[0059] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0060] Far-field voice, as a voice search that integrates artificial intelligence (AI), is widely used in voice interaction technology in smart interactive devices. For example, smart interactive devices can be smart home appliances such as smart TVs and smart speakers. Of course, they can also be other smart devices with human-computer interaction functions, which are not limited in the embodiments of the present disclosure. At present, far-field voice can achieve voice control at a distance of 5 meters, that is, users can remotely operate smart interactive devices by speaking voice commands at a long distance, eliminating the tedious operation of traditional remote control button control. However, in some scenarios, considering that users may not want to use voice interaction, the far-field voice interaction function can be turned off. In addition, when the smart interactive device is not turned on, the far-field voice function cannot be realized. At this time, traditional remote control devices are indispensable, and the most common remote control devices are infrared remote controls. Based on this, how to combine far-field voice and infrared reception on a small board to reduce costs has become a major problem that needs to be solved urgently.

[0061] The embodiments of the present disclosure provide an interactive integrated circuit for use in an intelligent interactive device with a voice interaction function, which can realize a two-in-one design of far-field voice and infrared reception.

[0062] FIG1 shows a schematic block diagram of an interactive integrated circuit provided by an embodiment of the present disclosure. As shown in FIG1 , the interactive integrated circuit includes:

[0063] Circuit board 01. And, signal detection module 02, voice interaction module 03 and status indication module 04 integrated on circuit board 01.

[0064] The signal detection module 02 can be used to detect the switch signal to control the switch state of the intelligent interactive device.

[0065] Optionally, the switch signal here can be the infrared signal recorded in the above embodiment, and the infrared signal can be emitted by a control device similar to a remote control. When the signal detection module 02 detects the infrared signal, it can control the intelligent interactive device (such as a smart TV) to turn on or off, which can also be called power on or off.

[0066] The voice interaction module 03 can be used to collect voice signals when the intelligent interactive device is turned on and the voice interaction function is turned on, so as to control the intelligent interactive device to perform the operation indicated by the voice signal.

[0067] Optionally, the intelligent interactive device or remote control may be provided with a switch to turn the voice interaction function on or off. When the intelligent interactive device is turned on and the voice interaction function is enabled at the same time, the voice interaction module 03 can reliably receive the voice signal sent by the user to instruct the intelligent interactive device to perform the operation indicated by the voice signal. For example, the voice signal may be "Play the first episode of TV series xx." In this case, the intelligent interactive device can directly play the first episode of TV series xx based on the voice signal to complete the voice response. Of course, the voice signal here can be a far-field voice signal sent by the user at a longer distance.

[0068] The status indication module 04 can be used to send an indication signal in response to a received control instruction to indicate the working status of the intelligent interactive device and the working status of the voice interaction module 03.

[0069] Optionally, for the intelligent interactive device, the control instruction received by the status indication module 04 may be a power-on instruction or a power-off instruction. Furthermore, in order to distinguish between a power-on instruction and a power-off instruction, the signal potentials of the power-on instruction and the power-off instruction received here may be different, such as a high-potential signal may indicate a power-on instruction, and a low-potential signal may indicate a power-off instruction, and high potential and low potential are relative. Upon receiving the power-on instruction, the status indication module 04 may issue an indication signal to indicate that the intelligent interactive device is turned on; upon receiving the power-off instruction, it may issue another indication signal to indicate that the intelligent interactive device is turned off. The indication signal here may be a light signal. Furthermore, in order to distinguish between the on and off states of the intelligent interactive device, the light colors of one indication signal and another indication signal may be different. For example, red may be used to indicate that the intelligent interactive device is turned off; blue may be used to indicate that the intelligent interactive device is turned on.

