[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0031] With the rise of large-scale artificial intelligence (AI) models, voice input capabilities on smart terminals have become a significant trend and characteristic. In the future, with continuous technological advancements and expanding application scenarios, voice input capabilities on smart terminals will become more intelligent, convenient, and user-friendly, providing users with a superior experience. Correspondingly, to enhance voice input capabilities, using more microphones can achieve better voice input, enabling sensitive voice wake-up, higher-performance voice noise reduction, and other functions.

[0032] In related technologies, smartphones and other smart terminal devices typically use 2-3 microphones for input. However, this cannot meet the needs of large-scale AI models.

[0033] To address the aforementioned technical problems, the inventors of this disclosure have discovered that the limitation on smart terminals to supporting more microphones stems from the fact that current audio processing chips can only support a maximum of a certain number (e.g., 5) of analog microphone interfaces, and one of these interfaces must also support analog headphones with a USB Type-C interface. Developing a new chip would be prohibitively expensive. Therefore, the inventors further discovered that a switching switch can be used to connect more microphones; for example, a switch can be added to switch between analog headphones and newly added microphones. Based on this, embodiments of this disclosure provide a microphone control system.

[0034] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0035] Figure 1 Schematic diagram of the microphone control system provided in the embodiments of this disclosure Figure 1 .like Figure 1 As shown, the system includes: a first switching switch 102 and an audio processor.

[0036] The audio processor includes a first microphone 103 interface; the first switch 102 includes a first selection terminal, a second selection terminal, and a common terminal.

[0037] The first selection terminal of the first switch 102 is used to connect to the first microphone 103; the second selection terminal of the first switch 102 is used to connect to the second microphone 104; and the common terminal of the first switch 102 is connected to the first microphone 103 interface of the audio processor.

[0038] The first microphone 103 is used to receive the first audio signal.

[0039] The second microphone 104 is used to receive the second audio signal.

[0040] The first switch 102 is used to receive a first switching control signal. Under the control of the first switching control signal, the first selection terminal of the first switch 102 is connected to the common terminal, and the first audio signal is sent to the audio processor.

[0041] The first switch 102 is also used to receive a second switching control signal, and under the control of the second switching control signal, connect the second selection terminal of the first switch 102 to the common terminal, and send the second audio signal to the audio processor.

[0042] The first switching control signal and the second switching control signal are different enable signals, meaning that at most one of the first selection terminal and the second selection terminal of the first switching switch 102 can be connected to the common terminal at any given time. The operating state of the first switching switch 102 can include the first path being on and the second path being off, i.e., the first selection terminal being connected to the common terminal and the second selection terminal being off; it can also include the second path being on and the first path being off, i.e., the first selection terminal being off and the second selection terminal being connected to the common terminal; or it can also include both paths being off, i.e., the first selection terminal being off and the second selection terminal being off.

[0043] In practical operation, assuming the system is applied to a terminal device, after the terminal device is started, one of the channels of the first switch 102 is turned on by default, for example, the second selection terminal and the common terminal are connected, that is, the second microphone 104 is connected to the first microphone 103 interface of the audio processor by default. When the terminal device detects that the current usage scenario meets the preset conditions, the second switch 105 receives the first switching control signal, which causes the first selection terminal to connect to the common terminal, that is, the first microphone 103 is connected to the first microphone 103 interface of the audio processor.

[0044] In this embodiment of the disclosure, the first switching switch 102 is an analog switch, which can be a transistor switch, such as a metal-oxide-semiconductor field-effect transistor (MOSFET) switch, a complementary metal-oxide-semiconductor (CMOS) switch, etc.

[0045] In this embodiment of the disclosure, the audio processor may include multiple microphone interfaces. Exemplarily, the audio processor may include a codec analog core and a USB subsystem. The codec analog core is used for analog signal processing such as amplification, filtering, and mixing. The USB subsystem is used to manage USB interface communication. It includes physical layer, link layer, and transport layer, and is used to ensure that data can be transmitted securely and efficiently through the USB interface. The USB subsystem supports USB Type-C digital communication, analog audio, DisplayPort auxiliary control, and battery charger communication.

[0046] As can be seen from the above description, the microphone control system provided in this embodiment of the present disclosure expands the microphone interface and is compatible with the access of more microphones when the number of microphone channels of the audio processor is limited by setting a switching switch.

