Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a flow chart illustrating a first embodiment of the noise cancellation method according to the present invention.
The embodiments of the present invention provide embodiments of methods of noise cancellation, it being noted that although a logic sequence is shown in the flow chart, under certain data, the steps shown or described may be performed in a different order than that shown or described herein.
The noise cancellation method includes:
step S10, when a starting instruction of sound gain adjustment is detected, the intelligent television system determines parameter information of terminal equipment connected with the intelligent television system according to the starting instruction, and determines at least one target terminal equipment corresponding to the sound gain adjustment in the terminal equipment according to the parameter information, wherein the number of the terminal equipment at least comprises one.
When a starting instruction of sound gain adjustment is detected, the intelligent television system determines parameter information of terminal equipment corresponding to the starting instruction, wherein the parameter information comprises audio data and sound gain values, and the terminal equipment is 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.
And then, the intelligent television system can determine at least one target terminal device corresponding to the sound gain adjustment according to the parameter information of the terminal device, wherein the target terminal device is a target to be adjusted for the sound gain, namely, the terminal device with howling noise, namely, the intelligent television system judges which terminal device or which terminal devices with 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 triggered automatically according to the actual situation, for example, when the frequency or loudness of the noise is greater than a preset frequency or loudness; the intelligent television system can also be triggered when receiving a starting instruction manually input by a user, such as remote control starting of the user when howling noise occurs in the terminal equipment.
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 the starting instruction;
in an embodiment, the smart television system detects types of all terminal devices connected with the smart television system according to the start instruction, wherein the types of the devices refer to the types of the terminal devices with no touch screen, that is, the smart television system specifically detects whether the terminal devices carry a touch screen or do not carry a touch screen, such as a smart speaker without a touch screen, and the like; or a television or PC (Personal Computer ) carrying a touch screen, etc.
B, if the terminal equipment carries a touch screen, the intelligent television system acquires the clicking times of the terminal equipment within a first preset duration;
step c, if the target click times exist in the click times, the intelligent television system acquires first audio data and a first sound gain value of terminal equipment corresponding to the target click times, wherein the target click times are larger than first preset times set by the intelligent television system;
if the current terminal equipment carries a touch screen, the intelligent television system acquires the number of clicking times of the current terminal equipment within a first preset time period, and detects whether the number of clicking times is larger than the first preset time period set by the intelligent television system, wherein the first preset time period is set in the intelligent television system according to actual requirements, such as 1 minute and the like; the first preset number of times is an average number of times the touch screen is clicked within a preset unit time (unit: minutes).
It can be understood that the terminal device connected to the smart tv system includes at least one terminal device, so that the number of clicks of the user on the touch screen of the terminal device also includes at least one, for example, 2 terminal devices currently exist, namely, a terminal device a and a terminal device b respectively correspond to one click number, a terminal device b corresponds to one click number, two click numbers at this time are corresponding to the second terminal device b, the target click number is one of the click numbers that is greater than the first preset number set by the smart tv system, and if the click number corresponding to the terminal device a is greater than the first preset number set by the smart tv system, the click number corresponding to the terminal device a is the target click number.
If the detected clicking times are larger than the first preset times, the intelligent television system acquires parameter information of terminal equipment corresponding to the clicking 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.
The first audio data is compared with the first audio gain value, wherein the first audio data is received by the intelligent television system through an audio collecting device in the terminal equipment, such as a microphone, a headset 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 to be eliminated from the at least one terminal device, namely, 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 sound 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 greater 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 intelligent 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, if the target audio data exists in the first audio data, the intelligent television system determines that terminal equipment corresponding to the target audio data is target terminal equipment corresponding to sound gain adjustment, that is, the sound gain value corresponding to 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 target audio data, and that the terminal equipment corresponding to the current audio data is target terminal equipment.
