[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] see figure 1 , figure 1 It is a schematic structural diagram of a bluetooth headset that realizes automatic on-off through a smart wearable contact device in a preferred embodiment of the present invention. The bluetooth headset 1 of this embodiment can communicate with a smart phone (not shown) through a smart wearable contact device 2, and This communication can be switched on and off automatically.

[0025] Generally, the smart wearable contact device 2 is usually wirelessly connected with the smart phone so that information can be transmitted between them. The wireless connection manner may be bluetooth, wifi (Wireless-Fidelity, wireless fidelity) or ZigBee (Zigbee protocol). In the human body communication technology, the smart wearable contact device 2 usually includes a second power supply tube module 21, a second human body communication module 22 and a second control module 23, and the second power supply tube module 21 is used for the second human body communication module 22 and the second control module 23. The second control module 23 provides power, and the second human body communication module 22 is in contact with the user's human body and is electrically connected with the second control module 23 for generating a second human body communication signal. The smart wearing contact device 2 can be a smart bracelet or a smart watch.

[0026] The Bluetooth headset 1 of this embodiment includes a first power supply tube module 11 , a motion detection module 12 , a first control module 13 , a first human body communication module 14 and an earphone module 15 . The first power tube module 11 is used to provide power for the first human body communication module 14, the first control module, the earphone module 15 and other electronic modules in the Bluetooth earphone 1, and the first control module 13 is electrically connected with the motion detection module 12 for motion detection. The module 12 is used to detect the user's use action. The use action can be a wearing action or a removal action in contact with the user's human body. When the action detection module 12 detects that the use action is a wearing action in contact with the user's human body, the action detection module 12 will feed back to the first control module 13 to generate a trigger signal. . The first human body communication module 14 is electrically connected to the first control module 13 and used for sending a first human body communication signal based on the trigger signal. Wherein, the first control module 13 is also used to search for the second human body communication signal coupled with the first human body communication signal and establish a human body communication connection, so that the Bluetooth headset 1 and the smart wearable contact device 2 can transmit information through human body communication. Since information can be transmitted between the smart wearable contact device 2 and the smart phone, the Bluetooth headset 1 can sequentially transmit information through the human body communication, and the smart wearable contact device 2 indirectly with the smart phone. The earphone module 15 is electrically connected with the first human body communication module 14, and is used for communicating based on the connection between the Bluetooth earphone 1 and the smart phone. The communication can be making a phone call, listening to music, and the like.

[0027] The motion detection module 12 may be an acceleration sensor, or other sensors responsible for motion detection. Specifically, the bluetooth headset 1 is originally in a static state in a certain position or in the ear. When the user picks up the wearing or removes the stationary bluetooth headset 1 from a certain position, the bluetooth headset 1 changes from the static state to In the state of exercise, the acceleration sensor, which has been in a low-energy working state, detects the speed change of the user’s wearing or removing action at this time, and then feeds back to the first control module 13, so that the first control module 13 generates a trigger signal to start the first human body communication module 14.

[0028]Further, the first human body communication module 14 of this embodiment includes a first human body sensing module 141 and a first human body control module 142, and the first human body sensing module 141 is used to detect whether the Bluetooth headset 1 is in contact with the user's body based on the trigger signal. The first human body sensing module 141 can be located at the ear-in-ear portion of the Bluetooth headset 1 to be in contact with the user's auricle and the skin inside the ear, so as to ensure that the human body communication is always connected when the user uses the Bluetooth headset 1 for communication. Of course, the first human body sensing module 141 can also be extended from the ear-in-ear part to the convenient finger contact part of the Bluetooth headset 1, so that the user can quickly establish human body communication with the smart wearable contact device 2 when picking up the Bluetooth headset 1 but not putting it on the ear. , improving the turn-on efficiency of the Bluetooth headset 1 . The first human body control module 142 is electrically connected with the first human body sensing module 141, and is used for generating a first human body communication signal when the first human body sensing module 141 detects that the Bluetooth headset 1 is in contact with the user's human body.

[0029] The second human body communication module 22 includes a second human body sensing module 221 and a second human body control module 222. The second human body sensing module 221 is used to detect whether the smart wearable contact device 2 is in contact with the user's human body. The second human body control module 222 is electrically connected to the second human body communication module 22, and is used for generating the second human body communication signal when it is detected that the smart wearable contact device 2 is in contact with the user's human body.

[0030] The first human body control module 142 and the second human body control module 222 can use the AS3900 chip of Austriamicrosystems (ams), or other low power consumption chips.

