"And / or" describes the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0053] Figure 1 This is an application scenario diagram of an audio output method for a sofa provided in an embodiment of the present application. Figure 1 As shown, the audio output method of the sofa can be applied to the sofa 110, and the sofa 110 can establish a communication connection with the hearing aid device 120. The sofa 110 may include an audio output module 112, which can be built inside the sofa 110 or independent of the sofa 110 and communicated with the processor in the sofa 110.

[0054] The sofa 110 can be a fabric sofa, a leather sofa, a solid wood sofa, etc., which are classified by material; it can also be an ordinary sofa, a multifunctional sofa (such as a sofa that can be converted into a bed, etc.), a massage sofa, etc., which are classified by function; it can also be a straight sofa, a corner sofa, a U-shaped sofa, etc., which are classified by shape. No specific limitation is made here. It is only necessary that the sofa 110 has a communication connection function and has a built-in or external audio output module 112.

[0055] The hearing aid device 120 is a device used to improve or enhance hearing ability. Such devices are usually used to amplify relatively weak sounds so that the user can hear the relatively weak sounds. The hearing aid device 120 can be a hearing aid classified by conduction method, such as an air conduction hearing aid and a bone conduction hearing aid, or a hearing aid classified by usage method, such as a behind-the-ear hearing aid, an in-the-ear hearing aid, and an ear canal hearing aid. No specific limitation is made here, and the hearing aid device 120 only needs to have a communication connection function.

[0056] The audio output module 112 refers to a device that can be used to output audio data and implement an audio playback function. The audio output module 112 may include a speaker, a sound box, etc., which is not specifically limited here.

[0057] The communication connection established between the sofa 110 and the hearing aid device 120 may be a wireless communication connection, which includes but is not limited to a wireless fidelity (WIFI) communication connection technology, a cellular network connection, a Bluetooth communication connection, etc. Through the communication connection between the sofa 110 and the hearing aid device 120, information exchange can be performed between the sofa 110 and the hearing aid device 120.

[0058] Audio data refers to the digital audio data that is converted from analog audio data by the sound input device after analog-to-digital conversion. The playback of audio data is to convert the digital sound data into analog audio data for output.

[0059] The hearing aid device 120 can detect by itself whether it is in a wearing state. The wearing state refers to a state in which the user fits the hearing aid device to the ear and can receive audio data output by the hearing aid device.

[0060] Exemplarily, the audio output module 112 is taken as an example of a built-in speaker of the sofa 110. When the sofa 110 successfully establishes a communication connection with the hearing aid device 120, the sofa 110 can receive a first confirmation signal sent by the hearing aid device 120 to confirm that the hearing aid device 120 is not in a wearing state, and the sofa 110 switches to the hearing aid playback mode in response to the first confirmation signal. In the hearing aid playback mode, the sofa 110 receives the first audio data sent by the hearing aid device 120, and the sofa 110 plays the first audio data through the audio output module 112. By playing the first audio data sent by the hearing aid device through the sofa, the user can hear the sound of the hearing aid device without wearing the hearing aid device, which can effectively alleviate the ear health risks that the user may face due to wearing the hearing aid device for a long time, and also improve the intelligence of the sofa and the use experience of the sofa by a specific user group.

[0061] like Figure 2 As shown, in one embodiment, a method for audio output of a sofa is provided, which can be applied to a sofa, wherein the sofa includes an audio output module, and the method may include the following steps:

[0062] Step 202: When the sofa establishes a communication connection with the hearing aid device, a first confirmation signal sent by the hearing aid device is received.

[0063] The first confirmation signal may be sent by the hearing aid device when it is detected that the hearing aid device is not in a wearing state. The "not in a wearing state" refers to a state where the hearing aid device is not in contact with the user's ear. The first confirmation signal may be used to indicate that the hearing aid device is not in a wearing state.

[0064] Optionally, the first confirmation signal may carry a first identifier, which can be used to indicate that the hearing aid device is not in a worn state. When the sofa receives the first confirmation signal sent by the hearing aid device, it can determine that the hearing aid device is not in a worn state based on the first identifier carried by the first confirmation signal.

