Description

Audio playing method and system, mobile terminal and WiFi earphone

Technical Field

The present disclosure relates to the field of mobile communications technologies, and in particular, to an audio playing method and system, a mobile terminal, and a WiFi headset.

Background

At present, mobile terminals are becoming more popular and are moving toward more intelligent, more integrated and more powerful functions. While most mobile terminals are used without audio playback. The performance of the mobile terminal in the audio playing process directly influences the user experience of the mobile terminal, and further influences the position of the mobile terminal in the market.

In the audio playing process, the existing mobile terminal mainly has two modes of playing through a loudspeaker and playing through an earphone. When playing through a loudspeaker, a plurality of users can acquire the audio at the same time, but the audio playing quality is easily affected by noise in the environment, the user privacy is poor, other people in the environment are easily affected, and inconvenience is caused to the lives of other people. When playing through the earphone, the influence of noise in the environment on the audio playing quality can be avoided, the privacy of a user is protected, and the life of other people is not influenced. However, when the existing mobile terminal is connected with the earphone, whether the mobile terminal is connected in a wired mode through the earphone jack or in a wireless mode through Bluetooth, the mobile terminal corresponds to one wired earphone or one Bluetooth earphone, only one person can receive audio played by the mobile terminal, and the requirement that multiple persons listen to the audio at the same time cannot be met.

In addition, because the length of the output line of the wired earphone is limited, the user can only move in a certain range near the mobile terminal, and the moving range of the user in the process of listening to the audio is greatly limited. The transmission distance of bluetooth in the open environment is only about ten meters, and the range of motion of the user is also limited when the bluetooth headset receives the audio played by the mobile terminal. Moreover, the transmission rate of bluetooth is limited, and efficiency is lower, stability is relatively poor when carrying out audio transmission through bluetooth, leads to bluetooth headset broadcast's audio quality not high.

Therefore, how to improve the quality of audio played by a mobile terminal and to enable audio played by a plurality of headphones in a mobile terminal to be played simultaneously is one of the problems to be solved by those skilled in the art.

Because the current position parameter of the WiFi headset corresponds to the head position of the user using the WiFi headset, when the head position of the user changes, the current position parameter of the WiFi headset also changes. When the head position of the user changes, the current position parameters of the audio file and the WiFi earphone are subjected to algorithm fusion and then played through the WiFi earphone, so that the sound source position of the virtual scene simulated by the audio file in the brain of the user is fixed, the hearing mode of the user in a real boundary is met, the hearing feeling of the user is more comfortable, and the playing quality of the audio file is improved.

Further, the mobile terminal is connected with more than two WiFi headsets under the same WiFi network, so that the audio files of the mobile terminal can be played in a plurality of WiFi headsets at the same time. Compared with the mode that the audio file is played through the loudspeaker so that multiple users can listen to the same audio file at the same time, the audio playing scheme can effectively protect the privacy of the users and avoid affecting the life of other people in the environment.

Furthermore, the algorithm fusion is performed on the current position parameters of the WiFi earphone and the audio file, and the formation of the audio file after the algorithm fusion specifically comprises the following steps: calibrating a position sensor in the WiFi earphone, and determining reference playing volume and reference position parameters of the WiFi earphone; then, calculating the position deviation parameter of the WiFi earphone according to the reference position parameter and the current position parameter of the WiFi earphone; then, calculating the left volume offset and the right volume offset of the WiFi earphone according to the position offset parameter of the WiFi earphone; and finally, calibrating the audio file according to the reference play volume, the left volume offset and the right volume offset of the WiFi earphone to form an audio file after algorithm fusion. Therefore, the volume of the left earphone and the right earphone in the WiFi earphone is adjusted according to the head position change of the user, and the sound source position of the simulated scene formed in the brain of the user is adjusted. For audio file playing matched with image watching, the user can accurately judge the sound source position in the virtual scene, and the sound source position is consistent with the real scene of the corresponding change of the sound source relative to the position of the user when the position of the user is changed, so that the listening experience of the user is more real, the accuracy of audio file scene simulation is improved, and the listening experience of the audio file of the user is better.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a mobile terminal of the present application, and as shown in the drawing, the mobile terminal 10 includes a first WiFi module 11, an information receiving module 12, a first audio file processing module 13, and an audio transmitting module 14. The first WiFi module 11 is used for connecting with a WiFi headset under the same WiFi network. The information receiving module 12 is configured to receive, via the first WiFi module 11, a current position parameter of the WiFi headset. The first audio file processing module 13 is configured to algorithmically fuse the current position parameter of the WiFi headset with an audio file. The audio sending module 14 is configured to send the audio file subjected to the algorithm fusion to the connected WiFi headset through the first WiFi module 11, so that the WiFi headset receives the audio file and plays the audio file.

The audio files in the mobile terminal 10 may be independent audio information (e.g., music, recordings, etc.), or may be audio information combined with other information (e.g., audio information in a movie multimedia file), and the audio information in the audio file may be in a format in which the mobile terminal stores audio, such as MP3 format, WMA format, WAV format, ASF format, AAC format, VQF format, FLAC format, APE format, OGG format, etc.

In this embodiment, the first WiFi module 11 is a wireless network card supporting a wireless communication standard protocol, and works in the last two layers of OSI: physical layer and data link layer. The physical layer defines the electrical and optical signals, line states, clock bases, data encoding and circuitry, etc. required for data transmission and reception and provides a standard interface to the data link layer devices. The chip of the physical layer is called PHY. The data link layer provides the functions of addressing mechanism, data frame construction, data error checking, transmission control, data interface providing standard data interface standard for network layer, etc. The chips of the data link layer in ethernet are called MAC controllers. The PHY and the MAC controller of many network cards are connected together, and the relation between the two parts is that the PCI bus is connected with the MAC bus, the MAC bus is connected with the PHY, and the PHY is connected with the network.

