Description

Technical Field

[0001] This utility model relates to the field of walkie-talkie technology, specifically a walkie-talkie with a horn and a spring contact. Background Technology

[0002] Walkie-talkies can communicate without any network support and incur no call charges. They are suitable for relatively fixed and frequent communication situations. They consist of a casing, main unit, battery, belt clip, charger, and antenna. There are three main types of walkie-talkies: analog walkie-talkies, digital walkie-talkies, and IP walkie-talkies.

[0003] Walkie-talkies are terminal devices for trunked radio communication. They can be used not only as terminal devices for trunked radio communication, but also as a professional wireless communication tool in mobile communication. The communication function of walkie-talkies is realized through a receiver unit and a speaker unit. The speaker unit is the horn. Currently, the horn of walkie-talkies is often connected to the circuit board by soldered wires. After long-term use, the solder joints may come off, making the walkie-talkie unusable, which is quite inconvenient. Utility Model Content

[0006] The upper housing is detachably mounted on the top of the lower housing, and a circuit board is provided at the bottom of the upper housing. The tops of the two metal springs are respectively tightly attached to the two metal contacts of the circuit board.

[0007] Furthermore, both of the aforementioned metal springs are made of copper and are integrally formed.

[0008] Furthermore, a control unit is integrated on the upper surface of the circuit board, and a push button corresponding to the control unit is provided on one side surface of the lower housing.

[0009] Furthermore, anti-slip textures are provided on the rear parts of both sides of the lower housing.

[0010] Furthermore, the rear part of the upper surface of the upper housing is recessed to form a battery mounting groove.

[0011] Furthermore, both the upper housing and the lower housing are made of plastic.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the walkie-talkie with a speaker and spring contact, by setting metal springs, the speaker body and the circuit board in the device are connected by two metal springs. The metal springs are made of copper and are integrally formed. They are elastic and can always fit in contact with the contact surface of the circuit board, so there will be no problem of open circuit. In addition, copper itself has relatively stable chemical properties and is not easy to corrode, thereby improving the service life of the walkie-talkie. Attached Figure Description