[0065] In some embodiments, the hearing aid device may be provided with a sensor, which can detect whether the hearing aid device is in a wearing state. Optionally, the sensor may include but is not limited to a pressure sensor, an optical sensor, an infrared sensor, etc. By providing a sensor in the hearing aid device, not only can it be accurately detected whether the hearing aid device is in a wearing state, but also the sofa can be switched to a playback mode in time, so as to realize seamless switching and playback of audio data and prevent the user from missing important information.

[0066] For example, take a pressure sensor as an example. The pressure sensor is set in the handle of the hearing aid device. When the hearing aid device is worn, the handle of the hearing aid device presses on the auricle. The pressure sensor in the handle can be subjected to the pressure of the auricle and convert the pressure change into an electrical signal. The hearing aid device obtains the electrical signal and can identify the current state of the hearing aid device as the wearing state. On the contrary, when the pressure sensor in the handle is not subjected to pressure, that is, the hearing aid device does not obtain the electrical signal or the obtained electrical signal is small, the current state of the hearing aid device can be identified as not being in the wearing state.

[0067] Step 204: In response to the first confirmation signal, switch to the hearing aid playback mode.

[0068] The hearing aid playback mode may be a mode in which the audio output module of the sofa plays the audio data from the hearing aid device. Optionally, when the audio output module of the sofa is switched to the hearing aid playback mode, the hearing aid device may stop playing the first audio data or continue playing the first audio data.

[0069] In some embodiments, the audio output module also has a normal play mode. The normal play mode can be the basic working mode of the audio output module of the sofa. In the normal play mode, the sofa stops receiving the first audio data sent by the hearing aid device, the audio output module stops playing the first audio data sent by the hearing aid device, and the audio output module can play the audio data generated by the sofa itself. For example, the audio output module outputs the prompt audio generated by the sofa, the audio output module outputs the music audio generated by the sofa, etc.

[0070] When the sofa receives the first confirmation signal sent by the hearing aid device, it can switch from the normal playback mode to the hearing aid playback mode.

[0071] Step 206: In the hearing aid playback mode, first audio data sent by the hearing aid device is received, and the first audio data is played through the audio output module.

[0072] The first audio data may refer to audio data obtained by the hearing aid device after conversion according to the collected sound. In the hearing aid playback mode, the hearing aid device first sends the first audio data to the sofa, the sofa receives the first audio data, and then the audio output module of the sofa plays the first audio data.

[0073] For example, Figure 3 The following is a timing diagram of an audio output method for a sofa provided in an embodiment of the present application. Figure 3As shown, after the sofa successfully communicates with the hearing aid device, the user takes off the hearing aid device, and the hearing aid device detects that it is not in the wearing state, so the hearing aid device sends a first confirmation signal to the sofa, and the sofa receives and responds to the first confirmation signal to enter the hearing aid playback mode. In the hearing aid playback mode of the sofa, the sofa receives the first audio data that can be sent by the hearing aid device, and the audio output module of the sofa can play the first audio data from the hearing aid device.

[0074] In the embodiment of the present application, after the hearing aid device is communicatively connected to the sofa, the audio data received by the hearing aid device is played by the audio output module of the sofa, so that the user can hear the sound of the hearing aid device without wearing the hearing aid device. This can not only effectively alleviate the user's ear discomfort caused by wearing the hearing aid device for a long time, but also improve the intelligence of the sofa and enhance the user experience of the sofa for specific user groups.

[0075] Figure 4 This is a flow chart of establishing a communication connection between a sofa and a hearing aid device provided in an embodiment of the present application. Figure 4 As shown, in one embodiment, when the sofa establishes a communication connection with the hearing aid device, before receiving the first confirmation signal sent by the hearing aid device, the following steps may be included:

[0076] Step 402: When it is detected that there is a user sitting on the sofa, search for hearing aids in the surrounding area.

[0077] It should be noted that the sofa can detect whether there is a user in the sofa by using sensor devices including but not limited to optical sensors, pressure sensors or infrared sensors.

