Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of an audio data transmission method according to the present invention, in this embodiment, the audio data transmission method includes the following steps:
step S10: when an audio playing instruction is received, acquiring a first audio file corresponding to the audio playing instruction, and acquiring configuration information of a master sound box and configuration information of slave sound boxes;
in this embodiment, the audio data transmission method is applied to a sound box system, where the sound box system may include a master sound box and at least one slave sound box, and the master sound box may be connected to the at least one slave sound box through a near magnetic induction module, and the sound box system may be a 2.1 channel system, a 5.1 channel system, a 7.1 channel system, or the like. The near magnetic induction module can lead a plurality of sound boxes to work coordinately through the near magnetic field induction technology, thereby constructing a stereo environment. The Near Field Magnetic Induction (NFMI) is a short-range wireless technology, and performs communication by coupling a close low-power-consumption and non-propagating Magnetic Field between devices, and has the advantages of low power consumption, stable communication, strong anti-interference capability and the like compared with communication modes such as WIFI or bluetooth. And, the main audio amplifier can be any audio amplifier appointed in advance in the audio amplifier system, can confirm according to the particular case. For example, a sound box with a voice module in a sound box system can be used as a main sound box, so as to issue control instructions such as music playing and the like to the main sound box through voice; or the sound box closest to the user can be used as the main sound box; the main Sound box may be connected to the playback device in a wireless manner, such as Radio Frequency/infrared/bluetooth/Sound wave/WiFi/ZigBee/RFID (Radio Frequency Identification), or may be connected to the playback device in a wired manner through interfaces, such as line out (audio output interface), usb (Universal Serial Bus), I2S (Inter-IC Sound Bus, also called an integrated circuit built-in audio Bus), and the like; the playing device can be an audio playing device which can be connected with the main sound box, such as a television, a computer or a mobile phone.
Therefore, when the main sound box receives an audio playing instruction, a first audio file corresponding to the audio playing instruction needs to be acquired first, the audio playing instruction may be a voice instruction sent by a user or a playing instruction sent by a playing device, the manner in which the main sound box acquires the first audio file may be wired or wireless, and the first audio file may also be an audio file pre-stored in the main sound box or an audio file acquired by the main sound box from the internet. After the first audio file corresponding to the audio playing instruction is obtained, in order to determine a second audio file corresponding to the slave loudspeaker according to the obtained first audio file and send the second audio file to the corresponding slave loudspeaker to construct a stereo sound effect, configuration information of the master loudspeaker and configuration information of the slave loudspeaker are also required to be obtained, so that the second audio file corresponding to the slave loudspeaker is determined from the first audio file according to the configuration information of the master loudspeaker and the configuration information of the slave loudspeaker. The master sound box configuration information may include characteristic parameter information such as sound channel information, audio frequency information, sensitivity information, signal-to-noise ratio information and the like corresponding to the master sound box, and similarly, the slave sound box configuration information may include characteristic parameter information such as sound channel information, audio frequency information, sensitivity information, signal-to-noise ratio information and the like corresponding to the slave sound box; the mode of acquiring the configuration information of the master loudspeaker box and the configuration information of the slave loudspeaker boxes can be acquired from a pre-stored database, namely, the configuration information of the master loudspeaker box and the configuration information of the slave loudspeaker boxes can be stored in the database of the master loudspeaker box or the server in advance, and when an audio playing instruction is received, the configuration information of the master loudspeaker box and the configuration information of the slave loudspeaker boxes can be directly acquired from the database of the master loudspeaker box or the server; the method may further include automatically detecting a slave speaker connected to the master speaker through the near magnetic induction module when receiving an audio playing instruction, and then sending a configuration information request to the slave speaker through the near magnetic induction module to obtain the slave speaker configuration information, where the master speaker may autonomously report the master speaker configuration information, and the like.
