Abstract
The utility model discloses a novel piezoelectric buzzer which comprises a hollow shell, a vibrating metal piece and a circuit board, wherein the end of the shell is provided with a circular through hole; a piezoelectric ceramic chip is jointed in the center of the lower end surface of the vibrating metal piece; the circuit board is arranged in the shell; the novel piezoelectric buzzer is characterized in that the shell is internally provided with a groove, and the vibrating metal piece is arranged in the groove; a cavity arranged at the upper part of the shell is internally provided with a truncated cone-shaped vibration diaphragm; the lower end surface of the truncated cone-shaped vibration diaphragm is spliced on the upper end surface of the vibrating metal piece; and the upper end surface of the truncated cone-shaped vibration diaphragm is closely connected with the shell, so that a closed structure can be formed. The novel piezoelectric buzzer is provided with the truncated cone-shaped vibration diaphragm made of polypropylene material in the shell, thus not only obtaining the high-quality tone and the desired frequency characteristic, but also having good waterproof and dustproof performances.
Description
Technical field
The utility model relates to a kind of hummer, is specifically related to a kind of novel piezoelectric formula hummer with the high-quality sound and tool water resistance.
Background technology
Piezoelectric buzzer is that piezoelectric ceramic piece behind the high voltage polarization is pasted on the vibration sheet metal, after adding alternating voltage, and can be because of piezoelectric effect; Produce mechanically deform and stretch and shrink, utilize this characteristic to make and vibrate the sheet metal vibration and send the sound, the vibration sheet metal is arranged at enclosure interior; And be provided with a hole in shell end, the sound that the vibration sheet metal is sent can be spread out of by the place, hole, so that people's ear can be heard the sound; But, when said structure uses in reality, but have following shortcoming:
1, because shell end is provided with the hole, it is inner to make water or dust get into hummer by the place, hole easily, inner when water entering hummer, then is easy to make the vibration sheet metal to get rusty, and also causes the damage of hummer easily.
2, general hummer does not have the sound film, and during use, loudness is low, acoustic pressure is unstable, during temperature variation, causes sound attenuating easily.
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The utility model content
The technical matters that the utility model will solve is: the deficiency that is directed to prior art; A kind of novel piezoelectric formula hummer is provided; This novel piezoelectric formula hummer is the truncated cone-shaped vibrating membrane that material is processed through in housing, establishing one with the polypropylene; Not only can make hummer obtain high-quality tone color and desirable frequency characteristic, and have the performance of fabulous waterproof and dustproof.
For reaching the foregoing invention purpose, the technical scheme that the utility model adopted is: a kind of novel piezoelectric formula hummer comprises: a hollow housing, shell end have a manhole; One vibration sheet metal, vibration sheet metal lower surface centre engages a piezoelectric ceramic piece; One circuit board is arranged at enclosure interior, and the circuit board place is provided with one respectively and is connected the lead and of vibration on the sheet metal and is connected the lead on the piezoelectric ceramic piece; Housing is outside equipped with first lead-in wire and second lead-in wire; Said first lead-in wire be connected the lead that vibrates on the sheet metal and be connected; Said second lead-in wire is connected with lead on being connected piezoelectric ceramic piece, it is characterized in that: a groove is set in the housing, vibrates sheet metal and be positioned in the groove; One truncated cone-shaped vibrating membrane is installed in the housing upper cavity, and the lower surface of said truncated cone-shaped vibrating membrane is bonded on the vibration sheet metal upper surface, and the upper surface of truncated cone-shaped vibrating membrane and housing closely connect into closed structure.Preferably, the material of said truncated cone-shaped vibrating membrane is an acrylic plastering.
In sum, the novel piezoelectric formula hummer that the utility model provided has the following advantages:
1, the utility model is provided with groove in housing, and the vibration sheet metal is fixed in the groove, avoids adopting the frame mode of glue fixing, thereby simplifies production technology.
2, this novel piezoelectric formula hummer is the truncated cone-shaped vibrating membrane that material is processed through in housing, being provided with one with the polypropylene, not only can make hummer obtain high-quality tone color and desirable frequency characteristic, and have the performance of fabulous waterproof and dustproof.
