Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The first embodiment,
An embodiment of the present invention provides an information processing method applied to an electronic device, as shown in fig. 1, including:
step 101: acquiring voice information, and performing frequency conversion on the voice information to obtain sound wave information; the frequency range of the sound wave information is a frequency range which cannot be directly perceived by human ears;
step 102: and sending out sound wave information corresponding to the voice information, so that the target object can generate audio resonance according to the sound wave information to acquire the voice information in the frequency range which can be directly perceived by human ears.
The method provided in this embodiment may be applied to an electronic device, which is capable of performing audio output through at least one audio output unit.
The voice information acquisition mode can be that voice information is acquired through an audio acquisition unit of the electronic equipment, or that the voice information is selected from a plurality of voice information stored in the electronic equipment.
The frequency conversion is performed on the voice information to obtain sound wave information, and the method comprises the following steps:
performing time domain division on the voice information to obtain a first part of voice sub-information and a second part of voice sub-information;
converting the first part of voice sub-information into sound waves of a first frequency band; converting the second part of voice sub-information into sound waves of a second frequency band;
superposing the sound wave of the first frequency band and the sound wave of the second frequency band to obtain the sound wave information;
the first frequency band and the second frequency band are frequency ranges which cannot be directly perceived by human ears.
The method further comprises the following steps: acquiring voice information within a preset time length as currently acquired voice information through a voice acquisition unit;
correspondingly, time domain division is performed on the voice information to obtain a first part of voice sub-information and a second part of voice sub-information, and the method comprises the following steps:
and dividing the voice information into a first part of voice sub-information and a second part of voice sub-information based on the time length corresponding to the voice information.
It should be noted that the frequency conversion of the voice message may be such that the preset time duration may be a periodically repeated value, that is, the length of the preset time duration is equal to one acquisition period. The voice information in one collection period is converted, that is, when the current electronic device collects voice through an audio collection unit such as a microphone, the voice information in the period can be converted in frequency by taking the period as a unit. For example, referring to fig. 2, when a user sends a voice "hello", the user may perform time domain division according to a preset period, and if it is assumed that 50ms may be used as an acquisition period, that is, first 50ms of voice information is first used as a first segment of voice information; in the present embodiment, a mobile phone is taken as an example of a device for collecting voice, but any electronic device capable of collecting voice information is within the scope of the present embodiment.
Then, the 50ms first segment of voice information is divided again to obtain the first part of voice sub-information and the second part of voice sub-information, and the dividing mode can be divided according to the time length occupying half of each time length, and can also be divided according to the time lengths occupying different time lengths. If the voice sub-information is divided into different time lengths, the time length of the first part of voice sub-information is longer than that of the second part of voice sub-information, or the time length of the first part of voice sub-information is shorter than that of the second part of voice sub-information. In this embodiment, only two parts of voice sub-information can be obtained by dividing each section of voice information, and the duration is not limited nor exhaustive. For example, based on the processing in fig. 2, as shown in fig. 3, a first speech segment of 50ms may be divided into two first part speech sub-information 21 and second part speech sub-information 22 with the same duration.
Further, converting the first part of voice sub-information into sound waves of a first frequency band, and converting the second part of voice sub-information into sound waves of a second frequency band;
two frequency bands may be determined based on the hearing range of a person; specifically, the human auditory range, i.e., the frequency of vibration per second, is 20 to 20000 hz, and various sounds are heard in this range by the human ear. Above 20000 hertz (Hz) is called ultrasound, while below 20Hz is called infrasound (or subsonic), both of which are sounds inaudible to the human ear. Namely, the frequency range of the voice frequency range in which the voice information can be listened to by human ears is between 20Hz and 20kHz, so that the frequency conversion is carried out in the first step, the audible frequency in the voice information is subjected to ultrasonic and infrasonic conversion, so that two sound waves which cannot be listened by human ears can be generated by the voice, and the synthesizable sound wave decomposition is carried out through an algorithm. The first frequency band may be an ultrasonic frequency band, and the second frequency band may be a sub-acoustic frequency band. Still referring to fig. 3, it is assumed that the original two partial speech sub-messages 21, 22 are both in the frequency range between 20Hz and 20 kHz; after frequency conversion, a first frequency band acoustic wave 211 is obtained, which has a frequency band above 20000 hertz (Hz), and a second frequency band acoustic wave 221, i.e., infrasound (or infrasound) below 20 hertz (Hz).
