[0001] This invention belongs to the field of audio technology and relates to a voice terminal with multiple voice scene switching and its control method. Background Technology

[0002] As a standard module of the display and control computer, the voice terminal provides a unified interface for the display and control computer to listen to and transmit voice devices, and also has the function of connecting to the Internet for internal and external telephone communication.

[0003] In related technologies, since the voice terminal is embedded in the display and control computer, it needs to meet the needs of both the voice terminal itself for calls and the voice use on the display and control computer. At the same time, it also needs to accept and switch between various audio devices such as headsets, microphones, and local microphones. Without a complete voice switching solution, it is easy to cause abnormal voice loss or abnormality, affecting the normal operation of the function. Summary of the Invention

[0004] The purpose of this application is to provide a voice terminal that allows for switching between multiple voice scenarios, aiming to solve the problem of difficulty in switching voices under various voice usage scenarios.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows.

[0006] The technical solution of this application is to provide a voice terminal with multiple voice scene switching, including: a processor, an audio chip, an audio switching module, a communication module and an interface module. The interface module includes a first audio interface and a second audio interface. The interface module is also connected to the display and control computer and the audio chip respectively through the audio switching module.

[0007] The processor is connected to the audio chip and the communication module respectively, and the audio signal from the audio chip is connected to the network after passing through the processor and the communication module;

[0008] The audio switching module includes at least one switch. The processor controls each switch to be in a first state according to the detected connection status of the interface module, so that the first audio interface is connected to the display and control computer for audio signal connection, and the second audio interface is connected to the audio chip for audio signal connection.

[0009] It also includes a switching button connected to the processor. The processor controls each switching switch to be in the second state according to the instruction signal of the switching button, so that the second audio interface is connected to the display and control computer for audio signal connection, and the first audio interface is connected to the audio chip for audio signal connection.

[0010] The voice terminal of this application uses an audio switching module to switch the input and output audio signals of the first and second audio interfaces between the display and control computer and the voice terminal.

[0011] By default, the audio switching module's switch is in the first state, where the audio transceiver of the first audio interface is used by the display and control computer, and the audio transceiver of the second audio interface is used by the voice terminal. When the switch button is pressed, the audio switching module's switch is switched to the second state, allowing the audio transceiver of the first audio interface to be used by the voice terminal and the audio transceiver of the second audio interface to be used by the display and control computer.

[0012] The voice terminal also connects to the Internet via a processor and communication module, transmitting its audio signals to other voice terminals to enable voice call functionality between them.

[0013] In one embodiment of this technical solution, both the first audio interface and the second audio interface are used to connect an audio transceiver unit that includes a microphone and a speaker. The audio transceiver unit is a handset microphone, a headset, or a microphone with a speaker.

[0014] In one embodiment of this technical solution, the switching switch is a single-pole double-throw relay or a double-pole double-throw relay.

[0015] In one embodiment of this technical solution, the processor is model LS2K1000, and the audio switching module includes four switching switches, which are relays.

[0016] The processor's GPIO7 pin is connected to the detection terminal of the first audio interface to detect whether there is an audio transceiver component in the first audio interface, and its GPIO8 pin is connected to the detection terminal of the second audio interface to detect whether there is an audio transceiver component in the second audio interface.

[0017] The processor's GPIO2, GPIO3, GPIO4, and GPIO5 pins are respectively connected to the coil pins of four switching switches to control the switching switches;

[0018] The processor's GPIO1 pin is connected to the toggle button, and the USB_DP and USB_DM pins are connected to the audio chip via the USB bus.

[0019] In one embodiment of this technical solution, the switching switch adopts a double-pole double-throw relay, wherein:

[0020] The two common terminals of the first switching switch are respectively connected to the audio signal input terminals of the first audio interface and the second audio interface. The two normally closed terminals are respectively connected to the audio signal input terminal of the display control computer and the audio chip, and the two normally open terminals are respectively connected to the audio signal input terminal of the display control computer and the audio chip, thereby realizing the switching of the audio signal input of the first audio interface and the second audio interface between the display control computer and the audio chip.

