[0031] Apple Find My technology can significantly improve positioning accuracy and tracking ability by using Bluetooth signal and extensive device network.More importantly, Find My technology relies on existing Apple device, without additional hardware support, to ensure that earphone maintains low cost while providing efficient positioning service, and the selling price is more competitive.

[0032] The following first introduces Find My function.

[0033] To use Find My function, first, the Bluetooth master control chip of Bluetooth glasses needs to be paired with apple mobile phone.The pairing process is as shown in Figure 2 After pairing, user can enable positioning function, and the positioning function process of apple mobile phone is as shown in Figure 3

[0034] When Bluetooth glasses are lost, Bluetooth master control chip will emit Bluetooth signal at certain time interval, and the signal contains device identity information etc.After the signal is received by surrounding apple device or other device supporting Find My network and enabling corresponding function, the existence of Bluetooth glasses with Find My function can be identified.

[0035] ​When a user looks for the Bluetooth glasses through the Find My application on an Apple device, the find instruction is transmitted through the Bluetooth network. After the chip receives the find instruction from the nearby Apple device, it transmits the data such as the position information stored by itself to the Apple device through Bluetooth, and then the Apple device uploads the data to the iCloud server, and finally feeds back the positioning information to the user APP, helping the user to determine the approximate position of the Bluetooth glasses.

[0036] In this embodiment, the model of the Bluetooth master chip is JL7003D.

[0037] The JL7003D chip is a Bluetooth 5.0 protocol supporting chip with the characteristics of low power consumption and high integration. The JL7003D master IC plays a core control role in the Find My Bluetooth glasses, integrates a charging management circuit, and is responsible for the charging function of the battery. At the same time, it cooperates with the C7A20 three-axis acceleration sensor to monitor the motion state of the Find My Bluetooth glasses in real time. The JL7003D also manages the Find My function, helps to locate the lost Find My Bluetooth glasses through Bluetooth signals. In addition, the master IC also realizes the functions of turning on and off, music control, and call management through physical buttons, and displays the working state of the device through the LED indicator light, improving the user experience. The circuit of the Bluetooth master chip is shown in Figure 4 .

[0038] In this embodiment, the motion detection module uses the SC7A20E three-axis acceleration sensor.

[0039] In this embodiment, the Find My Bluetooth glasses Find My protocol designs a motion detection function. When someone's Find My device is mixed in your personal belongings, and in the separated state (i.e. the device is away from the owner's device) and the tracking time exceeds a certain time (3 days), the device will automatically start the acceleration sensor (gsensor) to detect whether the movement occurs. Once the movement is detected, the device will make a sound to remind you that you are being tracked by the Find My device. In the opposite way, this function can also detect whether your device is secretly carried by others. The circuit of the motion detection module is shown in Figure 5 .

[0040] As shown in Figure 5 , the motion detection module includes chip U3 and capacitor C10, pin 2 of chip U3 is connected to pin 14 of the Bluetooth master chip, pin 3 of chip U3 is connected to one end of capacitor C10 and pin 2 of the Bluetooth master chip, the other end of capacitor C10 is grounded, pin 4, pin 8 and pin 9 of chip U3 are grounded, pin 5 of chip U3 is connected to pin 10 of the Bluetooth master chip, pin 7 and pin 11 of chip U3 are connected to pin 2 of the Bluetooth master chip, and pin 12 of chip U3 is connected to pin 15 of the Bluetooth master chip.

The anode of the light-emitting diode LED1 is connected to pin 2 of the Bluetooth master chip, and the cathode of the light-emitting diode LED2 is connected to ground. The other end of the resistor R1 is connected to pin 3 of the Bluetooth master chip.

[0043] Further, in this embodiment, the sound emitting module of the Find My Bluetooth glasses not only supports playing music and answering calls, but also has the function of finding glasses. When the user accidentally loses the glasses, the user can remotely control the speaker to emit sound through the phone or other devices to help locate the position of the glasses and find them quickly. The circuit diagram of the sound emitting module is shown in Figure 7 .

[0044] As shown in Figure 7 , the sound emitting module includes a capacitor C11, a capacitor C12, an inductor L4, and an inductor L5.

The JL7003D will monitor the battery status in real time to prevent overcharging or overdischarging, and prolong the service life of the battery. In this embodiment, the circuit diagram of the charging module is shown in Figure 8 .

[0046] Further, in this embodiment, the Find My Bluetooth glasses are equipped with physical keys, which can be turned on or turned off by long pressing. When turned on, the power management module is triggered and enters the pairing mode. When turned off, all functions are stopped to save battery. The keys also support short pressing operations, such as playing / pausing music, answering / hanging up the phone, etc. In this embodiment, the circuit diagram of the key module is shown in Figure 9 .

[0047] As Figure 9 shown, the key module includes a key KEY1, one end of the key is grounded, and the other end is connected with pin 9 of the Bluetooth master chip.
