The Memory 1005 may be a Random Access Memory (RAM) or a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.

As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a frequency response parameter adjustment program.
In the frequency response parameter adjusting apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 of the frequency response parameter adjusting device of the present invention may be disposed in the frequency response parameter adjusting device, and the frequency response parameter adjusting device calls the frequency response parameter adjusting program stored in the memory 1005 through the processor 1001 and executes the frequency response parameter adjusting method provided by the embodiment of the present invention.
Based on the above frequency response parameter adjusting device, an embodiment of the present invention provides a frequency response parameter adjusting method, and referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of the frequency response parameter adjusting method according to the present invention.
In this embodiment, the frequency response parameter adjusting method includes the following steps:
step S10: the method comprises the steps of obtaining current sound signals collected by remote control equipment, and carrying out signal separation on the current sound signals to obtain target full-band sound signals.
It should be noted that the execution subject of the embodiment may be a computing service device with data processing, network communication and program running functions, such as a mobile phone, a tablet computer, a personal computer, etc., or an electronic device or a television set, etc., capable of implementing the above functions. The present embodiment and each of the following embodiments will be described below by taking the television set as an example.
The remote control device may be a device with a remote control function, for example, a remote controller corresponding to a television, a mobile phone, or a smart audio device. The current sound signal may be a sound signal in the environment in which the remote control device is currently located. The signal separation of the current sound signal may be to separate a noise signal from the current sound signal, that is, to remove a noise signal from a terminal of the current sound signal, so as to obtain a target full-band sound signal.
It should be understood that the current sound signal collected by the remote control device may be a sound signal emitted by a sound generating device, such as a television, and when a user controls the television to start playing a multimedia file through the remote control device, the television starts adjusting the frequency response parameter, and the adjusting process may be sending a preset instruction to start collecting sound to the remote control device, so that the remote control device starts collecting sound in the environment after receiving the instruction to start collecting sound and feeds back the collected sound to the television. The sound in the environment comprises sound emitted by the television, so that the television adjusts the frequency response parameters according to the sound fed back by the remote control device. The adjustment of the frequency response parameters can be dynamically adjusted according to different positions of the user, so that the sound of the television heard by the user is more in line with the expectation of the user, and the experience of the user is improved.
Further, in order to make the adjustment result of the frequency response parameter more desirable to the user, step S10 includes: acquiring a current sound signal acquired by remote control equipment; extracting an environment sound signal in the current sound signal; and carrying out full-band sound signal separation on the environment sound signal to obtain a target full-band sound signal.
It should be noted that the ambient sound signal may be a sound signal containing sound information emitted by a television. The separating the full-band sound signal from the environment sound signal may be removing a noise signal from the environment sound signal to obtain a sound signal collected without the noise signal and emitted by the television, that is, a target full-band sound signal.
In specific implementation, after the television receives a control instruction sent by a user through the remote control device, the audio processing unit of the television sends a 20-20Khz full-band sound signal to the sound generating unit so that the sound generating unit can generate sound, and sends a preset sound collecting instruction to the remote control device so that the remote control device starts to collect a sound signal in an environment after receiving the sound collecting instruction and feeds the sound signal back to the television. The television performs signal separation on the received sound signals, namely noise signals in the environment are removed, and target full-band sound signals are obtained.
Step S20: and extracting frequency response parameters corresponding to the target full-band sound signals.
It should be noted that the frequency response parameter may be details of the sound within the frequency response range, and is generally represented by a frequency response curve.
In a specific implementation, the audio processing unit of the television extracts, according to the target full-band sound signal, a frequency response parameter corresponding to the target full-band sound signal, or generates a frequency response curve corresponding to the target full-band sound signal.
Step S30: and determining a frequency response parameter difference value according to the frequency response parameter and a preset frequency response parameter.
It should be noted that the preset frequency response parameter may be a preset frequency response parameter that meets the user's desire. The frequency response parameter difference may be a difference between the frequency response parameter and a preset frequency response parameter.
In specific implementation, the television calculates a difference value between the frequency response parameter and a preset frequency response parameter to obtain a frequency response parameter difference value.
Step S40: and adjusting the current frequency response parameter based on the frequency response parameter difference value.
It should be noted that, adjusting the current frequency response parameter based on the frequency response parameter difference may be adjusting the current frequency response parameter so that the difference between the current frequency response parameter and the preset frequency response parameter is smaller than a preset frequency response parameter difference threshold.