[0070] Optionally, for the voice interaction module 03, the control instruction received by the status indication module 04 may be an on instruction to turn on the voice interaction function, an off instruction to turn off the voice interaction function, or a voice recognition instruction indicating that a voice signal is being recognized. Furthermore, to distinguish between different instructions, the signal potentials of the received instructions may be different. Upon receiving an on instruction, the status indication module 04 may issue one indication signal to indicate that the voice interaction function is on; upon receiving an off instruction, another indication signal to indicate that the voice interaction function is off; and upon receiving a voice recognition instruction, yet another indication signal to indicate that a voice signal is being recognized. Similarly, the indication signal may be a light signal. Furthermore, to distinguish between the on, off, and recognition states of the voice interaction function, the light colors / states of one indication signal, another indication signal, and yet another indication signal may be different. For example, off light may indicate that the voice interaction function is on; orange light may indicate that the voice interaction function is off; and white light may indicate that a voice signal is being recognized.

[0071] Of course, the above instruction types, working states, and indication signals are all schematic illustrations. The embodiments of the present disclosure do not limit this. Optionally, the intelligent interactive device may further include a main controller (e.g., a master control chip), and the above control instructions may be issued by the main controller.

[0072] Furthermore, along a target direction X1 parallel to the bearing surface of the circuit board 01 , the signal detection module 02 , the voice interaction module 03 and the status indication module 04 may be arranged at intervals on the circuit board 01 .

[0073] Optionally, the circuit board 01 may be rectangular as shown in FIG1 , and the target direction X1 may refer to the length direction of the circuit board 01. Of course, the shape and direction here are also schematic illustrations.

[0074] In summary, the embodiments of the present disclosure provide an interactive integrated circuit for use in intelligent interactive devices. The interactive integrated circuit includes a circuit board, and the following modules integrated on the circuit board: a signal detection module for detecting switch signals to control the switch state of the intelligent interactive device; a voice interaction module for collecting voice signals to control the intelligent interactive device to perform the operation indicated by the voice signal to achieve voice interaction; and a status indication module for issuing an indication signal to indicate the working status of the intelligent interactive device and the voice interaction module therein. Moreover, the multiple modules can be arranged at intervals along one direction on the circuit board. In this way, a design in which modules performing different functions are integrated on one circuit board is realized, which can be beneficial to the design of intelligent interactive devices and greatly reduce the design cost.

[0075] Optionally, as described in the above embodiment, the voice signal described in the embodiment of the present disclosure may include a far-field voice signal, i.e., a voice signal emitted by a user at a relatively long distance from the intelligent interactive device. Accordingly, the voice interaction module 03 may include a far-field voice interaction module. Furthermore, referring to FIG2 , which shows a schematic block diagram of a voice interaction module provided in an embodiment of the present disclosure, the far-field voice interaction module may include a power supply component 031 and a voice collection component 032.

[0076] The power supply component 031 can be coupled to the reference power supply terminal DVDD_3V3 and the power supply terminal VDD_MIC, respectively. The power supply component 031 can be configured to transmit a power supply signal to the power supply terminal VDD_MIC based on a reference power supply signal provided by the reference power supply terminal DVDD_3V3. The power supply signal can have a potential less than or equal to that of the reference power supply signal.

[0077] For example, in the disclosed embodiment, the potential of the reference power signal can be 3.3 volts (V); the potential of the power supply signal can be 3.3V or 1.8V. Because a power supply signal with a higher potential has a higher noise floor than a power supply signal with a lower potential, a 1.8V power supply signal is often used. Of course, the potentials here are for illustrative purposes only.

[0078] The voice collection component 032 can be coupled to the power supply terminal VDD_MIC and can be used to collect far-field voice signals under the control of the power supply signal.

[0079] Furthermore, referring to FIG3 , which is a schematic block diagram of another interactive integrated circuit provided by an embodiment of the present disclosure, it can be seen that the power supply component 031 and the voice collection component 032 can be located on opposite sides of the circuit board 01, respectively, and the voice collection component 032, the signal detection module 02, and the status indication module 04 can be located on the same side of the circuit board 01. The two opposite sides here may refer to the front and back sides of the circuit board 01. Of course, to facilitate coupling of the power supply component 031 and the voice collection component 032 via the power supply terminal VDD_MIC, the orthographic projections of the power supply component 031 and the voice collection component 032 on the circuit board 01 may overlap, as shown in FIG3 .

