Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, 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.
To make the objects, technical solutions and advantages of the present application more clear, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, an application scenario of audio transmission in the related art includes an audio source device 100 and an audio playback device 300. The user may watch video, make a phone call, play a game through the audio source device 100 to generate audio information. The audio information is transmitted to the audio playback device 300 through a standard communication protocol, and the audio playback device 300 plays the audio information. Taking the standard bluetooth protocol as an example, the standard bluetooth protocol may be an A2DP (Advanced audio distribution Profile, bluetooth audio transmission model protocol) protocol. Since the audio source device 100 and the audio playback device 300 can only establish communication connection through the standard communication protocol, and a large time delay is generated when audio information is transmitted through the standard communication protocol, the situation that audio and pictures are inconsistent occurs.
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 device 300. It can be seen that the time delay from the audio source device 100 emitting the audio information to the audio playback device 300 playing the audio information is T1-T0.
The sound source device 100 may be a mobile phone, a tablet computer, a PC (Personal computer), a wearable device, a Personal Digital Assistant (PDA), a vehicle-mounted device, an Augmented Reality (AR)/Virtual Reality (VR) device, a portable device (e.g., a laptop), an ultra-mobile Personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), or other devices capable of generating audio information.
The audio playing device 300 may be a sound box or an earphone.
Based on the above problem, an embodiment of the present application provides an electronic device, which includes a wireless Dongle, where the Dongle is configured to receive audio information sent by an audio source device, and send the audio information to an audio playing device. The audio information is transmitted between the Dongle and the sound source equipment through a standard communication protocol, and the audio information is transmitted between the Dongle and the audio playing equipment 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, the audio information is transmitted between the Dongle and the audio playing equipment through the private communication protocol, and the private communication protocol can have lower time delay relative to the standard communication protocol, so that the audio information is transmitted through the electronic equipment, the time delay of audio information transmission can be reduced, and the degree of sound and picture synchronization is improved.
Referring to fig. 3, an application scenario of audio transmission is provided in the embodiment of the present application. The audio source device 100, the electronic device 200, and the audio playback device 300 are included in the application scenario.
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 sends 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 sent to the audio playback device 300; at time T3, the audio information is transmitted to the audio playback device 300. It can be seen that the time delay from the audio source device 100 emitting the audio information to the audio playback device 300 playing the audio information is T3-T0.
Since the time T2-T0 required for the audio information to be emitted from the audio source device 100 to be transmitted to the electronic device 200 is very small, much smaller than T1-T0, and the time T3-T2 can be made short (for example, smaller than 20 msec) 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 time delay of playing the audio information by the audio playing device can be reduced by the electronic device with Dongle.
Referring to fig. 5, in an implementation manner, the electronic device 200 in the embodiment of the present application may include a Dongle circuit board 210 and a charging circuit board 220.

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 board 220, thereby charging the battery.
In another scenario, if the first interface is connected to the audio device, the Dongle function on the Dongle circuit board 210 is turned on to receive the audio information sent by the audio device 100 through the bluetooth chip and send the audio information to the audio playback device 300.
In 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 the external power into a preset voltage and outputs the preset voltage to the charging IC on the charging circuit board 220, thereby charging the battery.
In another scenario, when the audio playback device 300 needs to be charged, the audio playback device 300 and the electronic device 200 may be connected via a data line. For example, the charging interface of the audio playback device 300 and the first interface of the electronic device 200 are connected via 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, the electronic device 200 starts to charge the audio playback device 300. 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, so as to charge the audio playing device 300.

The Dongle circuit board 210 and the charging circuit board 220 form an integrated structure, and the electronic device 200 integrates the Dongle and the charging function.
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 circuit board 210 and the charging circuit board 220, and is used for controlling the operation mode of the electronic device 200. The operation modes of the electronic device 200 include: the Dongle circuit board 210 converts an external power supply 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 audio source device 100 and transmit the audio information to the audio playback device 300.
