Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The volume control method provided by the embodiment of the application is used for adjusting the volume of the sound playing device. The processing flow of the method is realized in a processor, and the processor can be a software processing device installed in the sound playing device or other software processing devices capable of communicating with the sound playing device. The sound playing device may be any one of a stand-alone audio device, a television sound playing component, and other devices for playing sound. The scope of protection of the present application is not limited to the specific type of sound playing device.
In one embodiment, as shown in fig. 1, the volume control method is implemented by the following specific steps:
In this embodiment, the target object refers to an object for adjusting the volume of the sound playing device, and the specific type of the target object may be selected according to actual conditions and needs, for example, the target object may be a human body, or may also be an intelligent device such as a robot, an intelligent bracelet, and an intelligent mobile phone. The scope of protection of the present application is not limited to a particular type of target object.
In this embodiment, when the current distance value between the target object and the sound playing device is obtained, a required technical means may be selected to complete obtaining the current distance value according to conditions such as an environmental requirement, a technical requirement, or a cost requirement. For example, any one of infrared technology, ultrasonic technology, millimeter wave technology, image processing technology, and other technical means may be employed in acquiring the current distance value. The scope of protection of the present application is not limited by the technical means employed to obtain the current distance value.
And 102, acquiring a first volume value corresponding to the current distance value according to the current distance value.
In this embodiment, the correspondence between the distance value and the volume value may be preset and stored. Specifically, the corresponding relationship may be set in a specific implementation form according to actual conditions and needs, and the scope of protection of the present application is not limited by the specific implementation form of the corresponding relationship. Preferably, the correspondence between the distance value and the volume value may be set to be a positive correlation, that is, the set volume value is larger as the distance between the target object and the sound playing device is larger, for example, the volume value is 20 decibels (dB) when the distance between the target object and the sound playing device is 1 meter, and the volume value is 40dB when the distance between the target object and the sound playing device is 2 meters.
When the first volume value is determined, the sound playing device automatically adjusts the current volume to the first volume value to play music. Since the first volume value is determined according to the current distance value between the target object and the sound playing device, the adjusted current volume of the sound playing device provides a better sound experience for the user.
In one embodiment, the technical means used for obtaining the current distance value is the millimeter wave technology. Specifically, a current distance value between the target object and the sound playing device is obtained, and the implementation process is as follows: acquiring a millimeter wave signal, wherein the millimeter wave signal is used for measuring the distance between a target object and a sound playing device; and analyzing the millimeter wave signal to obtain the current distance value between the target object and the sound playing device.
The millimeter wave refers to an electromagnetic wave with the wavelength of 1-10 mm, and is located in the overlapping wavelength range of microwave and far infrared wave, so that the millimeter wave has the characteristics of two wave spectrums. After the millimeter wave transmitting device transmits millimeter waves to a space, the target existing in the space can reflect an echo, and the millimeter wave receiving device can receive the echo to perform other processing.
The millimeter wave signal in the present embodiment refers to an echo reflected by a target. When the target object returns to the millimeter wave signal, the millimeter wave signal includes the radial distance and the radial velocity of the target object. Based on the above, the distance between the target object and the sound playing device can be measured by the millimeter wave signal.
In this embodiment, the millimeter wave receiving device may be installed in the sound playing device, and the millimeter wave receiving device on one side of the sound playing device receives the millimeter wave signal, so that the current distance value between the target object and the sound playing device may be obtained more accurately. The millimeter wave transmitting device and the millimeter wave receiving device can be installed in the sound playing device at the same time, and can also be installed at other positions as long as the method and the process of the application can be realized.
In one embodiment, the millimeter wave signal includes velocity information of the target object. Then, the millimeter wave signal is analyzed to obtain the current distance value between the target object and the sound playing device, and the specific implementation process is as follows: after a target object is identified from the millimeter wave signal, detecting the current speed of the target object; when the current speed is determined to be zero, the millimeter wave signal is analyzed, and a current distance value between the target object and the sound playing device is obtained.
In this embodiment, by extracting the current speed of the target object from the millimeter wave signal, when the current speed of the target object is not zero, it indicates that the target object is moving, and when the current speed of the target object is zero, it indicates that the target object is stationary at a position and does not move any more. When the target object does not move any more, the current distance value of the target object is extracted from the millimeter wave signal to adjust the current volume of the sound playing device. Through the process, the situation that when the target object moves, the current volume of the sound playing device changes continuously, and then resource waste and poor sound playing effect are caused can be avoided.