[0080] It should be noted that FIG1 may refer to a front view of the interactive integrated circuit; FIG3 may refer to a side view of the interactive integrated circuit, and may also be considered as a cross-sectional view.

[0081] Optionally, based on Figure 3, Figure 4 shows a schematic circuit diagram of a voice interaction module 03 provided by an embodiment of the present disclosure. As shown in Figure 4, the voice collection component 032 recorded in the embodiment of the present disclosure may include: two voice collection units 0321, belonging to a dual voice collection structure.

[0082] Optionally, each voice acquisition unit 0321 can be a common microphone (MIC). Furthermore, each voice acquisition unit 0321 can include a voice acquisition chip DMIC. The voice acquisition chip DMIC can have a data pin DATA, a select pin SEL, a pull-up pin VDD, a pull-down pin GND, and a clock pin CLK.

[0083] Among them, the data pin DATA of the voice acquisition chip DMIC can be coupled to the data terminal DM_SDA providing the data signal through the first resistor R1. The selection pin SEL of the voice acquisition chip DMIC can be coupled to the power supply terminal VDD_MIC and the ground terminal respectively through the second resistor R2 and the third resistor R3 connected in parallel. The pull-down pin GND of the voice acquisition chip DMIC can be coupled to the ground terminal. The pull-up pin VDD of the voice acquisition chip DMIC can be coupled to the power supply terminal VDD_MIC. The clock pin CLK of the voice acquisition chip DMIC can be coupled to the clock terminal DM_SCL providing the clock signal through the fourth resistor R4. And a first capacitor C1 and a second capacitor C2 can be connected in parallel between the power supply terminal VDD_MIC and the ground terminal. The setting of the resistors and capacitors can ensure better signal quality. The same applies to the following embodiments and will not be repeated one by one.

[0084] For the purpose of distinction, the two voice acquisition units 0321 are respectively identified as 0321-1 and 0321-2 in FIG4 , and the voice acquisition chip DMIC included in the voice acquisition unit 0321-1 is identified as DMIC1 , and the voice acquisition chip DMIC included in the voice acquisition unit 0321-2 is identified as DMIC2 .

[0085] Alternatively, referring to FIG. 4 , the data pin DATA of the voice acquisition chip DMIC may be the first pin 1; the select pin SEL of the voice acquisition chip DMIC may be the second pin 2; the pull-down pin GND of the voice acquisition chip DMIC may be the third pin 3; the clock pin CLK of the voice acquisition chip DMIC may be the fourth pin 4; and the pull-up pin VDD of the voice acquisition chip DMIC may be the fifth pin 5. This is, of course, merely an illustrative example.

[0086] Optionally, for voice collection unit 0321-1, the third resistor R3 coupled to the ground terminal can be a reserved component (indicated by a dotted line, and the same applies below, so it will not be repeated here). That is, the third resistor R3 may or may not be provided. For voice collection unit 0321-2, the second resistor R2 coupled to the power supply terminal VDD_MIC can be a reserved component. That is, the second resistor R2 may or may not be provided. Accordingly, voice collection unit 0321-1 can also be referred to as a high-level voice collection unit, and voice collection unit 0321-2 can also be referred to as a low-level voice collection unit.

[0087] In addition, referring to the schematic block diagram of another interactive integrated circuit provided by an embodiment of the present disclosure shown in Figure 5, it can be seen that the two voice collection units 0321-1 and 0321-2 can be located on both sides of the status indication module 04 respectively to collect far-field voice signals from different directions, thereby ensuring better reliability of collecting far-field voice signals.

[0088] Optionally, referring to Figure 5 , the two voice collection units 0321-1 and 0321-2 can be symmetrically arranged on either side of the status indicator module 04. That is, in the target direction X1, the spacing between each voice collection unit 0321 and the status indicator module 04 can be equal. This further ensures greater reliability in collecting far-field voice signals.

[0089] Optionally, as an optional implementation, the potential of the power supply signal is equal to the potential of the reference power supply signal. For example, both are 3.3V as described in the above embodiment. On this basis, referring to FIG. 4 , it can be seen that the power supply component 031 described in the embodiment of the present disclosure may include a fifth resistor R5.

