[0002] In modern medicine, industrial protection, and public safety, respirators are widely used as essential personal protective equipment to protect against harmful gases, dust, and viruses. However, the structure and materials of the respirator often hinder speech transmission, leading to unclear speech and affecting normal communication. This problem is particularly prominent in scenarios with high communication efficiency requirements, such as medical emergency response, fire rescue, and factory operations. Traditional solutions often use external microphones or handheld walkie-talkies for voice acquisition and transmission, but these methods have many shortcomings: for example, external microphones are easily affected by environmental noise, resulting in unstable voice quality; handheld devices reduce the convenience and safety of operation. Furthermore, while some existing products integrate Bluetooth communication modules, they still have significant shortcomings in power consumption control, voice clarity, and wearing comfort, making it difficult to meet the needs of prolonged wear and use in complex environments.
[0003] To address these issues, we provide a Bluetooth microphone for use within a breathing mask. Utility Model Content

[0031] Furthermore, an elastic buckle 101 is provided at the middle position of the top side of the main body 100, and a switch button 102 is embedded at the middle position of the top of the main body 100. The main body 100 has a U-shaped structure, and the top of the main body 100 is detachably connected to the breathing mask through the elastic buckle 101.
[0032] The Bluetooth microphone for use in a breathing mask provided in this embodiment has a compact overall structure and high functional integration, making it suitable for clear voice acquisition and wireless transmission when wearing a mask. The device mainly includes a U-shaped main body 100, with a microphone 200 and a control unit 300 respectively located at its lower ends. These two units are electrically connected to the main body 100 via a plug-in connection, facilitating installation and maintenance.
