Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of wearable devices, and particularly relates to a signal output method and device of earphones. BACKGROUND

[0002] When playing stereo audio through earphones, a left-channel signal needs to be output to the earphone worn on the left ear, and a right-channel signal needs to be output to the earphone worn on the right ear, so as to ensure correct sound direction and accurate spatial sense, and improve the level and immersion of the output audio.

[0003] However, many earphones have the same structure on the left and right sides, so the left and right ears are often random when actually worn by the user. Once the channel output does not match the wearing position of the earphone, the sound direction will be disordered, seriously affecting the auditory experience. At this time, the user needs to manually adjust the wearing of the earphone so that the channel signal is output to the correct ear, but this way requires the user to manually operate to output the channel signal to the correct ear, and the process of matching the channels of the earphone is relatively cumbersome.

[0026] To address the aforementioned technical problems, this application provides a signal output method for headphones. The signal output method for headphones provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0027] like Figure 1 As shown, Figure 1 This is a flowchart illustrating a signal output method for headphones according to an embodiment of this application. This application provides a signal output method for headphones, which may include:

[0028] S101, when it is detected that the headphones are being worn, at least one of the acceleration and angular velocity of the headphones is obtained;

[0029] In this embodiment, the earphone can be an open-back wearable stereo (OWS) earphone. Since OWS earphones typically adopt an open-back structure, the structures of the left and right earphones are exactly the same and there are no obvious physical markings or differences. Therefore, it is difficult for users to determine which earphone is used for the left ear and which earphone is used for the right ear when wearing them.

[0030] Therefore, users can wear the earphones on either the left or right ear. Regardless of whether the user wears the earphones on the left or right ear, the earphones can detect that the user is wearing them. Once the earphones are detected to be wearing them, the acceleration and angular velocity of the earphones can be obtained.

[0031] Exemplarily, the earphone is provided with a 3-axis acceleration sensor and a 3-axis gyroscope sensor, wherein the acceleration sensor can measure acceleration data of the earphone in three axial directions, and the gyroscope sensor can measure angular velocity data of the earphone in three axial directions. When it is detected that the earphone is in a wearing state, the earphone can collect acceleration and angular velocity of the earphone at a certain frequency, and determine the wearing position of the earphone according to the acceleration and angular velocity of the earphone.

[0032] In S102, a wearing position of the earphone is determined according to at least one of the acceleration and the angular velocity, wherein the wearing position is a left ear position or a right ear position.

[0033] In the embodiment, after it is detected that the earphone is in a wearing state, the motion state of the earphone is affected by the user's head motion, so that the acceleration and angular velocity and the like of the earphone can reflect the motion state of the earphone, and the motion state of the user's head motion and the wearing position of the earphone can be analyzed based on the motion state of the earphone. For example, when the user nods or shakes his head, the earphones worn on the left ear and the right ear will generate different acceleration and rotation rate patterns. Therefore, in this way, the system can automatically identify whether the wearing position of the earphone is a left ear position or a right ear position according to the acceleration and angular velocity data, so as to perform corresponding channel switching.

[0034] In some embodiments, the determining of the wearing position of the earphone according to at least one of the acceleration and the angular velocity comprises:

[0035] determining whether the user performs a nodding action according to at least one of the acceleration and the angular velocity;

[0036] in a case that the user performs the nodding action, determining the wearing position of the earphone according to the nodding action.

[0037] In the embodiment, the acceleration and angular velocity of the user's head in different directions are different when the user's head performs different actions, and when the earphone is worn on the user's ear, the earphone and the user's head move simultaneously, so that the acceleration and angular velocity of the earphone can reflect the acceleration and angular velocity of the user's head in different directions, thereby determining whether the action of the user's head is a nodding action.

[0038] Exemplarily, when the user performs a nodding action, the user's head usually experiences a process of first lowering the head and then lifting the head, and no matter whether it is lowering the head or lifting the head, the action of the user's head can be regarded as rotating around a neck horizontal axis, which can be an axis line transversely parallel to the ground and located at the head-neck connection. When the user lowers or lifts the head, the user's head rotates forward and backward around the neck horizontal axis.

[0039] Specifically, when the user lowers or raises his head, the user's head rotates from an initial static state to gradually accelerate around the horizontal axis of the neck, and then gradually decelerate around the horizontal axis of the neck, to a final static state. If the acceleration and angular velocity of the earphone meet the above characteristics, it can be considered that the user has performed a nodding action.

[0040] However, in the process of the user performing the nodding action, since the user's head rotates first accelerates and then decelerates around the horizontal axis of the neck, the left ear and the right ear are on opposite sides of the rotation path, so when the earphone is worn on the left ear or the earphone is worn on the right ear, the earphone will feel acceleration and angular velocity changes in opposite directions; by identifying these directional differences, it can be determined whether the earphone is worn on the left ear or the right ear.