Then, superposing the sound wave of the first frequency band and the sound wave of the second frequency band to obtain the sound wave information; the two frequency bands can be overlapped in a time domain in a manner of overlapping the sound waves of the two frequency bands, for example, the starting time point of the original sound wave of the first frequency band is t1, and the starting time point of the sound wave of the second frequency band is t 2; and then combining the sound waves of the two frequency ranges by adopting the same time point t0 to obtain the superposed sound wave information.
It can be understood that, the foregoing description has been given only by taking a part of the speech information as an example, and the speech information processing manner of other time domain parts is the same as that of the speech information processing method, and is not repeated here.
Or, the way of dividing the two parts of voice sub-information may be: dividing the voice information into at least one piece of sub-information based on the duration corresponding to the voice information; and extracting partial adjacent or non-adjacent sub information in the time domain from the at least one piece of sub information to be used as the first part of voice sub information, and extracting the rest part of adjacent or non-adjacent sub information in the time domain to be used as the second part of voice sub information.
For example, referring to fig. 4, the voice information is divided into a plurality of sub information from the time domain, for example, the 4 sub information shown in the figure are 41, 42, 43, 44 respectively; extracting adjacent or non-adjacent sub information from the 4 pieces of sub information as first part of voice sub information, wherein the two parts 41 and 42 can be extracted as the first part of sub information, or 41 and 43 can be extracted as the first part of voice sub information, or 41 and 44 can be extracted as the first part of voice sub information; then the rest part is used as the second part of the voice sub-information; in fig. 4, the sub information 41 and 43 are taken as the first part of sub information, and 42 and 44 are taken as the second part of sub information for example, and other division manners may exist, which are not exhaustive here.
In addition, the manner of converting the different pieces of speech sub information in the processing manner may be the same as the manner described above in this embodiment, and is not described again here.
Therefore, by adopting the scheme, when the voice information is acquired, frequency conversion can be carried out to obtain the sound wave information in the frequency range which can not be directly perceived by human ears, and then the sound wave information is sent out to enable a target object receiving the sound wave information to directly obtain the voice information through resonance of the sound wave information at the human ear side. Therefore, the frequency band conversion of the sound signals in the transmission can be carried out to enable the sound signals to be located outside the ear answering range, when the signals reach a receiver, the sound signals are located in the ear answering range through the cross superposition of sound waves, therefore, interactive information between two users is prevented from being known by other people, the privacy of the sound information is guaranteed, and the interactive privacy of the users is improved.

An embodiment of the present invention provides an information processing method applied to an electronic device, as shown in fig. 1, including:
step 101: acquiring voice information, and performing frequency conversion on the voice information to obtain sound wave information; the frequency range of the sound wave information is a frequency range which cannot be directly perceived by human ears;
step 102: and sending out sound wave information corresponding to the voice information, so that the target object can generate audio resonance according to the sound wave information to acquire the voice information in the frequency range which can be directly perceived by human ears.
The method provided in this embodiment may be applied to an electronic device, which is capable of performing audio output through at least one audio output unit.
The voice information acquisition mode can be that voice information is acquired through an audio acquisition unit of the electronic equipment, or that the voice information is selected from a plurality of voice information stored in the electronic equipment.
The frequency conversion is performed on the voice information to obtain sound wave information, and the method comprises the following steps:
performing time domain division on the voice information to obtain a first part of voice sub-information and a second part of voice sub-information;
converting the first part of voice sub-information into sound waves of a first frequency band; converting the second part of voice sub-information into sound waves of a second frequency band;
superposing the sound wave of the first frequency band and the sound wave of the second frequency band to obtain the sound wave information;
the first frequency band and the second frequency band are frequency ranges which cannot be directly perceived by human ears.
The method further comprises the following steps: acquiring voice information within a preset time length as currently acquired voice information through a voice acquisition unit;
correspondingly, time domain division is performed on the voice information to obtain a first part of voice sub-information and a second part of voice sub-information, and the method comprises the following steps:
and dividing the voice information into a first part of voice sub-information and a second part of voice sub-information based on the time length corresponding to the voice information.
It should be noted that the frequency conversion of the voice message may be such that the preset time duration may be a periodically repeated value, that is, the length of the preset time duration is equal to one acquisition period. The voice information in one collection period is converted, that is, when the current electronic device collects voice through an audio collection unit such as a microphone, the voice information in the period can be converted in frequency by taking the period as a unit.
