[0110] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0111] Generally, audio devices of different product types or models have different hardware acoustic forms. For example, differences in the number of microphones, array orientation, cavity design, device selection, etc. will result in different sound pickup capabilities and sound quality of the audio devices. Among them, the quality of the sound pickup capability directly affects the user experience of the audio device such as voice calls and wake-up recognition; the quality of the sound directly affects the user experience of playing music.

[0112] During the design phase of audio equipment, acoustic engineers will perform software adjustments to acoustic parameters based on the hardware acoustic form of the audio equipment. For example, by adjusting the gain parameters of the microphone input signal, when the audio equipment is in a noisy environment or the sound source is far away from the microphone, it can still receive a clearer recording signal, thereby improving the sound pickup capability of the audio equipment. For another example, by adjusting the sound effect parameters of the audio output signal, such as the equalizer (EQ) for gain adjustment of different frequency bands of audio signals, the dynamic range control (DRC) parameters for soft processing and amplitude limitation of audio signals, etc., the sound finally output by the speaker is more realistic and pleasant, thereby improving the sound quality of the audio equipment.

[0113] In the related art, the acoustic parameters adjusted by the software are usually fixed in the software package in the form of hard coding or configuration files. The hard coding form refers to directly embedding the acoustic parameters into the software program, and the configuration file form refers to saving the acoustic parameters in a fixed file format in the memory of the audio device. When the acoustic parameters of the audio device are set or the acoustic parameters of the audio device need to be modified and optimized, the entire software package needs to be downloaded, the acoustic parameters are parsed to obtain the acoustic parameters, and then the acoustic parameters are set.

[0114] Figure 1 The figure shows an example of acoustic parameter settings of different audio devices in the related art. Figure 1 In the example, different types of audio equipment A, B, C, ..., N have different acoustic parameters due to different acoustic morphologies. Figure 1 It can be seen that the process of audio device A continuously optimizing and setting acoustic parameters is as follows: by downloading software package A.1.0, acoustic parameters a.1.0 are set; by downloading software package A.2.0, acoustic parameters a.2.0 are set; by downloading software package A.3.0, acoustic parameters a.3.0 are set; by downloading software package AN0, acoustic parameters an0 are set. The process of audio devices B, C, ..., N continuously optimizing and setting acoustic parameters can be understood by referring to the process of audio device A continuously optimizing and setting acoustic parameters, which will not be repeated here.

[0115] It is understandable that in the related art, in order to set matching acoustic parameters for audio devices of different acoustic forms, it is necessary to develop and maintain a set of software packages with solidified acoustic parameters for each of the N different types of audio devices, such as Figure 1 In addition, in order to improve the sound pickup capability and sound quality of the audio device, the acoustic parameters may be modified and optimized. Once the acoustic parameters of a certain model of audio device need to be modified and optimized, the software package of the audio device of that model needs to be updated separately, for example Figure 1 If the audio device A in the audio system needs to modify and optimize the acoustic parameters to a.2.0, a.3.0, ..., an0, then its software package needs to be updated to A.2.0, A.3.0, ..., AN0, and the same is true for other types of audio devices. Therefore, the relevant technology requires the development and maintenance of different software packages for different audio devices, which has high development complexity, low efficiency, and high maintenance costs. In addition, since the downloaded software package is usually large in bytes and takes a long time to download, users will notice it, resulting in a poor user experience.

[0116] In this regard, the embodiment of the present disclosure provides a parameter setting method, the execution subject of which can be an audio device or a server, wherein the audio device can be a smart speaker; it can also be a household appliance such as a refrigerator and a washing machine equipped with an intelligent voice module, or a mobile phone, a camera, a tablet computer, a vehicle-mounted device, a wearable device, etc. In some possible implementations, the parameter setting method can be implemented by a processor calling a computer-readable instruction stored in a memory.

