Description

Technical Field

[0001] The present invention relates to the field of headphone control technology, and in particular to a TWS ear-hook headphone sound adjustment method, a control device, and a TWS ear-hook headphone. Background Art

[0002] Because of their non-insertion properties, ear-hook headphones allow users to wear them for long periods without feeling any ear canal pain. However, this brings a new problem: unlike in-ear headphones, the sound outlet of ear-hook headphones is not fixed in a certain position in the ear canal, but is located at any position close to the auricle. In addition, the user's wearing movements will be different each time, which will eventually cause the sound outlet of the headphones to be located in a different position on the auricle each time the headphones are worn. This will cause the user to hear different sound levels each time they use the ear-hook headphones multiple times, and they will need to repeatedly adjust the volume, which greatly affects the user experience.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0051] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field.

[0053] Because of their non-insertion properties, ear-hook headphones allow users to wear them for long periods without feeling any ear canal pain. However, this brings a new problem: unlike in-ear headphones, the sound outlet of ear-hook headphones is not fixed in a certain position in the ear canal, but is located at any position close to the auricle. In addition, the user's wearing movements will be different each time, which will eventually cause the sound outlet of the headphones to be located in a different position on the auricle each time the headphones are worn. This will cause the user to hear different sound levels each time they use the ear-hook headphones multiple times, and they will need to repeatedly adjust the volume, which greatly affects the user experience.

[0054] To this end, the present invention proposes a volume adjustment method for TWS ear-hook headphones. The TWS ear-hook headphones have an earphone body, a Bluetooth communication module is arranged in the earphone body, the earphone body includes a fixed part and a sound output part provided with a sound outlet, the sound output part and the fixed part are connected by an elastic part, and under the action of the elastic part, the sound output part and the fixed part can be maintained in a first position in contact with each other; when the user wears the TWS ear-hook headphones, the sound output part and the fixed part are arranged close to each other under the action of the elastic part so that the earphone body is hung on the auricle and the sound output part is arranged in contact with the concha cavity inside the auricle.

[0055] It is important to understand that due to the structural characteristics of in-ear headphones, the sound outlet of the in-ear headphones is located in a relatively fixed position within the external auditory canal each time the user wears the headphones. Therefore, as long as the external terminal and the volume of the external terminal remain unchanged, the sound the user actually hears will not differ significantly each time the user wears the in-ear headphones to listen to music. In other words, each time the user wears the in-ear headphones and plays music through the external terminal, as long as it is the same external terminal, the user usually does not adjust the volume of the external terminal this time, and can listen to music according to the external terminal volume set when the external terminal was last connected.

[0056] However, for Figure 2 and Figure 3 For the ear-hook earphones shown in , since the ear-hook earphones are clamped on the auricle by the sound-emitting part and the fixing part by an elastic part, it is difficult to say that the position of the earphones on the auricle is the same every time the user wears them. In other words, for the sound-emitting part, when the ear-hook earphones are worn multiple times, the fit with different positions on the concha cavity will be different each time. Then, when the user actually listens to the sound, due to the different positions of the sound-emitting part, the position of the sound outlet relative to the external auditory canal will also be different. Then, the volume of the sound heard by the user each time when wearing the ear-hook earphones will also be different. This makes the user need to adjust the volume of the external terminal to the appropriate volume each time using the ear-hook earphones, which is very troublesome. Therefore, the following TWS ear-hook earphone volume adjustment method of this application is to improve the above situation and improve the convenience of the user.

[0057] In this embodiment, the earphones are provided with a control device for storing and executing the following method. The control device can be implemented by a main controller, such as an MCU (Microcontroller Unit), a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), a SOC (System On Chip), etc. At the same time, the earphones are provided with a Bluetooth communication module for communicating with an external terminal, and a speaker and a sound processing module are provided in the sound output portion. The control device obtains the audio output from the external terminal through the Bluetooth communication module and then plays it from the sound outlet through the sound processing module and the speaker. For example, the audio signal is filtered, digital-to-analog converted, frequency modulated, etc. by the sound processing module and then played from the sound outlet through the speaker. Reference Figure 2 When the user is not wearing the earphones, the sound outlet and the fixing portion are able to maintain contact with each other in the first position under the action of the elastic portion. When the user needs to wear the earphones, the user applies force to separate the contacting sound outlet and fixing portion, and then places the sound outlet on the concha of the auricle and the fixing portion on the back of the auricle. In this way, under the action of the elastic portion, the sound outlet and fixing portion clamp the auricle, so that the earphones are hung on the user's auricle.