Then, the 50ms first segment of voice information is divided again to obtain the first part of voice sub-information and the second part of voice sub-information, and the dividing mode can be divided according to the time length occupying half of each time length, and can also be divided according to the time lengths occupying different time lengths. If the voice sub-information is divided into different time lengths, the time length of the first part of voice sub-information is longer than that of the second part of voice sub-information, or the time length of the first part of voice sub-information is shorter than that of the second part of voice sub-information. In this embodiment, only two parts of voice sub-information can be obtained by dividing each section of voice information, and the duration is not limited nor exhaustive.
Further, converting the first part of voice sub-information into sound waves of a first frequency band, and converting the second part of voice sub-information into sound waves of a second frequency band;
two frequency bands may be determined based on the hearing range of a person; specifically, the human auditory range, i.e., the frequency of vibration per second, is 20 to 20000 hz, and various sounds are heard in this range by the human ear. Above 20000 hertz (Hz) is called ultrasound, while below 20Hz is called infrasound (or subsonic), both of which are sounds inaudible to the human ear. Namely, the frequency range of the voice frequency range in which the voice information can be listened to by human ears is between 20Hz and 20kHz, so that the frequency conversion is carried out in the first step, the audible frequency in the voice information is subjected to ultrasonic and infrasonic conversion, so that two sound waves which cannot be listened by human ears can be generated by the voice, and the synthesizable sound wave decomposition is carried out through an algorithm. The first frequency band may be an ultrasonic frequency band, and the second frequency band may be a sub-acoustic frequency band.
Then, superposing the sound wave of the first frequency band and the sound wave of the second frequency band to obtain the sound wave information; the two frequency bands can be overlapped in the time domain by overlapping the sound waves of the two frequency bands, so that the information of the sound waves after overlapping is obtained.
Or, the way of dividing the two parts of voice sub-information may be: dividing the voice information into at least one piece of sub-information based on the duration corresponding to the voice information; and extracting partial adjacent or non-adjacent sub information in the time domain from the at least one piece of sub information to be used as the first part of voice sub information, and extracting the rest part of adjacent or non-adjacent sub information in the time domain to be used as the second part of voice sub information.
In addition, the manner of converting the different pieces of speech sub information in the processing manner may be the same as the manner described above in this embodiment, and is not described again here.
The sending out the sound wave information corresponding to the voice information comprises:
acquiring the number N of audio output units; n is an integer; based on the number N of the audio output units, carrying out energy division on the sound wave information to obtain N pieces of sound wave sub information; and outputting the N pieces of sound wave sub information through the N audio output units.
Before the sending out the sound wave information corresponding to the voice information, the method further includes:
and controlling the pointing directions of the N audio output units so that the N audio output units all point to the target object.
The method for controlling the pointing directions of the N audio output units can be that the direction or the specific position (such as longitude and latitude) of a target user is firstly known, then the physical positions of the audio output units which can be controlled by the user are detected, and the N audio output units with the minimum distance from the target user are selected based on the physical positions of the audio output units;
then, based on the direction of the target user, the directions of the N audio output units are adjusted, for example, as shown in fig. 5, assuming that there are 4 audio output units (e.g., speakers) currently, and the position of the target user is a position closer to the audio output units 1 and 2, the two audio output units are selected as the final output units.
The energy division of the sound wave information may be performed by dividing the amplitude of the sound wave information, so that the sum of the sub-amplitudes of the divided sound wave sub-information can obtain the amplitude of the sound wave information, and the sub-amplitudes corresponding to each sound wave sub-information may be the same or different, which is not limited herein. And simultaneously sending the divided sound wave sub-information at the same time point in the time domain so that a target user can simultaneously acquire a plurality of sound wave sub-information from the N audio output units, and then combining the plurality of sound wave sub-information in the human ear to obtain final sound wave information.
In addition, based on the foregoing embodiment, it can be further described that another transmission manner may also exist in this embodiment, that is, the sound wave information obtained by conversion is sent to a mobile phone at a receiving end as communication voice information, so that when a user listens to the sound wave information through a speaker (audio output unit) of the mobile phone, the user knows to obtain specific voice information corresponding to the sound wave information based on vibration of an eardrum.