[0117] Figure 2 This is an example of a parameter setting method flow shown in the embodiment of the present disclosure. Figure 1 , used in audio equipment, by Figure 2 It can be seen that the following steps are included:

[0118] S101, in response to the audio device being connected to the network, sending an acoustic parameter download request to a server;

[0119] S102, receiving the acoustic parameters fed back by the server according to the acoustic parameter download request;

[0120] S103: Using a preset software package in the audio device to set the acoustic parameter to an audio application in the audio device.

[0121] In step S101, when the audio device is connected to the network, an acoustic parameter download request is sent to the server; wherein, the audio device is connected to the network, which can be achieved by the audio device itself, after searching the network, based on a preset network password; or, based on other terminal devices (such as mobile phones, tablet computers) that communicate with the audio device, after the terminal device scans the audio device to be connected to the network, the network name and password are sent to the audio device through a communication method such as Wi-Fi or Bluetooth through the network name and password input by the user, so that the audio device is connected to the network based on the network name and password. After the audio device of the embodiment of the present disclosure is connected to the network, it has the ability to communicate with the server.

[0122] Figure 3 This is a diagram showing an example of communication between an audio device and a server according to an embodiment of the present disclosure. Figure 3 In the example, after the audio devices A, B, C, ..., N identified by L1 are connected to the network, they can communicate with the server identified by L3 through the wireless communication node (such as a router) identified by L2.

[0123] In response to the audio device being connected to the Internet, the embodiment of the present disclosure sends a request for downloading acoustic parameters to the server in a timely manner; or when the audio device is connected to the Internet, sends a request for downloading acoustic parameters to the server based on a preset timing, etc., which is not limited in the embodiment of the present disclosure. The preset timing can be a user-defined time, or a time when the audio device is less frequently used, such as at night.

[0124] After the audio device sends an acoustic parameter download request to the server, the server feeds back the acoustic parameters to the audio device, so that in step S102, the audio device receives the acoustic parameters fed back by the server according to the acoustic parameter download request. The acoustic parameters of the disclosed embodiment include at least one of the following: a gain parameter of an audio input signal, an EQ equalizer algorithm parameter of an audio output signal, and a DRC dynamic range control parameter; wherein the EQ equalizer is an algorithm that can adjust the amplification amount of electrical signals of various frequency components respectively, and compensates for the defects of the speaker and the sound field by adjusting electrical signals of various frequencies, and compensates and modifies various sound sources, that is, in order to truly restore the sound, the frequency response curve of the audio device is adjusted to be flatter by adjusting the parameters of the EQ equalizer, and the EQ equalizer algorithm parameters include the type of filter and the parameters of various filters, such as frequency, gain, quality factor, etc.; DRC dynamic range control is an algorithm that dynamically controls the amplitude of the audio output signal, provides compression and amplification capabilities for the output audio, can make small-amplitude sounds louder, or large-amplitude sounds more whispering and soft, and filters out some low-level noise, and is a nonlinear amplitude adjustment method for audio signals, and the DRC dynamic range control parameters include but are not limited to enhancement threshold, restriction threshold, noise threshold, etc.

[0125] In addition, the acoustic parameters of the embodiments of the present disclosure may be associated with a version number, an identifier of an audio device, etc., wherein the identifier of the audio device may include a model number, a serial number, etc. of the audio device. The audio device may be uniquely identified by the identifier of the audio device, and the acoustic parameters of different versions of the audio device may be distinguished by the version number.

[0126] In step S103, the audio device uses a preset software package to set the acoustic parameters fed back by the server to the audio application in the audio device; wherein the preset software package can be a software package image burned into the memory of the audio device when the audio device is produced in the factory, or sent out once by the server. The audio applications in the audio device include music playback applications, video applications, voice control applications, etc.

[0127] It should be noted that different audio devices in the embodiments of the present disclosure may store the same software package, so that the same manufacturer can set different acoustic parameters based on the same software package, greatly reducing development and maintenance costs.

[0128] The preset software package of the disclosed embodiment includes at least software code (such as a preset loading module) for setting acoustic parameters to audio applications. Through the loading module in the preset software package, the acoustic parameters fed back by the server are set to the audio applications in the audio device. For example, the gain parameters of the audio input signal are loaded into the voice control application, and the EQ equalizer algorithm parameters and DRC dynamic range control parameters of the audio output signal are loaded into the music playback application, the video application, etc., so that the audio device runs each audio application based on the acoustic parameters.