[0058] refer to Figure 1 and Figure 2 In one embodiment of the present invention, the TWS earphone volume adjustment method includes:

[0059] Step S100: The earphone obtains its wearing status;

[0060] In this embodiment, optionally, the wearing detection of the ear-hanging headphones can be achieved by optical detection. For example, an optical transceiver is provided in the sound output part and is electrically connected to the control device. When the user wears the ear-hanging headphones, the optical receiver can receive the optical signal emitted by the optical transmitter that is reflected through the user's auricle. When the control device determines the result, it will confirm that the user has put on the headphones.

[0061] Optionally, refer to Figure 3 In another embodiment, the elastic portion has a first side and a second side disposed opposite to each other. When a user wears the TWS earphones, the first side of the elastic portion is disposed in contact with the user's auricle. The earphone body is further provided with a capacitive touch detection module and an electrode detection area electrically connected to the capacitive touch detection module, and the electrode detection area is disposed on the first side.

[0062] The step S100, in which the earphone obtains its own wearing status, includes:

[0063] Step S110: acquiring the capacitance value of the electrode detection area detected by the capacitive touch detection module;

[0064] Step S120: When the capacitance value of the electrode detection area reaches a preset capacitance value, the ear-hook earphone determines that it is in a worn state; when the capacitance value of the electrode detection area does not reach the preset capacitance value, the ear-hook earphone determines that it is not in a worn state.

[0065] In this embodiment, the capacitive touch detection module can be implemented using a capacitive detection chip and its peripheral circuits, and the electrode detection area can be implemented using an electrode sheet. When the user wears the earphones, the auricle will contact the first side of the elastic portion, thereby fitting with the electrode detection area, which will cause the capacitance value of the electrode detection area to increase. Therefore, based on the detection results of the capacitive touch detection module, the control device determines that the earphones are in the worn state if the capacitance value of the electrode detection area reaches a preset capacitance value; if the capacitance value of the electrode detection area does not reach the preset capacitance value, the control device determines that the earphones are not in the worn state.

[0066] Step S200: The earphone obtains its own posture information when determining that the earphone is in a worn state and establishing a wireless communication connection with an external terminal via the Bluetooth communication module;

[0067] Step S300: Based on the posture information of the device, the volume of the external terminal is adjusted to a corresponding target volume via the Bluetooth communication module.

[0068] In this embodiment, if the earphones are not connected to the external terminal via the Bluetooth communication module, it means that the user may not be using the earphones to listen to the audio pushed by the external terminal but just wants to wear the earphones. Therefore, the control device within the earphones will not determine its own posture information to reduce power consumption. If the earphones determine that they are being worn and establish a wireless communication connection with the external terminal via the Bluetooth communication module, the control device within the earphones will obtain the earphones' own posture information.

[0069] Optionally, in one embodiment, referring to Figure 4 , a tilt angle sensor is provided in the sound output portion; in step S200, when the earphone determines that the earphone is in a worn state and establishes a wireless communication connection with an external terminal via the Bluetooth communication module, obtaining its own posture information includes:

[0070] Step S210: When the earphone is determined to be in a worn state and a wireless communication connection is established with an external terminal via the Bluetooth communication module, the earphone obtains an inclination angle of the sound output portion relative to a horizontal plane via the inclination angle sensor;

[0071] Step S220: according to the tilt angle, taking the tilt angle that remains unchanged within a preset second time period as a target tilt angle;

[0072] The step S300, controlling the volume of the external terminal to be adjusted to a corresponding target volume via the Bluetooth communication module based on the posture information thereof, includes:

[0073] Step S310: Based on the target tilt angle, the Bluetooth communication module controls the volume of the external terminal to be adjusted to a target volume corresponding to the target tilt angle.