Therefore, by adopting the scheme, when the voice information is acquired, frequency conversion can be carried out to obtain the sound wave information in the frequency range which can not be directly perceived by human ears, and then the sound wave information is sent out to enable a target object receiving the sound wave information to directly obtain the voice information through resonance of the sound wave information at the human ear side. Therefore, the frequency band conversion of the sound signals in the transmission can be carried out to enable the sound signals to be located outside the ear answering range, when the signals reach a receiver, the sound signals are located in the ear answering range through the cross superposition of sound waves, therefore, interactive information between two users is prevented from being known by other people, the privacy of the sound information is guaranteed, and the interactive privacy of the users is improved.
Example III,
An embodiment of the present invention provides an electronic device, as shown in fig. 6, including:
the conversion unit 61 is configured to acquire voice information, perform frequency conversion on the voice information, and obtain sound wave information; the frequency range of the sound wave information is a frequency range which cannot be directly perceived by human ears;
and an output unit 62, configured to emit sound wave information corresponding to the voice information, so that the target object can generate audio resonance according to the sound wave information to acquire the voice information in a frequency range that can be directly perceived by human ears.
The method provided in this embodiment may be applied to an electronic device, which is capable of performing audio output through at least one audio output unit.
The voice information acquisition mode can be that voice information is acquired through an audio acquisition unit of the electronic equipment, or that the voice information is selected from a plurality of voice information stored in the electronic equipment.
The conversion unit 61 is configured to perform time domain division on the voice information to obtain a first part of voice sub-information and a second part of voice sub-information;
converting the first part of voice sub-information into sound waves of a first frequency band; converting the second part of voice sub-information into sound waves of a second frequency band;
superposing the sound wave of the first frequency band and the sound wave of the second frequency band to obtain the sound wave information;
the first frequency band and the second frequency band are frequency ranges which cannot be directly perceived by human ears.
The method further comprises the following steps: acquiring voice information within a preset time length as currently acquired voice information through a voice acquisition unit;
correspondingly, the converting unit 61 is configured to divide the voice information into a first part of voice sub-information and a second part of voice sub-information based on the duration corresponding to the voice information.
It should be noted that the frequency conversion of the voice message may be such that the preset time duration may be a periodically repeated value, that is, the length of the preset time duration is equal to one acquisition period. The voice information in one collection period is converted, that is, when the current electronic device collects voice through an audio collection unit such as a microphone, the voice information in the period can be converted in frequency by taking the period as a unit. For example, referring to fig. 2, when a user sends a voice "hello", the user may perform time domain division according to a preset period, and if it is assumed that 50ms may be used as an acquisition period, that is, first 50ms of voice information is first used as a first segment of voice information; in the present embodiment, a mobile phone is taken as an example of a device for collecting voice, but any electronic device capable of collecting voice information is within the scope of the present embodiment.
Then, the 50ms first segment of voice information is divided again to obtain the first part of voice sub-information and the second part of voice sub-information, and the dividing mode can be divided according to the time length occupying half of each time length, and can also be divided according to the time lengths occupying different time lengths. If the voice sub-information is divided into different time lengths, the time length of the first part of voice sub-information is longer than that of the second part of voice sub-information, or the time length of the first part of voice sub-information is shorter than that of the second part of voice sub-information. In this embodiment, only two parts of voice sub-information can be obtained by dividing each section of voice information, and the duration is not limited nor exhaustive. For example, based on the processing in fig. 2, as shown in fig. 3, a first speech segment of 50ms may be divided into two first part speech sub-information 21 and second part speech sub-information 22 with the same duration.
Further, converting the first part of voice sub-information into sound waves of a first frequency band, and converting the second part of voice sub-information into sound waves of a second frequency band;
two frequency bands may be determined based on the hearing range of a person; specifically, the human auditory range, i.e., the frequency of vibration per second, is 20 to 20000 hz, and various sounds are heard in this range by the human ear. Above 20000 hertz (Hz) is called ultrasound, while below 20Hz is called infrasound (or subsonic), both of which are sounds inaudible to the human ear. Namely, the frequency range of the voice frequency range in which the voice information can be listened to by human ears is between 20Hz and 20kHz, so that the frequency conversion is carried out in the first step, the audible frequency in the voice information is subjected to ultrasonic and infrasonic conversion, so that two sound waves which cannot be listened by human ears can be generated by the voice, and the synthesizable sound wave decomposition is carried out through an algorithm. The first frequency band may be an ultrasonic frequency band, and the second frequency band may be a sub-acoustic frequency band. Still referring to fig. 3, it is assumed that the original two partial speech sub-messages 21, 22 are both in the frequency range between 20Hz and 20 kHz; after frequency conversion, a first frequency band acoustic wave 211 is obtained, which has a frequency band above 20000 hertz (Hz), and a second frequency band acoustic wave 221, i.e., infrasound (or infrasound) below 20 hertz (Hz).