[0129] In addition, the preset software package of the disclosed embodiment may also include module codes such as a business general module, a request module, an acquisition module, a storage module, a parsing module, an audio input processing module, and an audio output processing module. Among them, the business general module refers to a business module common to audio devices, which serves the basic product requirements of audio devices, including but not limited to networking, button control, display component control, voice interaction control, voice call control, resource playback, home control, and software processes such as Over-the-Air Technology (OTA). The request module is used to send an acoustic parameter download request to the server after the audio device is turned on and connected to the network. The acquisition module is used for the audio device to receive the acoustic parameters fed back by the server according to the acoustic parameter download request. The storage module is used for the audio device to directly store the acoustic parameters in a preset memory space or store them in the form of files after receiving the acoustic parameters fed back by the server. The parsing module is used to parse the acoustic parameters stored in the form of files, so that the loading module sets the parsed acoustic parameters to the software processing module corresponding to the audio application for operation. The audio input processing module is used to process parameters such as the gain of the audio input signal after setting, so that the audio application runs based on the gain of the audio input signal and other parameters; in addition, the audio input module can also process and adjust the audio input signal recorded by the microphone, such as echo cancellation processing, noise reduction processing, etc., so that the device can finally obtain a processed and clearer audio signal to improve the sound pickup ability of the audio device. The audio output processing module is used to process the EQ equalizer algorithm parameters after setting, so that the audio application runs based on the EQ equalizer algorithm parameters; in addition, the audio output module can also process and adjust the audio output signal, such as volume control processing, DRC dynamic range control processing, etc., so that the sound finally output by the device's speaker is more realistic and pleasant to the ear, so as to improve the sound quality of the device.

[0130] It can be understood that in the scenario of setting the acoustic parameters of an audio device, compared with the method of solidifying the acoustic parameters into a software package, which requires downloading and updating the entire software package, the embodiment of the present disclosure decouples the acoustic parameters from the software package, receives the acoustic parameters fed back by the server according to the acoustic parameter download request after the audio device is connected to the network, and uses the preset software package in the audio device to set the acoustic parameters to the audio application in the audio device. On the one hand, by only requesting to download the acoustic parameters, the acoustic parameters can be set using the software package, thereby reducing development and maintenance costs. On the other hand, the embodiment of the present disclosure can also enable the audio device to update the acoustic parameters in the scenario of optimizing the acoustic parameters by only receiving the acoustic parameters fed back by the server (without updating the software package), thereby improving the parameter setting efficiency. At the same time, since the number of bytes of the acoustic parameters is smaller than that of the entire software package, downloading and setting the acoustic parameters is more imperceptible, thereby improving the user experience by optimizing the acoustic parameters in a silent update that is more imperceptible to the user.

[0131] In some embodiments, in response to the audio device being connected to the network, sending an acoustic parameter download request to the server includes:

[0132] In response to the audio device being connected to the network, determining whether the audio device stores acoustic parameters;

[0133] When it is determined that the audio device does not store the acoustic parameters, sending a request to download the acoustic parameters to the server;

[0134] or,

[0135] In the case where it is determined that the audio device stores the acoustic parameters, in response to receiving the acoustic parameter update notification sent by the server, the acoustic parameter download request is sent to the server.

[0136] In the disclosed embodiment, when the audio device is connected to the Internet, it is determined whether the audio device has stored acoustic parameters. If the audio device does not have stored acoustic parameters, such as the audio device is turned on and connected to the Internet for the first time, or the audio device is reset, resulting in no acoustic parameters stored in the audio device, the audio device promptly sends an acoustic parameter download request to the server, receives the acoustic parameters fed back by the server, and uses a preset software package to set the acoustic parameters to the audio application in the audio device. Through this solution, the audio device can operate normally while improving the immediacy of the acoustic parameter setting of the audio device.

