Description
Technical field
The present invention relates to buzzer device field, and in particular to a kind of adjustable buzzer of intensity of acoustic wave.
Background technology
Buzzer is a kind of electronics buzzer of integral structure, using DC-voltage supply, be widely used in computer,
Make acoustical generator in the electronic products such as printer, duplicator, alarm, electronic toy, vehicle electronics, telephone set, timer
Part.Buzzer is broadly divided into piezo buzzer and electromagnetic buzzer two types.Current buzzer adjusts intensity of acoustic wave
Difficulty, it is inconvenient for use.
The content of the invention
The purpose of the present invention is that to solve the above-mentioned problems and provides a kind of intensity of acoustic wave adjustable buzzer.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of adjustable buzzer of intensity of acoustic wave, including pin, vibrating membrane, damping sheet, adjusting nut, the pin pass through
Shell, the adjusting nut above the shell adjust briquetting by screw, the damping sheet are provided with below the briquetting,
Both sides press closer the vibrating membrane below the damping sheet, and magnet is provided with below the vibrating membrane, is set among the magnet
There is coil, the coil is wrapped on iron core, and the magnet is installed on bottom plate, and circuit board is provided with below the bottom plate.
During buzzer use, by the adjusting nut screw can be made to be pressed downward the briquetting,
The briquetting reduces the vibration vibration of membrane to applying pressure among the damping sheet, and using the side of the damping sheet
Frequency, so that change the intensity of sound that the vibrating membrane is sent, it is easy to adjust.
In order to further improve its using effect, the pin and the welding circuit board, the circuit board pass through screw
It is fixed on the bottom plate lower part.
In order to further improve its using effect, the magnet is fixedly connected by screw with the bottom plate top, described
Iron core is arranged on the shell centre position.
In order to further improve its using effect, the briquetting press against the damping sheet centre position, the damping sheet two
Side pressure the vibrating membrane.
Beneficial effect is：The buzzer is simple in structure easy to adjust the intensity of sound wave, easy to use.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of adjustable buzzer of intensity of acoustic wave, including pin 1, vibrating membrane 6, damping sheet 11, adjusting spiral shell
Mother 8, pin 1 pass through shell 7, and pin 1 is used for coil 4 and connects power supply, and the adjusting nut 8 of the top of shell 7 is adjusted by screw 9 presses
Block 10, screw 9 can be pressed by screw thread to 10 centre position of briquetting, and 10 power transmission of briquetting passes through damping sheet 11 to damping sheet 11
The frequency of vibrating membrane 6 is adjusted, the lower section of briquetting 10 is provided with damping sheet 11, and 11 lower section both sides of damping sheet press closer vibrating membrane 6, vibration
The vibration of film 6 can beep, and the lower section of vibrating membrane 6 is provided with magnet 5, coil 4 is provided among magnet 5, coil 4 is wrapped in
On iron core 12, magnet 5 is installed on bottom plate 3, and the lower section of bottom plate 3 is provided with circuit board 2.
During buzzer use, by adjusting nut 8 screw 9 can be made to be pressed downward briquetting 10, briquetting 10 is right
Apply pressure, and the vibration frequency of the side reduction vibrating membrane 6 using damping sheet 11 among damping sheet 11, so as to change vibration
The intensity of sound that film 6 is sent, it is easy to adjust.
In order to further improve its using effect, pin 1 is welded with circuit board 2, and circuit board 2 is fixed on bottom by screw 9
3 lower part of plate, magnet 5 are fixedly connected by screw 9 with 3 top of bottom plate, and iron core 12 is arranged on 7 centre position of shell, and briquetting 10 is pressed
11 centre position of damping sheet, 11 both ends of damping sheet press against vibrating membrane 6.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe the original of the present invention
Reason, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appending claims and equivalents circle
It is fixed.