In one embodiment, the target object is at least one human individual, for example, three individuals, individual 1, individual 2, and individual 3, in a family space. The sound playing device needs to adjust the current volume according to at least one individual human body. Specifically, when the millimeter wave signal is analyzed to obtain the current distance value between the target object and the sound playing device, the millimeter wave signal is analyzed to obtain the current distance value of each individual human body. According to the current distance value, obtaining a first volume value corresponding to the current distance value, and the specific process is as follows: respectively determining the preset distance range of each individual human body according to the current distance value of each individual human body; determining a comprehensive distance value according to a preset distance range in which each individual human body is located; and acquiring a first volume value corresponding to the comprehensive distance value.
In this embodiment, when the target object is a human body, and when the target object is a human body, the millimeter wave signal includes not only the radial distance and the radial velocity of the human body, but also micro-motion information of each part of the human body, and the micro-motion information may cause a doppler effect. And the micro-doppler characteristics of each individual human body due to the micro-motion information are different. By analyzing the millimeter wave signals, different human bodies can be determined, and tracking of each human body can be completed. That is to say, each individual human body can be identified through the millimeter wave signal, and then the current distance value of each individual human body is analyzed.
In this embodiment, the preset distance range is a range in which the sound playing device is used as a circle center and the preset distance value is used as a radius. The preset distance range is preset according to actual conditions and needs. The preset distance ranges are in stepped presentation. For example, as shown in fig. 2, three preset distance ranges are set with the sound playing device as the center, and the first preset distance range takes 0 meter to 1 meter (including 1 meter) from the sound playing device as a preset distance value, that is, the first concentric circle range outside the sound playing device in fig. 2 is the first preset distance range. The second predetermined distance range is a predetermined distance value of 1 meter to 3 meters (including 3 meters) from the sound playing apparatus, that is, the range outside the first concentric circle and inside the second concentric circle outside the sound playing apparatus in fig. 2 is the second predetermined distance range. The third predetermined distance range is a predetermined distance value of 3 meters to 4 meters (including 4 meters) from the sound playing device, that is, the range outside the second concentric circle and inside the third concentric circle outside the sound playing device in fig. 2 is a third predetermined distance range. And determining a comprehensive distance value according to the preset distance range of each individual human body, and then determining a first volume value according to the comprehensive distance value.
In a specific embodiment, when the comprehensive distance value is determined according to the preset distance range in which each individual human body is located, the maximum preset distance range and the minimum preset distance range are determined in the preset distance range in which each individual human body is located; carrying out average calculation on the maximum value in the maximum preset distance range and the maximum value in the minimum preset distance range to obtain an average distance value; and taking the average distance value as a comprehensive distance value.
For example, when there are three human individuals, namely, the individual 1, the individual 2 and the individual 3, the preset distance range of the individual 1 is 0 to 1 meter, the preset distance range of the individual 2 is 1 to 3 meters, the preset distance range of the individual 3 is 3 to 4 meters, the maximum preset distance range is 3 to 4 meters, and the minimum preset distance range is 0 to 1 meter. Then, the average calculation is carried out on the 4 meters and the 1 meter, and the obtained average distance value is 2.5 meters, so that the obtained average distance value is a comprehensive distance value.
For another example, when there are three human individuals, namely, the individual 1, the individual 2 and the individual 3, the preset distance range of the individual 1 and the individual 2 is 1 meter to 3 meters, and the preset distance range of the individual 3 is 3 meters to 4 meters, then the maximum preset distance range is 3 meters to 4 meters, and the minimum preset distance range is 1 meter to 3 meters. Then, the average calculation is carried out on 4 meters and 3 meters, and the obtained average distance value is 3.5 meters, and 3.5 meters are comprehensive distance values.
In another specific embodiment, when determining the comprehensive distance value according to the preset distance range in which each individual human body is located, the specific rule may also adopt other specific forms, for example, after determining the maximum preset distance range and the minimum preset distance range, average calculation is performed on the minimum value in the maximum preset distance range and the minimum value in the minimum preset distance range to obtain the comprehensive distance value; or after the maximum preset distance range and the minimum preset distance range are determined, average calculation is carried out on the preset intermediate value in the maximum preset distance range and the preset intermediate value in the minimum preset distance range to obtain a comprehensive distance value. Or directly carrying out average calculation on the current distance value of each human body individual, and determining the first volume value by taking the average distance value as a comprehensive distance value. The process of determining the first volume value through the current distance value of at least one human individual can be set according to the actual situation and the requirement.
In the above embodiment, when the millimeter wave signal includes information of at least one human body individual, the current distance value of each human body individual is extracted, and then the current volume of the sound playing device is adjusted according to the current distance value of each human body individual. Therefore, the volume adjustment of the sound playing device is specific to each individual human body, and is not specific to one individual human body when two or more individual human bodies exist, so that the situation that a person far away from the sound playing device cannot hear the sound or a person near the sound playing device hears too much sound is avoided, and better sound experience is provided for a user.