[0137] If the audio device stores acoustic parameters, in response to receiving an acoustic parameter update notification sent by the server, an acoustic parameter download request is sent to the server, the updated acoustic parameters fed back by the server are received, and the updated acoustic parameters are set to the audio application in the audio device using a preset software package. The server sends an acoustic parameter update notification to the audio device, which may be in response to an acoustic parameter update in the server, and the server sends an acoustic parameter update notification to the audio device; or when it is determined that the acoustic parameters currently stored in the audio device are inconsistent with the acoustic parameters maintained in the server, an acoustic parameter update notification is sent to the audio device, etc. Since the updated acoustic parameters are usually based on parameters that are more closely matched to the acoustic morphology of the audio device after adjustment by an acoustic engineer, the audio device can provide users with a better acoustic experience based on the updated acoustic parameters in a timely manner.

[0138] It should be noted that if the audio device is currently in a powered-off and offline state, the above acoustic parameter setting process will be performed after the audio device is powered on and connected to the network next time, which will not be described in detail here.

[0139] In some embodiments, the method further comprises:

[0140] According to the acoustic parameter update notification, updating the acoustic parameters stored in the audio device to the acoustic parameters fed back by the server according to the acoustic parameter download request;

[0141] The step of setting the acoustic parameters to an audio application in the audio device by using a preset software package in the audio device comprises:

[0142] The updated acoustic parameters are set to the audio application in the audio device using the preset software package.

[0143] In the embodiment of the present disclosure, after receiving the acoustic parameter update notification sent by the server, the audio device updates the stored acoustic parameters to the acoustic parameters fed back by the server, so that the acoustic parameters stored in the audio device are consistent with the updated acoustic parameters in the server, and the updated acoustic parameters are set to the audio application in the audio device using the preset software package. Compared with the audio device downloading the updated acoustic parameters in the server every time it is turned on and run, the audio device in the embodiment of the present disclosure stores the updated acoustic parameters after requesting the acoustic parameter download once, so that the acoustic parameters stored in the audio device are consistent with the updated acoustic parameters in the server, which can reduce the number of times the acoustic parameter download request is sent to the server and reduce network communication overhead.

[0144] In some embodiments, the acoustic parameter download request carries an identifier of the audio device; and receiving the acoustic parameter fed back by the server according to the acoustic parameter download request includes:

[0145] The acoustic parameter corresponding to the identifier of the audio device fed back by the server according to the acoustic parameter download request is received.

[0146] In the embodiment of the present disclosure, the acoustic parameter download request carries the identifier of the audio device; wherein the identifier of the audio device, such as the model and serial number of the audio device, can uniquely identify the information of the audio device.

[0147] In the embodiment of the present disclosure, the audio device sends an acoustic parameter download request carrying the identification of the audio device to the server; the server searches for the acoustic parameters corresponding to the identification based on the received acoustic parameter download request, and feeds back the acoustic parameters corresponding to the identification to the audio device, so that the audio device receives the acoustic parameters corresponding to the identification of the audio device fed back by the server based on the acoustic parameter download request.

[0148] It can be understood that, when the server maintains the acoustic parameters of multiple audio devices, the audio device sends an acoustic parameter download request carrying the identification of the audio device to the server, so that the server can accurately feedback the acoustic parameters corresponding to the identification to the audio device, that is, the feedback acoustic parameters are acoustic parameters that match the acoustic morphology of the audio device, thereby improving the acoustic experience brought by the audio device running the audio application with the feedback acoustic parameters.

[0149] In some embodiments, the method further comprises:

[0150] encrypting the identification of the audio device;

[0151] In response to the audio device being connected to the network, sending an acoustic parameter download request to the server comprises:

[0152] In response to the audio device being connected to the network, sending an acoustic parameter download request carrying the encrypted identifier to the server;

[0153] The receiving the acoustic parameter corresponding to the identifier of the audio device fed back by the server according to the acoustic parameter download request includes:

[0154] Receive the acoustic parameter corresponding to the decrypted identifier fed back by the server; wherein the decrypted identifier is obtained by the server decrypting the encrypted identifier carried in the acoustic parameter download request.