In an embodiment, before the configuration information of the master speaker and the configuration information of the slave speakers are obtained, the configuration information of the master speaker may be generated according to the position information and the number information of the master speaker and the slave speakers in the speaker system and the size information of the active space of the speakers, and the configuration information of the slave speakers may be stored in a database of the master speaker or the server, so that the master speaker may obtain the configuration information of the slave speakers when receiving the audio playing instruction. Specifically, the position information of each sound box in the sound box system (including the relative position information between each sound box and the user and the relative position information between each sound box), the number information of the sound boxes in the sound box system, and the size information of the sound box action space may be obtained first, and then the master sound box and the slave sound boxes may be configured with parameters according to the obtained number information, position information, and size information, so as to obtain configured master sound box configuration information and slave sound box configuration information, and store the configured master sound box configuration information and slave sound box configuration information in the database of the master sound box or the server. For example, the number of channels may be determined according to the number information, corresponding channel information may be configured for different sound boxes based on the position information of each sound box, and audio frequency information corresponding to different sound boxes may be determined according to the relative position information of each sound box and a user or by combining the size information of the action space of the sound boxes and the relative position information between the sound boxes.
Step S20: determining a second audio file corresponding to the slave loudspeaker box from the first audio file according to the configuration information of the master loudspeaker box and the configuration information of the slave loudspeaker box;
after the first audio file corresponding to the audio playing instruction is obtained and the configuration information of the master loudspeaker box and the configuration information of the slave loudspeaker box are obtained, in order to enable the specified loudspeaker box in the loudspeaker box system to play the audio file corresponding to the specified loudspeaker box to construct a stereo effect, a second audio file corresponding to the slave loudspeaker box is determined from the first audio file according to the configuration information of the master loudspeaker box and the configuration information of the slave loudspeaker box, and the second audio file is transmitted to the slave loudspeaker box.
The manner of determining the second audio file corresponding to the slave loudspeaker from the first audio files according to the master loudspeaker configuration information and the slave loudspeaker configuration information may be: according to the configuration information of the master loudspeaker box and the configuration information of the slave loudspeaker boxes, decomposing the first audio file into third audio files corresponding to the master loudspeaker box and the slave loudspeaker boxes respectively, determining the third audio file corresponding to the slave loudspeaker boxes from the decomposed third audio files, and taking the third audio file as a second audio file corresponding to the slave loudspeaker boxes; the audio file of the master sound box and the audio file of the slave sound box can be distinguished from the first audio file according to the matching between the master sound box configuration information and the first audio file and the matching between the slave sound box configuration information and the first audio file, so that a second audio file and the like corresponding to the slave sound box are determined from the first audio file.
Step S30: transmitting a second audio file from the master sound box to the slave sound box by using the near magnetic induction module;
after determining a second audio file corresponding to the slave loudspeaker box from the first audio file, the second audio file needs to be transmitted to the slave loudspeaker box. The transmission mode can be wired mode or wireless mode, but wired mode is unfavorable for creating clean and tidy home environment, and wireless mode mostly adopts bluetooth or WIFI's form at present, and the audio file transmission through bluetooth or WIFI can have the problems such as the consumption height, communication stability is poor, interference killing feature is not strong, therefore, this embodiment provides a better implementation scheme, preferably transmits the second audio file through near magnetic induction module, with the second audio file from main audio amplifier to from the audio amplifier. Of course, when the near magnetic induction module is abnormal, the audio file of the sound box can be transmitted by switching to other communication modes according to the communication mode supported by the sound box system and the preset priority. If the sound box system supports near magnetic induction communication, WIFI, Bluetooth, wired communication and the like, according to a preset priority, if the near magnetic induction module is in the near magnetic induction, WIFI, Bluetooth and wired communication in sequence from high to low, the connection to the WIFI can be switched when the near magnetic induction module is abnormal. Wherein, different communication modes can correspond different communication modules, and different communication modules can exist alone, avoid mutual interference and be convenient for the fortune dimension, also can be integrated to same communication unit, reduce the volume of audio amplifier and reduce development cost.
