Piezoelectric speaker of the present utility model, antenna traces is set on piezoelectric patches surface, antenna assembly and piezoelectric speaker are wholely set, realize loudspeaker function and antenna function simultaneously, do not increase piezoelectric speaker thickness, be conducive to slimming design and the Integration Design of product.
Accompanying drawing explanation
Fig. 1 is the utility model piezoelectric speaker exploded view;
Fig. 2 is for piezoelectric speaker piezoelectric patches and wiring board described in Fig. 1 are in conjunction with schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, describe the utility model content in detail:
As shown in Figures 1 and 2, the utility model piezoelectric speaker, comprises framework, the vibrating diaphragm 2 fixed with framework and the piezoelectric patches 3 with vibrating diaphragm 2 secure bond, and framework comprises protecgulum 11 and back cover 12, and vibrating diaphragm 2 collecting is fixed between protecgulum 11 and back cover 12.The utility model piezoelectric speaker also comprises conducting terminal 5, and piezoelectric patches 3 is electrically connected with conducting terminal 5.Piezoelectric patches 3 and external circuit are electrically coupled by conducting terminal 5, and external drive signal enters into piezoelectric patches 3 by conducting terminal 5, and piezoelectric patches 3 produces inverse piezoelectric effect and vibrates, and drive vibrating diaphragm 2 to vibrate, and air sounding is instigated in vibrating diaphragm 2 vibration.
As shown in Figure 2, piezoelectric patches 3 surface of the utility model piezoelectric speaker is provided with antenna traces 6, and antenna traces 6 is also electrically connected with conducting terminal 5.Be arranged at the antenna traces 6 on piezoelectric patches 3 surface, make the utility model piezoelectric speaker be integrated with antenna function, be not provided with other metal materials in piezoelectric speaker and without magnetic interference, antenna traces 6 favorable working performance.Further, be arranged at the antenna traces 6 on piezoelectric patches 3 surface, additionally do not take up room, do not increase the space of piezoelectric speaker, be conducive to the slimming design of product, therefore, the utility model piezoelectric speaker has slimming and designs, the advantage that integrated level is high.
As shown in Figure 2, on conducting terminal 5, corresponding piezoelectric patches 3 is provided with the first pad 51, respective antenna circuit 6 is provided with the second pad 52, piezoelectric patches 3 and antenna traces 6 are respectively by independently pad and conducting terminal 5 are electrically coupled, be electrically connected with external circuit respectively by conducting terminal 5 again, therefore, piezoelectric patches 3 and antenna traces 6 can separate work.
Preferred as one, antenna traces 6 is conductive metal lines, in actual applications, the materials such as silver, copper or electrical conductivity alloy can be adopted as antenna traces.Can pass through LDS (laser direct forming) is arranged on piezoelectric patches 3 by antenna traces 6, also can adopt other modes, all not affect the utility model piezoelectric speaker advantage applies.
As shown in Figure 1, the piezoelectric speaker of the present embodiment, protecgulum 11 is provided with the phonate hole for sound outgoing.
As shown in Figure 1, be provided with gasket ring 4 between piezoelectric patches 3 and vibrating diaphragm 2, piezoelectric patches 3 is connected and fixed by gasket ring 4 and vibrating diaphragm 2, and gasket ring 4 can improve the consistency that vibrating diaphragm 2 vibrates, and improves piezoelectric speaker acoustical behavior.As a kind of preferred version, gasket ring 4 can be PEN material.
In actual applications, vibrating diaphragm 2 can adopt macromolecular material vibrating diaphragm.Conducting terminal can be flexible circuit board.All can embody the utility model piezoelectric speaker advantage.
These are only the utility model case study on implementation, be not limited to the utility model, as long as those of ordinary skill in the art modify or change according to the equivalence that the utility model institute disclosure is done, all should include in the protection range recorded in claims.
