Technical Field
[0001] This application relates to the field of live streaming, and more particularly to an adapter board and electronic device for multi-functional live streaming. Background Technology
[0002] An adapter board is an electronic device used to connect interfaces of different specifications or types of devices to achieve signal conversion and data transmission. Adapter boards are used in live streaming scenarios to adapt to different devices; their core function is to connect electronic device interfaces of different specifications or types. This type of adapter is particularly important in the live streaming field, as it can solve the problem of interface incompatibility between devices during live streaming, ensuring smooth signal transmission and thus achieving high-quality live streaming results.
[0003] However, current live streaming adapters can only meet single-function requirements. For example, they may only support Type-C interfaces, or only Lightning interfaces, or only be compatible with professional live streaming equipment, or only support simple 3.5mm headphone recording and live streaming. Therefore, they cannot meet the diverse functional needs of users in the live streaming industry. Utility Model Content
[0004] In view of this, this application provides an adapter board and electronic device for multi-functional live streaming.

[0023] Figure 1 This is a schematic diagram of the circuit structure of an adapter board provided in an embodiment of this application.
[0024] Figure 2This is a schematic diagram of the circuit structure of a recording adjustment circuit provided in an embodiment of this application.
[0025] Figure 3 This is a schematic diagram of an adapter board provided in an embodiment of this application. Detailed Implementation
[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] First, we will explain the proper nouns that may be used in this article.
[0028] Adapter board:
[0029] Adapter boards typically integrate multiple signal conversion circuits, capable of converting signals from one interface into signals that can be recognized by another. This conversion process ensures effective communication and data transmission between different devices.
[0030] In live streaming scenarios, broadcasters may need to connect various devices, such as cameras, microphones, and monitors. These devices may have different interface types, such as HDMI, USB, and 3.5mm audio. Adapter boards can connect these devices with different interfaces, ensuring smooth signal transmission.
[0031] However, as mentioned in the background section, while there are various types of live streaming devices on the market, they generally only meet single-function requirements. Some only support Type-C interfaces, others only Lightning interfaces, some only support professional live streaming equipment, and others only support simple 3.5mm headphone recording and live streaming. Consumers are forced to purchase multiple live streaming devices to meet their needs.
[0032] To address the aforementioned issues, this application proposes an adapter board for multi-functional live streaming. This adapter board not only supports live streaming using professional live streaming equipment but also allows live streaming using ordinary 3.5mm headphones, and supports simultaneous charging and live streaming via multiple interfaces. This adapter board offers broader compatibility with live streaming audiences and venues, thus expanding its application scope.
[0033] The circuit structure of the adapter board of this application is described below with reference to the accompanying drawings. Among them, Figure 1 A schematic diagram of the circuit structure of an adapter board 100 provided in an embodiment of this application is shown.
[0034] like Figure 1As shown, the adapter board 100 includes a charging circuit 110, a recording adjustment circuit 120, and multiple interface female connectors 130. Figure 1 Only two are shown in the example; this application does not limit the number of interface female connectors 130. The interface female connector 130 is used to connect interface devices with multiple interface types, which may include at least one of Type-C, USB-A, and Lightning interfaces.
[0035] The charging circuit 110 can be used to charge electronic devices connected to the adapter board 100 via a charging protocol such as Power Delivery (PD). Figure 1 As shown, the charging circuit 110 includes a charging chip 111 and a charging socket 112. The charging socket 112 is used to connect to a charger and is connected to the charging chip 111.
[0036] In addition, the charging chip 111 can be connected to the multiple interface sockets 130, for example, by communicating the charging speed with the multiple interface sockets 130 through the CC signal (such as CC1 / CC2) pin, and then charging the electronic devices connected to the interface sockets 130 after the communication is completed.
[0037] Optionally, in some embodiments, the charging circuit 110 may include a boost / buck power supply circuit 113. This boost / buck power supply circuit 113 can be used to supply power to the charging chip 111 and other chips in the adapter board 100 (such as…). Figure 1 The audio chip 121 in the circuit provides an operating voltage (e.g., 5V). One end of the boost / buck power supply circuit 113 is connected to one end of the plurality of interface females (e.g., VBUS), another end is connected to one end of the charging female (e.g., VBUS), and yet another end is connected to the output of the charging chip.