[0021] The two common terminals of the second switch are respectively connected to the audio signal output terminals of the display and control computer, and the two normally closed terminals are respectively connected to the two normally closed terminals of the third switch, and the two normally open terminals are respectively connected to the two normally open terminals of the fourth switch; the two common terminals of the third switch are respectively connected to the signal output terminals of the first audio interface, and the two normally open terminals are connected to the audio chip; the two common terminals of the fourth switch are respectively connected to the signal output terminals of the second audio interface, and the two normally closed terminals are connected to the audio chip, thereby realizing the switching of audio signal output between the display and control computer and the audio chip between the first audio interface and the second audio interface.

[0022] In one embodiment of this technical solution, the audio chip is model AP8248A2, and the internal channels of the audio chip are switched through software configuration;

[0023] The LINEIN1R pin of the audio chip is connected to the first switch and is used to receive audio signal input from the first audio interface and the second audio interface; its DAC_R pin and DAC_L pin are respectively connected to the two normally open terminals of the third switch and to the two normally closed terminals of the fourth switch.

[0024] In one embodiment of this technical solution, a local microphone and a local speaker are also included. The local microphone is connected to the LINEIN1R pin of the audio chip after passing through an operational amplifier, and the local speaker is connected to the DAC_X pin of the audio chip after passing through a power amplifier.

[0025] In one embodiment of this technical solution, the processor detects that the GPIO1 pin is connected to the power supply VCC through the first resistor R1 and is connected to one end of the switch button K5. The other end of the switch button K5 is grounded to GND. When the switch button is pressed, the processor's GPIO1 pin is at a low level.

[0026] The processor's GPIO7 pin is connected to the power supply VCC through the second resistor R2 and is also connected to the detection terminal of the first audio interface. When the first audio interface has an audio transceiver component, the detection terminal is connected to the ground terminal GND, making the processor's GPIO7 pin low.

[0027] The processor's GPIO8 pin is connected to the power supply VCC via the third resistor R3 and is also connected to the detection terminal of the second audio interface. When the second audio interface has an audio transceiver component, the detection terminal is connected to the ground terminal GND, making the processor's GPIO8 pin low.

[0028] In one embodiment of this technical solution, when the processor's GPIO7 pin is low and / or GPIO8 pin is low, the processor's GPIO2 pin, GPIO3 pin, GPIO4 pin and GPIO5 pin are set to high, so that all four toggle switches are switched to the first state.

[0029] When the processor's GPIO1 pin is low, the processor's GPIO2, GPIO3, GPIO4 and GPIO5 pins are also set to low, so that all four toggle switches are switched to the second state.

[0030] Another technical solution of this application is to provide a control method for a voice terminal that switches between multiple voice scenarios, including the following steps:

[0031] The processor detects whether the first audio interface is connected;

[0032] The processor detects whether the second audio interface is connected;

[0033] The processor controls each switch to be in the first state according to the detected connection status of the first audio interface or the second audio interface, so that the first audio interface is connected to the display and control computer for audio signal connection, and the second audio interface is connected to the audio chip for audio signal connection.

[0034] The processor controls each switch to the second state according to the instruction signal of the switching button, so that the second audio interface is connected to the display and control computer for audio signal connection, and the first audio interface is connected to the audio chip for audio signal connection.

[0052] The technical solutions of some 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.

[0053] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a voice terminal with multiple voice scene switching, including a processor, an audio chip, an audio switching module, a communication module, and an interface module. The processor is connected to the audio chip and the communication module respectively, and the audio signal of the audio chip is connected to the network after passing through the processor and the communication module.

[0054] like Figure 1 As shown, the interface module includes a first audio interface and a second audio interface. The interface module is also connected to the display and control computer and the audio chip respectively through an audio switching module. Both the first audio interface and the second audio interface are used to connect to an audio transceiver component that includes a microphone and a speaker. The audio transceiver component can be a handset microphone, a headset, or a microphone with a speaker. The first audio interface and the second audio interface can be two identical interfaces selected from RSA interface, TRS interface, XLR interface, headphone interface, coaxial interface, optical fiber interface, or HDMI interface, or they can be two different interfaces.

[0055] In this embodiment, the structure and working principle of the voice terminal are explained by taking the example of connecting the first audio interface to the headset and the second audio interface to the handset microphone.

[0056] like Figure 4 and Figure 5 As shown, the CPU of the processor is model LS2K1000, and the audio chip is model AP8248A2 audio CODEC chip. The input and output of the audio chip can be switched through the internal channels of the audio CODEC. The audio CODEC chip is an audio chip with three ADCs (analog-to-digital converters) and two DACs (digital-to-analog converters). The internal channels can be switched arbitrarily through software configuration to realize the switching of multiple voice scenarios such as headset, handset microphone, local microphone and speaker.