In one embodiment, when the human body is at least one human body individual, the speed information of each human body individual is extracted from the millimeter wave signal, specifically, the millimeter wave signal is analyzed, and the current distance value of each human body individual is obtained respectively, and the implementation process is as follows: after each human individual is identified from the millimeter wave signals, detecting the current speed of each human individual; and when the current speed of each human body individual is determined to be zero at the same time, analyzing the millimeter wave signals and respectively obtaining the current distance value of each human body individual.
In this embodiment, the current speed of each individual human body is extracted from the millimeter wave signal, and when the current speed of each individual human body is zero at the same time, that is, when each individual human body does not move, the current distance value of each individual human body is obtained, so that the situation that the volume is continuously adjusted by the sound playing device in the process that any individual human body moves is avoided.
In one embodiment, there are various disturbances in the environment where the human body is located, such as noise in the environment, or attenuation of sound by obstacles. In order to eliminate the influence of interference, an interference filtering weight is preset. Specifically, according to the current distance value, a first volume value corresponding to the current distance value is obtained, and the implementation process is as follows: acquiring a preset interference filtering weight, wherein the interference filtering weight is used for eliminating the interference of the environment where the sound playing device is located; weighting the current distance value through the interference filtering weight value; and acquiring a first volume value corresponding to the current distance value after weighting processing.
Specifically, the weighting process is as follows:
and the current distance value after weighting processing is equal to the current distance value multiplied by the interference filtering weight value.
For example, when the obtained current distance value is 1 meter, the millimeter wave signal passes through a solid wall obstacle, and the interference filtering weight value corresponding to the preset solid wall obstacle is 1.1, the current distance value after weighting processing is 1.1 meter.
In this embodiment, when there are multiple types of interference, i.e., interference 1, interference 2, …, and interference N, where N is an integer greater than 1, the corresponding interference filtering weight 1, interference filtering weight 2, …, and interference filtering weight N are preset respectively, and the weighting process under multiple types of interference is as follows:
the current distance value after weighting processing under multiple kinds of interference is equal to the current distance value × interference filtering weight 1 × interference filtering weight 2 × … × interference filtering weight N.
In this embodiment, the interference of the environment where the sound playing device is located is eliminated by presetting the interference filtering weight. The interference filtering weight value can be set to a specific numerical value according to experiments or practical experience, and the protection range of the application is not limited by the setting rule and the setting numerical value of the interference filtering weight value.
In one embodiment, when the target object is a human body, the human body may control whether the sound playing device can adjust the volume by the distance by making a gesture. Specifically, after the millimeter wave signal is acquired, the millimeter wave signal is analyzed, and when first gesture information is identified from the millimeter wave signal before a current distance value between the target object and the sound playing device is acquired, a volume maintaining instruction is acquired, wherein the volume maintaining instruction is used for indicating that the current volume of the sound playing device is unchanged; and controlling the current volume of the sound playing device to be unchanged according to the volume maintaining instruction.
When the current volume of the sound playing device is controlled to be unchanged according to the volume maintaining instruction, and when second gesture information is identified from the millimeter wave signals, a volume regulating instruction is obtained, wherein the volume regulating instruction is used for indicating the sound playing device to regulate and control the current volume; and controlling the sound playing device to regulate and control the current volume according to the current distance value of the human body in the millimeter wave signal according to the volume regulation and control instruction.
In this embodiment, the user may control whether the sound playing device starts the function of adjusting the current volume according to the current distance value of the human body through the gesture. When the user does not need to adjust the current volume through the current distance value of the human body, first gesture information is made, and then after the first gesture information is identified through the millimeter wave signals, a volume maintaining instruction is obtained to indicate that the current volume is unchanged. And when the user needs to adjust the current volume according to the current distance value of the human body, making second gesture information, identifying the second gesture information through the millimeter wave signal, and acquiring a volume adjusting and controlling instruction to instruct the sound playing device to adjust and control the current volume.
Specifically, the first gesture information may be any one of palm opening, palm holding, hand upward movement, hand downward movement, and other types of gesture information, and similarly, the second gesture information may be any one of palm opening, palm holding, hand upward movement, hand downward movement, and other types of gesture information. Meanwhile, the first gesture information and the second gesture information are different.
In this embodiment, when the target object includes at least one human individual, and when the first gesture information of any one human individual is recognized, the distance between each human individual and the sound playing device is changed, and the volume of the sound playing device is kept unchanged. And when the second gesture information of any one human body individual is identified, the sound playing device controls the current volume of the sound playing device according to the current distance value between each human body individual and the sound playing device.
