Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a noise cancellation method according to a first embodiment of the present invention.
While a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in a different order than presented herein.
The noise elimination method comprises the following steps:
step S10, when detecting a start instruction of the audio gain adjustment, the smart television system determines parameter information of the terminal device connected to the smart television system according to the start instruction, and determines at least one target terminal device corresponding to the audio gain adjustment in the terminal device according to the parameter information, where the number of the terminal devices includes at least one.
When a start instruction of the sound gain adjustment is detected, the intelligent television system determines parameter information of terminal equipment corresponding to the start instruction, wherein the parameter information comprises audio data and a sound gain value, and the terminal equipment is the terminal equipment in the same intelligent wireless network as the intelligent television system, so that the number of the terminal equipment at least comprises one.
Then, the smart television system may determine at least one target terminal device corresponding to the sound gain adjustment according to the parameter information of the terminal device, where the target terminal device is an object to be adjusted in the sound gain, that is, a terminal device having howling noise, that is, the smart television system determines which terminal device or devices having howling noise are according to the parameter information of each terminal device.
It should be noted that the start instruction of the sound gain adjustment may be automatically triggered according to the actual situation, for example, when the frequency or loudness of the noise is greater than the preset frequency or loudness; or the smart television system may be triggered when receiving a start instruction manually input by a user, for example, when a terminal device generates a howling noise, the user remotely controls the start, and the like.
Specifically, the process of determining the target terminal device includes:
step a, the intelligent television system detects the type of the terminal equipment according to a starting instruction;
in an embodiment, the smart television system detects types of all terminal devices connected with the smart television system according to a start instruction, wherein the type of the device refers to whether the terminal device has a touch screen, that is, the smart television system specifically detects whether the terminal device carries the touch screen or does not carry the touch screen, such as a smart sound box without the touch screen; or a television or a PC (Personal Computer) carrying a touch screen.
B, if the terminal equipment carries a touch screen, the intelligent television system acquires the click times of the terminal equipment within a first preset time length;
step c, if the target click times exist in the click times, the intelligent television system acquires first audio data and a first audio gain value of the terminal equipment corresponding to the target click times, wherein the target click times are larger than a first preset number set by the intelligent television system;
if the current terminal equipment carries the touch screen, the intelligent television system acquires the click times of the current terminal equipment within a first preset time length, and detects whether the click times are greater than the first preset time length set by the intelligent television system, wherein the first preset time length is set in the intelligent television system according to actual requirements, such as 1 minute and the like; the first preset number is the average number of times the touch screen is clicked within a preset unit time (unit: minute).
It can be understood that the terminal device connected to the smart television system includes at least one terminal device, and therefore, the number of clicks of the user on the touch screen of the terminal device also includes at least one, if there are 2 terminal devices at present, which are a first terminal device and a second terminal device, the first terminal device corresponds to one number of clicks, the second terminal device corresponds to one number of clicks, the number of clicks at this time is two, the target number of clicks is one of which the number of clicks is greater than the first preset number set by the smart television system, and if the number of clicks corresponding to the first terminal device is greater than the first preset number set by the smart television system, the number of clicks corresponding to the first terminal device is the target number of clicks, and the like.
If the click times are detected to be larger than the first preset times, the intelligent television system obtains parameter information of the terminal device corresponding to the click times, wherein the parameter information comprises first audio data and a first sound gain value.
And d, determining target terminal equipment corresponding to the sound gain adjustment according to the first audio data and the first sound gain value.
And comparing the first audio data with the first sound gain value, wherein the first audio data is the audio data received by the smart television system through an audio collection device in the terminal equipment, such as a microphone, an earphone and the like. And finally, determining a target terminal device corresponding to the sound gain adjustment according to the comparison result, namely, determining the terminal device which is about to eliminate the howling noise from at least one terminal device as the target terminal device according to the audio data of each terminal device and the size relation of the sound gain value by the intelligent television system.
Further, the process of determining the target terminal device corresponding to the tone gain adjustment includes:
step e, the intelligent television system detects whether target audio data exist in the first audio data, wherein the sound gain value of the target audio data is larger than or equal to half of the first sound gain value;
and f, if the target audio data exists, the intelligent television system determines that the terminal equipment corresponding to the target audio data is the target terminal equipment corresponding to the sound gain adjustment.
Specifically, the smart television system detects whether target audio data with a sound gain value greater than or equal to half of a first sound gain value exists in the first audio data, and if it is detected that the target audio data exists in the first audio data, the smart television system determines that the terminal device corresponding to the target audio data is a target terminal device corresponding to sound gain adjustment, that is, the sound gain value corresponding to the current audio data is greater than or equal to half of a preset first sound gain value, and determines that the current audio data is the target audio data, and the corresponding terminal device is the target terminal device.