[0047] In one embodiment of this disclosure, the audio processor further includes a plurality of third microphone interfaces; each third microphone interface is configured to be directly connected to a single microphone, or to be connected to a plurality of microphones via a switch; the audio processor is further configured to receive, for each third microphone interface, a sixth audio signal transmitted by a microphone connected to the third microphone interface; the audio processor is further configured to process at least one of the sixth audio signals and a first audio signal or a second audio signal received by the audio processor via the first switch.

[0048] In this embodiment of the disclosure, the number of microphones supported by the audio processor is greater than the number of microphone interfaces of the audio processor.

[0049] Specifically, the audio processor includes multiple microphone interfaces, but the total number of microphone interfaces is limited, for example, five or six. However, the number of microphones required by the system is greater than the number of microphone interfaces that the audio processor can provide. Therefore, by setting a switch connected to the microphone interface, the number of microphones that the microphone interface can connect to can be expanded. For example, originally a single microphone interface could only support one microphone connection, but by setting a switch, multiple microphones can be connected to the same microphone interface through the switch, so that a single microphone interface can support multiple microphones connected in different situations. Although only one microphone can be selected to connect to the corresponding microphone interface at a time through the switch, it can effectively deal with the waste of microphone interfaces due to microphone failure, or the need to select different microphones in different scenarios (for example, if there are 10 microphones, depending on the usage scenario, only the 5 microphones located at the top of the phone can be used, and by controlling the switch, only these 5 microphones can be connected to the audio processor).

[0050] For example, taking a mobile phone as the terminal device, the phone's audio processor has 5 interfaces. Five microphones are distributed in preset locations on the phone. Four of these microphones are directly connected to the four interfaces of the audio processor, one microphone is connected to the audio processor via the first selection terminal of switch 1, and the second selection terminal of switch 1 is connected to the headphones. When no headphones are plugged in, switch 1 activates the corresponding microphone, and the audio processor processes the audio from all five microphones together, resulting in better noise reduction or ambient sound acquisition. When headphones are plugged in, switch 1 activates the headphones, and the audio processor processes the audio received from the headphones' microphone along with the audio from the other four microphones, resulting in better acquisition of human voices and ambient sounds from the phone's microphones, all processed together.

[0051] In one embodiment of this disclosure, based on the above embodiments, for example in Figure 1 Based on the embodiment shown, the first microphone 103 is a microphone installed in an external device; the second microphone 104 is a microphone installed on a terminal device.

[0052] In this embodiment of the disclosure, the external device can be a speaker, an audio recording device, or the like.

[0053] For example, taking a Type-C headset as the external device, such as Figure 2 As shown, the audio processor includes multiple analog-to-digital converters (ADCs) ADC1-ADCx, where x is a positive integer greater than 1. The audio processor can provide five analog interfaces, namely AMIC1, AMIC2, and up to AMIC5. That is, in related technologies, these five analog interfaces can only support a maximum of four microphones and one Type-C headset. However, the microphone control system provided in this embodiment can expand the interface by setting a first switching switch 102, allowing for the connection of a Type-C headset and supporting the connection of one microphone. Specifically, AMIC2 is connected to the first microphone 103 and the second microphone 104 via the first switching switch 102.

[0054] In one embodiment of this disclosure, the system further includes a second switching switch 105.

[0055] The audio processor also includes a second microphone 104 interface; the second switch 105 includes a first selection terminal, a second selection terminal, and a common terminal.

[0056] The first selection terminal of the second switch 105 is used to connect to the third microphone 106; the second selection terminal of the second switch 105 is used to connect to the fourth microphone 107; and the common terminal of the second switch 105 is connected to the second microphone 104 interface of the audio processor.

[0057] The third microphone 106 is used to receive the third audio signal.

[0058] The fourth microphone 107 is used to receive the fourth audio signal.

[0059] The second switch 105 is used to receive the third switching control signal. Under the control of the third switching control signal, the first selection terminal of the second switch 105 is connected to the common terminal, and the third audio signal is sent to the audio processor.

[0060] The second switch 105 is also used to receive the fourth switching control signal. Under the control of the fourth switching control signal, the second selection terminal of the second switch 105 is connected to the common terminal, and the fourth audio signal is sent to the audio processor.

[0061] Specifically, an audio processor can have multiple microphone interfaces, and therefore, correspondingly, multiple toggle switches can be used to support different numbers of microphones. For example, assuming the toggle switch has two channels, each toggle switch can support one more microphone.

[0062] For example, taking a Type-C headset as the external device, such as Figure 3 As shown, the AMIC2 interface of the audio processor can be connected to the first switch 102 to connect the first microphone 103 and the second microphone 104, i.e., MIC2 and a USB Type-C headset. The AMIC2 interface of the audio processor can be connected to the second switch 105 to connect the third microphone 106 and the fourth microphone 107, i.e., MIC5 and MIC6.

