Description

wireless transmitter

The present invention relates to a microphone, in particular to a wireless transmitter for wirelessly transmitting sound signals.

In many large-scale concerts, in order to make both hands free to perform to the fullest, performers usually wear a headband headset and install a wireless transmitter connected to the headband headset signal on their body. This type of wireless transmitter generally includes a housing containing a battery, a battery cover installed in the housing to cover the battery compartment, and a battery cover arranged in the housing and used to connect with the headband. The circuit board where the headset signal is connected. Currently, the battery cover of the wireless transmitter usually adopts a flip-type design or a slide-type design. Although it can be easily opened to replace the battery, the waterproof performance is poor.

Since this type of wireless transmitter is installed close to the body, once the performer sweats a lot, sweat and moisture can easily penetrate into the interior through the gap between the battery cover and the casing.