And step S20, the smart television system obtains the corresponding voice decibel value through the audio collection device in the target terminal equipment, obtains the sound gain value corresponding to the target terminal equipment, and determines the target sound gain value corresponding to the target terminal equipment according to the voice decibel value and the sound gain value.
The intelligent television system acquires voice through an audio collecting device (a microphone and an earphone) in the target terminal equipment, determines a corresponding voice decibel value according to the voice, then acquires a voice gain value corresponding to the target terminal equipment, detects the relation between the voice decibel value and a preset decibel value range in the intelligent television system, starts a corresponding adjusting mode according to a detection result, adjusts the voice gain value in the target terminal equipment through the corresponding adjusting mode, and determines a target voice gain value corresponding to the target terminal equipment, wherein the preset decibel range can be set according to actual conditions, such as 60-80 decibels.
Specifically, the process of determining the target sound gain value corresponding to the target terminal device according to the decibel of the human voice and the sound gain value includes:
step g, if the target terminal device carries a touch screen, the intelligent television system detects whether the human voice decibel value is within a first preset decibel value range set by the intelligent television system;
step h, if yes, the intelligent television system obtains the number of users corresponding to the touch screen and acquired by the target terminal device through the image acquisition device;
and i, the intelligent television system determines a target sound gain value corresponding to the target terminal device according to the sound gain value and the number of users.
Specifically, if the target terminal device is detected to be a portable touch screen, the smart television system detects whether the human voice decibel value is within a first preset decibel value range set by the smart television system, and if so, the smart television system starts an extremely fast sound gain reduction adjustment mode, that is, the smart television system obtains the number of users in front of the touch screen, which are shot by the target terminal device through an image acquisition device (a camera or a video camera) in the target terminal device, and calculates a target sound gain value corresponding to the target terminal device through a calculation method corresponding to the extremely fast sound gain reduction adjustment mode according to the number of users in front of the touch screen and the sound gain value corresponding to the target terminal device.
The first preset decibel range and the audio gain extreme speed reduction adjustment mode are set in the smart television system according to actual conditions, and this embodiment is not limited.
Further, the method for calculating the sound gain extreme speed reduction adjustment mode comprises the following steps:
step j, the intelligent television system reduces the sound gain value by half to obtain a corresponding third sound gain value, and calculates the sum of the number of users and the third sound gain value to obtain a corresponding fourth sound gain value;
and k, the intelligent television system calculates the product of the fourth sound gain value and a preset sound gain ratio to obtain a target sound gain value corresponding to the target terminal equipment, wherein the preset sound gain ratio is determined by the intelligent television system according to the number of users.
Specifically, the intelligent television system halves the sound gain value corresponding to the target terminal device to obtain a third sound gain value corresponding to the target terminal device, then adds and sums the third sound gain value and the number of users before touching the screen, determines the obtained sum value as a fourth sound gain value corresponding to the target terminal device, then multiplies the fourth sound gain value by a first preset sound gain proportion set by the intelligent television system according to the number of users, and determines the obtained product as the target sound gain value corresponding to the target terminal device.
The preset sound gain proportion is determined by the smart television system according to the number of users before touching the screen, the preset sound gain proportions corresponding to different numbers of users are different, in specific implementation, a mapping table of the number of users and the preset sound gain proportion can be set according to actual conditions, and after the number of users before touching the screen is determined by the smart television system, the corresponding preset sound gain proportion can be determined by searching the mapping table.
And step S30, the intelligent television system adjusts the audio power corresponding to the target terminal equipment according to the target sound gain value so as to eliminate the noise in the target terminal equipment.
And the intelligent television system adjusts the audio power corresponding to the target terminal equipment according to the target sound gain value, so that the target terminal equipment is reduced due to the excessively strong audio power, and howling noise is inhibited.
Further, the noise canceling method further includes:
step l, if the terminal equipment does not carry the touch screen, the intelligent television system acquires the voice interaction times of the terminal equipment within a second preset time length;
step m, if the target interaction times exist in the voice interaction times, the intelligent television system acquires second audio data and a second audio gain value of the terminal equipment corresponding to the target interaction times;
and n, the intelligent television system determines the target terminal equipment corresponding to the sound gain adjustment according to the second audio data and the second sound gain value.
Specifically, if the smart television system detects that the terminal device does not carry the touch screen, the smart television system obtains the number of voice interactions within a second preset time period through an audio collecting device (a microphone, an earphone) in the target terminal device, where the number of voice interactions may be defined according to an actual situation, for example, the number of voice interactions is recorded once in an interaction process with the user from an awake stage to a sleep stage of the terminal device, or the number of voice interactions is recorded once when the terminal device responds to the voice of the user every time, and the second preset time period may also be defined according to an actual situation, for example, a day, and the number of voice interactions with the user within a day that the smart television system obtains the terminal device is also several times.
