The embodiment of the present invention discloses a wireless earphone and a wearing detection system and method thereof to reduce the possibility of false triggering and enhance user experience.

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Please refer to FIG. 1, which is a structural block diagram of a wireless earphone wearing detection system according to a specific embodiment of the present invention.

In this embodiment, the wireless headset wearing detection system provided by the present invention includes a processor 103 and at least two proximity sensors 101. It should be noted that the wireless headset mentioned in the present invention may specifically be a TWS headset.

Wherein, at least two proximity sensors 101 are arranged at different positions on the wireless headset on the side close to the target object, each proximity sensor 101 is used to detect whether it is close to the target object, and at least one of the proximity sensors 101 is an ultrasonic sensor. It should be noted that the side close to the target object includes both the position on the wireless headset close to the face. Of course, the close to the face here refers to the position close to the face when the wireless headset is worn, and it also includes the position on the wireless headset that is close to the face when worn. The position of the pinna. The location of each proximity sensor 101 is different, and the specific location can be set as required, which is not specifically limited here. The specific preset value setting can be set according to the shape of the wireless headset and the wearing state of the wireless headset determined by it, and there is no specific limitation here.

At least one of the proximity sensors 101 is an ultrasonic sensor. The internal logic of the ultrasonic sensor can be specifically shown in Figure 2. The clock line (SCL) and data line (SDA) of the ultrasonic sensor are connected to the micro control unit (MCU). The working process is as follows: the internal ultrasonic pulse is sent after an obstacle is encountered Reflect, and then process the received reflected ultrasonic signal through the internal analog-to-digital converter (ADC). The signal is transmitted to the MCU through I2C (SDA and SCL), and the speed of sound wave propagation in the air is 343m/s. The MCU uses the transmission time Through internal signal processing, the distance from the obstacle to the microelectromechanical system (MEMS) ultrasonic sensor can be obtained. The use of ultrasonic sensors has the advantages of accurate measurement, non-contact, waterproof, anti-corrosion, and low cost. The ultrasonic sensor in this application preferably adopts a MEMS (microsystem) ultrasonic sensor. The remaining proximity sensors 101 may specifically be infrared proximity sensors, laser proximity sensors and other proximity sensors using light sensing, or touch proximity sensors using capacitance detection.

The processor 103 is electrically connected to each proximity sensor 101, and is used to determine whether the wireless headset is in a wearing state according to the detection result of each proximity sensor 101. Specifically, the proximity sensor 101 may send a trigger signal to the processor 103 when the distance to the target object is less than a preset value, and the processor 103 determines that the proximity sensor 101 is effectively approaching according to the received trigger signal. When the wireless headset is worn, one side of the wireless headset will be close to or close to the target object, which is then detected by the proximity sensor 101, and the detection results of the multiple proximity sensors 101 are used together as a judgment basis for wearing detection, which is more accurate.

Using the wireless headset wearing detection system provided by the present invention, each proximity sensor 101 detects whether it is close to a target object, and the processor 103 determines whether the wireless headset is in a wearing state according to the detection result of the ultrasonic sensor. That is, the detection of multiple proximity sensors 101 is combined to make a wearing determination. Furthermore, when the wireless headset is taken, it is generally difficult for the user to touch multiple proximity sensors 101 at the same time, and accidentally touching a position of the proximity sensor 101 will not directly cause false triggers, thus significantly reducing false triggers The possibility of enhancing the user experience. The wearing detection method of the wireless earphone of the present application can be implemented by the above-mentioned detection system, which also has the above-mentioned beneficial effects.

The wireless headset wearing detection system provided by the present invention, on the basis of the above content, as a preferred embodiment, the processor 103 is specifically configured to determine that each proximity sensor 101 is in sequence according to the detection result of the proximity sensor 101 in a preset sequence. When it is effectively approaching, it is determined that the wireless headset is in a wearing state. That is, after judging that the proximity sensor 101 is effective proximity based on the detection result of the previous proximity sensor 101, then judging whether the proximity sensor 101 is effective proximity based on the detection result of the next proximity sensor 101, when it is determined that the last proximity sensor 101 is effective When approaching, it is determined that the wireless headset is in a wearing state. This arrangement simplifies the workload of the processor 103 and improves the speed of wearing detection. According to needs, if the processing capability allows, the proximity sensors 101 can also work at the same time. The processor 103 is specifically configured to determine that the proximity sensors 101 are all effective proximity based on the detection results of the proximity sensors 101 at the same time, and then determine the wireless The headset is in the wearing state.

Further, each proximity sensor 101 performs detection in sequence according to the above preset sequence, that is, the processor 103 is specifically configured to control the first proximity sensor 101 to perform detection according to the preset sequence, and perform detection according to the detection result of the first proximity sensor 101 When it is determined that the proximity sensor 101 is effectively approaching, the next proximity sensor 101 is controlled to perform detection. When the corresponding proximity sensor 101 is determined to be effective proximity based on the detection result of the proximity sensor 101, the next proximity sensor 101 is then controlled to perform detection, and so on Until it is determined that the last proximity sensor 101 is effectively approaching, it is determined that the wireless headset is in the wearing state, otherwise, it is in the non-wearing state. That is, the proximity sensors 101 work sequentially without real-time work. On the one hand, it is beneficial to prolong its service life, and it can also reduce the power consumption of the wearing detection system.