In addition, in order to create a stereo effect, after the second audio file is transmitted from the master speaker to the slave speaker by using the near magnetic induction module, it is necessary to keep the master speaker and the slave speaker to play corresponding audio files synchronously. That is, according to the master speaker configuration information and the slave speaker configuration information, after determining the second audio file corresponding to the slave speaker from the first audio file, it also determines the fourth audio file corresponding to the master speaker from the first audio file, after the master speaker transmits the second audio file from the master speaker to the slave speaker through the near magnetic induction module, the slave speaker decodes the received second audio file and the master speaker also decodes the fourth audio file corresponding to the master speaker, after decoding, it can communicate through the near magnetic induction module to ensure that the master speaker and the slave speaker can synchronously play the corresponding audio files, so as to create a good stereo effect. Specifically, when receiving the second audio file from the sound box, the slave sound box sends feedback information to the master sound box, the master sound box sends a synchronous playing instruction to the slave sound box according to the received feedback information, and when receiving the synchronous playing instruction, the slave sound box synchronously plays the corresponding audio file with the master sound box; or after receiving the second audio file from the sound box, the slave sound box autonomously sends a synchronous playing request to the master sound box, when receiving the synchronous playing request, the master sound box sends a synchronous playing instruction to the slave sound box, and when receiving the synchronous playing instruction, the master sound box and the slave sound box simultaneously play the corresponding audio file. Considering the delay of information transmission, delay processing can be carried out according to the difference of transmission distance or transmission path and the like in the communication process so as to ensure that the slave loudspeaker box and the master loudspeaker box keep synchronous playing; or directly appointing the time of synchronous playing, and when the appointed time is reached, the master loudspeaker box and the slave loudspeaker boxes synchronously play corresponding audio files and the like.
In this embodiment, when an audio playing instruction is received, a first audio file corresponding to the audio playing instruction is acquired, configuration information of the master sound box and the slave sound box is acquired, the acquired first audio file is decomposed into at least two third audio files according to the configuration information of the master sound box and the slave sound box, a second audio file corresponding to the slave sound box is determined from the at least two third audio files, and then the second audio file is transmitted to the slave sound box by using the near magnetic induction module. Through nearly magnetic induction module with second audio file transmission extremely from the audio amplifier to guarantee the stability of transmission course and the reliability of transmission data, avoid the mode transmission through WIFI or bluetooth to lead to that the audio transmission effect is poor to cause the influence to output tone quality, improved audio transmission and tone quality effect.
Referring to fig. 3, fig. 3 is a flowchart illustrating an audio data transmission method according to a second embodiment of the present invention. A second embodiment of the audio data transmission method of the invention is proposed on the basis of the first embodiment. In this embodiment, the audio data transmission method includes the following steps:
step S11: when an audio playing instruction is received, acquiring a first audio file corresponding to the audio playing instruction, and acquiring configuration information of a master sound box and configuration information of slave sound boxes;
step S12: determining a second audio file corresponding to the slave loudspeaker box from the first audio file according to the configuration information of the master loudspeaker box and the configuration information of the slave loudspeaker box;
step S13: determining a transmission link for transmitting the second audio file;
step S14: and transmitting a second audio file from the main sound box to the slave sound box through the transmission link by using the near magnetic induction module.
After determining the second audio file corresponding to the slave loudspeaker box from the first audio file according to the configuration information of the master loudspeaker box and the configuration information of the slave loudspeaker box, if the second audio file corresponding to the slave loudspeaker box is to be transmitted to the slave loudspeaker box by using the near magnetic induction module, a transmission link for transmitting the second audio file is also required to be determined, so that the near magnetic induction module can transmit the second audio file corresponding to the slave loudspeaker box through the transmission link, the stability of data transmission is improved, and when a plurality of slave loudspeaker boxes exist, the mutual interference in the transmission of the second audio files corresponding to different slave loudspeaker boxes can be avoided. The method for determining the transmission link may be that a corresponding transmission link is allocated to the slave loudspeaker box in advance, and then the transmission link of the second audio file corresponding to the slave loudspeaker box is determined according to the link information of the transmission link allocated in advance; the configuration of different transmission links may be based on the distance information required for transmitting the second audio file and the configuration information of the slave loudspeaker box.