[0078] For example, let's take an optical sensor to detect whether there is a user on a sofa. The optical sensor is usually installed under the sofa cushion and can emit infrared light or other non-visible light bands to a certain space above the sofa seat. When a user sits on the sofa, the user's body will block part or all of the light path, causing the optical signal received by the receiver corresponding to the optical sensor to be interrupted, thereby triggering a corresponding logical response, indicating that there is a user on the sofa.

[0079] Optionally, whether there is a user in the sofa can be detected by one of the sensor devices such as an optical sensor, a pressure sensor or an infrared sensor, or by a combination of multiple sensors, but it is not limited thereto.

[0080] The sofa can broadcast a detection signal to a certain area around it to search for electronic devices in the area. After receiving the detection signal, the hearing aid in the area can feed back a response signal to the sofa to indicate that the hearing aid is in the certain area of ​​the sofa.

[0081] Furthermore, the hearing aid device may carry identification information of the hearing aid device in the feedback response signal. After receiving the response signal, the sofa may identify the electronic device hearing aid device that feedbacks the response signal according to the identification information contained in the response signal.

[0082] Optionally, the sofa can store identification information of a hearing aid device that has been connected to the sofa. When the hearing aid device that has been connected to the sofa appears again in the detection area of ​​the sofa, the sofa and the hearing aid device can be automatically connected.

[0083] Step 404: Establish a communication connection with the searched hearing aid device.

[0084] When the sofa searches for the hearing aid device, the sofa can establish a communication connection with the hearing aid device.

[0085] Optionally, the sofa may initiate a communication connection request to the hearing aid device, or the hearing aid device may initiate a communication connection request to the sofa, but the present invention is not limited thereto.

[0086] In the embodiment of the present application, by detecting the presence of a user on the sofa, the communication connection between the sofa and the hearing aid device is achieved, which can ensure the instant response of the hearing aid function of the sofa, enhance the convenience of the sofa and the comfort of user operation, and is conducive to improving the intelligence level of the sofa and user experience.

[0087] In some embodiments, after switching to the hearing aid playback mode in response to the first confirmation signal, the method further includes: receiving playback setting parameters sent by the hearing aid device; and setting the audio output module according to the playback setting parameters.

[0088] The playback setting parameters refer to the setting parameters of the hearing aid device when the hearing aid device plays the first audio data, which may include but are not limited to volume parameters, sound effect parameters, and left and right channel balance parameters, etc. Among them, the volume parameter can be used to adjust the volume when playing audio data, the sound effect parameter can be used to adjust the noise reduction level when playing audio data, and the left and right channel balance parameter can be used to adjust the sound balance of the left and right channels when playing audio data.

[0089] It should be noted that due to the differences in hardware specifications, audio processing technology, etc. between the sofa's audio output module and the hearing aid device, all the playback setting parameters of the hearing aid device cannot be directly applied to the sofa's audio output module. It is necessary to adaptively adjust some playback setting parameters to ensure that the audio finally output by the audio output module can be heard clearly by the user and meets the user's auditory preferences.

[0090] Exemplarily, take the case where the playback setting parameters include a volume parameter, and the volume of the audio output module of the hearing aid device and the sofa are the same, and have the same playback effect as an example. Since the distance from the hearing aid device to the user's ear is different from the distance from the audio output module of the sofa to the user's ear, and the sound intensity will decay during the propagation process, the audio output module of the sofa needs to be adaptively adjusted to achieve the same playback effect as the hearing aid device. The volume parameter of the hearing aid device is 50, and the hearing aid device sends the volume parameter to the sofa as a playback setting parameter. After the sofa receives the volume parameter sent by the hearing aid device, according to the distance from the audio output module of the sofa to the user's ear, the volume parameter of the audio output module is adaptively adjusted to 70 to compensate for the attenuation of the sound intensity during the propagation process, and the audio output module plays the first audio data according to the volume parameter of 70.

[0091] In an embodiment of the present application, the playback setting parameters of the hearing aid are automatically synchronized to the audio output module of the sofa, and the playback setting parameters are adaptively adjusted. This can not only ensure that the sound output by the audio output module is more in line with the user's auditory preferences and hearing conditions, but also avoid the user from manually adjusting the audio settings of the sofa, thereby improving the intelligence of the sofa and enhancing the user experience.

