Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The following exemplary described embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.
The existing headset can be manually adjusted to enable the headset to be attached to the ear of a user after the user wears the headset. However, the flexible protective layer is disposed outside the earphone, so that the user cannot perceive that the head of the earphone is completely attached to the ear, and the user feels tight while loose. Or, during the use, the user may move and the fit between the earphone and the ear may be tight and loose. If the sound waves are tight and loose, the center point of the sound waves emitted by the speaker may be deviated from the ear canal, i.e., the power of the audio entering the ear canal is reduced, which may cause the hearing to be degraded.
Fig. 1 is a flow chart illustrating an earphone control method according to an exemplary embodiment, which is suitable for the headset shown in fig. 2. Referring to fig. 2, the headset includes a headband 1 and a head 2, and further includes a plurality of pressure sensors 3, each of which is disposed at a predetermined position, and a first driving assembly for controlling the orientation of the head of the headset and a second driving assembly (not shown) for adjusting the orientation of a speaker.
It should be noted that the headset further includes a plurality of sensing devices, each of the sensing devices is set to a corresponding preset position, and is used to obtain sensing data about the ear, and the sensing data is used to determine whether the center of the speaker is aligned with the center of the ear on which the headset is worn. In an example, the plurality of sensing devices are pressure sensors, each of which may collect a pressure value between a preset position of the headset head and the ear. In another example, the plurality of sensing devices may be ultrasonic receivers, each for receiving an ultrasonic audio signal returned by the ear. The function of the pressure value and the ultrasonic audio signal will be described in the following embodiments.
It should be noted that the number of the pressure sensors may be set according to a specific scenario, for example, the headset may be provided with 4 pressure sensors, wherein 2 pressure sensors are respectively disposed on a straight line intersecting a plane where the head of the headset is located and a plane where the headband is located, and the other 2 pressure sensors may be disposed at symmetrical positions with respect to the plane where the headband is located, or the head of the headset is an elliptical component, and one pressure sensor is disposed at each of vertex positions of a major axis and a minor axis of the elliptical component. Similarly, the number of the ultrasonic receivers can be set according to a specific scene, and the specific number and the setting mode can refer to the related art, which is not described in detail herein. It should be noted that the number of the first driving assemblies may be set according to a specific scenario. For example, the driving assembly is implemented by 2 stepping motors, wherein 1 stepping motor is used for driving the headset head to rotate around the headband as an axis, the rotation direction is the direction R1 shown in fig. 2, and at this time, the front and back fit pressure of the headset head and the ear can be adjusted; the other 1 stepping motor is used for driving the earphone head to rotate around a fixed shaft vertical to the headband, and the rotating direction is shown as a direction R2 in fig. 2, so that the upper and lower attaching pressure of the earphone head and the ear can be adjusted. The number of second driving assemblies can be set according to a specific scenario, for example, 1 step motor is provided, so that the speaker in the earphone can move around the central axis of the speaker, and the rotation direction is the direction R3 shown in fig. 2.
Referring to fig. 1, a headphone control method includes steps 11 and 12, wherein:
in step 11, it is determined whether the center of the speaker is aligned with the center of the ear wearing the headphone.
In this embodiment, the processor in the headset may acquire whether the speaker center is aligned with the center of the ear, including:
in an example, when the headset is worn, the headset may be tight and loose, and the audio signal emitted by the speaker is no longer parallel to the ear canal due to a certain included angle formed between the plane of the headset head or the plane of the speaker surface and the plane of the ear, that is, the audio signal cannot be directly incident into the ear canal. Thus, referring to fig. 3, in step 31, the processor in the headset may obtain the pressure values collected by the pressure sensors. For example, each pressure sensor in the headset collects a pressure value according to a set period, and the pressure value is used for representing the pressure between the head of the headset and the head of the headset when the headset is worn and fitted. The processor in the headset can be connected with each pressure sensor to acquire the pressure value acquired by the pressure sensor, and the acquisition mode comprises receiving the pressure value reported by the pressure sensor or reading the pressure value from a local memory. In step 32, a preset threshold value of each pressure sensor may be stored in the headset in advance, and in practical applications, the preset threshold value may be set according to the installation position of each pressure sensor, for example, the preset threshold value of the pressure sensor in the front position (close to the face of the user) of the left channel headset in the headset may be larger than the preset threshold value of the pressure sensor in the rear position (close to the back brain of the user) because the headset is usually tilted forward during wearing. After the processor obtains the pressure values of the pressure sensors, the pressure values and the corresponding preset threshold values can be compared; determining that a center of the speaker is misaligned with a center of an ear wearing the headset when a pressure value of the at least one pressure sensor is less than a corresponding preset threshold value; when the pressure values of all the pressure sensors exceed the corresponding preset threshold values, it is determined that the center of the speaker is aligned with the center of the ear on which the headphone is worn.
