The earphone 10 is a pair of conversion units, which receives the electric signal from the media player or receiver and converts it into audible sound waves by the speaker 200 near the ear. The media player or the receiver may be an electronic device, and the electronic device may be any device having an audio playing function. For example: the system comprises intelligent equipment with an audio playing function, such as a tablet Computer, a mobile phone, an electronic reader, a remote controller, a Personal Computer (PC), a notebook Computer, vehicle-mounted equipment, a network television, wearable equipment and the like.

In one embodiment, the earphone 10 further comprises a main body portion 100, wherein the main body portion 100 is a housing portion of the earphone 10, and the main body portion 100 forms an integral frame of the earphone 10. The speaker 200 is mounted in the main body 100 and outputs sound. The distance between the earphone 10 and the user's ear can be considered as the distance between the main body portion 100 and the user's ear. The earphone 10 may be considered to be worn on the ear of the user as the main body 100 is worn on the ear of the user.

Microprocessor 400 may be a microchip, which is a central processing unit consisting of one or a few LSIs. These circuits perform the functions of the control unit and the arithmetic logic unit. The microprocessor 400, which is capable of performing operations such as instruction fetch, instruction execution, and information exchange with external memory and logic components, is an operation control part of the microcomputer, and may constitute the microcomputer with a memory and a peripheral circuit chip.

The distance sensor 300 includes an optical sensor, an infrared sensor, and an ultrasonic sensor. The optical sensor includes a proximity light sensor. Distance sensor 300 is used for detecting the distance between main part 100 and the user's ear, when distance between earphone 10 and the user's ear is less than or equal to the preset distance, further adopt microprocessor 400 control respiration sensor 350 to gather user's breathing signal to the user's breathing signal who will gather compares with preset signal, when user's breathing signal and preset signal match, think that earphone 10 wears in user's ear, at this moment, can transmit sound to the user through earphone 10's speaker 200. Wherein, the value range of the preset distance can be 0-10 mm.

The manner of acquiring the respiratory signal of the user by the respiratory sensor 350 may be one-time acquisition or multiple-time acquisition. The process of collecting the respiratory signal of the user can be carried out synchronously with the process of comparing the respiratory signal with the preset signal, namely, the respiratory signal of the user is collected while the respiratory signal of the user is collected and compared with the preset signal, so that whether the earphone 10 is worn on the ear of the user is judged in real time, and the wearing detection timeliness is improved.

The earphone 10 that this application embodiment provided at first detects the distance between earphone 10 and the user's ear through distance sensor 300, works as when distance between earphone 10 and the user's ear is less than or equal to when predetermineeing the distance, microprocessor 400 control respiratory sensor 350 gathers user's respiratory signal, compares respiratory signal with predetermineeing the signal, works as respiratory signal with when predetermineeing the signal and match, microprocessor 400 judges earphone 10 is worn in user's ear to can be under the condition of wearing with user's ear, through speaker 200 output sound, improved earphone 10's application function.

Further, in an embodiment, the distance sensor 300 includes a first sensing element 310 and a second sensing element 320, the first sensing element 310 is mounted on the front surface of the main body 100, the second sensing element 320 is mounted on the back surface of the main body 100, the first sensing element 310 may be used for sensing whether the second sensing element 320 is shielded, and the second sensing element 320 may be used for sensing whether the first sensing element 310 is shielded. When the main body 100 is worn on the ear of the user, the front surface is attached to the inner wall of the ear of the user, at this time, the first sensing element 310 is shielded, and when the second sensing element 320 senses that the first sensing element 310 is shielded, the second sensing element 320 sends out the first signal, which indicates that the earphone 10 is primarily worn on the ear of the user. At this moment, further adopt microprocessor 400 to gather user's breathing signal, compare with preset signal through breathing signal to confirm whether earphone 10 is worn on user's ear, can enrich the function of earphone 10, and can reduce the risk of misjudgement.

In one embodiment, the microprocessor 400 is configured to compare waveform parameters of the respiration signal with waveform parameters of a preset signal, wherein the waveform parameters include at least one of frequency, amplitude and period.

The preset signal may be a breathing heart rate graph of the user under an ideal condition.

In an embodiment, the preset signal may be an ideal waveform obtained through multiple tests, and the preset signal refers to a waveform obtained when the user is in a stable state and has a good health condition.

In another embodiment, the preset signal may also be a waveform downloaded from a database of authorities to ensure that the acquired preset signal is in compliance with the standard specification.