[0031] Please also refer to figure 2 , figure 2 It is a schematic structural diagram of another preferred embodiment of the present invention, a bluetooth earphone that realizes automatic on-off through a smart wearable contact device. The human body communication connection may be unstable, and there is certain interference during information transmission, so the Bluetooth headset 1 of this embodiment further includes a Bluetooth module 16 to realize Bluetooth pairing connection with a smart phone through the smart wearable contact device 2 . This embodiment is substantially the same as the above-mentioned embodiments, except that the Bluetooth headset 1 in this embodiment further includes a Bluetooth module 16 .

[0032] Smart phones in the prior art generally have a Bluetooth function, which is a mature technology, so details will not be described here. The Bluetooth module 16 in this embodiment is electrically connected to the first control module 13, wherein the first control module 13 in this embodiment is also used to generate a Bluetooth pairing signal based on the above-mentioned human body communication. The bluetooth module 16 is used to process the bluetooth pairing signal and send the bluetooth pairing signal through the human body communication, because the smart wearable contact device 2 and the smart phone are connected wirelessly, that is, information can be transmitted between each other, so the smart wearable contact device 2 receives The Bluetooth pairing signal of the Bluetooth headset 1 is sent to the smart phone to form a Bluetooth transmission channel for pairing and connection with the Bluetooth of the smart phone, so that the Bluetooth headset 1 directly transmits information with the smart phone through the Bluetooth transmission channel, improving the stability and stability of information transmission. efficiency.

[0033] Further, in other embodiments, after the Bluetooth headset 1 is paired and connected with the Bluetooth of the smart phone to form a Bluetooth transmission channel, the first control module 13 turns off the first human body sensing module 141 to reduce the power consumption of the Bluetooth headset 1 .

[0034] Furthermore, in other embodiments, the Bluetooth headset 1 also includes a timing module 17, the timing module 17 is electrically connected to the first human body sensing module 141, and is used to regularly start the first human body sensing module 141 to detect whether the Bluetooth headset 1 is still When it is in contact with the user's body, if there is no contact, it will be fed back to the first control module 13 to turn off the Bluetooth module 16 in time.

[0035] It is worth noting that when the motion detection module 12 detects that the use action is a removal motion, the motion detection module 12 will feed back to the first control module 13 to generate a trigger signal, and the first human body sensing module 141 detects whether the Bluetooth headset 1 is based on the trigger signal. In contact with the user's human body, when the first human body sensing module 141 does not detect that the Bluetooth headset 1 is in contact with the user's human body, it sends a Bluetooth shutdown signal to the first control module 13, so that the first control module 13 turns off the headset module sequentially based on the Bluetooth shutdown signal 15. The Bluetooth module 16, the first human body communication module 14, and finally make the first control module 13 and the motion detection module 12 in a dormant state to reduce their power consumption.

[0036] To sum up, during the whole process of turning on the Bluetooth headset 1, the first control module 13, the first human body communication module 14, the Bluetooth module 16, and the earphone module 15 are turned on sequentially. If it is considered to be misoperation or removal of the Bluetooth headset 1, the above-mentioned modules are turned off in reverse order, and only the ultra-low working state of the first control module 13 and the motion detection module 12 is maintained.

[0037] see image 3 , image 3 It is a flowchart of a method for realizing automatic connection of a Bluetooth headset through a smart wearing contact device in a preferred embodiment of the present invention. The contact device 2 and the smartphone have been wirelessly connected to transmit information between each other, and the wireless connection may be Bluetooth, wifi (Wireless-Fidelity, wireless fidelity) or ZigBee (Zigbee protocol). The smart wearable contact device 2 includes a second body communication module 22 and a second control module 23. The second body communication module 22 is in contact with the user's body and is electrically connected to the second control module 23 to generate a second body communication signal. Specifically, the method of this implementation includes the following steps:

[0038] S10: Detect user action;

[0039] Specifically, the action detection module 12 detects a user's use action, which may be a wearing action or a removal action that contacts the user's body. The motion detection module 12 may be an acceleration sensor, or other sensors responsible for motion detection. The acceleration sensor mainly detects the speed change of the Bluetooth headset 1 from stillness to motion, preferably, the acceleration sensor detects the speed change of the Bluetooth headset 1 from rest to motion in the direction of gravity. Of course, the wearing action or removal action of the Bluetooth headset 1 will change in the horizontal and gravity directions, so the acceleration sensor can also detect the speed change of the Bluetooth headset 1 when it moves from stillness to the horizontal direction, or the direction of gravity and the horizontal direction. The acceleration sensor corresponding to the detection standard can be selected according to actual needs, and it is not limited here.