Step S20, the intelligent television system obtains a corresponding voice decibel value through an audio collection device in the target terminal equipment, obtains a sound gain value corresponding to the target terminal equipment, and determines a 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 collection device (microphone and earphone) in the target terminal equipment, determines a corresponding voice decibel value according to the voice, 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 adjustment mode according to a detection result, and adjusts the voice gain value in the target terminal equipment through the corresponding adjustment mode so as to determine the 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 voice decibel and the sound gain value includes:
step g, if the target terminal equipment carries a touch screen, the intelligent television system detects whether the 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 acquires the corresponding user quantity before the touch screen acquired by the target terminal equipment through the image acquisition device;
and i, determining a target sound gain value corresponding to the target terminal equipment by the intelligent television system according to the sound gain value and the number of users.
Specifically, if the target terminal equipment is detected to be carrying the touch screen, the intelligent television system detects whether the voice decibel value is within a first preset decibel value range set by the intelligent television system, if so, the intelligent television system starts a sound gain extreme speed reduction adjustment mode, namely the intelligent television system acquires the number of users before the touch screen, which are shot by the target terminal equipment through an image acquisition device (a camera and a camera) in the target terminal equipment, according to the number of users before the touch screen and the sound gain value corresponding to the target terminal equipment, and calculates the target sound gain value corresponding to the target terminal equipment through a calculation method corresponding to the sound gain extreme speed reduction adjustment mode.
The first preset db range and the audio gain speed reduction adjustment mode are set in the smart tv system according to actual situations, which is not limited in this embodiment.
Further, the calculation method corresponding to the sound gain extreme speed reduction adjustment mode comprises the following steps:
step j, the intelligent television system halving the sound gain value to obtain a corresponding third sound gain value, and calculating the sum of the number of users and the third sound gain value to obtain a corresponding fourth sound gain value;
and step k, the intelligent television system calculates the product of the fourth sound gain value and the preset sound gain proportion to obtain a target sound gain value corresponding to the target terminal equipment, wherein the preset sound gain proportion is determined by the intelligent television system according to the number of users.
Specifically, the intelligent television system halving the sound gain value corresponding to the target terminal equipment to obtain a third sound gain value corresponding to the target terminal equipment, then adding and summing the third sound gain value and the number of users before touching the screen, determining the obtained sum value as a fourth sound gain value corresponding to the target terminal equipment by the intelligent television system, multiplying 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 determining the obtained product as the target sound gain value corresponding to the target terminal equipment.
The preset sound gain ratio is determined by the intelligent television system according to the number of users in front of the touch screen, the preset sound gain ratios corresponding to different numbers of users are different, and when the intelligent television system is in practical implementation, a mapping table of the number of users and the preset sound gain ratio can be set according to actual conditions, and after the number of users in front of the touch screen is determined, the intelligent television system can determine the corresponding preset sound gain ratio 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 regulated down due to the excessively strong audio power, and howling noise is suppressed.
Further, the noise cancellation method further includes:
step l, if the terminal equipment does not carry a touch screen, the intelligent television system acquires the voice interaction times of the terminal equipment within a second preset duration;
step m, if the target interaction times exist in the voice interaction times, the intelligent television system acquires second audio data and a second sound gain value of terminal equipment corresponding to the target interaction times;
and n, determining a target terminal device corresponding to the sound gain adjustment by the intelligent television system 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 voice interaction times within a second preset duration are obtained through an audio collecting device (microphone, earphone) in the target terminal device, wherein the voice interaction times can be defined according to practical situations, such as recording the voice interaction times of the terminal device with the user in the interaction process from a wake-up stage to a sleep stage, or recording the voice interaction times of the terminal device once every time the terminal device responds to the voice of the user, and the like, and the second preset duration can also be defined according to practical situations, such as one day, or the like, that is, the smart television system obtains that the voice interaction times of the terminal device with the user in one day are several times.
