Description

Technical Field

[0001] This utility model belongs to the field of Bluetooth headsets, and in particular relates to a bone conduction Bluetooth headset with positioning and location tracking function. Background Technology

[0002] Most existing Bluetooth headsets feature a Find My function: based on Bluetooth technology, it enables headset loss alarms and location tracking, all with end-to-end encryption. When the headset and mobile app are paired and bound, if the headset is lost, the headset's information is transmitted via Bluetooth to a nearby mobile phone. The nearby phone then transmits the headset's location information to a server via the network. The owner can access the server through the mobile app to obtain the headset's location information. When the owner arrives near the headset's location with their mobile phone, the Bluetooth connection between the headset and the phone is re-established, and the headset automatically emits an alert sound, allowing the owner to locate the headset by following the direction of the sound.

[0003] Currently, the Find My function in Bluetooth earbuds is usually located on the charging case because the charging case is relatively large and has enough internal space to house the Find My function. However, due to the earbuds' smaller size and compact internal structure, no product currently places the Find My component inside the earbud itself. But consumers are more likely to lose the earbuds than the charging case during use; they are only likely to be recovered if both are lost. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a bone conduction Bluetooth headset with a positioning and finding function. Without significantly reducing product performance, it makes full use of the internal space of the headset to realize the Find My function in the headset body.

[0005] The technical solution provided by this utility model is as follows:

[0006] A bone conduction Bluetooth headset with positioning and locating function includes a neckband and ear hooks respectively disposed on both sides of the neckband. Both the neckband and ear hooks are hollow structures for wiring connections of internal components. Each ear hook includes a speaker assembly and a motherboard compartment or battery compartment at its end. The motherboard compartment contains a main circuit board that is connected to a battery in the battery compartment on the other side. The battery compartment or motherboard compartment also contains a Find My chip with positioning and locating function and its peripheral components.

[0007] Furthermore, the Find My chip and its peripheral components are integrated into the battery compartment; the battery compartment includes an upper shell and a lower shell, and a battery for powering the entire earphone is fixedly installed in the cavity formed by the upper shell and the lower shell. A Find My circuit board is provided on one side of the battery; the Find My chip and its peripheral components are integrated on the Find My circuit board, and the Find My button, which is directly opposite the Find My circuit board, is exposed outside the battery compartment through a through hole opened on the upper shell or the lower shell. The Find My button is used to control the function of Find My; a buzzer is provided on one side of the Find My circuit board, and the buzzer is directly opposite the sound outlet opened on the upper shell or the lower shell.

[0008] Furthermore, the Find My chip and its peripheral components are integrated into the motherboard compartment; the motherboard compartment includes an upper shell and a lower shell, and a main circuit board is fixedly installed in the cavity formed by the upper shell and the lower shell; the main circuit board integrates the headphone control module, the Find My chip and its peripheral components, and the Find My button, which is directly opposite the main circuit board, is exposed outside the motherboard compartment through a through hole opened on the upper shell or the lower shell. The Find My button is used to control the function of Find My; a buzzer is also provided on one side of the main circuit board, and the buzzer is directly opposite the sound outlet opened on the upper shell or the lower shell.

[0009] Furthermore, the Find My chip and its peripheral components are integrated into the motherboard compartment; the motherboard compartment includes an upper shell and a lower shell, and a main circuit board and a Find My circuit board connected to the main circuit board are fixedly installed in the cavity formed by the upper shell and the lower shell; the Find My circuit board integrates the Find My chip and its peripheral components, and the Find My button, which is directly opposite the Find My circuit board, is exposed outside the motherboard compartment through a through hole opened on the upper shell or the lower shell. The Find My button is used to control the function of Find My; a buzzer is also provided on one side of the main circuit board, and the buzzer is directly opposite the sound outlet opened on the upper shell or the lower shell.

[0010] Furthermore, the sound-emitting hole on the buzzer device corresponds to the sound-exiting hole opened on the upper or lower shell, the center misalignment between the sound-emitting hole and the sound-exiting hole does not exceed 3mm, and the distance from the sound-emitting surface of the buzzer to the inner side of the sound-exiting hole of the upper or lower shell is between 0 and 3mm.