In yet another embodiment, the preset signal may be a preset signal obtained after training through a neural network model. The method comprises the steps of obtaining a large number of breathing signals of users with different sexes, ages, heights and weights, inputting the obtained breathing signals into a neural network model, carrying out algorithm processing on the input breathing signals through data in a database, outputting results, and enabling the output results to be considered as ideal preset signals and to accord with relevant standards.

Further, the preset signal may be obtained by downloading in real time, or may be obtained by storing in advance. When the preset signal is acquired in a real-time downloading manner, the acquired preset signal can be a newly issued waveform diagram, that is, the acquired preset signal is a waveform diagram conforming to the latest standard. When the preset signal is obtained by pre-storing, the time consumed in the downloading process can be avoided, and the process of comparing the preset signal with the acquired breathing signal can be rapidly completed, so that the wearing detection timeliness of the earphone 10 is improved.

The respiratory signal of the user is compared with the preset signal, and the comparison index can be the conditions of comparing the frequency, the amplitude, the period and the like of the two oscillograms. And then feeds back to the microprocessor 400 in real time according to the comparison result, and then the microprocessor 400 indicates whether the earphone 10 is worn on the ear of the user according to the comparison result.

In another embodiment, the microprocessor 400 is further configured to determine whether the respiration signal has a periodic signal, and if the respiration signal has the periodic signal, the microprocessor 400 intercepts the periodic signal in the respiration signal and compares the intercepted periodic signal with the preset signal.

Specifically, the respiratory signal of a person in a calm state generates a certain fluctuation, and the respiratory signal of the person in the calm state should have a periodic characteristic. In order to accurately judge the breathing signal, in this embodiment, whether a periodic signal exists in the breathing signal is judged firstly, on the premise that the periodic signal exists in the breathing signal, the microprocessor 400 intercepts the periodic signal in the breathing signal, then compares the intercepted periodic signal with a preset signal, and because the periodic signal has accurate amplitude, phase, period and other parameters, the characteristic comparison can be performed more accurately, which is helpful for improving the accuracy of the comparison between the breathing signal and the preset signal, and further improves the accuracy of the wearing detection of the earphone 10.

Further, the microprocessor 400 segments the periodic signals according to the number of complete cycles of the periodic signals in the respiratory signals, compares all the respiratory signals after the segmentation with preset signals, and determines that the respiratory signals are matched with the preset signals when the comparison result is greater than a preset percentage, and at this time, the earphone 10 is considered to be worn on the ear of the user.

Furthermore, after the slicing processing is performed on the respiratory signals, signal amplification, filtering and noise reduction processing are performed on the respiratory signals, and then all the respiratory signals after the slicing processing are compared with preset signals.

In yet another embodiment, when the distance between the earphone 10 and the user's ear is greater than the preset distance and the speaker 200 is playing the first audio, the microprocessor 400 controls the speaker 200 to stop playing the first audio and controls the speaker 200 to play the second audio, which is used to indicate that the distance between the earphone 10 and the user's ear is greater than the preset distance.

The first audio is different from the second audio, the first audio is the audio currently being played by the speaker 200 of the earphone 10, and the first audio may be music. The second audio is used for giving out a prompt to the user. When the distance between the earphone 10 and the user is greater than the preset distance, the microprocessor 400 determines that the wearing between the earphone 10 and the ear of the user is in a problem, at this time, the microprocessor 400 controls the speaker 200 to play a second audio, and the second audio is used for indicating that the distance between the earphone 10 and the ear of the user is greater than the preset distance, so that the wearing between the earphone 10 and the ear of the user is considered to be required to be adjusted.

With continued reference to fig. 3 and 4, the earphone 10 further includes a motion sensor 360, the motion sensor 360 is further configured to detect a motion trajectory curve of the earphone 10, the microprocessor 400 compares the motion trajectory curve with a preset trajectory curve, and the respiration sensor 350 is controlled to acquire a respiration signal of the user when the motion trajectory curve is matched with the preset trajectory curve.

Wherein, the motion sensor 360 is used for detecting the motion track information of the earphone 10.

In one embodiment, the characteristic parameters of the motion trajectory curve are compared with the characteristic parameters of a preset trajectory curve, wherein the characteristic parameters include a starting point a, an end point B and an inflection point C of the curve.

