Description

Technical Field

[0001] The present invention relates to the technical field of Bluetooth earphones, and in particular to an ear-clip type Bluetooth earphone with a dynamic clamping force reminder function. Background Art

[0002] As a wearable smart device, clip-on Bluetooth headsets are widely used in sports, office and other scenarios because of their advantages such as being comfortable to wear and not affecting environmental perception.

[0003] Existing technologies mainly implement the call reminder function through vibration motors or sound prompts (earphone charging box), but the shortcomings are: 1. Vibration reminder defect: The built-in vibration motor vibrates continuously when a call comes in, requiring additional power support, increasing power consumption and shortening battery life; 2. Sound reminder defect: In noisy environments (such as subways, gyms, etc.), the sound reminder effect is poor, and users can easily miss important calls; 3. Static clamping limitation: The traditional ear clamping structure only provides a fixed clamping force and cannot transmit information through tactile changes, resulting in a single interaction method. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the above-mentioned prior art and provide an ear-clip Bluetooth headset with a dynamic clamping force reminder function, which reminds of physical clamping force changes and is not affected by environmental noise. It adopts a low-power electromechanical system and greatly reduces power consumption compared to traditional vibration motor solutions.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A clip-on Bluetooth headset with a dynamic clamping force reminder function comprises a main earphone housing, a secondary earphone housing, 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 micromotor, a clamping force adjustment block, and an elastic member. The micromotor is provided in two pieces and fixed in the main earphone housing and the secondary earphone housing, respectively, with a rotating shaft provided at the output end. The clamping force adjustment block is provided in two pieces and fixedly connected to the rotating shafts in the main earphone housing and the secondary earphone housing, respectively. The elastic member is slender and curved, with the middle portion located in the clamping arm and the two ends connected to the portion of the clamping force adjustment block away from the rotating shaft. The elastic member provides basic elastic force to ensure that the clamping arm can return to its initial position. In the initial state, the earphones are worn on the user's ears, the clamping arms maintain the basic clamping force, and the components of the dynamic clamping assembly are in the initial position. When a call comes in on the mobile phone, the Bluetooth module receives the signal and transmits it to the control circuit. The control circuit activates the micro motor, driving the rotating shaft and the clamping force adjustment block on it to rotate. The clamping force adjustment block drives the two ends of the elastic part to move toward each other and cause deformation, thereby pushing the clamping arms inward to tighten. The pressure of the main earphone shell and the auxiliary earphone shell on the ear increases, generating obvious tactile feedback to remind the user of the incoming call. The tightened state is maintained until the call ends or the user answers the call. The micro motor reverses and the components reset to the initial state.

[0006] Preferably, a connecting hole is provided at the connecting position between the clamping force adjustment block and the elastic member, and both ends of the elastic member are provided with bending sections that can be inserted into the connecting hole, so the structure is reliable and easy to assemble.

[0007] Preferably, limit members are fixedly provided in the main earphone shell and the auxiliary earphone shell respectively, and the limit members are located within the rotation path range of the clamping force adjustment block, and are used to limit the range of movement of the clamping force adjustment block to prevent the clamping arm from being over-tightened, causing discomfort to the user or damage to the equipment.

[0008] Preferably, the limiting member is in the shape of a round rod.

[0009] The beneficial effects of the present invention are: 1. The product of the present invention reminds through physical clamping force changes, is not affected 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 has 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 the discomfort caused by vibration and optimizing the user experience; 5. The clamping force change mode can support different scene applications (such as incoming calls, messages, low battery reminders, or adjusting the strength of clamping the ears when wearing, etc.), and has diversified functions.

DETAILED DESCRIPTION

[0012] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0013] Example 1: Figure 1 As shown, an ear-clip Bluetooth headset with a dynamic clamping force reminder function includes a main earphone shell 11, an auxiliary earphone shell 12 and a curved clamping arm 13 connecting the two.

[0014] Combine Figure 2-5 As shown, a dynamic clamping force assembly is also included, which includes a micro motor 21, a clamping force adjustment block 22 and an elastic member 23.

[0015] There are two micro motors 21, which are fixed in the main earphone shell 11 and the auxiliary earphone shell 12 respectively, and a rotating shaft 24 is provided at the output end; There are two clamping force adjustment blocks 22, which are fixedly connected to the rotating shafts 24 in the main earphone shell 11 and the auxiliary earphone shell 12 respectively; The elastic member 23 is slender and curved, with the middle portion located inside the clamping arm 13 and both ends respectively connected to portions of the clamping force adjustment block 22 away from the rotating shaft 24 .

[0016] Example 2: Combination Figure 2-5 As shown, based on the first embodiment, a connecting hole 22.1 is provided at the connecting position between the clamping force adjustment block 22 and the elastic member 23, and both ends of the elastic member 23 are provided as bending sections that can be inserted into the connecting hole 22.1.

[0017] Example 3: Combination Figure 2-5As shown, based on the first or second embodiment, a limiting member 25 is fixedly provided in each of the main earphone housing 11 and the auxiliary earphone housing 12, and the limiting member 25 is located within the rotation path of the clamping force adjustment block 22. The limiting member 25 is in the shape of a round rod.

[0018] The working method is: Figure 2-3 As shown, in the initial state, the earphones are worn on the user's ears, the clamping arm 13 maintains the basic clamping force, and the components of the dynamic clamping assembly are in the initial position. When the mobile phone calls, the Bluetooth module receives the signal and transmits it to the control circuit. The control circuit activates the micro motor 21, driving the rotating shaft 24 and the clamping force adjustment block 22 on it to rotate. The clamping force adjustment block 22 drives the two ends of the elastic member 23 to move toward each other and deform, thereby pushing the clamping arm 13 inward to tighten. Figure 4-5 As shown, when the rotation stops and contacts the limit piece 25, the clamping arm is prevented from further tightening. At this time, the pressure of the main earphone shell 11 and the auxiliary earphone shell 12 on the ear increases, and obvious tactile feedback is generated to remind the user of the incoming call. The tightened state is maintained until the incoming call ends or the user answers the call. The micromotor 21 reverses and each component resets to the initial state.

[0019] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. The present invention can be used on similar products. Any changes or modifications made by any technician in this field within the scope of the present invention are covered by the patent scope of the present invention.