[0155] In the embodiment of the present disclosure, the audio device encrypts the identification of the audio device using a symmetric encryption algorithm, an asymmetric encryption algorithm, a hash algorithm, etc.

[0156] In response to the audio device being connected to the Internet, the disclosed embodiment sends an acoustic parameter download request carrying an encrypted identifier to a server; after receiving the acoustic parameter download request, the server decrypts the identifier and feeds back the acoustic parameters corresponding to the decrypted identifier to the audio device, so that the audio device receives the acoustic parameters corresponding to the decrypted identifier fed back by the server.

[0157] It can be understood that the audio device in the embodiment of the present disclosure sends an acoustic parameter download request carrying the encrypted audio device identifier to the server, which can improve the confidentiality of the acoustic parameter download request from the audio device to the server and provide a high level of communication security.

[0158] In some embodiments, the feedback acoustic parameter includes an encrypted acoustic parameter; and using a preset software package in the audio device to set the acoustic parameter to an audio application in the audio device includes:

[0159] Decrypting the encrypted acoustic parameters of the feedback;

[0160] In case the decryption is successful, the decrypted acoustic parameters are set to the audio application in the audio device using the preset software package.

[0161] In the embodiment of the present disclosure, after receiving the acoustic parameter download request, the server encrypts the acoustic parameters to be fed back, and feeds back the encrypted acoustic parameters to the audio device.

[0162] The audio device of the disclosed embodiment decrypts the encrypted acoustic parameters fed back by the server. For example, based on the same agreed key, after the server encrypts the acoustic parameters using the key, the audio device decrypts the acoustic parameters based on the key. For another example, if the encrypted acoustic parameters are obtained by the server encrypting the acoustic parameters using a parameter public key, the audio device decrypts the acoustic parameters based on a parameter private key corresponding to the parameter public key.

[0163] When the encrypted acoustic parameters are successfully decrypted, the audio device uses the preset software package to set the decrypted acoustic parameters to the audio application in the audio device. Through this solution, the confidentiality of the acoustic parameters in the audio device download server can be improved, and the communication security is relatively high.

[0165] In response to the audio device being connected to the network, sending a verification request carrying an identification of the audio device to the server;

[0166] Receiving a verification result fed back by the server according to the verification request;

[0167] In response to the verification result indicating that the verification is passed, the acoustic parameter download request is sent to the server.

[0168] In an embodiment of the present disclosure, in response to the audio device being connected to the Internet, a verification request carrying an identification of the audio device is sent to a server; after receiving the verification request, the server feeds back a verification result to the audio device based on the identification of the audio device; for example, if the identification of the audio device is consistent with the identification recorded in the server, a result indicating that the verification passed is fed back to the audio device; if the identification of the audio device is inconsistent with the identification recorded in the server, a result indicating that the verification failed is fed back to the audio device.

[0169] When the audio device receives the characterization verification feedback from the server and it passes, it sends an acoustic parameter download request to the server, so as to set the acoustic parameters fed back by the server according to the acoustic parameter download request to the audio application using the preset software package.

[0170] It can be understood that in the embodiment of the present disclosure, when the audio device receives a verification result indicating that the verification has passed, it requests the server to download the acoustic parameters, so that the audio device that has passed the verification can download the acoustic parameters from the server, which can reduce the information leakage and network communication overhead caused by the audio device that has not passed the verification downloading the acoustic parameters.

[0171] In some embodiments, the acoustic parameters include audio input parameters and / or audio output parameters; and using a preset software package in the audio device to set the acoustic parameters to an audio application in the audio device includes:

[0172] Using the preset software package to set the audio input parameters to an audio receiving application in the audio device;

[0173] and / or,

[0174] The audio output parameters are set to an audio output application in the audio device using the preset software package.

[0175] In the embodiments of the present disclosure, the acoustic parameters include audio input parameters and / or audio output parameters; wherein the audio input parameters include the gain of the audio input signal, the parameters of the echo cancellation processing algorithm, the parameters of the noise reduction processing algorithm, etc.; the audio output parameters include EQ equalizer algorithm parameters, volume parameters, DRC dynamic range parameters, etc.