[0092] In some embodiments, the sofa further has a memory, and after the sofa receives the first audio data sent by the hearing aid device, the first audio data is stored; when the sofa establishes a communication connection with the first terminal, the sofa sends the stored first audio data to the first terminal.

[0093] The first terminal may be an electronic terminal device such as a mobile phone, a tablet, a computer, or a cloud terminal such as a cloud platform or a smart home center, but is not limited thereto. The communication connection between the sofa and the first terminal may be a communication connection based on WiFi.

[0094] After receiving the first audio data sent by the hearing aid device, the sofa stores the first audio data in the corresponding storage space, and when the sofa is connected to the first terminal for communication, the sofa uploads the stored first audio data to the first terminal. In this way, the user can review the first audio data on the terminal, which improves the relistenability and manageability of the audio data and enhances the user experience.

[0095] In other embodiments, the sofa also has an analysis function. After receiving the first audio data sent by the hearing aid device, the sofa converts the first audio data into audio text; detects whether the audio text contains preset words, and if so, generates reminder voice data; and sends the reminder voice data to the first terminal.

[0096] The preset words may refer to a series of key words related to emergency situations or specific needs preset in the audio text, including but not limited to "help", "out of medicine", "call 120, etc.", etc.

[0097] The reminder voice data may be voice information dynamically generated according to the preset words detected in the audio text, including a sound segment of the first audio data corresponding to the detected preset words.

[0098] Optionally, the reminder voice data may be generated based on the frequency of the detected preset words, and the reminder voice data may also be generated based on the tone, speech speed, etc. of the first audio data corresponding to the detected preset words, but is not limited thereto.

[0099] For example, if the sofa detects the preset word "help" in the audio text of the first audio data, it generates an emergency distress signal and sends it to the first terminal together with the sound clip of "help" corresponding to the first audio data. This can not only improve the functionality of the sofa, but also enhance the user's sense of security when using the sofa, improve the intelligence of the sofa, and improve the user's sofa rest experience.

[0100] In the following embodiments, a posture detection method is provided to achieve switching different audio output units to play the first audio data according to different postures. Figure 5 This is a flow chart of switching the audio output unit according to the posture provided in the embodiment of the present application. Figure 5 As shown, in one embodiment, the step of playing the first audio data through the audio output module may include the following steps:

[0101] Step 501: Detect the user's posture on the sofa through a posture sensor.

[0102] The audio output module in the sofa includes multiple audio output units, and the multiple audio output units are respectively arranged in different sofa areas of the sofa. For example, audio output unit A is arranged on the left armrest of the sofa, audio output unit B is arranged on the right armrest of the sofa, and audio output unit C is arranged on the backrest of the sofa.

[0103] The sofa may also be provided with a posture sensor, which may be used to detect the position and posture of the user on the sofa. The user position may refer to the specific position of the user sitting on the sofa. For example, on a sofa with multiple seats in a row, the posture sensor may detect the position of the user sitting on the sofa. The user posture may refer to the posture of the user on the sofa, which may include but is not limited to sitting, lying, sideways, leaning forward and other postures.

[0104] The posture sensor is used to identify the user's posture on the sofa, thereby locating the position of each of the user's limbs, and further locating the specific position of the user's ears. When the target audio output unit is subsequently selected to play audio data, it can be ensured that the playback direction of the target audio output unit is directly toward the user's ears.

[0105] The posture sensor may include but is not limited to an accelerometer, a gyroscope, etc. Optionally, the posture sensor may also be a plurality of pressure sensors or optical sensors located on a sofa cushion, and the user posture is simply determined by the number of pressure sensors or optical sensors covered by the user's body.

[0106] Step 503: According to the user gesture, determine a target audio output unit corresponding to the user gesture from a plurality of audio output units.

[0107] According to the user's posture, the most suitable audio output unit in the current posture is determined as the target audio output unit from the multiple audio output units in the sofa. Furthermore, in the case where the user's posture changes significantly, the most suitable audio output unit can also be re-determined as the target audio output unit based on the latest user posture. It should be noted that the most suitable audio output unit mentioned above not only refers to the most suitable playback effect obtained by setting the playback setting parameters, but also includes the most suitable listening effect for the user. Among them, the factor affecting the user's listening effect can be the distance from the audio output unit to the user's ear, but is not limited to this.