[0038] like Figure 1 As shown, the recording adjustment circuit includes an audio chip 121, at least one audio input female connector 122, at least one audio output female connector 123, a first adjustment knob 124, and a second adjustment knob 125.
[0039] Specifically, the at least one audio input female connector 122 is used to receive audio input, and the at least one audio output female connector 123 is used for audio output. The at least one audio output female connector 123 can be connected to an in-ear monitor and / or a host terminal.
[0040] like Figure 1As shown, the first adjustment knob 124 is connected to at least one audio input female connector 122 to adjust the volume of audio data recorded to the earpiece. Furthermore, the first adjustment knob 124 is connected to at least one audio output female connector 123 to adjust the volume of audio data output to the earpiece. Thus, the volume of all input audio can be adjusted before being transmitted to the earpiece female connector, allowing the broadcaster to monitor the recording effect in real time, and to adjust the volume of the live monitoring in real time, or to mute it. In addition, the second adjustment knob 125 is connected to at least one audio input female connector 122 to adjust the volume of audio recorded to the audio chip 121, thereby adjusting the volume transmitted by the audio chip 121 to the host device, and is also connected to at least one audio output female connector 123 to adjust the volume of audio data output to the host. Thus, the volume of all input audio can be adjusted before being transmitted to the earpiece audio chip 121, which then transmits the adjusted audio to the host device such as a mobile phone, allowing for real-time adjustment of the volume at the viewer's end, or to mute it.
[0041] In some embodiments, the audio chip 121 can communicate with electronic devices connected to the plurality of interface sockets 130 via the D+ / D- pins to transmit audio data.
[0042] In some embodiments, the first adjustment knob 124 and / or the second adjustment knob 125 include a sliding potentiometer for adjusting the resistance value to adjust the volume gain of the audio input / output (such as microphone input, line input, or detection output) in real time. For example, the sliding potentiometer controls the change in the internal resistance value via the knob, changing the current or voltage in the circuit to achieve volume adjustment (analog signal control). Its physical structure may include a sliding metal contact that moves on a resistive material (such as a carbon film), the position of which determines the resistance value, thereby affecting the signal strength.
[0043] In one possible implementation of the first aspect described above, the audio input includes a line-in input or a passive microphone (MIC) input.
[0044] Figure 2 A schematic diagram of another recording adjustment circuit 200 provided in an embodiment of this application is shown. Figure 2 As shown, in addition to the audio chip 121, at least one audio input female 122, at least one audio output female 123, the first adjustment knob 124 and the second adjustment knob 125, the recording adjustment circuit 200 may also include a first operational amplifier (OPA) chip 210, a second OPA chip 220 and a first switch chip 230.
[0045] In some embodiments, such as Figure 2As shown, one end of the first OPA chip is connected to the first adjustment knob 124 to amplify and adjust the volume of the audio data output by the first adjustment knob 124 to the earphone monitor, and the other end is connected to the audio chip 121 and the at least one audio output female 123 to amplify and adjust the volume of the audio data output by the audio chip 121 to the at least one audio output female 123.
[0046] In some embodiments, the second OPA chip 220 is connected to the at least one audio input female connector 122 to couple the at least one audio input female connector 122.
[0047] In some embodiments, the first audio input female 126 can be used for a first type of audio input (such as either a line-in input or a passive microphone input), and the first audio output female 127 can be used for both audio output and the first type of audio input. In other words, some audio output females can also be used for audio input. Furthermore, as... Figure 2 As shown, the first switch chip 230 is connected to the first audio output female connector 126 and the first audio input female connector 127. When the first audio input female connector 126 receives the first type of audio input, the first switch chip 230 disables the first type of audio input function of the first audio output female connector 127; when the first audio input female connector 126 does not receive the first type of audio input, the first switch chip 230 enables the first type of audio input function of the first audio output female connector 127.