Then, superposing the sound wave of the first frequency band and the sound wave of the second frequency band to obtain the sound wave information; the two frequency bands can be overlapped in a time domain in a manner of overlapping the sound waves of the two frequency bands, for example, the starting time point of the original sound wave of the first frequency band is t1, and the starting time point of the sound wave of the second frequency band is t 2; and then combining the sound waves of the two frequency ranges by adopting the same time point t0 to obtain the superposed sound wave information.
It can be understood that, the foregoing description has been given only by taking a part of the speech information as an example, and the speech information processing manner of other time domain parts is the same as that of the speech information processing method, and is not repeated here.
Or, the converting unit 61 is configured to divide the voice information into at least one piece of sub information based on a duration corresponding to the voice information; and extracting partial adjacent or non-adjacent sub information in the time domain from the at least one piece of sub information to be used as the first part of voice sub information, and extracting the rest part of adjacent or non-adjacent sub information in the time domain to be used as the second part of voice sub information.
For example, referring to fig. 4, the voice information is divided into a plurality of sub information from the time domain, for example, the 4 sub information shown in the figure are 41, 42, 43, 44 respectively; extracting adjacent or non-adjacent sub information from the 4 pieces of sub information as first part of voice sub information, wherein the two parts 41 and 42 can be extracted as the first part of sub information, or 41 and 43 can be extracted as the first part of voice sub information, or 41 and 44 can be extracted as the first part of voice sub information; then the rest part is used as the second part of the voice sub-information; in fig. 4, the sub information 41 and 43 are taken as the first part of sub information, and 42 and 44 are taken as the second part of sub information for example, and other division manners may exist, which are not exhaustive here.
In addition, the manner of converting the different pieces of speech sub information in the processing manner may be the same as the manner described above in this embodiment, and is not described again here.
Therefore, by adopting the scheme, when the voice information is acquired, frequency conversion can be carried out to obtain the sound wave information in the frequency range which can not be directly perceived by human ears, and then the sound wave information is sent out to enable a target object receiving the sound wave information to directly obtain the voice information through resonance of the sound wave information at the human ear side. Therefore, the frequency band conversion of the sound signals in the transmission can be carried out to enable the sound signals to be located outside the ear answering range, when the signals reach a receiver, the sound signals are located in the ear answering range through the cross superposition of sound waves, therefore, interactive information between two users is prevented from being known by other people, the privacy of the sound information is guaranteed, and the interactive privacy of the users is improved.
Example four,
An embodiment of the present invention provides an electronic device, which has a structure similar to that of the foregoing embodiment, and the electronic device provided in this embodiment is a device capable of outputting audio through at least one audio output unit.
The voice information acquisition mode can be that voice information is acquired through an audio acquisition unit of the electronic equipment, or that the voice information is selected from a plurality of voice information stored in the electronic equipment.
The conversion unit 61 is configured to perform time domain division on the voice information to obtain a first part of voice sub-information and a second part of voice sub-information;
converting the first part of voice sub-information into sound waves of a first frequency band; converting the second part of voice sub-information into sound waves of a second frequency band;
superposing the sound wave of the first frequency band and the sound wave of the second frequency band to obtain the sound wave information;
the first frequency band and the second frequency band are frequency ranges which cannot be directly perceived by human ears.
The method further comprises the following steps: acquiring voice information within a preset time length as currently acquired voice information through a voice acquisition unit;
correspondingly, the converting unit 61 is configured to divide the voice information into a first part of voice sub-information and a second part of voice sub-information based on the duration corresponding to the voice information.
It should be noted that the frequency conversion of the voice message may be such that the preset time duration may be a periodically repeated value, that is, the length of the preset time duration is equal to one acquisition period. The voice information in one collection period is converted, that is, when the current electronic device collects voice through an audio collection unit such as a microphone, the voice information in the period can be converted in frequency by taking the period as a unit.
Then, the 50ms first segment of voice information is divided again to obtain the first part of voice sub-information and the second part of voice sub-information, and the dividing mode can be divided according to the time length occupying half of each time length, and can also be divided according to the time lengths occupying different time lengths. If the voice sub-information is divided into different time lengths, the time length of the first part of voice sub-information is longer than that of the second part of voice sub-information, or the time length of the first part of voice sub-information is shorter than that of the second part of voice sub-information. In this embodiment, only two parts of voice sub-information can be obtained by dividing each section of voice information, and the duration is not limited nor exhaustive.