[0108] Optionally, the target audio output unit may be one or more than one, that is, the first audio data may be played simultaneously through multiple audio output units, but the present invention is not limited thereto.

[0109] For example, the user's postures on the sofa are sitting and lying respectively, and the sofa has an audio output unit A and an audio output unit B. The posture sensor detects that the user is sitting on the sofa, and determines that the audio output unit A located at the back of the sofa is closest to the user's ear and has the best playback and listening effects, so the audio output unit A is set as the target audio output unit; then the posture sensor detects that the user's posture on the sofa changes from sitting to lying, and re-determines that the audio output unit B located at the armrest of the sofa is closest to the user's ear, so the audio output unit B is set as the target audio output unit.

[0110] Step 505: Play the first audio data through the target audio output unit.

[0111] Further, during the process of the user's posture changing on the sofa, once the target audio output unit is updated, the first audio data is played by the most recently determined target audio output unit.

[0112] For example, the user's postures on the sofa are sitting and lying respectively, and the sofa has an audio output unit A and an audio output unit B. After the user sits on the sofa, the posture sensor detects that the user's posture is sitting, so the audio output unit A located at the back of the sofa is used as the target audio output unit, and the first audio data received by the sofa is played by the audio output unit A. Subsequently, the user lies on the sofa, and the posture sensor detects that the user's posture changes from sitting to lying, so the audio output unit B located at the armrest of the sofa is re-determined as the target audio output unit, and the audio output unit B plays the first audio data received by the sofa.

[0113] In an embodiment of the present application, the sofa can select the most suitable audio output unit to play the first audio data according to the user's posture, which can not only reduce the attenuation and interference of the audio data, improve the sound quality and clarity, so that the user can hear the audio content of the hearing aid device more clearly, but also improve the intelligence level of the sofa and improve the user's comfort.

[0114] In the following embodiments, a method for performing noise reduction processing on first audio data is provided to obtain second audio data of higher quality and improve the user's hearing aid experience. Figure 6 This is a flowchart of performing noise reduction processing on first audio data provided by an embodiment of the present application. Figure 6 As shown, in one embodiment, the step of playing the second audio data through the audio output module may include the following steps:

[0115] Step 602: In the hearing aid playback mode, first audio data sent by the hearing aid device is received.

[0116] During the operation of hearing aids, many types of noise are generated, including but not limited to transient noise, steady-state noise or feedback noise. Transient noise can refer to non-continuous pulse noise, including but not limited to door slamming, collision, breaking, etc. Steady-state noise can refer to regular and stable background noise, such as the noise from refrigerators and air conditioners, or wind noise, that is, the noise caused by the pressure change caused by the rapid flow of air around the sound inlet of the microphone of the hearing aid; feedback noise can refer to the howling caused by the repeated amplification of the same audio data by the hearing aid, or it can refer to the internal noise of the hearing aid, that is, the noise caused by the failure or damage of the hearing aid itself.

[0117] Step 604: identify the first audio data to determine the noise category corresponding to the first audio data.

[0118] The noise category of the first audio data may include transient noise, steady-state noise or feedback noise. The sofa may identify the noise category of the first audio data through an algorithm, or the sofa may actively emit a sound, and identify the noise category by comparing the first audio data with the audio data converted after the hearing aid device collects the sound, but is not limited thereto.

[0119] Exemplarily, for transient noise and howling-type feedback noise, Sofa can use a machine learning algorithm or a deep learning algorithm to identify whether transient features such as sudden peaks and sharp changes in spectrum appear in the first audio data, thereby determining whether the first audio data contains transient noise; for steady-state noise, Sofa can identify whether it contains steady-state noise by analyzing the time series characteristics of the first audio data; for machine failure-type feedback noise, it can identify whether this type of feedback noise exists by checking the components of the hearing aid device.

[0120] Step 606: Perform noise reduction processing on the first audio data according to an algorithm corresponding to the noise category of the first audio data to obtain second audio data.