[0074] In this embodiment, the tilt angle sensor can be implemented by an accelerometer, a gyroscope, etc. When the control device determines that the ear-hook earphones are in a worn state and a wireless communication connection is established with an external terminal via the Bluetooth communication module, the control device obtains the tilt angle of the sound output part relative to the horizontal plane via the tilt angle sensor. It can be understood that since the sound outlet is provided on the sound outlet, and different wearing methods of the ear-hook earphones will cause the tilt angle of the sound output part relative to the horizontal plane to be different, thereby affecting the position of the sound outlet and the actual sound effect. Therefore, setting the tilt angle of the sound output part relative to the horizontal plane as posture information helps to improve the accuracy of subsequent volume adjustment. Then, if the control device determines that the tilt angle remains unchanged within a preset second time period (preset by R&D personnel), it can be determined that the current user has worn the earphones stably, and the above-mentioned tilt angle that remains unchanged will be used as the target tilt angle.

[0075] Furthermore, the step S220 includes, based on the tilt angle, taking the tilt angle that remains unchanged within a preset second time period as a target tilt angle;

[0076] If the earphones are switched from a non-worn state to a worn state, after the preset first time period of switching to the worn state, the tilt angle maintained within a preset second time period is used as the target tilt angle; wherein the preset second time period is less than the preset first time period;

[0077] If the earphones are worn for a third time, the tilt angle that remains unchanged during the second time is used as the target tilt angle; wherein the third time is greater than the first time.

[0078] In this embodiment, since the user will adjust the position of the earphones several times when they first put on them, in order to reduce the complexity of the tilt angle detection, the control device does not determine the target tilt angle based on the tilt angle during the preset first time period when the earphones are determined to be switched from the unworn state to the worn state through the process of the above embodiment. Instead, after the preset first time period, the tilt angle that remains unchanged during the preset second time period is used as the target tilt angle. At the same time, since the user will basically not move the earphones again after properly adjusting them when they first put them on, the preset second time period can be shorter than the preset first time period, thereby increasing the speed of determining the target tilt angle.

[0079] In this embodiment, reference Figure 6 The step S310, based on the target tilt angle, controlling the volume of the external terminal to be adjusted to a target volume corresponding to the target tilt angle via the Bluetooth communication module, includes:

[0080] Step S311: The earphone communicates with the external terminal via the Bluetooth communication module to obtain a tilt angle-target volume transfer function stored in the external terminal;

[0081] Step S312: Based on the target tilt angle, the target volume is determined according to the tilt angle-target volume transfer function, and the volume of the external terminal is controlled by the Bluetooth communication module to be adjusted to the corresponding target volume.

[0082] In this embodiment, the control device in the ear-hook headphones communicates with the external terminal via the Bluetooth communication module to obtain the previously stored corresponding tilt angle-target volume transfer function from the external terminal. The tilt angle-target volume transfer function can be calibrated and stored by the user when the ear-hook headphones are used for the first time, or pre-stored by R&D personnel and stored in the cloud. After the control device determines the final target tilt angle through the process of the above embodiment, it will substitute the tilt angle-target volume transfer function, calculate the target volume, and adjust the volume of the external terminal controlled by the Bluetooth communication module to the corresponding target volume.

[0083] In summary, through the above settings, the ear-hook headphones proposed in this application will autonomously identify the posture of their own sound-emitting part after being put on by the user, and then control the external terminal to adjust the volume to the corresponding target volume according to the posture, so that when the user wears the ear-hook headphones in different wearing methods, the sound volume heard from the sound outlet of the headphones is close. Compared with the existing technology, the present application can improve the situation where the user has to adjust the volume of the external terminal every time when using the ear-hook headphones to listen to music, reduce the number of times the user adjusts the volume every time when wearing the headphones to listen to music, and effectively improve the convenience of using the ear-hook headphones and the user experience.

[0084] It should be understood that different models of external terminals have different audio signal push capabilities and volume settings. For example, the actual sound output of the same volume may be different between different models of mobile phones. Therefore, in order to ensure the accuracy of the sound output, if the earphones do not obtain the stored tilt angle-target volume transfer function in the external terminal, it means that for the external terminal, the earphones are communicating with it for the first time in history. In this case, the earphones need to calibrate the volume of the external terminal to ensure the accuracy of the volume adjustment.

