What are the main components of the walkie-talkie?

Shell

Professional machine generally uses a very good performance of plastic material PC + ABS, the appearance of good gloss, not easy to aging, wear, durable products; commercial aircraft often use engineering plastic ABS, in the appearance, strength, wear resistance, aging and other aspects can Good to meet the requirements; button using silicone, wear-resistant, not aging, feel good; aluminum shell lightweight material aluminum alloy ADC12, easy molding and follow-up processing.

Hosts

General include face case, PTT button, earphone and power jack

Intercom charger

Plugs, PCB components, LCD parts, volume/switch knobs, coding knobs, indicator lights,

MIC and so on. The PTT button acts as a launch switch, typically on the side. The indicator light indicates the working status, generally at the top. On the top of the intercom, there is also a volume/switch button and an encoder knob (select channel). The LCD section visually shows the working status of the intercom. The PCB assembly is the core part of the intercom and is important

The device is on the PCB and non-professionals are not allowed to disassemble. Most walkie-talkies have special shielding covers and aluminum shells (fixed PCBs) because of their technical performance and resistance to drop. Professional machines also have waterproof requirements and the structure is more complicated.

Battery

The battery is divided into Ni-Cd, Ni-MH battery and Li-ion battery, capacity 600mAh, 900mAh, 1100mAh, 1300mAh, 1500mAh, 1700mAh, 1800mAh, 2000mAh, 2200mAh, 2400mAh. Lithium batteries are more expensive and still in development. Ni-Cd and Ni-MH batteries are commonly used, and Ni-MH batteries are generally recommended for large-capacity batteries. Battery surface and bottom shell are welded ultrasonically, which is solid and reliable.

Belt clip

The function is to fix the interphone on the belt. For the convenience of the customer, the belt clip can be disassembled. antenna

Divided into two parts: antenna jacket and antenna core. Antenna jacket with high-performance TPU material, good bending resistance and aging resistance; antenna core is generally connected with the host thread structure, easy removal.

Charger

Charge the battery or the whole unit with the bull. The structure generally has DC sockets, charging shrapnel, indicator lights, buttons and so on. The DC socket is connected with the fire cow. The shrapnel is connected with the battery pole piece. The indicator light indicates the charging status, and the button is used for discharging. The charger can generally charge the battery and the whole machine.

In addition

The walkie-talkie also has leather accessories, earphones, microphones, waterproof covers and other ancillary products.