[0041] In this embodiment, it can be first identified whether the user has performed a nodding action, and if the user has performed a nodding action, the directional difference in acceleration or angular velocity of the left and right ears during the user's nodding can be further used to determine the wearing position of the earphone, so that the system can accurately identify the wearing position of the earphone without the need for manual operation by the user.

[0042] In some embodiments, the earphone includes a sound outlet and an ear handle connected to each other, the sound outlet has a sound outlet hole, the first direction is the positive direction of the y-axis in a target coordinate system, the target coordinate system is constructed based on the right-hand coordinate system rule and is associated with the earphone, and the target coordinate system takes the sound direction of the sound outlet hole of the earphone as the positive direction of the z-axis and takes the direction from the end of the ear handle away from the sound outlet to the end of the ear handle close to the sound outlet as the positive direction of the x-axis.

[0043] The determination of whether the user performs a nodding action according to the acceleration includes:

[0044] All accelerations of the earphone in the first direction within a first time period are greater than a first threshold value, the maximum acceleration within the first time period is greater than a second threshold value, and the duration of the first time period is greater than a first duration threshold value, it is determined that the user performs a first action within the first time period, wherein the first threshold value is greater than 0, and the second threshold value is greater than the first threshold value.

[0045] All accelerations of the earphone in the first direction within a second time period are less than a third threshold value, the minimum acceleration within the first time period is less than a fourth threshold value, and the duration of the second time period is greater than a second duration threshold value, it is determined that the user performs a second action within the second time period, wherein the third threshold value is less than 0, and the fourth threshold value is less than the third threshold value.

[0046] In a case that a time interval between a first time period in which the user performs the first action and a second time period in which the user performs the second action is less than a fifth threshold value, it is determined that the user performs a nodding action once in the first time period and the second time period.

[0047] In the embodiment, the earphone can be composed of two parts, a sound outlet part and an ear handle part, which are connected to each other. The sound outlet part includes a sound outlet hole for transmitting sound into the user's ear, and the ear handle part extends outward and can be used to place components such as a microphone and a battery, and facilitate the user to fix and wear the earphone.

[0048] In order to accurately identify the spatial posture and wearing direction of the earphone, a three-dimensional target coordinate system associated with the structure of the earphone can be defined. In the target coordinate system, the positive direction of the z-axis can be set as the sound outlet direction of the sound outlet hole of the earphone, the positive direction of the x-axis can be set as the direction of the ear handle from the end away from the sound outlet part to the end close to the sound outlet part, and the positive direction of the y-axis can be determined according to the right-hand coordinate system rule, that is, the y-axis is perpendicular to the x-axis and the z-axis. The positive direction of the y-axis of the target coordinate system can be determined as the first direction.

[0049] Then, when the earphone is worn on the left ear of the user, the first direction points to the rear of the user, and when the earphone is worn on the right ear, the first direction points to the front of the user. In this way, the acceleration of the earphone in the first direction can be used to determine whether the user performs a nodding action and whether the earphone is worn on the left ear or the right ear.

[0050] Since the nodding action of the user includes a lowering action and a lifting action, when the user performs a nodding action, no matter whether the user performs a lowering action or a lifting action, the earphone will rotate from an initial static state to gradually accelerate around the horizontal axis of the neck, then gradually decelerate around the horizontal axis of the neck, and finally reach a static state. In this process, the absolute value of the acceleration will first increase and then decrease, and only the directions of the acceleration in the lowering action and the lifting action are opposite.

[0051] Therefore, if it is detected that the acceleration of the earphone in the first direction in the first time period is greater than a first threshold value, it means that the earphone continuously accelerates in the first direction in the first time period. If the maximum acceleration in the first time period is greater than a larger second threshold value, it means that the maximum acceleration of the user in the first time period is large, and it is not a slight shaking but a relatively forceful lifting or lowering action. If the duration of the first time period is greater than a first duration threshold value, it can be considered that the duration of the first time period is relatively long, and the earphone is not a short and random acceleration disturbance.

[0052] Therefore, if the acceleration of the earphone in the first direction during the first time period is greater than the first threshold value, the maximum acceleration during the first time period is greater than the second threshold value, and the duration of the first time period is greater than the first duration threshold value, it means that the earphone in the wearing state has performed a complete and stable acceleration action in the first direction for a long time period, there is a stable and significant acceleration process during the first time period, and it tends to stop or decelerate at the end of the time period. Therefore, it can be considered that the user performs the first action during the first time period, and the first action can be a head-up action or a head-down action.