Further, converting the first part of voice sub-information into sound waves of a first frequency band, and converting the second part of voice sub-information into sound waves of a second frequency band;
two frequency bands may be determined based on the hearing range of a person; specifically, the human auditory range, i.e., the frequency of vibration per second, is 20 to 20000 hz, and various sounds are heard in this range by the human ear. Above 20000 hertz (Hz) is called ultrasound, while below 20Hz is called infrasound (or subsonic), both of which are sounds inaudible to the human ear. Namely, the frequency range of the voice frequency range in which the voice information can be listened to by human ears is between 20Hz and 20kHz, so that the frequency conversion is carried out in the first step, the audible frequency in the voice information is subjected to ultrasonic and infrasonic conversion, so that two sound waves which cannot be listened by human ears can be generated by the voice, and the synthesizable sound wave decomposition is carried out through an algorithm. The first frequency band may be an ultrasonic frequency band, and the second frequency band may be a sub-acoustic frequency band.
Then, superposing the sound wave of the first frequency band and the sound wave of the second frequency band to obtain the sound wave information; the two frequency bands can be overlapped in the time domain by overlapping the sound waves of the two frequency bands, so that the information of the sound waves after overlapping is obtained.
Or, the way of dividing the two parts of voice sub-information may be: dividing the voice information into at least one piece of sub-information based on the duration corresponding to the voice information; and extracting partial adjacent or non-adjacent sub information in the time domain from the at least one piece of sub information to be used as the first part of voice sub information, and extracting the rest part of adjacent or non-adjacent sub information in the time domain to be used as the second part of voice sub information.
In addition, the manner of converting the different pieces of speech sub information in the processing manner may be the same as the manner described above in this embodiment, and is not described again here.
The output unit is used for acquiring the number N of the audio output units; n is an integer; based on the number N of the audio output units, carrying out energy division on the sound wave information to obtain N pieces of sound wave sub information; and outputting the N pieces of sound wave sub information through the N audio output units.
The output unit is used for controlling the pointing directions of the N audio output units, so that the N audio output units all point to the target object.
The method for controlling the pointing directions of the N audio output units can be that the direction or the specific position (such as longitude and latitude) of a target user is firstly known, then the physical positions of the audio output units which can be controlled by the user are detected, and the N audio output units with the minimum distance from the target user are selected based on the physical positions of the audio output units;
then, based on the direction of the target user, the directions of the N audio output units are adjusted, for example, as shown in fig. 5, assuming that there are 4 audio output units (e.g., speakers) currently, and the position of the target user is a position closer to the audio output units 1 and 2, the two audio output units are selected as the final output units.
The energy division of the sound wave information may be performed by dividing the amplitude of the sound wave information, so that the sum of the sub-amplitudes of the divided sound wave sub-information can obtain the amplitude of the sound wave information, and the sub-amplitudes corresponding to each sound wave sub-information may be the same or different, which is not limited herein. And simultaneously sending the divided sound wave sub-information at the same time point in the time domain so that a target user can simultaneously acquire a plurality of sound wave sub-information from the N audio output units, and then combining the plurality of sound wave sub-information in the human ear to obtain final sound wave information.
In addition, based on the foregoing embodiment, it can be further described that another transmission manner may also exist in this embodiment, that is, the sound wave information obtained by conversion is sent to a mobile phone at a receiving end as communication voice information, so that when a user listens to the sound wave information through a speaker (audio output unit) of the mobile phone, the user knows to obtain specific voice information corresponding to the sound wave information based on vibration of an eardrum.
Therefore, by adopting the scheme, when the voice information is acquired, frequency conversion can be carried out to obtain the sound wave information in the frequency range which can not be directly perceived by human ears, and then the sound wave information is sent out to enable a target object receiving the sound wave information to directly obtain the voice information through resonance of the sound wave information at the human ear side. Therefore, the frequency band conversion of the sound signals in the transmission can be carried out to enable the sound signals to be located outside the ear answering range, when the signals reach a receiver, the sound signals are located in the ear answering range through the cross superposition of sound waves, therefore, interactive information between two users is prevented from being known by other people, the privacy of the sound information is guaranteed, and the interactive privacy of the users is improved.