[0176] The audio device of the embodiment of the present disclosure uses a preset software package to set the audio input parameters to the audio receiving application in the audio device; wherein the audio receiving application corresponds to the aforementioned voice control application. For example, the preset software package is used to set the gain of the audio input signal to the voice control application in the smart speaker, so that the voice control application receives sound with the gain of the audio input signal, thereby improving the sound pickup capability of the voice control application.

[0177] The audio device of the embodiment of the present disclosure uses a preset software package to set audio output parameters to an audio output application in the audio device; wherein the audio output application corresponds to the aforementioned music application, video application, etc. For example, the preset software package is used to set the EQ equalizer algorithm parameters to the music playback application, so that the music playback application plays music with the EQ equalizer algorithm parameters, thereby improving the output sound quality of the music playback application.

[0178] It can be understood that the audio device of the embodiment of the present disclosure uses a preset software package to set audio input parameters to an audio receiving application in the audio device, and / or uses a preset software package to set audio output parameters to an audio output application in the audio device, so that after requesting the server to download the audio input parameters and / or audio output parameters, the preset software package is used to set the parameters to the application accordingly, thereby improving the sound pickup capability and / or sound quality of the audio device.

[0179] Figure 4 This is an example of a parameter setting method flow shown in the embodiment of the present disclosure. Figure 2 , used in the server, by Figure 4 It can be seen that the following steps are included:

[0180] S301, receiving an acoustic parameter download request sent by an audio device;

[0181] S302: Feedback acoustic parameters to the audio device according to the acoustic parameter download request; wherein the acoustic parameters are used by the audio device to set the acoustic parameters to an audio application in the audio device using a preset software package.

[0182] In the disclosed embodiment, after the audio device is connected to the network and has the ability to communicate with the server, the audio device sends an acoustic download request to the server, so that in step S301, the server receives the acoustic parameter download request sent by the audio device. The audio device is connected to the network, which can be achieved by the audio device itself based on a preset network password when searching for the network; or it can be based on other terminal devices (such as mobile phones, tablet computers) that communicate with the audio device. After the terminal device scans the audio device to be connected to the network, the network name and password are sent to the audio device through Wi-Fi or Bluetooth or other communication methods through the network name and password entered by the user, so that the audio device is connected to the network based on the network name and password; after the audio device is connected to the network, it has the ability to communicate with the server.

[0183] After the audio device is connected to the network, the embodiment of the present disclosure can send an acoustic parameter download request to the server in a timely manner, or send an acoustic parameter download request to the server based on a preset timing, etc., and the embodiment of the present disclosure is not limited to this; wherein the preset timing can be a user-defined time, or it can be a time when the audio device is less frequently used, such as at night.

[0184] In step S302, after receiving the acoustic parameter download request, the server feeds back the acoustic parameter to the audio device that sent the acoustic parameter download request, so that after receiving the acoustic parameter, the audio device sets the acoustic parameter to the audio application in the audio device using the preset software package. The acoustic parameter includes at least one of the following: a gain parameter of an audio input signal, an EQ equalizer algorithm parameter of an audio output signal, and a DRC dynamic range control parameter.

[0185] In addition, the acoustic parameters fed back by the server of the embodiment of the present disclosure may be associated with a version number, an identifier of an audio device, etc., wherein the identifier of the audio device may include a model number and a serial number of the audio device. The audio device may be uniquely identified by the identifier of the audio device, and the acoustic parameters of different versions of the audio device may be distinguished by the version number.

[0186] It can be understood that in the scenario of setting the acoustic parameters of an audio device, compared to the method of solidifying the acoustic parameters in the server into the software package, which requires the development and maintenance of the entire software package, the embodiment of the present disclosure decouples the acoustic parameters from the software package, and the software package is set in the audio device. The server only needs to develop and maintain the acoustic parameters. After the audio device is connected to the network, the server feeds back the acoustic parameters according to the acoustic parameter download request, so that the audio device uses the preset software package to set the acoustic parameters to the audio application in the audio device. By maintaining the acoustic parameters on the server side, the audio device side does not need to update and maintain the software package, which greatly reduces the development and maintenance costs. In addition, compared with the entire software package, the acoustic parameters have a smaller number of bytes, and downloading and setting the acoustic parameters from the server is more imperceptible, thereby improving the user experience by silently updating the acoustic parameters in a way that is more imperceptible to the user.