[0085] To this end, in one embodiment of the present application, refer to Figure 7-Figure 8 and Figure 9 Before the step S310, based on the target tilt angle, controlling the volume of the external terminal to be adjusted to a target volume corresponding to the target tilt angle via the Bluetooth communication module, the method further includes:

[0086] Step S410: When the ear-hook headset communicates with the external terminal via the Bluetooth communication module and determines that the external terminal does not store the tilt angle-target volume transfer function, the ear-hook headset controls the external terminal to display a volume calibration request;

[0087] Step S420: When the earphone receives a volume calibration consent instruction from the external terminal, obtain multiple wearing methods arranged in a first order, and set the first wearing method in the first order as a target wearing method; wherein the multiple wearing methods include: the earphone is hung on the lower part of the auricle, the earphone is hung on the middle part of the auricle, the earphone is hung on the upper-middle part of the auricle, and the earphone is hung on the upper part of the auricle;

[0088] Step S430: Control the external terminal to display the current target wearing method and instruct the user to wear the earphones according to the target wearing method;

[0089] Step S440: When the ear-hook headset receives the wearing completion instruction from the external terminal, the external terminal is controlled to play the calibration music through the ear-hook headset, and the external terminal is controlled to instruct the user to adjust the required volume;

[0090] Step S450: When the earphone receives a volume setting completion instruction from the external terminal, obtaining a current tilt angle of the sound output portion and using it as a calibration tilt angle, obtaining a current volume of the external terminal and using it as a calibration volume, and matching the calibration tilt angle and the calibration volume to form a set of calibration data;

[0091] Step S460: setting the next wearing mode after the current wearing mode as a new target wearing mode according to the first order and repeating steps S430-S460 until all wearing modes are used as target wearing modes;

[0092] Step S470: Generate the tilt angle-target volume transfer function according to the multiple sets of calibration data and store it in an external terminal.

[0093] In this embodiment, after the control device in the ear-hook headset establishes a communication connection with the external terminal, if it is found that the corresponding APP in the current external terminal does not store the tilt angle-target volume transfer function corresponding to the external terminal, then the control device will confirm that the current external terminal is communicating with the ear-hook headset for the first time in history, and then will control the APP on the external terminal to display a volume calibration request.

[0094] When the user operates the external terminal to agree to perform volume calibration, the external terminal will output a volume calibration consent instruction to the control device. When the control device receives the instruction, it will use the first wearing method among multiple wearing methods as the target wearing method according to the first order (preset by the R&D personnel) and control the APP on the external terminal to display it. For example, refer to Figure 9 , the control device will first control the external terminal to display an image of the corresponding ear-hook earphone hanging on the lower part of the auricle in the form of a picture, and then provide a text prompt to inform the user to wear the earphones as shown in the picture. After the user wears the earphones as shown in the picture, the external terminal will be operated to make the external terminal output a wearing completion instruction to the control device. After receiving the wearing completion instruction, the control device will control the external terminal to play the calibration music through the ear-hook earphones, and control the external terminal to instruct the user to adjust the required volume. For example, the text "Please adjust the volume to the volume that you feel most comfortable with and press the volume setting completion icon after adjustment" is displayed. Among them, the calibration music can be the preset music obtained by the APP on the external terminal from the manufacturer's server of the ear-hook earphones, or the user can set the audio stored in the external terminal as the calibration music.

[0095] After the user adjusts the volume of the external terminal to an appropriate volume and triggers the volume setting completion icon, the control device in the earphones will obtain the volume setting completion instruction from the external terminal. Then, the inclination angle of the current sound output part is determined through the process of the above embodiment, and it is recorded as the calibration inclination angle. At the same time, the current volume is obtained from the external terminal as the calibration volume, and the calibration inclination angle and the calibration volume are matched into a set of calibration data. After this set of data is obtained, the image corresponding to the next wearing method will be displayed in the first order and the above calibration process will be repeated to obtain a set of calibration data corresponding to each wearing method. For example, in the first order, the images corresponding to the next wearing method will be displayed in sequence. Figure 9The image corresponding to each wearing method is obtained, and a set of calibration data corresponding to each wearing method is obtained.

[0096] After obtaining the calibration data corresponding to all wearing methods in the first order, the control device will generate the tilt angle-target volume transfer function based on multiple sets of the calibration data and store it in the external terminal. In this way, for the user and the external terminal used by the earphones, when the earphones first establish a communication connection with the external terminal, they can generate a tilt angle-target volume transfer function that matches the user and the external terminal. Then, in the subsequent volume adjustment process, the target volume can be more accurately adjusted to the volume required by the user, further improving the user experience.