[0063] In one embodiment of this disclosure, the first switching switch 102 further includes a third selection terminal.

[0064] The third selection terminal of the first switch 102 is used to connect to the fifth microphone.

[0065] The fifth microphone is used to receive the fifth audio signal.

[0066] The first switching switch 102 is also used to receive the fifth switching control signal. Under the control of the fifth switching control signal, the third selector terminal of the first switching switch 102 is connected to the common terminal, and the fifth audio signal is sent to the audio processor.

[0067] Specifically, in order to support a larger number of microphones, a switch with more channels can be used, such as a switch that supports three channels. Based on this, for each additional switch, two more microphones can be supported.

[0068] In one embodiment of this disclosure, to achieve automatic switch control, an insertion detection module can be configured to detect whether an external device is inserted, and control the switch to open or close based on the detection result. Specifically, the system further includes: an interface, an insertion detection module 108, and a controller 100; the interface is connected to the first selection terminal of the first switch 102 and the insertion detection module 108; the insertion detection module 108 is connected to the controller 100; the controller 100 is connected to the first switch 102; the insertion detection module 108 is used to generate a peripheral device insertion indication signal if an external device is detected inserted into the interface, and send the peripheral device insertion indication signal to the controller 100; the controller 100 is used to generate a first switching control signal based on the peripheral device insertion indication signal, and send the first switching control signal to the first switch 102.

[0069] In this embodiment of the disclosure, the external device can be a headset, and the interface can be a Type-C or a 3.5mm headphone jack.

[0070] In this embodiment of the disclosure, the insertion detection module 108 can be set as an independent module or integrated into other modules, such as an audio processor.

[0071] In one possible implementation, taking headphones as an external device as an example, such as... Figure 4 As shown, the insertion detection module 108 detects whether the headphone jack to which the first microphone 103 belongs is plugged in, and then generates a headphone insertion indication signal and sends it to the controller 100. The controller 100 then generates a first switching control signal based on this headphone insertion indication signal and sends it to the first switching switch 102. This causes the first switching switch 102 to connect the first microphone 103 to the first microphone 103 interface of the audio processor, enabling the headphones to function normally. Correspondingly, the connection between the second microphone 104 and the first microphone 103 interface is disconnected via the first switching switch 102.

[0072] In another possible implementation, the insertion detection module 108 can be integrated into the audio processor, so that the headphone insertion indication signal output by the insertion detection module 108 can be sent to the controller 100 through the audio processor.

[0073] For example, such as Figure 5As shown, the insertion detection module 108 is integrated into the audio processor. The controller 100 is connected to the audio processor via an audio interface and a control interface. The controller 100 is connected to the control terminals of the first switch 102 and the second switch 105 via general purpose input / output ports (GPIO) to control the switches for path switching. The first switch 102 selects either the first microphone 103 or the second microphone 104 (MIC2 or USB Type-C headset), and the second switch 105 selects either the third microphone 106 or the fourth microphone 107 (MIC5 or MIC6). The control interface can typically be an I2C interface, an SPI interface, or an SPMI interface.

[0074] In one embodiment of this disclosure, the insertion detection module 108 is further configured to generate a peripheral device unplugging indication signal if it detects that an external device has been unplugged from the interface, and send the peripheral device unplugging indication signal to the controller 100; the controller 100 is further configured to generate a second switching control signal based on the peripheral device unplugging indication signal, and send the second switching control signal to the first switching switch 102.

[0075] Specifically, one selector of the first switch connects to the microphone in the headset, and the other selector connects to the microphone on the terminal device. By default, the first switch can be connected to the microphone on the terminal device. When an external device such as a headset is plugged in, the first switch can be connected to the microphone in the headset, disconnecting it from the microphone on the terminal device. When the external device is unplugged, the first switch can be reconnected to the microphone on the terminal device.

[0076] For example, such as Figure 5 As shown, by default, the first switch 102 is set to connect the audio processor to the microphone MIC2. When a USB Type-C headset is plugged in, the audio processor senses the plugging operation through the plugging detection module 108 and then notifies the controller 100 through the control interface. The controller 100 sends a control signal via GPIO to switch the first switch 102, connecting the audio processor to the Type-C headset. When the USB Type-C headset is unplugged, the audio processor senses the unplugging operation through the plugging detection module 108 and then notifies the controller 100 through the control interface. The controller 100 again sends a control signal via GPIO to switch the first switch 102, connecting the audio processor to the microphone MIC2.

