Description

Technical Field

[0001] This utility model relates to the field of fire protection, specifically to a novel mask-style headphone connection structure. Background Technology

[0002] A face mask headset is a voice receiving and transmitting device that is mounted or connected to a face mask. It connects to a walkie-talkie via an intermediate converter such as a PTT (Push-to-Talk) system, serving as a voice communication device between firefighters. This provides firefighters with a means of receiving external instructions and relaying feedback from the scene to outside personnel in emergency situations.

[0003] Conventional face-mounted headphones are either integrated with the face mask or mounted to the face mask via an intermediate connector. The first type, the integrated face mask design, makes cleaning, maintenance, and upkeep of the face mask inconvenient; the second type, due to the use of an intermediate connector, increases installation complexity, and the increased number of parts leads to higher costs, lower product stability, and reduced reliability.

[0004] Conventional mask-style headsets use an air conduction solution for communication, which makes call quality susceptible to interference from the external environment. This is not conducive to voice communication in high-noise environments and reduces call quality.

[0005] Therefore, a new type of mask-style headphone connection structure is needed. Utility Model Content

[0006] This utility model discloses a novel mask-style headphone connection structure. The mask-style headphone and mask are installed onto the face shield frame via a slot. After installation, the bone conduction microphone fits tightly against the face shield. The bone conduction microphone uses the vibration of the face shield to perform voice recognition and transmit voice information to external personnel. The bone conduction speaker fits against the user's cheek and receives voice information from the outside through bone conduction vibration. The length and angle adjustment levels can be adjusted to suit the different face shapes and sizes of users.

[0007] This utility model is achieved through the following technical solution:

[0008] A novel mask-style headphone connection structure includes a mask with a face shield frame. A mask-style headphone is snapped onto the face shield frame. The mask-style headphone includes a snap-fit ​​part and an adjustment part. The snap-fit ​​part has a slot that matches the side frame of the face shield frame. A bone conduction microphone is located on the side of the slot. A bone conduction speaker is installed on the adjustment part. When the mask-style headphone is snapped onto the face shield frame, the bone conduction microphone is tightly fitted to the face shield.

[0009] Furthermore, the adjustment part includes a first connector and a second connector. One end of the first connector is fixedly connected to the snap-fit ​​part, and the other end is hinged to fix the second connector. The bone conduction horn is fixedly connected to the second connector.

[0010] Furthermore, the hinge of the second connector is provided with a plurality of arc-shaped grooves, and the hinge of the first connector is provided with a positioning protrusion. The connection angle between the first connector and the second connector can be adjusted by adjusting the position of the positioning protrusion inserted into the groove.

[0011] Furthermore, the second connector is provided with a strip-shaped hole, and the bone conduction horn is locked and fixed to the second connector by a screw passing through the strip-shaped hole.

[0012] Furthermore, the inner side of the strip hole is wavy, and an avoidance groove is provided on the outer side of the strip hole.

[0013] The beneficial effects of this utility model are as follows:

[0014] The headset is easy and convenient to install and remove, requiring no tools. This ease of installation and removal greatly facilitates the cleaning, maintenance, and upkeep of the face mask. Secondly, the elimination of intermediate connectors reduces costs and increases product reliability. Thirdly, the communication system utilizes a full bone conduction solution; both voice reception and transmission employ advanced bone conduction technology, ensuring clear communication unaffected by external environmental factors, improving overall call quality, enhancing the firefighter's experience, and providing an additional layer of safety.