[0011] Furthermore, a mesh is installed inside the sound outlet on the upper or lower shell that is directly opposite the buzzer. The mesh is used to adjust the sound quality and prevent foreign objects from entering the earphone.

[0012] Furthermore, a flexible soft component is provided between the Find My button and the push switch on the circuit board to achieve waterproofing and press-rebound, and this flexible soft component is connected to the housing by sealant.

[0013] Furthermore, the Find My button hole and the sound outlet hole are located at both ends of the same side of the upper or lower shell or on different sides.

[0014] Furthermore, when the Find My chip is integrated into the motherboard compartment, the antenna that comes with the Find My chip and the antenna on the main circuit board are placed at a certain angle to reduce mutual interference between the antennas.

[0015] Furthermore, the antennas that accompany the Find My chip and the antennas on the main circuit board are LDS antennas with laser-etched metal layers on the housing.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. The battery compartment space structure layout has been optimized. Instead of placing a single battery, the battery compartment now houses the battery, FindMy PCBA, and a buzzer, allowing all three to coexist without significantly reducing the battery capacity.

[0018] 2. To ensure the buzzer emits a sound level of at least 60dB at 30mm, a buzzer sound outlet is provided on the earphone shell. The sound from the buzzer is emitted through this outlet. The sound outlet on the buzzer must correspond to the sound outlet on the shell, with a center misalignment of no more than 3mm. The distance from the buzzer's sound-emitting surface to the inner side of the sound outlet on the shell should be between 0 and 3mm. A mesh is installed inside the sound outlet to adjust the sound quality and prevent debris from entering the earphone. The buzzer size should be 6.5*6.5*3mm or smaller, and the volume of the sound cavity at the front of the buzzer's sound outlet should be set between 0 and 30mm. 3 Within the range, ensure that the sound volume meets the requirement of 60dB or more at 30mm.

[0019] 3. Lower power consumption components are selected for the main PCBA and Find My PCBA, keeping the overall power consumption within a reasonable range. The overall battery life of the headphones still reaches more than 8 hours, which meets the needs of most consumers.

[0020] 4. The earphones are equipped with a Find My button switch, which is used to control the Find My function. There is a layer of soft material with good elasticity between the button and the push-button switch on the PCBA. The hardness can be selected between Shore A hardness 50 and 90A. This soft material is connected to the shell through a periphery sealing joint, thus realizing both the waterproof function of the button and the effective rebound after the button is pressed up and down.

[0021] 5. The antenna for Find My is located on the Find My PCBA, and the antenna for the main PCBA is located on the main PCBA; both are ceramic antennas. The Find My PCBA and the main PCBA are placed at a certain relative angle to reduce mutual interference between the antennas on both sides. The absolute value of this angle is set between 50 and 90 degrees, based on the angle formed when the wearer is wearing the device.

[0022] 6. If the Find My chip is integrated onto a separate PCBA, it can be placed on one side of the battery compartment. If space permits, the Find My chip can also be integrated into the main PCBA. When integrating the Find My chip into the main PCBA, to avoid altering the product's appearance, the component selection and implementation methods were optimized: a smaller Type-C female connector was chosen; the antenna was changed from a surface-mount ceramic antenna to an LDS antenna laser-engraved on the metal layer of the casing; and the board-end wiring connection method was changed from soldering to connectors. These adjustments not only enabled the integration of the Find My chip into the main PCBA but also prevented a reduction in battery size, ensuring a longer product lifespan.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] This embodiment provides a bone conduction Bluetooth headset with positioning and location tracking capabilities, such as... Figure 1 As shown, it mainly includes a neckband 1 and ear hooks 2 respectively located on both sides of the neckband 1. Both the neckband 1 and ear hooks 2 are hollow structures used for wiring connections of internal components. The ear hooks 2 specifically include a speaker assembly 3 at the end and a motherboard compartment 4 or battery compartment 5. For overall weight balance, the motherboard compartment 4 and battery compartment 5 are generally placed on the left and right sides respectively. The motherboard compartment 4 contains the main circuit board, which is connected to the battery in the battery compartment on the other side via wires.