[0048] Figure 3 A schematic diagram illustrating a specific example of a conversion board 300 provided in an embodiment of this application is shown.
[0049] like Figure 3 As shown, corresponding to Figure 1 The system includes multiple female connectors 130. In this embodiment, it can support uplink interfaces for two Type-C female connectors. Type-C female connector 320 supports common Type-C uplink ports and USB-A uplink ports, while Type-C female connector 325 supports Lightning uplink ports. Furthermore, Type-C female connectors 320 and 325 can communicate via CC1 / CC2 using the power delivery (PD) protocol for charging, and via D+ / D- for audio data transmission.
[0050] Corresponding to Figure 1The first adjustment knob 124 and the second adjustment knob 125 shown are integrated into knobs 310 and 315 in this embodiment. Knob 310 adjusts the recording volume for the broadcaster's monitoring, while knob 315 adjusts the recording volume for the live stream audience. Knob 310 and knob 315 can adjust the resistance value of the sliding potentiometer, thereby adjusting the signal strength.
[0051] Corresponding to Figure 1 The audio input female connector 122 and audio output female connector 127 shown in this embodiment are integrated with audio input female connector 370, audio input female connector 375, and audio output female connector 380. Audio input female connector 370 supports line-in audio input and is compatible with various line-out audio inputs. Audio input female connector 375 supports passive microphone input and is compatible with various passive microphone inputs. Audio output female connector 380 supports in-ear monitoring and playback from HOST devices such as mobile phones. Furthermore... Figure 3 The audio chip 330 shown can upload recording data to devices such as mobile phones and play the audio from the mobile phones and other devices to the audio output socket 380.
[0052] In addition, corresponding to Figure 2 The first audio output female 127 shown can also support passive microphone input. Furthermore, corresponding to... Figure 2 The first switch chip 230 shown in this embodiment also integrates an analog switch chip 365. This analog switch chip 365 can isolate and enable the passive MIC audio signal of the audio output socket 380. The control signal for whether the signal is enabled or disabled comes from whether a device is plugged into or unplugged from the audio input socket 375. If a device is plugged in, the signal will be disabled; otherwise, the signal will be enabled. For example, when a MIC is plugged into the audio input socket 375, the audio output socket 380 will not support the input of a passive MIC.
[0053] In some embodiments, corresponding to Figure 1 The charging socket 112 shown in this application embodiment can also integrate a charging port such as... Figure 3 The Type-C female connector 390 shown supports a maximum input of 60W, allowing devices to charge at a maximum power of 60W. The PD protocol charging chip 340 can connect via the CC signal line... Figure 3 The three Type-C female ports communicate their charging speeds, and after communication is complete, the charging and step-down power supply module 335 controls the charging and charging of the device. The 5V operating power required by the entire system can be provided by the PD protocol charging chip 340 controlling the charging and step-down power supply module 335.
[0054] Corresponding to the first OPA chip 210 and the second OPA chip 220, such as Figure 3As shown, this embodiment integrates OPA chip 345 and OPA chip 350. OPA chip 345 can amplify and adjust the playback data output by audio chip 330, and amplify the recorded audio data passed through knob 310 before outputting it to audio output socket 380. OPA chip 350 amplifies the recorded audio data from the passive microphones of audio input socket 375 and audio output socket 380 and couples it to audio input socket 370.
[0055] The conversion board 300 shown in the embodiments of this application is compatible with both Type-C and Lightning interfaces, supports both Line-in interface input and passive microphone input, allows independent sliding adjustment of recording volume and earphone monitoring volume, and has a charging function, thus meeting the needs of live streaming while charging.
[0056] It is worth noting that this application embodiment does not limit the number of female connectors (such as interface female connectors, audio input female connectors, and audio output female connectors) or the number of chips (such as charging chips, audio chips, and switch chips).
[0057] It should be noted that in the examples and description of this patent, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0058] Although this application has been illustrated and described with reference to certain preferred embodiments thereof, those skilled in the art should understand that various changes in form and detail may be made thereto without departing from the spirit and scope of this application.