[0121] It should be noted that in the process of collecting sound data and generating the first audio data by the hearing aid device, the hearing aid device has already performed the first noise reduction process. However, in order for the sofa to achieve a suitable hearing aid effect, the amplification factor of the sofa audio output module is usually much larger than that of the hearing aid device, which makes the extremely small noise in the hearing aid device become very obvious after being amplified by the audio output module. Therefore, it is necessary to perform a second noise reduction process on the first audio data before the audio output module plays it.

[0122] For transient noise, since its characteristic is that the sound intensity rises rapidly in a short period of time and the maximum intensity is much higher than the long-term average value of other sounds, transient noise can be suppressed by reducing the gain of the corresponding frequency band; for steady-state noise and feedback noise, the interference of steady-state noise can be reduced by attenuating the gain of the low-frequency area where the steady-state noise is concentrated or changing the directionality of the microphone, but it is not limited to this.

[0123] For example, taking wind noise as an example, since wind noise is generally concentrated in low frequencies, wind noise suppression can be achieved by attenuating the gain in the low-frequency region, or by dynamically adjusting the gain and attenuation according to the characteristics of the first audio data by designing an adaptive filter algorithm, thereby minimizing the impact of wind noise, or by introducing dual microphones and using the autocorrelation of dual microphone input signals to detect wind noise, or by using a deep learning algorithm to separate wind noise from the first audio data by training a model.

[0124] Step 608: Play the second audio data through the audio output module.

[0125] Optionally, an algorithm module may be built into the sofa, and the algorithm module is used to perform noise reduction processing on the received first audio data to obtain second audio data.

[0126] Optionally, after the audio data module of the sofa performs noise reduction processing on the first audio data to obtain the second audio data, the sofa may further store the second audio data.

[0127] Optionally, the audio output module includes multiple audio output units, and the target audio output unit is the audio output unit corresponding to the current user posture; the first audio data is subjected to noise reduction processing by the deep learning algorithm built into the audio output module to obtain the second audio data, and the second audio data is played by the target audio output unit.

[0128] For example, the first audio data sent by the hearing aid device contains background noise and wind noise, and the algorithm module contains a deep learning algorithm. In the hearing aid playback mode, the sofa receives the first audio data sent by the hearing aid device, and identifies the noise type of the first audio data as background noise and wind noise according to the algorithm module built into the sofa. Subsequently, the deep learning algorithm is used to separate the background noise and wind noise in the first audio data through the training model to obtain the second audio data that does not contain background noise and wind noise, and the second audio data is then played by the audio output module.

[0129] In an embodiment of the present application, the audio output module of the sofa performs noise reduction processing on the first audio data, obtains and plays the second audio data, can provide a more personalized hearing aid function, enhance the practicality and adaptability of the sofa, and can also provide better quality audio data to help users hear the sound better, improve the intelligence level of the sofa, and enhance the user's sofa experience.

[0130] Figure 7 This is a flow chart of another audio output method for a sofa provided in an embodiment of the present application. Figure 7 As shown, in one embodiment, the method may include the following steps:

[0131] Step 701: When the sofa establishes a communication connection with the hearing aid device, a first confirmation signal sent by the hearing aid device is received.

[0132] The first confirmation signal is sent by the hearing aid device when it detects that the hearing aid device is not in the wearing state.

[0133] Step 703: In response to the first confirmation signal, switch to the hearing aid playback mode.

[0134] Step 705: In the hearing aid playback mode, first audio data sent by the hearing aid device is received, and the first audio data is played through the audio output module.

[0135] Step 707: Receive a second confirmation signal sent by the hearing aid device.

[0136] The second confirmation signal is sent by the hearing aid device when it detects that the hearing aid device is in a wearing state. It should be noted that the audio output module should stop playing the first audio data sent by the hearing aid device after the user has put on the hearing aid device to ensure the continuity of the audio data playback and prevent the main audio data from being missed.

[0137] Step 709: In response to the second confirmation signal, switch to the normal play mode.

[0138] The normal play mode is the basic working mode of the audio output module of the sofa. In this mode, the sofa stops receiving the first audio data sent by the hearing aid device, and the audio output module stops playing the first audio data sent by the hearing aid device.