[0090] One end of the fifth resistor R5 can be coupled to the reference power supply terminal DVDD_3V3, and the other end of the fifth resistor R5 can be coupled to the power supply terminal VDD_MIC. The fifth resistor R5 can isolate the reference power supply terminal DVDD_3V3 and the power supply terminal VDD_MIC.

[0091] Optionally, as another optional implementation method: the potential of the power supply signal may be less than the potential of the reference power supply signal. For example, the potential of the power supply signal may be 1.8V as described in the above embodiment; the potential of the reference power supply signal may be 3.3V as described in the above embodiment. On this basis, referring to FIG4 , it can be seen that the power supply component 031 described in the embodiment of the present disclosure may include: a potential conversion chip U1 for converting the reference power supply signal into a power supply signal. The potential conversion chip U1 may have an input pin IN, an output pin OUT, an enable pin EN, and a power pin GND / EPAD.

[0092] The input pin IN of the potential conversion chip U1 can be coupled to the reference power supply terminal DVDD_3V3. The output pin OUT of the potential conversion chip U1 can be coupled to the power supply terminal VDD_MIC. The enable pin EN of the potential conversion chip U1 can be coupled to the reference power supply terminal DVDD_3V3 via a sixth resistor R6 and can be coupled to ground via a third capacitor C3. The power pin GND / EPAD of the potential conversion chip U1 can be coupled to ground. The reference power supply terminal DVDD_3V3 can also be coupled to ground via a fourth capacitor C4, and the power supply terminal VDD_MIC can also be coupled to ground via a fifth capacitor C5.

[0093] Alternatively, referring to FIG. 4 , it can be seen that the output pin OUT of the potential conversion chip U1 can be the first pin 1; the power pins GND / EPAD of the potential conversion chip U1 can be the second pin 2 and the fifth pin 5, respectively; the enable pin EN of the potential conversion chip U1 can be the third pin 3; and the input pin IN of the potential conversion chip U1 can be the fourth pin 4. Of course, this is merely a schematic illustration.

[0094] Optionally, the sixth resistor R6, the third capacitor C3, the fourth capacitor C4 and the fifth capacitor C5 can all be reserved components, that is, the corresponding positions can be optionally provided with or without the above resistors and capacitors.

[0095] It should be noted that, for the purpose of distinction, in FIG4 , the power supply component 031 in one optional implementation is identified as 031A; and the power supply component 031 in another optional implementation is identified as 031B.

[0096] Based on the schematic circuit diagram of the voice interaction module 03 shown in FIG4 , it can be seen that the voice interaction module 03 described in the embodiment of the present disclosure can be powered by a 3.3V or 1.8V power supply signal. The two voice acquisition units (i.e., two microphones) serve as the main sound pickup devices, converting the user's voice signal into a digital signal and transmitting it to the system-on-a-chip (SOC) in the intelligent interactive device to control the intelligent interactive device to perform corresponding actions.

[0097] Optionally, Figure 6 shows a schematic block diagram of another interactive integrated circuit provided by an embodiment of the present disclosure. As shown in Figure 6 , the state indication module 04 in the interactive integrated circuit may include: a first indication unit 041 and a second indication unit 042 .

[0098] The indication signal sent by the first indication unit 041 may be used to indicate the working state of the voice interaction module 03. The indication signal sent by the second indication unit 041 may be used to indicate the working state of the intelligent interaction device.

[0099] Furthermore, the first indication unit 041 may be located between the second indication unit 042 and the voice interaction module 03 , and may be located on a side of the second indication unit 042 close to the signal detection module 02 .

[0100] Optionally, as described in the above embodiment, the indication signal emitted by the first indication unit 041 may include a light signal. Based on this, referring to FIG7 , which shows a schematic circuit diagram of a first indication unit 041 provided in an embodiment of the present disclosure, it can be seen that the first indication unit 041 may include a control switch 0411 and a first indicator light group 0412. The first indicator light group 0412 may include a plurality of first indicator lights L1 connected in series.

