Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following description will be made with reference to the accompanying drawings by way of specific embodiments.
Referring to fig. 1, an application scenario of audio transmission in the related art includes a sound source device 100 and an audio playback device 300. The user can watch video, make a call, play a game, and thereby generate audio information through the audio source device 100. The audio information is transmitted to the audio playback device 300 via a standard communication protocol, and the audio playback device 300 plays the audio information. Taking the standard bluetooth protocol as an example, an A2DP (Advanced AudioDistribution Profile, bluetooth audio transmission model protocol) protocol may be used. Since the communication connection between the audio source device 100 and the audio playback device 300 can be established only by the standard communication protocol, the transmission of audio information by the standard communication protocol generates a large time delay, which results in inconsistent audio and images.
As shown in fig. 2, at time T0, the sound source device 100 emits audio information; at time T1, the audio information is transmitted to the audio playback apparatus 300. It can be seen that the time delay from the audio source device 100 to the audio playback device 300 for playing back the audio information is T1-T0.
The audio source device 100 may be a mobile phone, a tablet computer, a PC (personal computer, a personal computer), a wearable device, a personal digital assistant (Personal Digital Assistant, PDA), an in-vehicle device, an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, a portable device (e.g., a portable computer), a super mobile personal computer (ultra-mobile personalcomputer, UMPC), a netbook, a personal digital assistant (personal digital assistant, PDA), or a device capable of generating audio information.
The audio playing device 300 may be a speaker or a headphone.
In view of the above, an embodiment of the present application provides an electronic device, including a wireless Dongle, where the Dongle is configured to receive audio information sent by a radio device, and send the audio information to an audio playing device. The audio information is transmitted between the Dongle and the audio source device through a standard communication protocol, and the audio information is transmitted between the Dongle and the audio playing device through a private communication protocol.
According to the electronic equipment, the audio information is transmitted between the Dongle and the sound source equipment through the standard communication protocol, and the audio information is transmitted between the Dongle and the audio playing equipment through the private communication protocol.
Referring to fig. 3, an application scenario of audio transmission is provided in an embodiment of the present application. The application scene includes the audio source device 100, the electronic device 200, and the audio playback device 300.
The electronic device 200 is capable of establishing a communication connection, such as a bluetooth connection, with the audio source device 100 and the audio playback device 300. The sound source device 100 transmits audio information to the electronic device 200, and the electronic device 200 receives the audio information through a standard communication protocol. The electronic device 200 then transmits the audio information to the audio playback device via the private communication protocol.
Referring to fig. 4, at time T0, the sound source device 100 emits audio information; at time T2, the audio information is transmitted to the electronic device 200, and the audio information is transmitted to the audio playback device 300; at time T3, the audio information is transmitted to the audio playback apparatus 300. It can be seen that the time delay from the audio source device 100 to the audio playback device 300 for playing back the audio information is T3-T0.
Since the time T2-T0 required for the audio information to be emitted from the sound source device 100 to be transmitted to the electronic device 200 is very small, much smaller than T1-T0, and the time of T3-T2 can be made very short (for example, smaller than 20 milliseconds) by the private communication protocol, the time length of T3-T0 can be smaller than the time length of T1-T0. That is, in the embodiment of the present application, the delay of playing the audio information by the audio playing device can be reduced by the electronic device with a Dongle.
Referring to fig. 5, in one implementation, an electronic device 200 in an embodiment of the present application may include a Dongle circuit board 210 and a charging circuit board 220.

The first interface is used for being electrically connected with an external power supply or sound source equipment, the second interface is electrically connected with a charging IC, and the charging IC is electrically connected with a battery.
In one scenario, if the first interface is connected to an external power source, the Dongle 210 converts the external power source into a predetermined voltage (e.g., 5V) and outputs the predetermined voltage to the charging IC on the charging circuit 220, thereby charging the battery.
In yet another scenario, if the first interface is connected to the audio source device, the Dongle function on the Dongle circuit board 210 is turned on to receive the audio information sent by the audio source device 100 through the bluetooth chip and send the audio information to the audio playback device 300.
In still another scenario, if the first interface is connected to the audio source device 100, the Dongle function on the Dongle circuit board 210 is turned on to receive the audio information sent by the audio source device 100 through the bluetooth chip and send the audio information to the audio playing device 300; meanwhile, the Dongle circuit board 210 converts an external power source into a predetermined voltage and outputs the predetermined voltage to the charging IC on the charging circuit board 220, thereby charging the battery.
In yet another scenario, the audio playback device 300 and the electronic device 200 may be connected via a data line when the audio playback device 300 needs to be charged. For example, the charging interface of the audio playback apparatus 300 and the first interface of the electronic apparatus 200 are connected by a data line. After the electronic device 200 detects that the audio playback device 300 is connected to the electronic device 200 through the data line, charging of the audio playback device 300 is started. The battery transmits the electric energy to the first interface through the second interface of the charging IC and the Dongle circuit board 210, and then outputs the electric energy to the audio playing device 300 through the data line to charge the audio playing device 300.
Referring to fig. 5, the electronic device 200 may further include an interposer 230, and the dongle circuit board 210 is connected with the charging circuit board 220 through the interposer 230.

The Dongle circuit board 210 and the charging circuit board 220 form an integral structure, and the electronic device 200 integrates Dongle and charging functions.
In some embodiments, a function switching key may be disposed on the housing of the electronic device 200. The function switching key is connected to the Dongle 210 and the charging circuit 220, and is used to control the operation mode of the electronic device 200. The operating modes of the electronic device 200 include: the Dongle circuit board 210 converts an external power source into a preset voltage and outputs the preset voltage to the charging IC on the charging circuit board 220, thereby charging the battery; the Dongle on the Dongle circuit board 210 is turned on to receive the audio information transmitted from the sound source device 100 and transmit the audio information to the audio playback device 300.
In some embodiments, the bluetooth chip may include an Audio information receiving unit, an LE Audio chip, and a bluetooth transmission unit, where the LE Audio chip is provided with an encoding and decoding unit, and the Audio information receiving unit, the encoding and decoding unit, and the bluetooth transmission unit are sequentially connected.

According to the embodiment of the application, the encoding and decoding unit encodes the received Audio information through the LC3 algorithm, and the LC3 algorithm has a higher compression ratio, so that the transmission time of the Audio information can be greatly reduced, and meanwhile, the LE Audio chip can also improve the Audio quality, so that the Audio quality of the Audio played by the Audio playing equipment is improved, and the Hi-Res is supported.