[0057] The communication module of the voice terminal includes a network chip and a network interface. The communication module is used to connect the voice terminal to the network and interconnect it with the network of the display and control computer. The network of the display and control computer is then connected to a switch to ensure local area network communication between the display and control computers. In addition, it can also connect to the Internet through the switch. The display and control computer provides 12V power to the voice terminal to ensure that the voice terminal is powered on normally and the network can be pinged, that is, it is powered on and running normally.

[0058] The audio switching module includes four switching switches, which are double-pole double-throw relays. In other embodiments, the switching switches can also be single-pole double-throw relays, but more relays are required. Each switching switch is a dual-channel relay with two common terminals S1 and S2 and normally closed terminals S1A, S2A and normally open terminals S1B, S2B corresponding to each common terminal. One coil pin of the switching switch is connected to the power supply VCC, and the other is connected to the collector of a transistor. The emitter of the transistor is grounded, and its base is connected to a pin of the processor.

[0059] like Figures 9 to 13 As shown, specifically, the common terminal S1 of one path of the first switch K1 is connected to the audio signal input terminal HAND_MIC of the second audio interface, i.e., connected to the microphone of the handset microphone. Its normally closed terminal S1A is connected to the audio signal input terminal XK_MIC of the display and control calculator, and its normally open terminal S1B is connected to the LINEIN1R pin of the audio chip. The common terminal S2 of the other path of the first switch K1 is connected to the audio signal input terminal HP_MIC of the first audio interface, i.e., connected to the microphone of the headset. Its normally closed terminal S2A is connected to the LINEIN1R pin of the audio chip, and its normally open terminal S2B is connected to the audio signal input terminal XK_MIC of the display and control calculator. One coil pin of the first switch K1 is connected to the power supply VCC, and the other is connected to the collector of the transistor Q1. The emitter of the transistor is grounded, and its base is connected to the GPIO2 pin of the processor.

[0060] The common terminal S1 of one path of the second switch K2 is connected to the audio output terminal XK_LOUT_L of the left channel of the display and control computer, and the common terminal S2 of the other path is connected to the audio output terminal XK_LOUT_R of the right channel of the display and control computer. Its normally closed terminal S1A is connected to the normally closed terminal S2A of the third switch K3, and its normally open terminal S1B is connected to the normally open terminal S2B of the fourth switch K4. One coil pin of the second switch K2 is connected to the power supply VCC, and the other is connected to the collector of the transistor Q2. The emitter of the transistor is grounded, and its base is connected to the GPIO3 pin of the processor.

[0061] One common terminal S1 of the third switch K3 is connected to the right channel audio signal output terminal HP_LOUT_R of the first audio interface, and its normally open terminal S1B is connected to the DAC_R pin of the audio chip via an amplifier. The other common terminal S2 is connected to the left channel audio signal output terminal HP_LOUT_L of the first audio interface, and its normally open terminal S2B is connected to the DAC_L pin of the audio chip. One coil pin of the third switch K3 is connected to the power supply VCC, and the other is connected to the collector of transistor Q3. The emitter of the transistor is grounded, and its base is connected to the GPIO4 pin of the processor.

[0062] One common terminal S1 of the fourth switch K4 is connected to the right channel audio signal output terminal HAND_LOUT_R of the second audio interface, and its normally closed terminal S1A is connected to the DAC_R pin of the audio chip via an amplifier. The other common terminal S2 is connected to the left channel audio signal output terminal HAND_LOUT_L of the second audio interface, and its normally closed terminal S2A is connected to the DAC_L pin of the audio chip. One coil pin of the fourth switch K3 is connected to the power supply VCC, and the other is connected to the collector of transistor Q4. The emitter of the transistor is grounded, and its base is connected to the GPIO5 pin of the processor.

[0063] The first switch K1 switches the audio signal input from the first audio interface and the second audio interface to the display and control computer and the audio chip; the second switch K2 switches the audio signal output from the display and control computer to the third switch K3 and the fourth switch K4. The third switch K3 switches the two audio signal outputs from the display and control computer and the audio chip to the speaker of the headset with the first audio interface, while the fourth switch K3 switches the two audio signal outputs from the display and control computer and the audio chip to the speaker of the handset microphone with the second audio interface.