In this embodiment, the first audio file processing module 13 may be a Central Processing Unit (CPU). Which may communicate with the first WiFi module 11 via one or more PCI (Peripheral Component Interconnect, peripheral component interconnect standard) buses. It should be understood that the mobile terminal of fig. 1 is merely an example of a mobile terminal and that the components of the mobile terminal may have more or fewer components than shown or a different configuration of components. The various components shown in fig. 1 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

In this embodiment, the current position parameter of the WiFi headset is obtained by sensing a position sensor disposed in the WiFi headset. Specifically, the position sensor is a gyroscope, for example, the balance sensor is a three-axis gyroscope. The three-axis gyroscope is a core sensitive device of an inertial navigation system, and the biggest role of the three-axis gyroscope is to measure angular velocity so as to judge the motion state of an object, so the three-axis gyroscope is also called a motion sensor, and can be used for rotation detection requiring high resolution and quick response. When a user performs small-range activities, the gyroscope can accurately position the WiFi earphone with lower cost, and the acquired current position parameters of the WiFi earphone are accurate.

In other embodiments, the position sensor may also be a gyroscope and an acceleration sensor. The acceleration sensor is one of basic measuring elements of an inertial navigation and inertial guidance system, is a sensor for measuring acceleration, generates gravity components on three coordinate axes due to the action of gravity when an object is in a static state, quantifies the gravity components and utilizes a trigonometric function to calculate the inclination angles of the object relative to the three coordinate axes. From the application direction of the gyroscope, the gyroscope can measure the angular velocity of motion along one axis or a plurality of axes, can form advantage complementation with the acceleration sensor, and if the two sensors of the acceleration sensor and the gyroscope are used in combination, the complete motion of the three-dimensional space of the WiFi headset can be tracked and captured better, so that the current position parameter of the WiFi headset can be determined accurately. The current position parameters of the WiFi headset can be accurately determined even if the user performs a large range of activities.

In a specific implementation scene that a user listens to an audio file in a mobile terminal through a WiFi earphone, when the head of the user moves or rotates, the current position parameters of the WiFi earphone obtained through a position sensor determine the rotating angle and direction of the head of the user, and the moving distance and direction, so that according to the virtual sound source position of the audio file in the brain of the user and the distance change between the left earphone and the right earphone and the sound source position caused by the change of the head position of the user, the volume of the left earphone and the right earphone in the WiFi earphone is respectively adjusted, and the volume change between the left earphone and the right earphone and the sound source position is consistent with the volume change caused by the change of the left earphone and the right earphone of the user, thereby truly simulating the listening scene of the audio file.

In this embodiment, after the mobile terminal and the WiFi headset are connected to each other through the first WiFi module 11 under the same WiFi network, the current position parameter of the WiFi headset is obtained through the information receiving module 12, then the audio file of the mobile terminal and the current position parameter of the WiFi headset are subjected to algorithm fusion through the first audio file processing module 13, and finally the audio file after the algorithm fusion is played through the WiFi headset through the audio sending module 14. Because the current position parameter of the WiFi headset corresponds to the head position of the user using the WiFi headset, when the head position of the user changes, the current position parameter of the WiFi headset also changes. When the head position of the user changes, the current position parameters of the audio file and the WiFi earphone are subjected to algorithm fusion and then played through the WiFi earphone, so that the sound source position of the virtual scene simulated by the audio file in the brain of the user is fixed, the hearing mode of the user in a real boundary is met, the hearing feeling of the user is more comfortable, and the playing quality of the audio file is improved. Moreover, as the data transmission rate of the WiFi network is faster, compared with the existing method for transmitting the audio file through Bluetooth, the WiFi network is more stable in transmitting the audio file, and the audio file is more smoothly played.

With continued reference to fig. 1, in another embodiment, the first WiFi module 11 in fig. 1 is connected to more than two WiFi headphones. Thereby enabling the audio files of the mobile terminal 10 to be played simultaneously in multiple WiFi headphones. Compared with the method that the audio file is played through the loudspeaker so that multiple users can listen to the same audio file at the same time, the audio playing scheme in the embodiment can effectively protect the privacy of the users and avoid affecting the lives of other people in the environment.

The first audio volume calibration unit 134 is configured to determine a left channel volume and a right channel volume of the audio file according to the reference play volume, the left volume offset and the right volume offset of the WiFi headset, so as to form an audio file after algorithm fusion.

In this embodiment, the first reference information obtaining unit 131 is used to calibrate the position sensor in the WiFi headset, and determine the reference position parameter and the reference playing volume of the WiFi headset; next, calculating, by the first position offset calculating unit 132, a position offset parameter of the WiFi headset according to the reference position parameter and the current position parameter of the WiFi headset; then, calculating the left volume offset and the right volume offset of the WiFi headset according to the position offset parameter of the WiFi headset by the first volume offset calculation unit 133; finally, the audio file is calibrated by the first audio volume calibration unit 134 according to the WiFi headset and the reference play volume, the left volume offset and the right volume offset, so as to form an audio file after algorithm fusion. Therefore, the volume of the left earphone and the right earphone in the WiFi earphone is adjusted according to the head position change of the user, and the sound source position of the simulated scene formed in the brain of the user is adjusted. For audio file playing matched with image watching, the user can accurately judge the sound source position in the virtual scene, and the sound source position is consistent with the real scene of the corresponding change of the sound source relative to the position of the user when the position of the user is changed, so that the listening experience of the user is more real, the accuracy of audio file scene simulation is improved, and the listening experience of the audio file of the user is better.
