Technical Field
[0001] The utility model relates to the technical field of intercoms, in particular to a miniature intercom for outdoor use. Background Art
[0002] A walkie-talkie is a portable device for wireless communication that allows users to conduct two-way voice communication within a relatively short distance. First of all, walkie-talkies support group call functions, which can communicate with multiple people at the same time, facilitating team collaboration and collective communication. In addition, walkie-talkies are portable and lightweight, easy to carry, and users can carry them with them and communicate at any time. Walkie-talkies do not rely on Internet connections or mobile phone signals, and can be used without network connections. They are suitable for environments without network coverage or imperfect communication infrastructure. Finally, walkie-talkies usually have a rugged design that can withstand large impacts and harsh environments, and are suitable for use in harsh conditions such as outdoor and industrial use. In summary, walkie-talkies have obvious advantages in immediacy, group calls, portability, independent communication, and durability, making them widely used in many industries and scenarios.
[0003] At present, the walkie-talkies on the market are large in size, poor in drop resistance, and are all rectangular in shape.