[0187] In some embodiments, the receiving an acoustic parameter download request sent by an audio device includes:

[0188] In response to the acoustic parameter update, sending an acoustic parameter update notification to the audio device;

[0189] The acoustic parameter download request sent by the audio device according to the acoustic parameter update notification is received.

[0190] In the disclosed embodiment, after the acoustic parameters in the server are updated, an acoustic parameter update notification is sent to the audio device; wherein, the acoustic parameter update in the server may be that the acoustic engineer updates the acoustic parameters stored in the server to the calibrated acoustic parameters after adjustment; or it may be that based on a preset function, the currently stored acoustic parameters are processed and updated to the processed acoustic parameters; wherein the preset function may be a function of the change of the parameter value of the acoustic parameter over time obtained based on multiple test fittings.

[0191] After receiving the acoustic parameter update notification sent by the server, the audio device of the embodiment of the present disclosure sends an acoustic parameter download request to the server; the server feeds back the updated acoustic parameters to the audio device according to the acoustic parameter download request, so that the audio device sets the updated acoustic parameters to the audio application in the audio device using the preset software package. Since the updated acoustic parameters are usually more compatible with the acoustic morphology of the audio device, the audio device can provide the user with a better acoustic experience based on the updated acoustic parameters in a timely manner.

[0192] In some embodiments, the acoustic parameter is associated with a version number; the method further comprises:

[0195] In response to the acoustic parameter update, sending an acoustic parameter update notification to the audio device includes:

[0196] In response to the version number of the acoustic parameter stored in the server being inconsistent with the version number of the acoustic parameter currently used by the audio device, an acoustic parameter update notification is sent to the audio device.

[0197] In the embodiment of the present disclosure, the acoustic parameters stored in the server and the acoustic parameters stored in the audio device are associated with version numbers. The server of the embodiment of the present disclosure obtains the version number of the acoustic parameters currently used by the audio device by communicating with the audio device, or obtains the version number of the acoustic parameters used by the audio device recorded by the server.

[0198] In the embodiment of the present disclosure, the server determines whether the version number of the acoustic parameters currently used by the audio device is consistent with the version number of the acoustic parameters stored in the server. If they are consistent, it indicates that the audio device is currently using the latest version of the acoustic parameters and does not need to be upgraded. If they are inconsistent, it indicates that the audio device is not currently using the latest version of the acoustic parameters, so the server sends an acoustic parameter update notification to the audio device, and after the audio device sends an acoustic parameter download request to the server based on the acoustic parameter update notification, the version number recorded in the server and the associated acoustic parameters are fed back to the audio device.

[0199] In addition, after the server feeds back the acoustic parameters to the audio device, the server may also update the version number of the recorded acoustic parameters used by the audio device.

[0200] It can be understood that in the embodiment of the present disclosure, when the version number of the acoustic parameters stored in the server is inconsistent with the version number of the acoustic parameters currently used by the audio device, the server sends an acoustic parameter update notification to the audio device, so that the audio device downloads the updated acoustic parameters, which can increase the necessity for the audio device to download and update the acoustic parameters.

[0201] In some embodiments, the acoustic parameter download request carries an identifier of the audio device; and feeding back the acoustic parameter to the audio device according to the acoustic parameter download request includes:

[0202] According to the acoustic parameter download request, the acoustic parameter corresponding to the identifier of the audio device is fed back to the audio device.

[0205] After receiving the acoustic parameter download request sent by the audio device, the server of the embodiment of the present disclosure searches for the acoustic parameter corresponding to the identifier of the audio device in the stored acoustic parameters, and feeds back the acoustic parameter corresponding to the identifier of the audio device to the audio device. Through this solution, the accuracy of the feedback acoustic parameter can be improved, and the convenience of maintaining the acoustic parameters of different audio devices on the server side can be improved.