[0077] In one embodiment of this disclosure, the first microphone 103 and the second microphone 104 are both microphones installed on the terminal device.

[0078] In one embodiment of this disclosure, the system includes: a controller 100; the controller 100 is connected to a first switching switch 102; the controller 100 is configured to determine the current usage scenario, generate a first switching control signal based on the current usage scenario, and send the first switching control signal to the first switching switch 102, or generate a second switching control signal based on the current usage scenario and send the second switching control signal to the first switching switch 102.

[0079] Specifically, the usage scenario can be determined based on information from the upper-layer application and / or the access status of each microphone, and then the switching switch can be switched based on the usage scenario. For example, when both selection terminals of the first switching switch 102 are connected to a single microphone set on the terminal device, if a user touch operation on the answer control in the call interface is detected, the usage scenario of the terminal device is determined to be answering a phone call based on the answer control signal generated in response to the touch operation. In this scenario, a control signal (first switching control signal or second switching control signal) can be generated to control the switching switch to select the microphone (first microphone or second microphone) that is more conducive to enhancing the answering effect and connect it to the audio processor to adapt to the current call scenario.

[0080] Taking a mobile phone as an example, usage scenarios can include placing the phone screen up, placing the phone screen down, the phone being picked up, and the microphone being blocked.

[0081] In this embodiment of the disclosure, there are multiple ways to determine the current usage scenario of the terminal device.

[0082] In one possible implementation, scene identification of whether the microphone is blocked can be based on ambient noise. Specifically, the controller 100 is connected to an audio processor; the first audio signal includes ambient noise; the audio processor is also used to detect the ambient noise and send the detection result to the controller 100; the controller 100 is also used to determine the current usage scene based on the detection result.

[0083] Specifically, when a microphone is blocked, the ambient noise it can detect will decrease. Therefore, a threshold can be set; when the ambient noise detected by the microphone is below this threshold, it indicates that the microphone is blocked. Use of that microphone needs to be paused, and the control switch should be used to switch to another microphone connected to the switch.

[0084] In another possible implementation, the system also includes a sensor; the controller 100 is connected to the sensor; the controller 100 is also used to acquire the sensing data collected by the sensor and determine the current usage scenario based on the sensing data.

[0085] Specifically, sensors can include gyroscopes, accelerometers, and proximity sensors. Taking a mobile phone as an example, during the phone-holding detection process, the accelerometer and gyroscope in the phone can detect the phone's movement and changes in orientation. When the phone suddenly moves from a stationary state, these sensors can trigger an event to notify the system that the phone has been picked up. Proximity sensors can detect whether the phone is close to the user's ear or face, which typically occurs when making or receiving calls. While this sensor is primarily used to automatically turn off the screen to prevent accidental touches, it can also be used to assist in detecting whether the phone has been picked up.

[0086] In another possible implementation, the phone's position can be determined by the strength of the signal received by the antenna. When the antenna signal is lower than a preset strength, it indicates that the antenna may be blocked. Therefore, nearby microphones can be paused and the switch can be used to switch to other unblocked microphones.

[0087] In one embodiment of this disclosure, the microphone can be located on the side of the terminal device's screen, or on the opposite side of the screen, or on the side, or on the top or bottom side of the screen. The specific configuration can be determined according to actual needs, and this disclosure does not limit the specific configuration.

[0088] The following combination Figure 6 The diagram shown illustrates the structure of the microphone control system and provides examples of the connections between the modules.

[0089] like Figure 6 As shown, the first microphone 103 of the audio processor is connected to the first switch 102 via resistors R8 and R9. The first switch 102 is connected to the second microphone 104 via resistors R1, R2, and R3, capacitors C2 and C3, and Zener diodes D2 and D3. The power supply terminal VDD of the second microphone 104 is connected to BIAS2 via C1 and D1. The USB Type-C headset includes the first microphone 103 and is connected to the audio processor via switching transistors M1 and M2, and resistors R4 and R5. The control inputs of the switching transistors are CTL1 and CTL2. The audio processor is connected to the first switch 102 via inductors L1 and L2, resistors R6 and R7, and capacitors C4 and C5, and is also connected to voltage BIAS1 via R6 and R7. The USB Type-C headset can be connected to the first switch 102 via a bridge connection. BIAS1 and BIAS2 can be generated by the audio processor, as can CTL1 and CTL2.

[0090] By employing the above-described connection method, the embodiments disclosed herein can achieve more stable signals and have lower noise.

[0091] This disclosure also provides a terminal device, including a microphone control system as described in the above embodiments.