[0053] Similarly, if the acceleration of the earphone in the first direction during the second time period is less than the third threshold value, the minimum acceleration during the second time period is less than the fourth threshold value, and the duration of the second time period is greater than the second duration threshold value, it means that the earphone has performed a complete and stable acceleration action in the direction opposite to the first direction for a long time period, there is a stable and significant acceleration process during the second time period, and it tends to stop or decelerate at the end of the time period. Therefore, it can be considered that the user performs the second action during the second time period, and the second action can be a head-up action or a head-down action.

[0054] In addition, if the first action is a head-up action, the second action is a head-down action; if the second action is a head-down action, the first action is a head-up action.

[0055] In addition, if the time interval between the first action and the second action is less than the fifth threshold value, it means that the time interval between the head-down and head-up of the user is very close, and the first action and the second action can be collectively regarded as a nod action.

[0056] Exemplarily, Figure 2 and Figure 3 are waveform diagrams of the detected acceleration in the first direction changing with time. The points a-h in the waveform diagram are feature calculation points, p1 and p2 are peak points, v1 and v2 are valley points, r1 is the first threshold value, r2 is the third threshold value, t1-t4 are the durations of the wave peaks and wave troughs, and h1-h4 are the heights of the peaks and troughs.

[0057] The points in the waveform diagram can be traversed, and in the case that the feature point a is first detected to have an acceleration less than the third threshold value, the above process can be started. For example, Figure 2 and Figure 3As shown, the second time period is the time period between point a and point b, the duration of the second time period is t1, the acceleration of the earphone in the first direction in the second time period t1 is less than the third threshold r2, the minimum acceleration v1 in the second time period is less than the fourth threshold, and the duration of the second time period t1 is greater than the second duration threshold, which means that the earphone has a complete and stable acceleration action in the direction opposite to the first direction for a long time, there is a stable and significant acceleration process in the second time period, and it tends to stop or decelerate at the end of the time period. Therefore, it can be considered that the user performs the second action in the second time period.

[0058] Similarly, as shown in Figure 2 and Figure 3 After point b, when the feature point c is first detected, the acceleration is greater than the first threshold, then the first time period is the time period between point c and point d, the duration of the second time period is t2, the acceleration of the earphone in the first direction in the first time period t2 is greater than the first threshold r1, the maximum acceleration p1 in the first time period is greater than the second threshold, and the duration of the first time period t2 is greater than the first duration threshold, which means that the earphone has a complete and stable acceleration action in the first direction for a long time, there is a stable and significant acceleration process in the first time period, and it tends to stop or decelerate at the end of the time period. Therefore, it can be considered that the user performs the first action in the first time period.

[0059] And if the time interval between the first action and the second action is less than the fifth threshold, that is Figure 2 the time interval between b and c in the fifth threshold, it can be considered that the first action and the second action are close, and the first action and the second action can be determined as a nodding action together.

[0060] In the above manner, based on the acceleration direction, acceleration amplitude, and duration of the earphone in the wearing state, as well as the time interval of acceleration in different directions, the user's continuous actions of lowering and raising the head can be accurately recognized, and this judgment can be determined as a complete nodding behavior. Compared with the recognition method relying on single instantaneous acceleration, this scheme has stronger anti-interference and action recognition accuracy, can effectively reduce the misjudgment rate, and can more accurately recognize the user's nodding action.

[0061] In some embodiments, the first direction is the x-axis direction or the y-axis direction in a target coordinate system, the target coordinate system is a three-dimensional coordinate system constructed based on the right-hand coordinate system rule with the second direction as the z-axis, and the second direction is the direction in which the earphone shell points to the sound outlet of the earphone;

[0062] The determination of the wearing position of the earphone according to the nodding action comprises:

[0063] In the case that the first action is prior to the second action in the nodding action, the wearing position of the earphone is determined as the right ear of the user;

[0064] In the case that the second action is prior to the first action in the nodding action, the wearing position of the earphone is determined as the left ear of the user.

[0065] In the embodiment, for the user, when the earphone is worn on the left ear of the user, the first direction points to the rear of the user; when the earphone is worn on the right ear of the user, the first direction points to the front of the user, and in the process of the user lowering the head, the earphone accelerates forward and downward, and in the process of the user raising the head, the earphone accelerates upward and rearward.

[0066] Then, if the earphone is worn on the left ear of the user, when the user lowers the head and the earphone accelerates forward and downward, the direction of acceleration is opposite to the first direction, at this time, the user performs the second action; when the user raises the head and the earphone accelerates upward and rearward, the direction of acceleration is the same as the first direction, at this time, the user performs the first action, therefore, if the second action is performed prior to the first action in each nodding action, it can be determined that the earphone is worn on the left ear of the user.