[0040] S20: Generate a trigger signal when it is detected that the use action is a wearing action in contact with the user's body;

[0041] Specifically, the detection module feeds back to the first control module 13 when it detects that the use action is a wearing action or a removal action in contact with the user's body, so that the first control module 13 generates a trigger signal to activate the first human body communication module 14 .

[0042] Among them, the bluetooth earphone 1 was originally in a static state. When the user picks up or removes the stationary bluetooth earphone 1, the bluetooth earphone 1 changes from a stationary state to a motion state, and the acceleration sensor, which has been in a low-power working state, detects The speed change of the user's wearing action is fed back to the first control module 13 , so that the first control module 13 generates a trigger signal to activate the first human body communication module 14 .

[0043] S30: Generate a first human body communication signal based on the trigger signal;

[0044] Specifically, the first human body control module 142 generates a first human body communication signal based on the trigger signal. Wherein, since the user's fingers will be in contact with the Bluetooth headset 1 when wearing or taking it off, the human body will generate the first human body communication signal. However, the wearing action finally places the Bluetooth headset 1 on the user's ear, so that the Bluetooth headset 1 is kept in contact with the user's body from being picked up to being placed in the ear, and the finger of the removal action finally releases the Bluetooth headset 1, that is, it does not contact the Bluetooth headset 1. Therefore, the trigger signal generated under the final removal action makes the first human body control module 142 unable to continuously generate the first human body communication signal.

[0045] S40: Search for a second human body communication signal coupled with the first human body communication signal and generated by the smart wearable contact device 2 and establish a human body communication connection, so as to further connect a smart phone through the smart wearable contact device 2 for communication.

[0046] Specifically, the first control module 13 searches for the second human body communication signal coupled with the first human body communication signal and generated by the smart wearable contact device 2 and establishes a human body communication connection so that the Bluetooth headset 1 and the smart wearable contact device 2 pass through the human body. Communication transmits information. Since information can be transmitted between the smart wearable contact device 2 and the smart phone, the Bluetooth earphone 1 can sequentially transmit information through the human body communication, and the smart wearable contact device 2 indirectly with the smart phone.

When the Bluetooth headset 1 receives the big data information transmitted from the smart phone to the smart wearable contact device 2 through human body communication, consider The human body communication connection may be unstable, and there is certain interference during information transmission, so the above-mentioned implementation is further improved.

The point is that the Bluetooth in the method of this embodiment is further paired and connected with the Bluetooth of the smart phone through the smart wearable contact device 2 to form a Bluetooth transmission channel, so that the Bluetooth headset 1 directly transmits information with the smart phone through the Bluetooth transmission channel, improving information transmission. stability and efficiency.

[0052] Wherein, the bluetooth earphone 1 is originally in a static state, and when the user needs to use the bluetooth earphone 1, he picks up and wears the still bluetooth earphone 1.

Of course, the first human body The sensing module 141 can also be extended from the ear-entry part to the convenient finger contact part of the Bluetooth headset 1, so that the user can quickly establish human body communication with the smart wearable contact device 2 when picking up the Bluetooth headset 1 without putting it on the ear, and improve the Bluetooth headset 1. opening efficiency.

[0062] S412: Generate the second human body communication signal when contact with the user's human body is detected;

[0063] Specifically, the second human body control module 222 generates the second human body communication signal when it is detected that the smart wearable contact device 2 is in contact with the user's human body.

[0064] S50: Based on the human body communication, regularly detect whether it is still in contact with the user's human body, and if not, disconnect the human body communication;

[0065] Specifically, the timing module 17 regularly activates the first human body sensing module 141 to detect whether the Bluetooth headset 1 is still in contact with the user's body, and if not, feeds back to the first control module 13 to turn off the Bluetooth headset 1 in time.

[0072] This step is the same as the above step S10.

[0073] S22: Generate a trigger signal when it is detected that the use action is an extraction action;

[0074] Specifically, the motion detection module 12 feeds back to the first control module 13 when detecting that the use motion is an exfoliation motion, so that the first control module 13 generates a trigger signal to start the first human body control module 142 .

[0075] Among them, the bluetooth earphone 1 is in a static state when the earphone is in the original state. When the user removes the stationary bluetooth earphone 1 from the earphone, the bluetooth earphone 1 changes from a stationary state to a motion state, and the acceleration sensor, which has been in a low-power working state, detects The speed change of the user's removal action is fed back to the first control module 13 , so that the first control module 13 generates a trigger signal to activate the first human body control module 142 .