Therefore, when only one slave loudspeaker box exists, at this time, the transmission link corresponding to the slave loudspeaker box may be one of the multiple links allocated in advance, or only one transmission link may be allocated in advance, and specifically, allocation may be performed according to application requirements, for example, a link with a high transmission speed may be allocated to the slave loudspeaker box in order to improve the transmission efficiency of the audio file; in order to ensure the reliability of audio file transmission, a plurality of links may be allocated to the slave loudspeaker box, so that when one of the links fails, the transmission of the audio file may be completed through the other links, and so on. However, when there are multiple slave speakers, if multiple second audio files are to be simultaneously transmitted to corresponding slave speakers, different transmission links need to be set for the second audio files corresponding to different slave speakers, so as to achieve synchronous transmission of different second audio files and avoid mutual interference between different second audio files, where different transmission links may correspond to different magnetic field bands. Specifically, the transmission link of the second audio file corresponding to the different slave speakers may be set according to a preset rule, where the preset rule may be a setting rule corresponding to file information (file type, file size, and the like) of the second audio file, or a setting rule corresponding to a transmission distance and/or a transmission direction.
In an embodiment, the preset rule may be a setting rule corresponding to a file type of the second audio file, that is, transmission links may be allocated to the different second audio files corresponding to the slave speakers according to the file types corresponding to the different second audio files, so that the different types of second audio files are transmitted through the different transmission links, and mutual interference between the different types of second audio files is avoided. If the second audio file is a left channel audio file, setting a left channel audio transmission link for the left channel audio file; if the second audio file is a right channel audio file, setting a right channel audio transmission link for the right channel audio file; if the second audio file is a high-frequency audio file, setting a corresponding high-frequency audio transmission link for the high-frequency audio file; if the second audio file is a low-frequency audio file, setting a corresponding low-frequency audio transmission link for the low-frequency audio file; if the second audio file is a left channel high-frequency file, setting a corresponding left channel high-frequency audio transmission link for the left channel high-frequency file, that is, different file types correspond to different transmission links, and different second audio files correspond to different file types.
In another embodiment, the preset rule may be a setting rule corresponding to the transmission distance and/or the transmission direction, that is, the transmission links may be set for different second audio files according to the position information of different slave speakers (which may include direction information and distance information with respect to the master speaker). Generally, different loudspeaker box systems can adopt different placement rules, such as a regular triangle placement method, an axis inner side placement method, a diamond placement method and the like, and the placement positions of the loudspeaker boxes in the different placement rules are different, so that transmission links can be set according to the position information of the slave loudspeaker boxes relative to the master loudspeaker box, the loudspeaker box system is suitable for different loudspeaker box systems and different placement rules, and the transmission links corresponding to different second audio files are ensured to be single. For example, the opposite direction of the master loudspeaker boxes may be used as a starting point, and the preset angle may be used as an interval to set corresponding transmission links for different slave loudspeaker boxes, where the preset angle may be set according to actual conditions (e.g., the number of slave loudspeaker boxes, the arrangement density of the slave loudspeaker boxes, etc.). If the preset angle is 30 degrees, the opposite direction of the main loudspeaker box is taken as a starting point, a first transmission link is arranged for the auxiliary loudspeaker boxes within the range of 30 degrees clockwise, a second transmission link is arranged for the auxiliary loudspeaker boxes within the range of 30 degrees to 60 degrees, a third transmission link is arranged for the auxiliary loudspeaker boxes within the range of 60 degrees to 90 degrees, and the like, wherein each transmission link only corresponds to one auxiliary loudspeaker box, namely the setting of the preset angle needs to ensure that only one auxiliary loudspeaker box exists within each angle range. Of course, the preset rule may also be that different transmission links are set according to the distance information of the slave loudspeaker box relative to the master loudspeaker box, or by combining the position information of the slave loudspeaker box and the distance information of the slave loudspeaker box relative to the master loudspeaker box, and the like, and the setting is not specifically limited herein.
In this way, different transmission links are set for different second audio files of the slave loudspeaker boxes in advance, and the transmission links of the second audio files corresponding to different slave loudspeaker boxes can be determined according to the file types of the corresponding second audio files or the position information of the slave loudspeaker boxes. If the file type of the second audio file is a left channel audio file, determining that a transmission link corresponding to the second audio file is a left channel audio transmission link according to a preset rule; or, when the slave loudspeaker box is in a range of 30 degrees to 60 degrees relative to the master loudspeaker box, determining that the transmission link of the second audio file corresponding to the slave loudspeaker box is a second transmission link according to a preset rule, and the like.