And then, the intelligent television system detects whether target times larger than a second preset times set by the intelligent television system exist in the voice interaction times. If so, the intelligent television system acquires second audio data and a second sound gain value in the terminal equipment corresponding to the target times, detects whether target audio data corresponding to more than half of the second sound gain value exist in the second audio data, and if so, determines that the terminal equipment corresponding to the target audio data is the target terminal equipment corresponding to sound gain adjustment.
It can be understood that, since the terminal device includes at least one, the number of voice interactions between the user and the terminal device also includes at least one, when the number of voice interactions is one, the current number of voice interactions is directly compared with the second preset number of times set by the smart television system, and if the current number of voice interactions is greater than the second preset number of times set by the smart television system, the current number of voice interactions is the target number of interactions; when the number of voice interaction times is multiple, comparing each voice interaction time with a second preset number of times set by the intelligent television system one by one, so as to determine whether the voice interaction times larger than the second preset number of times set by the intelligent television system exist in the multiple voice interaction times, namely the target interaction times.
If there are 2 terminal devices, namely, a terminal device A and a terminal device B, respectively, the terminal device A corresponds to one voice interaction time, the terminal device B corresponds to one voice interaction time, at this time, the voice interaction time is two, the target interaction time is one of the voice interaction times which are greater than the second preset times set by the intelligent television system, if the voice interaction time corresponding to the terminal device A is greater than the second preset times set by the intelligent television system, the voice interaction time corresponding to the terminal device A is the target interaction time, and the like.
When a starting instruction of sound gain adjustment is detected, parameter information of terminal equipment connected with the intelligent television system is determined according to the starting instruction, and at least one target terminal equipment corresponding to the sound gain adjustment is determined in the terminal equipment according to the parameter information, wherein the number of the terminal equipment at least comprises one; obtaining a corresponding voice decibel value through an audio collection device in the target terminal equipment, obtaining a sound gain value corresponding to the target terminal equipment, and determining a target sound gain value corresponding to the target terminal equipment according to the voice decibel value and the sound 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, and therefore, the method can eliminate the noise of the terminal equipment by adjusting the audio power of the terminal equipment through adjusting the sound gain value, and in the process, a complex chip circuit is not required, so that the noise elimination efficiency is improved, and meanwhile, the cost is saved.
Further, a second embodiment of the noise cancellation method of the present invention is proposed.
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 equipment does not carry a 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 the fifth sound gain value;
r, if the current sound gain value is larger than the fifth sound gain value, subtracting the voice decibel value from the current sound gain value by the intelligent television system to obtain a sixth sound gain value, and detecting whether the sixth sound gain value is within a third preset decibel range set by the intelligent television system;
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 the terminal device without the touch screen, the intelligent television system detects whether the voice decibel is within a second preset decibel range set by the intelligent television system, if the voice decibel is detected to be within the second preset decibel range, the intelligent television system starts a voice gain extreme speed reduction adjustment mode, namely the intelligent television system acquires a voice gain value corresponding to the target terminal device, calculates a product of the voice gain value corresponding to the target terminal device and a second preset proportion set by the intelligent television system, acquires a corresponding fifth voice gain value, then determines a current voice gain value corresponding to the target terminal device, detects whether the current voice gain value is larger than the fifth voice gain value, if the current voice gain value is detected to be larger than the fifth voice gain value, the intelligent television system subtracts the voice decibel from the current voice gain value to acquire a corresponding sixth voice gain value, and then detects whether the sixth voice gain value is within a third preset decibel range set by the intelligent television system, and if the sixth voice gain value is detected to be within the third preset range, the intelligent television system determines the sixth voice gain value to be the target gain value corresponding to the target terminal device. If the sixth sound gain value is out of the third preset decibel range, multiplying the sixth sound gain value by a preset proportion, adjusting the sixth sound gain value to be within the third preset decibel range, and determining the adjusted sixth sound gain value as a target sound gain value corresponding to the target terminal equipment by the intelligent television system.
In this embodiment, if it is detected that the target terminal device does not 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 voice decibel, so as to improve the certainty of the target sound gain value.
