Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a clip-on Bluetooth headset with dynamic clamping force reminder function. Background Technology

[0002] As a wearable smart device, clip-on Bluetooth headphones are widely used in sports, office and other scenarios due to their advantages such as comfortable wearing and no obstruction of environmental perception.

[0003] Existing technologies mainly achieve call reminders through vibration motors or sound alerts (earphone charging cases). However, these technologies have the following drawbacks: 1. Vibration reminder limitations: The built-in vibration motor vibrates continuously during incoming calls, requiring additional power, increasing power consumption, and shortening battery life; 2. Sound reminder limitations: Sound alerts are ineffective in noisy environments (such as subways and gyms), making it easy for users to miss important calls; 3. Static clamping limitations: Traditional ear-clamping structures only provide a fixed clamping force and cannot convey information through tactile changes, resulting in a limited interaction method. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a clip-on Bluetooth headset with dynamic clamping force reminder function. It provides physical clamping force change reminders, is unaffected by environmental noise, and adopts a low-power electromechanical system, which greatly reduces power consumption compared to traditional vibration motor solutions.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A clip-on Bluetooth headset with dynamic clamping force reminder function includes a main earphone shell, a secondary earphone shell, and a curved clamping arm connecting the two, as well as various electronic components required for the operation of the Bluetooth headset. It also includes a dynamic clamping force assembly, which comprises a micro motor, clamping force adjustment blocks, and an elastic element. Two micro motors are fixedly installed inside the main and secondary earphone shells, respectively, with a rotating shaft at their output ends. Two clamping force adjustment blocks are fixedly connected to the rotating shafts inside the main and secondary earphone shells, respectively. The elastic element is elongated and curved, with its middle portion located inside the clamping arm, and its two ends connected to portions of the clamping force adjustment blocks away from the rotating shafts. The elastic element provides basic elasticity, ensuring that the clamping arm can return to its initial position. In the initial state, the earphones are worn on the user's ears, the clamp arms maintain a basic clamping force, and all components of the dynamic clamping force assembly are in their initial positions. When a call comes in, the Bluetooth module receives the signal and transmits it to the control circuit. The control circuit activates the micro motor, which drives the rotating shaft and the clamping force adjustment block on it to rotate. The clamping force adjustment block causes the two ends of the elastic element to move towards each other and deform, thereby pushing the clamp arms to tighten inward. The pressure of the main earphone shell and the secondary earphone shell on the ear increases, producing obvious tactile feedback to remind the user of the incoming call. The tightened state is maintained until the call ends or the user answers. Then, the micro motor reverses, and all components return to their initial state.

[0007] Preferably, the connection position between the clamping force adjusting block and the elastic element is provided with a connecting hole, and both ends of the elastic element are set as bent sections that can be inserted into the connecting hole, which makes the structure reliable and easy to assemble.

[0008] Preferably, limiting components are fixedly installed inside the main earphone shell and the secondary earphone shell, and the limiting components are located within the rotation path range of the clamping force adjusting block to limit the range of motion of the clamping force adjusting block and prevent the clamping arm from being over-tightened, causing user discomfort or equipment damage.

[0009] Preferably, the limiting member is in the shape of a round rod.

[0010] The beneficial effects of this utility model are as follows: 1. The product of this utility model provides reminders through physical clamping force changes, is unaffected by environmental noise, and has strong adaptability; 2. It adopts a low-power electromechanical system, which greatly reduces power consumption compared to traditional vibration motor solutions, and includes a clamping force adjustment block; 3. The mechanical transmission parts are simple and reliable, reducing production costs; 4. It provides intuitive reminders through perceptible clamping force changes, while avoiding discomfort caused by vibration and optimizing the user experience; 5. The clamping force change mode can support different application scenarios (such as incoming calls, messages, low battery reminders, or adjusting the clamping force when wearing the ear, etc.), making it versatile in function.

[0018] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0019] Example 1: As Figure 1 As shown, a clip-on Bluetooth headset with dynamic clamping force reminder function includes a main earphone shell 11, a secondary earphone shell 12, and a curved clamping arm 13 connecting the two.

[0020] Combination Figure 2-5 As shown, it also includes a dynamic clamping force assembly, which includes a micro motor 21, a clamping force adjustment block 22, and an elastic element 23.

[0021] The micro motor 21 is of two types, which are fixed in the main earphone shell 11 and the secondary earphone shell 12 respectively, and the output end is provided with a rotating shaft 24;

[0022] There are two clamping force adjustment blocks 22, which are fixedly connected to the rotating shafts 24 inside the main earphone shell 11 and the secondary earphone shell 12, respectively.

[0023] The elastic element 23 is slender and curved, with its middle part located inside the clamping arm 13, and its two ends connected to the parts of the clamping force adjusting block 22 that are away from the rotating shaft 24.

[0024] Example 2: Combination Figure 2-5As shown, based on Embodiment 1, the connection position between the clamping force adjusting block 22 and the elastic member 23 is provided with a connection hole 22.1, and both ends of the elastic member 23 are configured as bent sections that can be inserted into the connection hole 22.1.

[0025] Example 3: Combination Figure 2-5 As shown, based on Embodiment 1 or Embodiment 2, limiting members 25 are respectively fixedly installed inside the main earphone shell 11 and the secondary earphone shell 12, and the limiting members 25 are located within the rotation path range of the clamping force adjusting block 22. The limiting members 25 are in the shape of a round rod.

[0026] The working method is as follows: Figure 2-3 As shown, in the initial state, the earphone is worn on the user's ear, the clamping arm 13 maintains a basic clamping force, and all components of the dynamic clamping force assembly are in their initial positions. When a call comes in, the Bluetooth module receives the signal and transmits it to the control circuit. The control circuit activates the micro motor 21, which drives the rotating shaft 24 and its clamping force adjusting block 22 to rotate. The clamping force adjusting block 22 causes the two ends of the elastic element 23 to move towards each other, generating deformation, thereby pushing the clamping arm 13 to tighten inward. Figure 4-5 As shown, when the rotation stops upon contact with the limiting member 25, preventing the clamp arm from tightening further, the pressure on the ear increases from the main earphone shell 11 and the secondary earphone shell 12, generating obvious tactile feedback to remind the user of an incoming call. The tightened state is maintained until the call ends or the user answers, at which point the micro motor 21 reverses, and all components return to their initial state.

[0027] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. The present utility model can be used in similar products. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