The wireless earphone wearing detection system provided by the present invention, on the basis of the above content, as a preferred embodiment, further includes an inadvertent touch prevention proximity sensor 102 arranged on the side of the wireless earphone away from the target object. 102 is used to detect whether it is close to the target object. The processor 103 is electrically connected to the anti-mistouch proximity sensor 102, and is used to determine that each proximity sensor 101 is an effective proximity based on the detection result of each proximity sensor 101, and according to the anti-mistouch When the detection result of the false touch proximity sensor 102 determines that the false touch prevention proximity sensor 102 is not approaching, it is determined that the wireless headset is in the wearing state. That is, an anti-mistouch proximity sensor 102 is added to the side of the wireless headset facing away from the target object, where the side facing away from the target object refers to the side facing away from the target object when the wireless headset is worn. The anti-mistouch proximity sensor 102 may specifically be a sensor using capacitance detection. Since the user wears the wireless headset, the side facing away from the target object is not in contact with the human body, so the false touch prevention proximity sensor 102 is not approaching, and when the user holds the wireless headset with his hand, or places the wireless headset in the trouser pocket, each The proximity sensors 101 are all effective proximity. By setting the false touch prevention proximity sensor 102, the processor 103 can determine that the wireless headset is in a non-wearing state through the detection of the false touch prevention proximity sensor 102 in the above situation. In summary, by setting the proximity sensor 102 to prevent false touches, the probability of false triggering when the wireless headset is placed in a trouser pocket can be effectively prevented.

Further, in the case where a touch sensor is provided on the side of the wireless headset facing away from the target object, the accidental touch prevention proximity sensor 102 and the touch sensor are arranged in different positions to prevent the user from touching the prevention device when the operation is triggered by the touch sensor. The proximity sensor 102 is touched by mistake, causing a misjudgment of wearing detection. Among them, the touch sensor may specifically be a sensor using capacitance detection. The touch sensor is used to be triggered when it contacts the target object, and sends a trigger signal to the processor 103 to trigger a corresponding operation.

Furthermore, the inadvertent touch prevention proximity sensor 102 can be specifically set to work when the touch sensor is not triggered, and when the touch sensor is triggered, it does not work, and it is only detected by the proximity sensor 101 arranged on the side close to the target object. .

On the basis of the foregoing embodiments, at least one proximity sensor 101 is disposed on the side of the ear stem of the wireless headset, and at least one proximity sensor 101 is disposed on the top surface of the earplug of the wireless headset. That is, the proximity detection is performed from different directions, making the detection structure more reliable. It can be specifically shown in Figure 3. Figure 3 is a schematic diagram of the detection point setting on the wireless headset. The wireless headset 2 is worn on the human auricle 1. The proximity sensor 4 and the proximity sensor 5 are set on the side of the ear stem of the wireless headset 2, and A proximity sensor 6 is provided on the top surface of the earplug of the wireless earphone, and a proximity sensor 3 is provided on the side of the wireless earphone away from the target object.

The following describes the wearing detection method of the wireless headset provided by the present application.

When the wireless headset is taken, even if the user accidentally touches a certain proximity sensor position, it will not directly cause false triggering, thus significantly reducing the possibility of false triggering and enhancing the user experience.

Further, the step S12 specifically includes:

According to a preset sequence, when it is determined that each of the proximity sensors is a valid proximity according to the detection result of the proximity sensor, it is determined that the wireless headset is in a wearing state.

Specifically, in each of the foregoing embodiments, an anti-mistouch proximity sensor is provided on the side of the wireless headset away from the target object, and the anti-mistouch proximity sensor is used to detect whether the target object is approaching;

Then step S12 specifically includes:

When it is determined according to the detection result of each of the proximity sensors that each of the proximity sensors is a valid proximity, and according to the detection result of the anti-mis-touch proximity sensor, it is determined that the anti-mis-touch proximity sensor is not approaching, it is determined that the wireless headset In the wearing state.

That is, the ultrasonic sensor 201 detects whether it is close to the target object as a judgment basis for wearing detection. In order to facilitate detection, the ultrasonic sensor 201 may be specifically arranged on the side of the wireless earphone close to the target object. It is generally set on the side of the wireless headset that is close to the human face. Of course, the term "close to the human face" here refers to the side that is close to the human face when the wireless headset is worn. According to needs, it can also be arranged on the side of the wireless earphone close to the auricle in the wearing state. For the specific structure and principle of the ultrasonic sensor 201, please refer to the above-mentioned embodiment, which will not be repeated here.

When the motion detection sensor 202 is used to detect the motion of the wireless headset, the processor 203 is used to compare the detection result of the motion detection sensor 202 with a preset motion. When the motion detection sensor 202 is used to detect the posture of the wireless headset, the processor 203 is used to compare the detection result of the motion detection sensor 202 with the preset posture. Specifically, the ultrasonic sensor 201 may send a trigger signal to the processor 203 when the distance to the target object is less than a preset value, and the processor 203 determines that the proximity sensor is a valid approach according to the received trigger signal. When wearing a wireless headset, on the one hand, one side of the wireless headset will approach or fit the target object, on the other hand, the wireless headset will rotate to a certain angle.

That is, the processor 203 first determines whether the ultrasonic sensor 201 is effectively close, and if so, it compares whether the detection result of the motion detection sensor 202 meets the preset motion or preset posture. This setting simplifies the workload of judgment and comparison and improves the wearing The speed of detection. According to needs, if the processing capacity permits, it can also be determined at the same time whether the ultrasonic sensor 201 is effectively approaching, and whether the detection result of the motion detection sensor 202 meets the preset action or preset posture.
