All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a bluetooth headset according to an embodiment of the present invention includes a bluetooth headset body, and a distance sensor and a head motion sensor that are disposed on the bluetooth headset body, and includes:
s1: the Bluetooth headset judges whether the Bluetooth headset is in a wearing state or not through the distance sensor.
The distance sensor detects the distance of objects by using the principle of the time-of-flight method, which calculates the distance between objects by measuring the time interval by emitting a particularly short light pulse and measuring the time from the emission of the light pulse to the reflection of the light pulse by the objects.
This step judges whether bluetooth headset wears in user's ear through the distance sensor who sets up in bluetooth headset, if bluetooth headset does not wear in user's ear, then the head motion sensor who sets up in bluetooth headset is out of work, can reduce bluetooth headset's consumption like this.
S2: and if the Bluetooth headset is in a wearing state, acquiring head motion data acquired by the head motion sensor.
A head motion sensor refers to a type of sensor that is capable of collecting data of a user's head motion, such as a three-axis acceleration sensor and a three-axis gyro sensor.
In this step, only after the bluetooth headset is worn in the ear of the user, the head motion sensor collects the head motion data of the user, so that the situation that the bluetooth headset is misjudged when the bluetooth headset is not worn in the ear of the user is avoided, and the actions of shaking the bluetooth headset by hand of the user and the like are misjudged as the actions of the head of the human body.
S3: and identifying the head action corresponding to the head action data according to a preset rule.
The head motion refers to a motion of pointing the head, turning the head left, or turning the head right of the user, the head pointing is a motion of pointing the head toward the lower front of the chest, the head shaking left refers to a motion of turning the head left with the neck as the base axis, the head shaking right refers to a motion of turning the head right with the neck as the base axis, or the head turning left or turning right may be expressed as turning the head toward the positive direction or turning the head toward the negative direction in terms of the designated axis.
In the step, after the user performs the head action according to the intention of the user, the head action data corresponding to the user can be generated, and the Bluetooth headset can identify the head action data into the corresponding head action according to the head action data acquired by the head action sensor and a preset rule, so that the intention of the user can be known.
S4: and sending a control instruction corresponding to the head action to the terminal equipment.
The terminal device refers to a device having an audio playing function or a call function, such as a bluetooth mobile phone.
In this step, the bluetooth headset sends a corresponding control instruction to the terminal device in communication connection with the bluetooth headset according to the identified head action of the user and according to the intention of the user, so as to control the terminal device to execute corresponding operation.

and S10, emitting infrared light outwards through the infrared emission module.
And S11, judging whether the infrared receiving module receives the reflected signal of the infrared light.
And S12, if yes, determining that the Bluetooth headset is in a wearing state, otherwise, determining that the Bluetooth headset is not in the wearing state.
In this embodiment, the infrared emitting module of the distance sensor is used to emit infrared light outwards, and then whether the infrared receiving module receives a reflected signal of the infrared light is determined, so as to determine whether the bluetooth headset is worn in the ear of the user. When infrared receiving module received the reflection signal of infrared light, then can judge that bluetooth headset wears in user's ear, later head action sensor just begins to gather user's head action data, can avoid effectively like this if bluetooth headset is not in the wearing state, and bluetooth headset probably appears the misjudgement, shakes actions mistake such as bluetooth headset with the hand with the user and thinks that human head has taken place the action to make terminal equipment maloperation appear.
Further, in another embodiment of the present invention, the head motion sensor includes a three-axis acceleration sensor provided with an interrupt mode activation mechanism, and step S3 includes:
and S30, judging whether the head action corresponding to the head action data activates the interrupt mode.

The three-axis gyroscope sensor can be used for measuring angular velocity values on three axes, and only the angular velocity value of one axis needs to be measured. Since the angular velocity value measured by the three-axis gyro sensor chip affected by the patch direction is an angular velocity value generated in one of the three axes, the above-mentioned designated axis may be any one of the three axes, and preferably, an axis located at a connection line between both ears of the user may be set as the above-mentioned designated axis.
In addition, the magnitude of the measured angular velocity value needs to be concerned, when the head of the user is not rotated and is still, the angular velocity value is 0, the angular velocity is generated when the head of the user rotates, when the head of the user returns to the original still position after rotating to the left or the right, a wave peak value is generated on the designated axis, the head is rotated to the left to be the positive direction of the axis, the first preset threshold value can be 1/3 of the positive wave peak value, and similarly, the preset head is rotated to the right to be the negative direction of the axis, and the second preset threshold value can be 1/3 of the reverse wave peak value.
And S33, if yes, determining that the head movement is towards positive direction turning or determining that the head movement is towards negative direction turning in a one-to-one correspondence mode.

Compared with the prior art, the Bluetooth headset play control method and the Bluetooth headset provided by the invention have the following beneficial effects: firstly, whether the Bluetooth headset is worn in the ear or not is judged by using the distance sensor, and only after the Bluetooth headset is judged to be worn in the ear, the head action sensor starts to collect the head action data of the user, so that the possibility of misjudgment of the Bluetooth headset can be effectively avoided, for example, the user shakes the Bluetooth headset with a hand to misjudge that the action of the human head is the action, and the terminal equipment is misoperated. And then the Bluetooth headset identifies the head action corresponding to the head action data according to a preset rule, and sends a corresponding control instruction to the terminal equipment in communication connection with the Bluetooth headset, so that the terminal equipment can execute corresponding operation according to the head action of a user. In addition, whether the head posture of the user is upright or not is judged by using the three-axis acceleration sensor, and only after the head posture of the user is judged to be upright, the three-axis acceleration sensor and the three-axis gyroscope sensor start to acquire the head action data of the user, so that the power consumption of the Bluetooth headset is effectively reduced, and the possibility of misjudgment of the Bluetooth headset is effectively avoided, for example, actions such as turning when the head of the user is in a lying posture are mistaken for the action of the head of the human body, and therefore the terminal equipment is misoperated. According to the invention, a user can replace the button function of the Bluetooth headset through the action of the head without pressing certain buttons of the Bluetooth headset by hands in the whole process, for example, when listening to music, the user can select playing music or pausing music through nodding, and select the next or previous song through forward turning or reverse turning, so that the operation is simple and convenient, the miniaturization of the Bluetooth headset is facilitated, the possibility of misjudgment of the Bluetooth headset can be avoided, and the user experience is improved.
