzzer mainly includes electromagnetic coil, magnet and vibrating diaphragm etc., electricity
Magnetic coil generates magnetic field after powered up, and vibrating diaphragm is under the interaction of electromagnetic coil and magnet, and periodically vibration issues
The sound.Above structure has the disadvantage that the volume of the generation of buzzer is often that can not adjust, and can no longer meet user
Use demand, and the adjustable buzzer of volume is adjusted using complicated circuit system on the market, this
It allows for buzzer and also needs to be equipped with complicated control route, and it occur frequently that control route during prolonged use
The case where damage, causes the practicality poor.
Summary of the invention
In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide a kind of structure is simple, if
Meter rationally, can be conveniently adjusted the adjustable buzzer of volume according to use demand.
For this purpose, the utility model is realized using following scheme:
Adjustable buzzer, it is characterised in that: there is shell, iron core is fixed in the interior of shell, in the iron
It is coated with electromagnetic coil on the outside of core, is equipped with limited block in the top of the iron core, the top of the limited block and rotation axis connect
It connects, the screw top connection of the rotation axis and shell, and its top is pierced by the shell outward, in the iron core and limited block
Between be equipped with armature, the inside of the shell is hingedly arranged in the armature, and one end of the armature is connect with elastic component.
The elastic component is spring.
The limited block is an integral molding structure with the rotation axis.
By adopting the above technical scheme, the advantages of the utility model are as follows: 1, structure it is simple, design rationally, can be realized scale
Metaplasia produces；2, after electromagnetic coil is powered, iron core is magnetized and generates magnetism and attract the armature bottom and hit iron core, sending sound
It rings, and after electromagnetic coil power-off, the magnetic of iron core disappears, and armature separates under the action of the elastic member with iron core and and limited block
It offsets, electromagnetic coil alternately power on/off can constantly hit iron core to issue the sound, in addition, passing through with moving armature
Adjusting rotation axis drives limited block to be gone up and down, i.e., the amplitude that adjustable armature is swung, and then realizes the adjusting of buzzer volume.
Detailed description of the invention
The utility model has following attached drawing
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown, adjustable buzzer disclosed by the utility model, has shell 6, is fixed with iron inside shell 6
Core 4 is coated with electromagnetic coil 5 in the outside of iron core 4, is equipped with limited block 2, the top of limited block 2 and rotation in the top of iron core 4
Axis 1 connects, and limited block 2 is an integral molding structure with rotation axis 1 in the present embodiment, so that the structure of the present apparatus is more compact, group
It fills more convenient.Rotation axis 1 is connect with the screw top of shell 6, and its top is pierced by shell 6 outward, in iron core 4 and limited block
Armature 3 is equipped between 2, armature 3 is hingedly arranged on the hinged seat 9 inside shell 6, and one end of armature 3 is connect with elastic component 8,
One end of elastic component 8 is fixedly connected on the attachment base 7 inside shell 6, and the elastic component 8 in the present embodiment is spring.
After electromagnetic coil 5 is powered, iron core 4 is magnetized and generates magnetism and attract 3 bottom of armature and hit iron core 4 concurrently
The sound out, and after electromagnetic coil 5 powers off, the magnetic of iron core 4 disappears, and armature 3 separates simultaneously under the action of elastic component 8 with iron core
It offsets with limited block 2, the alternately power on/off (or use alternating current) of electromagnetic coil 5 can constantly be hit with moving armature 3
Iron core 4 is to issue the sound, in addition, drive limited block 2 to be gone up and down by adjusting rotation axis 1, i.e., what adjustable armature 3 was swung
Amplitude, and then realize the adjusting of buzzer volume.