In another example, the headset may have an ultrasonic receiver at a predetermined location, and the processor may control the speaker to emit an ultrasonic audio signal that returns to form an ultrasonic audio signal upon encountering an inner wall of the pinna, ear canal, and/or eardrum. Thus, the ultrasonic receiver can receive the ultrasonic audio signal. Referring to fig. 4, in step 41, the processor may acquire feature data of the ear wearing the headset based on the received ultrasonic audio signal. For example, the processor may sequentially acquire the location of the reflection point in the ear canal corresponding to the ultrasonic audio signal received by each ultrasonic receiver. The processor may then construct a 3D image of the ear based on the mounting location of the ultrasonic transmitter and the corresponding reflection point location for each ultrasonic audio signal. The method for constructing the 3D image may refer to related technologies, and is not described herein again.
The processor may obtain the characteristic parameter values of a preset number of designated positions on the 3D image, respectively. The characteristic parameter values may include a distance between a designated position and the ultrasonic transmitter, and a curvature (or a slope) of the designated position, and may be selected according to a specific scene. In addition, the number and the positions of the designated positions can be set according to specific scenes, for example, more positions can be designated on the protruded positions in the auditory canal, and less positions can be designated on the straighter positions, namely, the designated positions select the turning positions in the auditory canal as much as possible. The processor can construct a feature matrix of the 3D image according to the feature parameter values of the preset number of designated positions, and the feature matrix is used as feature data of the ear.
It will be appreciated that where the specified locations and the values of the characteristic parameters for each of the specified locations are known, a multi-dimensional matrix of characteristic parameter values can be formed in the order of the specified locations. For example, position 1 is specified, with the characteristic parameter values { x11, x12, x13 }; specifying the position 2, the characteristic parameter values { x21, x22, x23}, … …, specifying the position n, and the characteristic parameter values { xn1, xn2, xn3}, then obtaining the characteristic data as:
in another example, the processor may acquire spatial coordinates of a preset number of designated positions on the 3D image, respectively. For each designated position, the processor may obtain a distance between the designated position and each other designated position, and obtain a distance set corresponding to the designated position. And constructing a feature matrix of the 3D image according to each designated position and the distance set corresponding to the designated position, and taking the feature matrix as feature data of the ear.
Taking 4 designated positions as an example, the distance set corresponding to the designated position 1 is { x11, x12, x13, x14 }; the distance set corresponding to the designated position 2 is { x21, x22, x23, x24}, the distance set corresponding to the designated position 3 is { x31, x32, x33, x34}, the distance set corresponding to the designated position 4 is { x41, x42, x43, x44}, and the obtained ear feature data is:
and when the designated position coincides with the self position, the value is 0, and if x22 is zero.
In practical applications, the headset may have stored therein characteristic data of a predetermined ear. For example, the headset may transmit ultrasonic waves to acquire ear feature data after the headset is worn by a user, and the ear feature data is used as the ear feature data of the preset ear. For another example, when configuring the headset, the user is guided to perform corresponding configuration operations, and when the user determines that the audio listening effect is good, the feature data is acquired as the feature data of the preset ear.
In step 42, the processor may obtain the feature data of the ear and the cosine value of the feature data of the preset ear based on the feature data of the preset ear, and use the cosine value as the similarity between the ear and the preset ear. The cosine value may be calculated by referring to the related art, which is not described herein again.
In step 43, the processor obtains a preset similarity threshold, compares the similarity with the preset similarity threshold, and determines that the center of the speaker of the headset is aligned with the center of the entrance of the ear canal when the similarity exceeds the preset similarity threshold; determining that a center of a speaker of the headset is misaligned with an entrance center of the ear canal when the similarity is less than the preset threshold.
That is, whether or not a partial reflection point of the ear is not detected is determined by determining the similarity of the ear with a preset ear through the ultrasonic audio signal, so that it can be determined whether or not the headphone is tilted.
In step 12, when it is determined that the center of the speaker is not aligned with the center of the ear on which the headphone is worn, the center of the speaker is aligned with the center of the ear.
In this embodiment, when the processor determines that the center of the speaker is not aligned with the center of the ear, the aligning the center of the speaker with the center of the ear may include:
in an example, the orientation of the head of the headset is adjusted. The processor may control the first drive assembly to adjust the orientation of the headset, for example, to adjust the headset head tilt angle back and forth and/or tilt angle up and down, etc., until the pressure values of all the pressure sensors stop exceeding the corresponding preset thresholds to align the centers of the speakers with the centers of the ears.
In another example, the orientation of the speaker is adjusted. The processor may control the second driving means to adjust the orientation of the speaker such that the center of the speaker is directed towards the center of the ear canal, i.e. to align the center of the speaker towards the center of the ear canal. Therefore, the audio signal can be directly incident into the auditory canal, the attenuation of the audio signal is reduced, and the effect of listening to the audio is ensured.
To this end, in the embodiments of the present disclosure, it may be determined whether the center of the speaker is aligned with the center of the ear on which the headphone is worn; when it is determined that the center of the speaker is not aligned with the center of the ear on which the headphone is worn, the center of the speaker is aligned with the center of the ear. Like this, through the center of aligning speaker center and ear in this embodiment, can guarantee to get into the audio signal's of duct power, guarantee to listen to the effect of audio frequency, be favorable to promoting user experience.