[0067] Conversely, if the earphone is worn on the right ear of the user, the z-axis direction is the direction from the right of the user to the left of the user, correspondingly, the y-axis direction is the direction from the upper of the user to the lower of the user, and the x-axis direction is the direction from the rear of the user to the front of the user; that is, when the earphone is worn on the right ear of the user, for the user, the first direction can be the direction from the upper to the lower, or the direction from the rear to the front. In the process of the user lowering the head, the earphone accelerates forward and downward, and in the process of the user raising the head, the earphone accelerates upward and rearward.

[0068] Then, if the earphone is worn on the right ear of the user, when the user lowers the head and the earphone accelerates forward and downward, the direction of acceleration is the same as the first direction, at this time, the user performs the first action; when the user raises the head and the earphone accelerates upward and rearward, the direction of acceleration is opposite to the first direction, at this time, the user performs the second action, therefore, if the second action is performed prior to the first action in each nodding action, it can be determined that the earphone is worn on the right ear of the user.

[0069] In the above manner, the wearing position of the earphone can be accurately determined by analyzing the relative relationship between the acceleration and the first direction and the time sequence in the nodding action, so as to realize automatic channel switching and improve wearing convenience.

[0070] In addition, as mentioned above, since the nodding motion is essentially a forward and backward rotation of the head around the horizontal axis of the neck, the head will cause the earphone to have a positive and negative angular velocity fluctuation in the first direction during the process of lowering and raising the head, regardless of whether the earphone is worn on the left ear or the right ear. Therefore, the composition of the nodding motion can also be determined by judging the absolute value of the rotation angular velocity and the rotation direction. And further by the relationship between the rotation angular velocity and the first direction, and the sequence of the forward and backward motions, to determine the wearing position of the earphone.

[0071] S103, outputting a channel signal corresponding to the wearing position of the earphone according to the wearing position of the earphone.

[0072] In the embodiments of the present application, the channel signal refers to a certain specific direction of sound data stream for outputting audio content, and the channel signal includes a left channel signal and a right channel signal.

[0073] And because the human ear perceives the spatial position of sound through the difference in the direction of receiving sound by the left and right ears. Therefore, it is necessary to transmit the left channel signal to the left ear and the right channel signal to the right ear, so that the designed direction and stereo sense in the audio can be restored, allowing the user to accurately feel that the sound comes from the left or right, thereby improving the sense of hearing reality and immersion. If the left channel and the right channel are connected in reverse, the sound direction will be disordered, affecting the user's experience of listening to music, watching movies, playing games, etc. Therefore, in the case where it is detected that the wearing position of the earphone is the left ear of the user, the left channel signal needs to be output to the earphone; in the case where it is detected that the wearing position of the earphone is the right ear of the user, the right channel signal needs to be output to the earphone.

[0074] In the above manner, after detecting that the earphone is in the wearing state, at least one of the acceleration and the angular velocity of the earphone is obtained, and then it is automatically judged whether the wearing position of the earphone is the left ear or the right ear according to at least one of the acceleration and the angular velocity, and the corresponding channel signal is output accordingly. Compared with the related art in which the user manually adjusts the wearing position of the earphone so that the earphone outputs the channel signal corresponding to the ear, the present solution does not require manual operation of the user, and can automatically output the corresponding channel signal to different ears after the earphone is worn, thereby simplifying the process of matching the channel of the earphone.

[0075] In some embodiments, the method further comprises:

[0076] In a third time period after detecting that the earphone is in the wearing state, if the wearing position of the earphone is not identified, outputting a prompt information, the prompt information is used to prompt that the wearing position of the earphone cannot be detected.

[0077] In this embodiment, if the wearing position of the earphone cannot be recognized through the above manner, the earphone can play a prompt information, which can be a voice prompt such as "wearing position not recognized" or a specific prompt tone, to prompt the user that the wearing position of the earphone cannot be detected.

[0078] After hearing the prompt information, the user can manually select the wearing position of the earphone or slightly nod to re-trigger the identification process of the wearing position of the earphone.

[0079] In the above scheme, the prompt information can be output when the wearing position detection fails, so as to timely guide the user to adjust the wearing of the earphone or re-trigger the identification operation, and avoid continuously outputting the incorrect channel signal, thereby improving the fault tolerance and user experience of the system.

Compared with the related art in which the user manually adjusts the wearing position of the earphone so that the earphone outputs the channel signal corresponding to the ear, the present scheme does not require manual operation of the user, and can automatically output the corresponding channel signal to different ears after the earphone is worn, thereby simplifying the process of matching the channel of the earphone.