[0139] Step 711: In the normal playback mode, stop receiving the first audio data sent by the hearing aid device.

[0140] In the normal playing mode, the sofa stops receiving the first audio data sent by the hearing aid device, the audio output module stops playing the first audio data sent by the hearing aid device, and the hearing aid device plays the first audio data.

[0141] Optionally, after the sofa switches to normal playback mode, the sofa may actively disconnect the communication connection with the hearing aid device, or it may not actively disconnect the communication connection with the hearing aid device, but automatically disconnect the communication connection with the hearing aid device when the hearing aid device moves out of the detection range of the sofa, but is not limited to this.

[0142] Figure 8 This is a timing diagram of ending the sofa hearing aid playback mode provided in an embodiment of the present application. Figure 8 As shown, when the sofa establishes a communication connection with the hearing aid device, when the user takes off the hearing aid device, the hearing aid device triggers a first confirmation signal, and the sofa receives and responds to the first confirmation signal sent by the hearing aid device, switching from the normal playback mode to the hearing aid playback mode. In the hearing aid playback mode, the sofa receives the first audio data sent by the hearing aid device, and plays the first audio data through the audio output module. When the user is wearing the hearing aid device, the hearing aid device triggers a second confirmation signal to confirm that the user has worn the hearing aid device. The sofa receives and responds to the second confirmation signal, the audio output module switches from the hearing aid playback mode to the normal playback mode, the audio output module stops playing the first audio data sent by the hearing aid device, and the hearing aid device plays the first audio data.

[0143] In the embodiment of the present application, by automatically exiting the hearing-aid playback mode of the sofa, seamless playback of the first audio data between the sofa and the hearing-aid device is achieved, which is not only conducive to ensuring the continuity of the audio data playback and preventing the omission of important audio data, but also the user does not need to manually adjust the settings of the sofa or the hearing-aid device, but only needs to wear the hearing-aid device to complete the connection, which greatly improves the convenience and comfort of the user in using the sofa. In addition, it can further improve the automation and intelligence level of the sofa.

[0144] In a specific embodiment, the audio output module of the sofa includes two audio output units, wherein audio output unit A is suitable for the audio output of the sofa when the user is in a sitting position, and audio output unit B is suitable for the audio output of the sofa when the user is in a lying position, and the hearing aid device converts the collected sound into the first audio data. When it is detected that there is a user in the sofa, the sofa searches for the hearing aid devices in the surrounding area, initiates a communication connection request to the searched hearing aid devices, and completes the communication connection with the searched hearing aid devices. Subsequently, when the user takes the hearing aid device off the ear, the hearing aid device detects that it is not in the wearing state, and the hearing aid device sends a first confirmation signal to the sofa, and the sofa receives and responds to the first confirmation signal and switches to the hearing aid playback mode.

[0145] In the hearing-aid playback mode, the sofa receives the playback setting parameters sent by the hearing-aid device, completes the adaptive setting of the playback setting parameters of each audio output unit in the audio output module, receives the first audio data sent by the hearing-aid device, performs noise reduction processing on the first audio data through the built-in algorithm module, identifies and separates the noise of the first audio data, and obtains the second audio data. The sofa recognizes that the user's posture is sitting through the posture sensor, and confirms the audio output unit A as the target audio output unit. When the target audio output unit is confirmed, the second audio data after noise reduction is played through the audio output unit A. During the playback process, the sofa recognizes that the user's posture changes from sitting to lying through the posture sensor, so the audio output unit B is confirmed as the target audio output unit, and the second audio data after noise reduction is played through the audio output unit B.

[0146] After the user has rested enough on the sofa, he puts on the hearing aid device and prepares to leave the sofa. During this process, the hearing aid device detects that the user is wearing the hearing aid device, so the hearing aid device sends a second confirmation signal to the sofa. The sofa receives and responds to the second confirmation signal and switches to the normal playback mode. In the normal playback mode, the sofa stops receiving the first audio data sent by the hearing aid device, the target audio output unit stops playing the second audio data after noise reduction, and the hearing aid device plays the first audio data.