Specifically, first, three feature points, i.e., a start point a, an inflection point C, and an end point B, are identified, and the motion trajectory curve of the headphone 10 in space is considered to be a planar curve. The motion trajectory curve of the earphone 10 in the space forms a coordinate sequence in the form of elements (time, x-axis coordinate and y-axis coordinate), and if the time when the user's finger touches the earphone 10 is t0 and the time when the user's finger leaves the earphone 10 is tn, the coordinates of a starting point are (t0, x0 and y0) and the coordinates of an ending point are (tn, xn and yn), and then the coordinates of an inflection point are identified. From time t0, a point is taken every 0.01 second, and from point 2, each point is compared with the previous point by the x-coordinate value. For convenience of description, let the x coordinates of any two adjacent points be: the former point is xx1 and the latter point is xx2, and the comparison of the first two points has the following three cases:

(1) if xx2 is xx1, no action is taken and the identification of the next point is continued. If xx2> xx1 and yy2> yy1 enters step (2), if xx2< xx1 and yy2< yy1 enters step (3), if xx2 ═ xx1, repeat step (1), and continue to identify the next point.

(2) If xx2> xx1 and yy2> yy1, then direction 1 is noted (representing that the motion trajectory curve of the headphone 10 in the space is an upward parabola, the user is considered to pick up the headphone 10), the next point is continuously identified, if xx2> xx1 or xx2 xx1, yy2> yy1 or yy2 yy1, the next point is continuously identified, if xx2< xx1 and yy2< yy1, the point is noted as inflection point xx0, and direction-1 is noted (representing that the motion trajectory curve of the headphone 10 in the space is an upward parabola, the user is considered to put down the headphone 10), and the next point is continuously identified. Continuing to identify the next point if xx2< xx1 or xx2 ═ xx1, yy2< yy1, or yy2 ═ yy 1; if xx2> xx1 and yy2> yy1, the motion profile recognition ends, indicating that the user is picking up the headset 10 at this time.

(3) If xx2< xx1 and yy2< yy1, then direction-1 is noted (representing that the motion trajectory curve of the headphone 10 in the space is a downward and upward parabola, the user is considered to put down the headphone 10), the next point is continuously identified, if xx2< xx1 or xx2 ═ xx1, yy2< yy1 or yy2 ═ yy1, the next point is continuously identified, if xx2> xx1 and yy2> yy1, the point is noted as inflection point xx0, and direction-1 is noted (representing that the motion trajectory curve of the headphone 10 in the space is an upward parabola, the user is considered to pick up the headphone 10), and the next point is continuously identified: continuing to identify the next point if xx2> xx1 or xx2 ═ xx1, yy2> yy1, or yy2 ═ yy 1; if xx2< xx1 and yy2< yy1, the motion profile recognition ends, indicating that the user is dropping the headphone 10 at this time.

Further, the microprocessor 400 compares the acquired motion trajectory curve of the earphone 10 with a preset trajectory curve, and determines whether the motion trajectory curve of the earphone 10 is matched with the preset trajectory curve, and under the condition that the motion trajectory curve of the earphone 10 is matched with the preset trajectory curve, the microprocessor 400 compares the breathing signal with a preset signal.

The preset track curve can be a standard curve for a user to take an article under normal conditions.

In an embodiment, the preset trajectory curve may be an ideal curve obtained through multiple tests, and the preset trajectory curve is a standard curve for taking an article when the arm of the user is bent normally.

In another embodiment, the preset trajectory curve may also be a graph downloaded from a database of authorities, thereby ensuring that the obtained preset trajectory curve is in compliance with the standard specification.

In yet another embodiment, the preset trajectory curve may be a trajectory curve obtained after training through a neural network model. The method comprises the steps of obtaining a large number of track curves of users with different sexes, different ages, different heights, left-right article taking and right-hand article taking, inputting the obtained track curves into a neural network model, carrying out algorithm processing on the input track curves through data in a database, outputting results, and enabling the output results to be regarded as track curves when normal people take articles and to be in accordance with relevant standards.

Further, the preset trajectory curve may be obtained by downloading in real time or may be obtained by storing in advance. When the preset trajectory curve is obtained in a real-time downloading manner, the obtained preset trajectory curve can be a newly issued curve, that is, the obtained preset trajectory curve is a curve conforming to the latest standard. When the preset track curve is obtained by pre-storing, the time consumed in the downloading process can be avoided, and the process of comparing the obtained motion track curve of the earphone 10 with the preset track curve can be rapidly completed, so that the wearing detection timeliness of the earphone 10 is improved.