Further, in order to make the adjusted frequency response parameter more suitable for the user' S desire, the step S40 includes:
step S401: judging whether the frequency response parameter difference is larger than a preset frequency response parameter difference or not;
step S402: and when the frequency response parameter difference is larger than the preset frequency response parameter difference, adjusting the current frequency response parameter through an equalizer, so that the difference between the adjusted frequency response parameter and the preset frequency response parameter is smaller than the preset frequency response parameter difference.
It should be noted that the preset frequency response parameter difference may be a preset frequency response parameter difference, which may ensure that if the frequency response parameter difference is less than or equal to the preset frequency response parameter difference, it indicates that the sound of the television heard by the user at the current position may meet the user's expectation, and a good sound effect is achieved.
Further, in order to improve the experience of the user, the step S401 further includes: if the frequency response parameter difference is smaller than or equal to the preset frequency response parameter difference, judging that the current frequency response parameter is in a normal frequency response parameter range, and stopping full-band sound signal separation; recording the stop time length for stopping the full-band sound signal separation, and judging whether the stop time length reaches the preset time length; and returning to the step of acquiring the current sound signal acquired by the remote control equipment and carrying out signal separation on the current sound signal to acquire the target full-band sound signal when the stop duration reaches the preset duration.
The stopping of the full-band sound signal separation may be stopping of the adjustment of the frequency response parameter. The stopping duration may be a duration from the current time after the adjustment of the frequency response parameter is stopped, that is, the adjustment may be started again at a preset time interval after the frequency response parameter is adjusted once, so as to avoid that the frequency response parameter adjusted last time is not suitable for the current position of the user due to the movement of the user, and needs to be adjusted again according to the current position of the user, so as to ensure that the frequency response parameter can be dynamically adjusted according to the position of the user after the user moves the position.
It should be understood that even if the sound signals emitted by the television are completely consistent, the current sound signals collected by the remote control device are different in different environmental locations, and therefore, the frequency response parameters of the sound signals collected by each location need to be adjusted in each location, so that the frequency response parameters of the sound signals collected by each location meet the target frequency response parameters.
In specific implementation, when the frequency response parameter difference is greater than the preset frequency response parameter difference, an equalizer curve parameter of the power amplifier is called, and the frequency response parameter is calibrated, so that the difference between the adjusted frequency response parameter and the preset frequency response parameter is smaller than the preset frequency response parameter difference. And after the frequency response parameters are adjusted, acquiring the current sound signals collected by the remote control equipment again, and returning to the step S10 until the frequency response parameters of the current sound signals meet the target frequency response parameters, namely the frequency response parameter difference is smaller than or equal to the preset frequency response parameter difference. This step may be used to verify whether the adjusted frequency response parameter meets the target frequency response parameter. If the difference value of the frequency response parameters is smaller than or equal to the preset frequency response parameter difference value, judging that the current frequency response parameters are in a normal frequency response parameter range, and temporarily stopping full-band sound signal separation in order to save the energy consumption of the system; recording the stop time length for stopping the full-band sound signal separation, and judging whether the stop time length reaches the preset time length; and returning to the step of acquiring the current sound signal acquired by the remote control equipment and carrying out signal separation on the current sound signal to acquire the target full-band sound signal when the stop duration reaches the preset duration.
The method comprises the steps of obtaining a current sound signal collected by remote control equipment, and carrying out signal separation on the current sound signal to obtain a target full-band sound signal; extracting frequency response parameters corresponding to the target full-band sound signals; determining a frequency response parameter difference value according to the frequency response parameter and a preset frequency response parameter; and adjusting the current frequency response parameter based on the frequency response parameter difference value. In the embodiment, the current sound signal is acquired through the remote control device, the target full-band sound signal is acquired according to the current sound signal, and then the current frequency response parameter is adjusted according to the target full-band sound signal. Compared with the existing mode of adjusting the sound signals of the sound production equipment picked up through the sound pickup module, the sound signals are collected through the remote control equipment capable of basically reflecting the position of the user, so that the picked-up sound signals can feed back the sound field environment where the user is located, and the sound after the frequency response parameters are adjusted can better meet the expectation of the user.
Referring to fig. 3, fig. 3 is a flowchart illustrating a frequency response parameter adjusting method according to a second embodiment of the present invention.
Based on the first embodiment, in this embodiment, after step S40, the method further includes:
step S50: the method comprises the steps of obtaining the figure information in the current environment through a preset detection unit, and determining the number of users according to the figure information.