[0097] Furthermore, it is understandable that the external shapes of the ears, and in particular the external shapes of the auricles, vary for different users. Therefore, users generally have their own preferred wearing styles, and the multiple wearing styles indicated above may not necessarily meet their needs. Therefore, in one embodiment, between steps S460 and S470, the method further includes: setting any wearing style as the target wearing style, and executing steps S430-S460.

[0098] In this embodiment, the control device controls the APP on the external terminal to display the currently required wearing method as any wearing method, for example, displaying "Please wear the headphones in the way you like", and then, upon receiving the wearing completion instruction, performs the same process as above to obtain the user's favorite calibration tilt angle and the volume corresponding to the calibration tilt angle, and uses it as calibration data, so that the final generated tilt angle-target volume transfer function is more in line with the user's habits, thereby further improving the user experience and convenience.

[0099] It should be understood that in actual use, at a certain tilt angle, there may be a certain gap between the target volume determined through the above embodiment and the target volume actually required by the user.

[0100] To this end, in one embodiment of the present application, refer to Figure 10 After step S300, the method further includes:

[0101] Step S500: Acquire the audio from the external terminal and play it through the audio output unit;

[0102] Step S600: For a target tilt angle of any sound output portion, when audio is first played through the sound output portion and within a preset fourth time period after the playback, if the target volume is adjusted to a preset first number of times, then the target tilt angle is set as the tilt angle to be adjusted;

[0103] Step S700: Modify the tilt angle-target volume transfer function based on the tilt angle to be adjusted and the adjustment volume, so that the target volume calculated according to the modified tilt angle-target volume transfer function when the target tilt angle is the tilt angle to be adjusted is the adjustment volume.

[0104] In this embodiment, as can be seen from the above, after the control device sets the volume of the external terminal to the target volume via the Bluetooth communication module, the user operates the external terminal or the trigger on the earphone to cause the external terminal to output audio to the earphone. The control device then plays the audio received from the external terminal via the Bluetooth communication module through the internal power amplifier module from the sound output unit.

[0105] It is understandable that during the process of establishing a communication connection between the earphones and the external terminal, if the user is dissatisfied with the currently set target volume after the audio is played for the first time through the sound output part, then the user will inevitably operate the external terminal or the earphones within a short period of time (i.e., within the fourth time period preset by the R&D personnel) to change the current volume of the external terminal. Therefore, for the target tilt angle of any sound output part, within the preset fourth time period after the first sound is played during the communication process between the earphones and the external terminal, if the target volume is changed by the user to an adjusted volume, the control device will record the target tilt angle and the adjusted volume. If the above situation occurs during multiple communication processes between the earphones and the external terminal, that is, for the target tilt angle, the number of times the above record occurs reaches the preset first number (preset by the R&D personnel), the control device can determine that, for the target tilt angle, the target volume obtained through the above process is not suitable and needs to be modified, and will use the target tilt angle as the tilt angle to be adjusted.

[0106] Then, the control device modifies the tilt angle-target volume transfer function based on the tilt angle to be adjusted and the adjustment volume, so that the target volume calculated according to the modified tilt angle-target volume transfer function for the target tilt angle to be adjusted is the adjustment volume.

[0107] For example, if the target tilt angle is -20° and the target volume is originally set at 20%, but the user adjusts the volume of the external terminal to 30% shortly after playing audio for the first time while using the earphones to communicate with an external terminal, the control device will record the values ​​of -20° and 30% once. If the same data record occurs a preset number of times, the control device will use the data set of -20° tilt angle and 30% volume to adjust the tilt angle-target volume transfer function. This way, the next time the user uses the earphones to establish a communication connection with an external terminal, if the target tilt angle is still -20°, the volume of the external terminal will be automatically adjusted to 30%.

[0108] Through the above settings, the ear-hook headphones can autonomously learn the user's volume requirements and adaptively adjust the volume control execution, further improving the intelligence of the ear-hook headphones and enhancing the user experience.

[0109] The present invention also proposes a control device, which includes: a memory, a processor, and a TWS ear-hook headphone volume adjustment program stored on the memory and runnable on the processor, wherein the TWS ear-hook headphone volume adjustment program is configured to implement the TWS ear-hook headphone volume adjustment method as described in any one of the above items.