And then, the intelligent television system detects whether a target frequency greater than a second preset frequency set by the intelligent television system exists in the voice interaction frequency. If the target audio data exists, the intelligent television system obtains second audio data and a second audio gain value in the terminal equipment corresponding to the target times, detects whether the target audio data corresponding to a half of the second audio gain value exists in the second audio data, and if the target audio data exists in the second audio data, the intelligent television system determines that the terminal equipment corresponding to the target audio data is the target terminal equipment corresponding to the audio gain adjustment.
It can be understood that, since the terminal device includes at least one, the number of times of voice interaction between the user and the terminal device also includes at least one, when the number of times of voice interaction is one, the current number of times of voice interaction is directly compared with a second preset number of times set by the smart television system, and if the current number of times of voice interaction is greater than the second preset number of times set by the smart television system, the current number of times of voice interaction is a target number of times of interaction; when the number of voice interaction times is multiple, comparing each voice interaction time with a second preset time set by the intelligent television system one by one, and determining whether the number of voice interaction times is larger than the second preset time set by the intelligent television system or not, namely determining the target interaction times.
If 2 terminal devices are currently provided, namely a terminal device A and a terminal device B, the terminal device A corresponds to one voice interaction frequency, the terminal device B corresponds to one voice interaction frequency, the voice interaction frequency at the moment is two, the target interaction frequency is the voice interaction frequency which is larger than the second preset frequency set by the intelligent television system, and if the voice interaction frequency corresponding to the terminal device A is larger than the second preset frequency set by the intelligent television system, the voice interaction frequency corresponding to the terminal device A is the target interaction frequency and the like.
In this embodiment, when a start instruction of the audio gain adjustment is detected, parameter information of terminal equipment connected to the smart television system is determined according to the start instruction, and at least one target terminal equipment corresponding to the audio gain adjustment is determined in the terminal equipment according to the parameter information, wherein the number of the terminal equipment at least includes one; acquiring a corresponding voice decibel value through an audio collection device in target terminal equipment, acquiring a voice gain value corresponding to the target terminal equipment, and determining a target voice gain value corresponding to the target terminal equipment according to the voice decibel value and the voice gain value; according to the method, the audio power corresponding to the target terminal equipment is adjusted according to the target sound gain value so as to eliminate the noise in the target terminal equipment.
Further, a second embodiment of the noise canceling method of the present invention is provided.
The second embodiment of the noise canceling method differs from the first embodiment of the noise canceling method in that the noise canceling method includes:
step o, if the target terminal device does not carry the touch screen, the intelligent television system detects whether the voice decibel value is within a second preset decibel value range set by the intelligent television system;
step p, if yes, the intelligent television system calculates the product of the sound gain value and a second preset proportion set by the intelligent television system to obtain a corresponding fifth sound gain value, and determines a current sound gain value corresponding to the target terminal equipment;
step q, the intelligent television system detects whether the current sound gain value is larger than a fifth sound gain value;
step r, if the current sound gain value is larger than the fifth sound gain value, the intelligent television system subtracts the human sound decibel value from the current sound gain value to obtain a sixth sound gain value, and detects whether the sixth sound gain value is within a third preset decibel range set by the intelligent television system;
and step s, if the sixth sound gain value is detected to be out of the third preset decibel range, the intelligent television system adjusts the sixth sound gain value to be within the third preset decibel range, and determines the adjusted sixth sound gain value as a target sound gain value corresponding to the target terminal equipment.
Specifically, if the target terminal device is detected to be a terminal device not carrying a touch screen, the smart television system detects whether the human voice decibel is within a second preset decibel range set by the smart television system, if the human voice decibel is detected to be within the second preset decibel range, the smart television system starts a sound gain extremely-fast reduction adjustment mode, namely, the smart television system obtains a sound gain value corresponding to the target terminal device, calculates a product of the sound gain value corresponding to the target terminal device and a second preset proportion set by the smart television system to obtain a corresponding fifth sound gain value, then determines a current sound gain value corresponding to the target terminal device, detects whether the current sound gain value is greater than the fifth sound gain value, if the current sound gain value is greater than the fifth sound gain value, the smart television system subtracts the human voice decibel from the current sound gain value, and obtaining a corresponding sixth sound gain value, then detecting whether the sixth sound gain value is within a third preset decibel range set by the intelligent television system, and if the sixth sound gain value is detected to be within the third preset decibel range, determining the sixth sound gain value as a target sound gain value corresponding to the target terminal equipment by the intelligent television system. If the sixth sound gain value is outside the third preset decibel range, the intelligent television system multiplies the sixth sound gain value by a preset proportion, adjusts the sixth sound gain value to be within the third preset decibel range, and determines the adjusted sixth sound gain value as a target sound gain value corresponding to the target terminal equipment.
If the target terminal device is detected not to carry the touch screen, the target sound gain value corresponding to the target terminal device is determined according to the current sound gain value, the sound gain value and the human sound decibel, and the certainty of the target sound gain value is improved.