[0147] The audio output method of the sofa described in the above embodiment can not only enable the user to take off the hearing aid device when resting on the sofa, reducing the negative impact of wearing the hearing aid device for a long time on the ears, but also ensure that the audio data can have the best playback effect under different user postures through automatic noise reduction and intelligent audio output unit switching; at the same time, the sofa playback mode is switched according to the intelligent wearing detection function of the hearing aid device, which can not only reduce the user's manual operation, but also realize the seamless connection between the hearing aid device and the sofa in audio data playback, thereby improving the intelligence level of the sofa and bringing users a more comfortable and intelligent sofa rest experience.

[0148] In other embodiments, before receiving the first confirmation signal sent by the hearing aid device, the method also includes: sending first guidance voice data to the hearing aid device, the first guidance voice data being used to guide the user of the hearing aid device to take off the hearing aid device; the method also includes: playing second guidance voice data through the audio output module, or sending second guidance voice data to the hearing aid device, the second guidance voice data being used to guide the user to place the hearing aid device in the accommodation area on the sofa.

[0149] The first guiding voice data is used to guide the user wearing the hearing aid device to take off the hearing aid device, and the second guiding voice data is used to instruct the user to place the hearing aid device in the accommodation area on the sofa. It should be noted that after the sofa and the hearing aid device complete the communication connection, the user is sitting on the sofa and the hearing aid device is in the wearing state, so the first guiding voice data is sent by the sofa and played by the hearing aid device to guide the user to take off the hearing aid device. After the user takes off the hearing aid device, the hearing aid device is not in the wearing state, and the user cannot hear the audio data sent by the hearing aid device, but can hear the audio data played by the audio output module of the sofa. Therefore, the second guiding voice data is played by the audio output module of the sofa to guide the user to place the hearing aid device in the designated accommodation area of ​​the sofa. The accommodation area refers to an area or space on the sofa specially designed or designated for placing hearing aid devices.

[0150] Further, after the user places the hearing aid device in the designated accommodation area, the audio output module of the sofa stops playing the second guiding voice data.

[0151] It should be noted that since the sofa has entered the hearing-aid playback mode during the process of playing the second guidance voice data, the audio output module of the sofa can also play the first audio data. Therefore, when the audio output module of the sofa has multiple audio output units, one audio output unit can play the first audio data and another audio output unit can play the second guidance voice data, or the second guidance voice data can be played in the interval when the audio output module is not playing the first audio data, but it is not limited to this.

[0152] Optionally, a light strip is provided in the accommodation area of ​​the sofa, and while the audio output module of the sofa plays the second guiding voice data, the light strip in the accommodation area of ​​the sofa will light up to guide the user to place the hearing aid device in the designated accommodation area. After the user places the hearing aid device in the designated accommodation area, the light strip in the accommodation area of ​​the sofa stops emitting light.

[0153] Optionally, the accommodation area of ​​the sofa is a charging area, which is provided with a charging interface suitable for the hearing aid device. When the user places the hearing aid device in the area, the hearing aid device can be charged.

[0154] Optionally, the accommodating area of ​​the sofa may be located at the armrests of the sofa, or at the corners of the sofa, but is not limited thereto.

[0155] For example, the accommodation area of ​​a sofa is located at the armrest of the sofa, and there is a light strip around the area. After the sofa completes the communication connection with the hearing aid device, the sofa sends the first guiding voice data to the hearing aid device, and the hearing aid device plays the first guiding voice data to guide the user to take off the hearing aid device. After the user takes off the hearing aid device, the audio output module of the sofa plays the second guiding voice data, and controls the light strip of the accommodation area to illuminate, guiding the user to place the taken-off hearing aid device on the accommodation area. After the user places the hearing aid device in the accommodation area, the audio output module of the sofa stops playing the second guiding voice data, and the light strip of the accommodation area stops emitting light.

[0156] In an embodiment of the present application, by playing guiding voice data to the user, guiding the user to take off the hearing aid device and place the hearing aid device in a designated area, not only can the risk of damage or loss of the hearing aid device due to random placement be reduced, the safety and reliability of the use of the sofa and the hearing aid device be increased, but also the functionality of the sofa can be improved and the user experience can be enhanced.
