Abstract
The invention relates to a buzzer. The buzzer comprises a buzzer casing, a double-side piezoelectric disc and a film material, wherein the film material is directly bonded on the buzzer casing, and the double-side piezoelectric disc is bonded on the film material. According to the buzzer, the sound pressure level is improved, and the small dimension property is further kept so that the buzzer can further be applied to portable products.
Description
Technical field
The present invention relates to gas detection product. Specifically, the present invention relates to the modified node method of a kind of hummer and use the gas detector of this hummer.
Background technology
Piezoelectric buzzing device is extensive a kind of sounding alarm device for household electrical appliance. Piezoelectric buzzing device is pasted on piezoelectric ceramic piece after high voltage polarization to vibrate on tinsel, after adding voltage of alternating current, because of piezoelectric effect, can produce mechanical deformation and stretches and shrink, utilize this kind of characteristic that vibration tinsel is vibrated and sounding. Vibration tinsel is arranged at enclosure interior, and shell end is provided with a hole, and the sound that vibration tinsel is sent can be spread out of by hole, to allow the ear of people hear the sound.
As shown in the vertical view in Fig. 1, the top of the hummer housing 11 of prior art is provided with a sound holes 13. Piezoceramic disk 15 is attached on the piezoelectricity disc mounting part of hummer housing 11. Hummer housing 11 and piezoceramic disk 15 surround resonant chamber, and spread out of to allow people hear by sound by sound holes 13. In order to install piezoceramic disk 15 and surround resonant chamber together with piezoceramic disk 15, hummer housing 11 must have certain axial length. In order to change the sound pressure level of hummer, the size of hummer housing 11 and piezoceramic disk 15 just must be changed. Owing to piezoelectricity disc mounting part must be formed on hummer housing 11, which results in the complexity of manufacturing process and cost increase.
JPS5992699A discloses a kind of hummer structure. See Fig. 1,2, piezoceramic disk 1 is arranged on the piezoelectricity disc mounting part 3 of housing 2. Lead-in wire 8-10 is connected to piezoceramic disk 1. When being energized, piezoceramic disk 1 is out of shape and vibrates, the sounding by the resonant chamber of housing 2, piezoelectricity disc mounting part 3 and piezoceramic disk 1 formation.
Existing buzzer sound is forced down. Although existing various effort improves the acoustic pressure of hummer, but these effort increase the size of hummer all more or less. Therefore, this area exists demand: the sound pressure level that hummer should be improved always, make the size of hummer enough little of to be applicable to portable product again.
Summary of the invention
By proposing, a kind of novel hummer structure solves in this area the problems referred to above existed at present in the present invention.
Hummer according to the present invention, comprises hummer housing, it is characterised in that, described hummer also comprises two side pressure electroplax and mould material, and described mould material is directly bonded on described hummer housing, and described pair of side pressure electroplax is bonded on described mould material.
Preferably, described mould material is polyester film.
Preferably, described mould material has coniform shape, and described pair of side pressure electroplax is bonded to the top of coniform shape.
Preferably, described mould material utilizes epoxy bond to arrive described hummer housing.
Preferably, the top of described hummer housing is provided with multiple sound holes.
A kind of gas detector, it is characterised in that, described gas detector uses any one hummer above.
Accompanying drawing explanation
By referring to embodiment and claim, and considering by reference to the accompanying drawings, can obtaining the more fully understanding to this theme, Reference numeral identical in the drawings and in which represents similar element. In accompanying drawing:
Fig. 1 is vertical view and the sectional view of the hummer that prior art is described;
Fig. 2 is vertical view and sectional view that hummer according to one embodiment of present invention is described.
Embodiment
Specific descriptions below are only exemplary in essence, are not application and the use of the embodiment or these embodiments for limiting this theme. When using herein, word " exemplary " expression " as example, example or explanation ". It is preferred or favourable that any exemplary enforcement mode described herein all not necessarily is understood to compare other enforcement mode. And, it is not intended to the constraint by any theory expressed or imply occurred in the technical field above, background technology, summary of the invention or embodiment below.
Referring now to Fig. 2, it illustrates the structure of hummer according to one embodiment of present invention. This hummer comprises hummer housing 21, mould material 27, two side pressure electroplax 25. Mould material 27 adopts suitable caking agent to be directly bonded on hummer housing 21. Preferably, bond with epoxy resin. Re-use suitable caking agent to be bonded on mould material 27 by two side pressure electroplax 25. Mould material 27 is polyester film preferably. In the indefiniteness embodiment shown in Fig. 2, mould material 27 has coniform shape, and two side pressure electroplax 25 is bonded in the top place of the cone of mould material 27. It is to be understood that mould material 27 can have other shape of any appropriate.
During energising, different from the hummer of prior art, the vibration of two side pressure electroplax 25 is propagated by mould material 27, thus considerably improves sound pressure level. In an exemplary embodiment, sound pressure level improves 5-8dB than the sound pressure level (95dB30cm) of the hummer of prior art. Meanwhile, the size of hummer according to embodiments of the present invention is not extended. On the contrary, compared with the sealer in Fig. 1, also less according to the hummer of the present invention size in the axial direction. Thus so that applicable in portable product according to the hummer of the present invention. Meet current certificate requirements. Meanwhile, owing to not needing to be formed piezoelectricity disc mounting part on hummer housing 21, thus simplify the manufacture of hummer housing 21, save manufacturing cost.
Preferably, the top of hummer housing 21 is provided with multiple sound holes 23. These sound holes 23 to be met the requirement of the sound pressure level becoming high, can provide mechanical protection for hummer again simultaneously.
Although specific descriptions above giving at least one exemplary embodiment, but it should recognize and there is a large amount of modification. It also should be appreciated that one or more exemplary embodiment described herein never is used to limit scope, the applicability of claimed theme or constructs. More properly say, the route map easily specifically described being provided for the one or more exemplary embodiment described by enforcement to those skilled in the art above. It is to be understood that when not departing from the scope being defined by the claims, the function of element and layout can be carried out various change, this is included in known equivalent way and foreseeable equivalent way when submitting present patent application to.
