Positioning finder

[0036] Example 1:

[0037] like Figure 1-8 As shown, a positioning finder comprising a housing 1, and an inner portion of the housing 1 is provided at the first total rumor A, located below the second residential cavity B and for the first The resonance chamber A and the second covarian B are separated and used in the buzzer 2, the positioning finder further includes a main board 3 for controlling the buzzer 2 in which the buzzer 2 is connected. And a power supply device for powering with the motherboard 3 is connected to the motherboard 3.

[0038] The positioning finder uses the buzzer 2 to vote, compared to the sound elements such as the buzzer or speaker, the buzzer 2 has a small power consumption, longer use, and the use of the button battery can be met. The buzzer 2 is mainly composed of a piezoelectric ceramic plate and a metal plate brass or stainless steel. When the adhesive is used, the piezoelectric vibrating plate and the metal sheet are bonded together, and when the DC v

[0055] Example 2:

[0056] like Figure 9 As shown, the difference from the embodiment is connected between the main board 3 and the buzzer 2 through the elastic folded pin 7. The connection between the main board 3 and the buzzer 2 is performed using the elastic folded foot 7, and the overall structure of the positioning lookup can be thinner than the connection of the thimble 6.