In this embodiment, when the user does not want the volume of the sound playing device to change, the sound playing device can be controlled to be unchanged through the gesture information, so that the diversification of volume control is increased, the practicability of the volume control method is improved, and the experience of the user is further improved.
In one embodiment, the sound playing device is a floating sound box. The suspension sound box comprises a base and a sound box, wherein the sound box is suspended above the base.
In a specific embodiment, the millimeter wave transmitter is installed on the base, the millimeter wave receiver is also installed on the base, and the processor installed in the base processes the millimeter wave signal and transmits the signal for controlling the volume to the sound box to play the sound with the first volume value.
In a specific embodiment, the millimeter wave generating device is mounted on the base, and the millimeter wave receiving device is mounted on the sound box. After the sound box receives the millimeter wave signals, the processor in the sound box directly processes the millimeter wave signals, and the process of playing sound with the first volume value is achieved.
In a specific embodiment, the base and the sound box may be simultaneously installed with millimeter wave integrated chips, for example, an integrated chip with model ST60 is used, and the millimeter wave integrated chip is an integrated millimeter wave transceiver, and is capable of transmitting millimeter wave signals and receiving millimeter wave signals.
In this embodiment, the millimeter wave integrated chip receives the millimeter wave signal, and the process of playing the sound with the first volume value is implemented.
In this embodiment, when the millimeter wave chip is the ST60 chip, the process of data communication can be realized by this ST60 chip. The ST60 chips communicate with each other in the 60GHz frequency band by the millimeter wave technology.
At present, the sound quality of the suspended sound box is uneven, and one reason is that the sound quality is different due to audio and video data transmission between the base and the sound box. The mode that data transmission between present base and the audio amplifier adopted is mostly bluetooth, wifi transmission. The wireless transmission mode can influence the auditory effect to a certain extent, and the reason is that when the data volume is overlarge or the number of devices using the network at the same time is large, the problem of network signal congestion is caused, so that audio and video transmission and analysis of sound are realized. The millimeter wave technology has the advantages of being wide in frequency spectrum, high in reliability, good in directivity and the like, and signal congestion cannot occur. And the distance between the base of the suspension sound and the sound is short, and the millimeter wave technology is particularly suitable for short-distance data transmission.
As shown in fig. 3, the floating audio device 30 includes a base 301 and a sound box 302, and other terminal devices, for example, a mobile phone terminal 303, a television terminal 304, or a projection terminal 305, can implement data transmission with the floating audio device 30, mainly implement transmission with the base 301, and implement playing of required sound.
In one implementation form, the transmission between the mobile phone terminal 303, the television terminal 304, or the projection terminal 305 and the floating audio 30 may respectively adopt a data conversion interface form to transmit audio and video data to be played to the base 301, and then the base 301 transmits the audio and video data to the sound box 302 through the ST60 chip by adopting a millimeter wave technology, so as to play sound information contained in the audio and video data.
In another implementation form, other terminal devices such as the mobile phone terminal 303, the television terminal 304, or the projection terminal 305 are respectively provided with an ST60 chip, and each terminal device directly communicates with the base 301 through the ST60 chip. The audio and video data is directly transmitted in a 60GHz frequency band through a millimeter wave technology. That is, it is not necessary to establish a communication connection between each terminal device and the floating sound 30, but data transmission is directly performed by the millimeter wave technology. The millimeter wave technology has the advantages of wide spectrum, high reliability, good directivity and the like, improves the transmission precision of audio and video data, ensures the quality of played sound, and avoids the problem that audio and video effects are affected by sound blockage, noise and the like caused when terminal equipment transmits data in the forms of Bluetooth, wifi transmission and the like.
Meanwhile, data transmission is carried out by adopting a millimeter wave technology, and data transmission can be realized without a network distribution between the terminal equipment of the mobile phone terminal and the suspension sound equipment. The operation steps of playing the sound are further simplified, and the convenience in the process of playing the sound is improved.
According to the volume control method, the current distance value between the target object and the sound playing device is obtained, then the first volume value is determined according to the current distance value, and finally the current volume of the sound playing device is adjusted to the first volume value. The method adjusts the current volume of the sound playing device according to the current distance value between the target object and the sound playing device. That is to say, in the process of volume adjustment, the device such as a key or a controller is not needed, so that the complexity of the volume adjustment process is greatly reduced, and the convenience of volume adjustment is improved.
When the target object is a human body, the method adjusts the current volume of the sound playing device according to the current distance value between the human body and the sound playing device. That is to say, in the process of volume adjustment, the user does not need to approach the sound playing device and the user does not need to find the remote controller, so that the experience of the user is improved.