[0064] like Figure 7 As shown, the first audio interface has five terminals. When a headset is plugged into the first audio interface, the HP_MIC terminal is connected to the headset's microphone, the HP_LOUT_L terminal and the HP_LOUT_L terminal are connected to the two speakers of the left and right channels of the headset, respectively. Its INSERT_HP_DET terminal is connected to the GPIO7 pin of the processor and connected to the 3.3V power supply VCC through a 4.7K resistor R2. Its GND terminal is grounded. When no headset is plugged in, the INSERT_HP_DET terminal and the GND terminal are disconnected. Plugging in the headset will connect the INSERT_HP_DET terminal and the GND terminal.

[0065] like Figure 8As shown, the second audio interface has five terminals. When the handset microphone is plugged into the second audio interface, the HAND_MIC terminal is connected to the microphone of the handset microphone, the HAND_LOUT_L terminal and the HAND_LOUT_L terminal are connected to the two speakers of the left and right channels of the handset microphone, respectively. Its INSERT_HAND_DET terminal is connected to the GPIO8 pin of the processor and connected to the 3.3V power supply VCC through a 4.7K resistor R3. Its GND terminal is grounded. When the handset microphone is not plugged in, the INSERT_HAND_DET terminal and the GND terminal are disconnected. Plugging in the handset microphone will connect the INSERT_HAND_DET terminal and the GND terminal.

[0066] The voice terminal also includes a local microphone and a local speaker. The local microphone is connected to the LINEIN1R pin of the audio chip after passing through an operational amplifier, and the local speaker is connected to the DAC_X pin of the audio chip after passing through a power amplifier.

[0067] like Figure 6 As shown, the switch button is located on the front panel of the voice terminal. The switch button is a surface-mount soldered button and is connected to the motherboard through a 7-pin connector. One pin of the signal on the motherboard is connected to the GPIO1 pin of the CPU and is also connected to the power supply VCC through resistor R1. The other pin is connected to GND.

[0068] like Figure 3 As shown, the working principle of multi-voice scene switching in a voice terminal is as follows:

[0069] The CPU detects the presence of the first audio interface by checking the level of the GPIO7 signal. When the headset is inserted, the GPIO7 pin is connected to ground (GND) and is at a low level. The CPU detects that GPIO7 is at a low level, thus determining that the first audio interface has a headset inserted.

[0070] The CPU detects the presence of the second audio interface by checking the level of the GPIO8 signal. When the handset microphone is inserted, the GPIO8 pin is connected to ground (GND) and is at a low level. The CPU detects that GPIO8 is at a low level, thus determining that the second audio interface has a handset microphone inserted.

[0071] When either or both of the first and second audio interfaces have an in-position signal, the CPU defaults to setting GPIO2, GPIO3, GPIO4, and GPIO5 pins to high level. At this time, all four switches are in the first state. In the first state, the normally closed terminals of each switch are connected to the common terminal. If the headset is in position, the headset is connected to the display and control computer for use by the display and control computer. If the handset microphone is in position, the handset microphone is connected to the audio chip for use by the voice terminal.

[0072] The CPU determines whether the switch button is pressed by checking if GPIO1 is low. If GPIO1 is low, the CPU sets GPIO2, GPIO3, GPIO4, and GPIO5 to low. At this time, all four switches are in the second state. In the second state, the normally open terminals of each switch are connected to the common terminal, and the channels of the microphone and headset are switched. Otherwise, nothing changes.

[0073] Voice signals are collected by local microphones, headsets, and handset microphones, amplified by operational amplifiers, and converted from digital to analog by an audio CODEC chip. The signals are then transmitted to the CPU via a USB bus. The CPU encodes the voice signals into digital signals using the G.711 format and transmits them over the network to the voice terminal of another display / control computer for playback. Conversely, voice signals are collected by the microphone of the voice terminal on another display / control computer, transmitted over the network to the local display / control computer's voice terminal, decoded into digital signals using the G.711 format by the CPU, transmitted over the USB bus to the audio CODEC chip, and amplified by operational amplifiers before being played through local speakers, headset speakers, or handset microphone speakers.

[0074] The above description is merely an embodiment of the present invention and does not limit the scope of the patent. Any equivalent structure or equivalent transformation process utilizing the present invention and its accompanying drawings, or directly or indirectly applied to other related technical fields, are similarly included within the protection scope of the present invention.