It should be noted that the preset detection unit may be a detection device including a human body infrared detection device, a microwave detection device, and/or a radar detection device, and the like, and is used for detecting information such as the number of users and the user position in a preset environment range, that is, the person information. The preset environment range may be an environment range in which the television is located, for example, in a home, the environment range may be set to a living room or the like, and in an outdoor, the environment range may be set to a range in which a certain viewing effect can be ensured centering on the television. The number of the users is the number of the people in the set environment range.
Further, in order to enable each user to have a sound signal at a position thereof satisfying a preset frequency response parameter in the case of multiple users, after step S40, the method further includes: determining the position information of the remote control equipment corresponding to the adjusted frequency response parameters; determining a target position according to the position information of the remote control equipment; and associating the target position with the adjusted frequency response parameters, and storing the association result.
It should be noted that the adjusted frequency response parameter may be a frequency response parameter that satisfies a preset frequency response parameter after adjustment, or may be a frequency response parameter that directly satisfies the preset frequency response parameter without adjustment when the frequency response parameter is adjusted, that is, when the frequency response parameter is adjusted, a frequency response parameter difference is smaller than or equal to a preset frequency response parameter difference. The position information of the remote control device may be information such as a position where the remote control device corresponding to the adjusted frequency response parameter is located, and the target position may be a position where the remote control device corresponding to the adjusted frequency response parameter is located. The associating of the target position with the adjusted frequency response parameter may be associating the position of the remote control device with the adjusted frequency response parameter that satisfies a preset frequency response parameter after being adjusted at the position.
In a specific implementation, the television acquires the personal information within a set range through detection equipment such as a human body infrared detection device, a microwave detection device and/or a radar detection device, and determines the number of users according to the personal information.
Step S60: and judging whether the number of the users is larger than the preset number of the users.
It should be noted that the preset number of users may be a preset number of characters.
Step S70: and when the number of the users is larger than the preset number of the users, acquiring the current position of each user according to the character information.
It should be noted that the current location of each user may be a location of a user in a preset environment range. The coordinates of the position of each user can be simulated by using the television as a reference point.
Step S80: and adjusting the current frequency response parameters according to the current position of each user.
It should be noted that, the adjusting the current frequency response parameter according to the current position of each user may be fitting the current position of each user according to the current position of each user, that is, obtaining a center position according to the position of each user, and adjusting the frequency response parameter according to the current sound signal fed back by the center position, or adjusting the frequency response parameter according to the adjusted frequency response parameter corresponding to the center position in the correlation result. For example, if there are two users, the position of the midpoint between the two users is used as the position for adjusting the frequency response parameter, and if the two users are located together, the position of one of the users is directly used for adjusting the frequency response parameter. And if the number of the users is multiple, acquiring the midpoint positions of the multiple users, and adjusting the frequency response parameters according to the positions.
Further, in order to enable the sound signal of each user at the position thereof to satisfy the preset frequency response parameter, the step S80 includes: acquiring target frequency response parameters corresponding to the current positions of the users according to the correlation results; calculating an average frequency response parameter according to the target frequency response parameter; and adjusting the current frequency response parameter according to the average frequency response parameter.
It should be noted that the target frequency response parameter may be a frequency response parameter that satisfies a preset frequency response parameter after being adjusted before, corresponding to the current position of each user, obtained by querying the association result. The average frequency response parameter may be an average value of target frequency response parameters corresponding to each user, so as to obtain an average frequency response parameter. And adjusting the current frequency response parameter according to the average frequency response parameter.
In specific implementation, the television acquires a target frequency response parameter corresponding to the current position of each user from the correlation result according to the position of each user acquired by the detection unit, averages the target frequency response parameters to obtain an average frequency response parameter, and adjusts the current frequency response parameter according to the average frequency response parameter.
In the embodiment, the figure information in the current environment is acquired through a preset detection unit, and the number of users is determined according to the figure information; judging whether the number of the users is larger than a preset number of the users; when the number of the users is larger than the preset number of the users, the current position of each user is obtained according to the character information; acquiring target frequency response parameters corresponding to the current positions of the users according to the correlation results; calculating an average frequency response parameter according to the target frequency response parameter; and adjusting the current frequency response parameter according to the average frequency response parameter. In the present embodiment, in the case of multiple users, the average frequency response parameter is calculated from the adjusted frequency response parameters at the positions of the respective users. And adjusting the current frequency response parameter according to the average frequency response parameter. Under the condition of multiple users, the sound emitted by the television can be well heard at the position where each user is located as far as possible, and the experience of the users is improved.
