Description

Technical Field

[0001] The utility model relates to the technical field of microphones, in particular to a dual-power supply head-mounted microphone. Background Art

[0002] With the development of society, head-worn microphones have been widely welcomed by people due to their small size and convenience of use. In particular, invisible head-worn microphones can achieve a nearly invisible effect due to their extremely small structure.

[0003] A Chinese patent with publication number CN220401919U was searched and disclosed a head-worn microphone, which includes: a fixed clamp ring, which is a C-shaped ring structure with elasticity and is used for clamping and fixing; a microphone assembly, which is arranged at one end of the fixed clamp ring; and an elastic assembly, both ends of which are connected to the fixed clamp ring, and the elastic assembly is always in a stretched state, and the elastic assembly cooperates with the fixed clamp ring to form a bow structure. The elastic assembly includes an elastic member and connecting members respectively arranged at both ends of the elastic member, and the elastic member is connected to the fixed clamp ring through the connecting members at both ends, and the elastic member is always in a stretched state.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] When the existing microphone runs out of power, most staff members directly replace the microphone. Replacing the microphone will cause a lot of time waste, which is not conducive to the long-term use of the microphone, and further reduces the use efficiency of the microphone.

[0006] In order to solve the above technical problems, the utility model proposes a dual-power supply head-mounted microphone, which drives the bar block on the fixed column to move the fixed rod on the first U-shaped block in the movable hole, drives the second U-shaped block on the connecting column to swing, and drives the roller on the connecting rod to move from one side of the movable cavity to the other side.

[0007] The technical solution to achieve the purpose of the utility model is: a dual-power headset microphone, including a fixed block, one side of the fixed block is fixedly connected to a shell, one side inner wall of the shell is fixedly connected to a fixed column, a strip block is rotatably sleeved on the circumferential outer wall of the fixed column, one end of the strip block is fixedly connected to a first U-shaped block, and also includes;

[0008] an adjusting mechanism, wherein the adjusting mechanism is located on the housing;

[0009] The adjustment mechanism includes an active cavity opened on the outer shell, a roller is fitted in the active cavity, a fixed rod is fixedly connected to the first U-shaped blocks on one side close to each other, a connecting column is slidably sleeved on the circumferential outer wall of the fixed rod, a movable hole is opened on the connecting column, the movable hole is adapted to the fixed rod, a second U-shaped block is fixedly connected to one end of the connecting column, a connecting rod is fixedly connected to the second U-shaped block on one end of the second U-shaped blocks, a connecting rod is fixedly connected to the second U-shaped block on one side close to each other, a roller is rotatably sleeved on the circumferential outer wall of the connecting rod, a reset spring is sleeved on the connecting column, and both ends of the reset spring are respectively fixedly connected to the second U-shaped block and the fixed rod.

[0010] In some embodiments, two limiting columns are fixedly connected to an inner wall of one side of the shell, and two bar blocks are located in the middle of the limiting columns.

[0011] In some embodiments, two touch sensors are installed in the active cavity.

[0012] In some embodiments, a toggle button is mounted on one side of the housing.

[0013] In some embodiments, an indicator light is installed on one side of the housing.

[0014] In some embodiments, a pipe clamp is installed on the fixing block, and a hanging ear assembly is installed on the pipe clamp.

[0015] In some embodiments, a sound pickup assembly is mounted on the fixing block.

[0016] Compared with the prior art, the present invention has the following significant advantages:

[0017] The utility model is worn through the ear hanging assembly on the pipe clamp, and the sound is transmitted through the sound pickup assembly. When the microphone has no sound, the bar block on the fixing column can be toggled to drive the fixing rod on the first U-shaped block to move in the movable hole, drive the second U-shaped block on the connecting column to swing, drive the roller on the connecting rod to move from one side of the movable cavity to the other side, and touch the touch sensor on the way to the other side. The range of movement of the bar block is limited by the limit column, and the power supply on the other side of the dual power supply is turned on, which is convenient for turning on the sound of the microphone, realizing the power supply conversion of the microphone, avoiding the use of the microphone when replacing, and improving the working efficiency of the microphone when in use.

[0018] The invention solves the problem that when the existing microphone runs out of power, most of the staff directly replace the microphone, which wastes a lot of time and is not conducive to the long-term use of the microphone, thereby reducing the use efficiency of the microphone.