[0034] The Find My chip, which has a location-finding function, and its peripheral components can be placed in the battery compartment 5 if they are fabricated on a separate circuit board; if space permits, the Find My chip can also be integrated into the motherboard compartment. The buzzer used to emit the alert sound is generally placed on the same side as the Find My chip.

[0035] like Figure 2 The diagram shows the Find My circuit board integrated into the battery compartment. The battery compartment 5 includes an upper shell 501 and a lower shell 502. A battery 503 is fixedly disposed within the cavity formed by the upper shell 501 and lower shell 502, providing power to the entire earphone. A Find My circuit board 505 is fixedly disposed on one side of the battery 503. The Find My circuit board 505 integrates the Find My chip and related components. The Find My button 506, directly opposite the Find My circuit board 505, is exposed outside the battery compartment 5 through a through-hole in the upper shell 501 or lower shell 502. The Find My button 506 controls the Find My functionality. A buzzer 504 is disposed on one side of the Find My circuit board 505, directly opposite a sound outlet 507 in the upper shell 501 or lower shell 502.

[0036] In some embodiments, the Find My chip is integrated into the motherboard compartment. Similarly, the motherboard compartment also includes an upper shell and a lower shell, and a main circuit board is fixedly disposed within the cavity formed by the upper and lower shells. The main circuit board integrates the entire headphone's control module and the Find My chip. Alternatively, the Find My chip and its related components can be mounted on a separate board and then connected to the main circuit board via wires or an FPC. In this case, a buzzer is also located in the motherboard compartment, and the upper or lower shell of the motherboard compartment has corresponding sound outlet holes and through holes for mounting the Find My button.

[0037] To ensure the buzzer emits a sound level of at least 60dB at 30mm, the sound-emitting hole on the buzzer must correspond to the sound-exit hole on the housing, with a center misalignment of no more than 3mm. The distance from the buzzer's sound-emitting surface to the inner surface of the sound-exit hole in the housing should be between 0 and 3mm. A mesh fabric is installed inside the sound-exit hole to adjust the sound quality and prevent debris from entering the earphone. Preferably, the buzzer size is 6.5*6.5*3mm or smaller, and the volume of the sound cavity at the front of the buzzer's sound-emitting hole is set to 0-30mm². 3 Within this range, it is understandable that the size and cavity volume of the buzzer can be set according to actual needs.

[0038] There is a soft material component with good elasticity between the Find My button and the push switch on the circuit board. Preferably, the hardness can be selected between Shore hardness 50 and 90A. This soft component is connected to the shell through peripheral sealing glue, thereby realizing the waterproof function of the button and the effective rebound effect after the button is pressed up and down.

[0039] When the Find My chip is integrated into the battery compartment, the antenna for Find My is located on the Find My circuit board, and the antenna for the main circuit board is located on the main circuit board. Both are ceramic antennas.

[0040] When the Find My chip is integrated into the motherboard compartment, there are two scenarios: Find My is integrated into the main circuit board, or the Find My circuit board is connected to the main circuit board. In both scenarios, the antenna of Find My and the antenna of the main circuit board are placed at a certain angle to reduce mutual interference between the antennas on both sides. Preferably, the relative angle is between 50 and 90 degrees, based on the angle formed by the wearer.

[0041] When integrating the Find My chip onto the main circuit board, a smaller Type-C female connector was chosen to avoid altering the product's appearance; the antenna type was changed from a surface-mount ceramic antenna to an LDS antenna laser-engraved on the metal layer of the housing; and the connection method for the board-end wires was changed from soldering to connectors. These adjustments achieved the integration of the Find My chip onto the main circuit board while minimizing excessive space occupation.

[0042] There are no strict restrictions on the layout of the Find My button hole 506 and the sound outlet hole 507 on the casing. For example... Figures 3-6 As shown, the Find My button hole 506 and the sound outlet hole 507 can be at opposite ends of the same side or on different sides. In some embodiments, the Find My button can even be shared with the volume buttons, in which case there is no need to create a separate Find My button hole.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical features of the above embodiments or different embodiments can be combined. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