[0206] In some embodiments, the acoustic parameter download request carries an encrypted identifier of the audio device; and feeding back the acoustic parameter corresponding to the identifier of the audio device to the audio device according to the acoustic parameter download request includes:

[0207] Decrypting the encrypted identifier of the audio device according to the acoustic parameter download request;

[0208] The acoustic parameter corresponding to the decrypted identifier is fed back to the audio device.

[0209] In the disclosed embodiment, the acoustic parameter download request sent by the audio device to the server carries an encrypted identifier of the audio device; wherein the encrypted identifier can be obtained by encrypting the identifier by the audio device using a symmetric encryption algorithm, an asymmetric encryption algorithm, a hash algorithm, etc.

[0210] After the acoustic parameter download request sent by the audio device to the server in the disclosed embodiment carries the encrypted identifier of the audio device, the server decrypts the encrypted identifier of the audio device according to the acoustic parameter download request, and feeds back the acoustic parameters corresponding to the decrypted identifier to the audio device. Among them, based on the same agreed key, after the audio device encrypts the identifier using the key, the server decrypts the identifier based on the key; for example, if the encrypted identifier is obtained by encrypting the identifier using the private key of the identifier by the audio device, the server decrypts the identifier based on the public key corresponding to the private key. Through this solution, the confidentiality of the acoustic parameters in the audio device's request to download the server can be improved, and the communication security level is relatively high.

[0211] In some embodiments, feeding back the acoustic parameter to the audio device according to the acoustic parameter download request includes:

[0212] Feedback the encrypted acoustic parameters to the audio device according to the acoustic parameter download request; wherein the encrypted acoustic parameters are used by the audio device to set the decrypted acoustic parameters to the audio application in the audio device using the preset software package after the audio device decrypts them.

[0213] In the disclosed embodiment, the server encrypts the stored acoustic parameters using the aforementioned symmetric encryption algorithm, asymmetric encryption algorithm, hash algorithm, etc., and thereby feeds back the encrypted acoustic parameters to the audio device based on the acoustic parameter download request sent by the audio device; the audio device decrypts the encrypted acoustic parameters after receiving them, and uses a preset software package to set the decrypted acoustic parameters to the audio application in the audio device.

[0214] Among them, based on the agreed same key, after the server uses the key to encrypt the acoustic parameters, the audio device can decrypt the acoustic parameters based on the key; for example, if the encrypted acoustic parameters are obtained by the server using the parameter public key to encrypt the acoustic parameters, the audio device can decrypt the acoustic parameters based on the parameter private key corresponding to the parameter public key. Through this solution, the confidentiality of the acoustic parameters fed back by the server to the audio device can be improved, and the communication security level is relatively high.

[0215] In some embodiments, the method further comprises:

[0216] Receiving a verification request sent by the audio device; wherein the verification request carries an identification of the audio device;

[0217] Feedback a verification result to the audio device according to the identifier of the audio device;

[0220] In the disclosed embodiment, after the audio device is connected to the network, it sends a verification request carrying the identification of the audio device to the server. After receiving the verification request sent by the audio device, the server feeds back the verification result to the audio device according to the identification of the audio device; wherein, when the identification of the audio device is consistent with the authorized device identification pre-recorded in the server, or the partial identification of the audio device (such as the first 4 bytes of the identification) is consistent with the authorized identification header pre-recorded in the server, it indicates that the verification is passed, so that the server can receive the acoustic parameter download request sent by the audio device, and feed back the acoustic parameters to the audio device according to the acoustic parameter download request.

[0221] It can be understood that in the embodiment of the present disclosure, the server determines the verification result based on the verification request sent by the audio device, and when the verification result indicates that the verification is passed, receives the acoustic parameter download request sent by the audio device, so that the audio device that has passed the verification can download the acoustic parameters from the server, which can reduce the information leakage and network communication overhead caused by the downloading of acoustic parameters by the audio device that has not passed the verification.