[0101] The control terminal of the control switch 0411 can be coupled to the indicator light control terminal DM_L that provides control instructions via a seventh resistor R7. The input terminal of the control switch 0411 can be coupled to the indicator light power supply terminal L_5V via an eighth resistor R8, and can be coupled to multiple first indicator lights L1 connected in series via a ninth resistor R9. The output terminal of the control switch 0411 can be coupled to ground. A tenth resistor R10 can be connected in series between the input terminal and the control terminal of the control switch 0411, and a sixth capacitor C6 can be connected in series between the output terminal and the control terminal of the control switch 0411. The indicator light power supply signal provided by the indicator light power supply terminal L_5V can be used to control the lighting state of the first indicator light L1 and is the power supply voltage of the first indicator light L1.

[0102] Optionally, the tenth resistor R10 and the sixth capacitor C6 may be reserved components, that is, the resistor and capacitor may be provided or not provided at the corresponding positions.

[0103] Optionally, the potential of the indicator light power supply signal provided by the indicator light power supply terminal L_5V may be 5 V. Of course, this is only a schematic illustration.

[0104] Optionally, the control switch 0411 can be the switching transistor Q1 shown in Figure 7 . Accordingly, the control terminal of the control switch 0411 can be the gate of the switching transistor Q1; the input terminal of the control switch 0411 can be the drain of the switching transistor Q1; and the output terminal of the control switch 0411 can be the source of the switching transistor Q1. Of course, the source and drain can be interchanged here. The control instructions provided by the indicator light control terminal DM_L can control the lighting or non-lighting of the first indicator light L1 by turning the switching transistor Q1 on and off.

[0105] Optionally, the switching transistor Q1 can be an N-type metal-oxide-semiconductor (MOS) field-effect transistor, or NMOS for short. Of course, it can also be a PMOS. For an NMOS transistor, when its gate receives a high-voltage signal, the NMOS transistor can be turned on; conversely, when its gate receives a low-voltage signal, the NMOS transistor can be turned off. Conversely, for a PMOS transistor, when its gate receives a low-voltage signal, the PMOS transistor can be turned on; conversely, when its gate receives a high-voltage signal, the PMOS transistor can be turned off. Of course, the transistor types here are only schematic illustrations.

[0106] Optionally, referring to FIG. 7 , each first indicator light L1 may include an indicator light chip U2. The indicator light chip U2 may have an input pin DIN, an output pin DOUT, a pull-down pin VSS, and a pull-up pin VDD. The plurality of first indicator lights L1 connected in series may be coupled to the input terminal of the control switch 0411 (i.e., the drain of the switching transistor Q1) via the input pin of the indicator light chip U2 of one of the first indicator lights L1, and each first indicator light L1 may be connected in series via the input pin DIN and the output pin OUT of the indicator light chip U2. An eleventh resistor R11 may be connected in series between the input pin DIN and the output pin OUT of the indicator light chip U2. The pull-up pin VDD of the indicator light chip U2 may be coupled to the indicator light power supply terminal L_5V. The pull-down pin VSS of the indicator light chip U2 may be coupled to ground. The pull-up pin VDD of the indicator light chip U2 is also coupled to ground via a seventh capacitor C7.

[0107] Alternatively, referring to FIG. 7 , it can be seen that the pull-up pin VDD of the indicator chip U2 can be the first pin 1; the output pin DOUT of the indicator chip U2 can be the second pin 2; the pull-down pin VSS of the indicator chip U2 can be the third pin 3; and the input pin DIN of the indicator chip U2 can be the fourth pin 4. Of course, this is merely a schematic illustration.

[0108] For example, in the schematic circuit diagram shown in FIG7 , the first indicator light group 0412 includes: four first indicator lights L1 connected in series, and the first indicator lights L1 are light-emitting diodes (LEDs, i.e., RGB LEDs) that can emit red (Red, R), green (Green, G), and blue (Blue, B) light. In addition, for distinction, the four first indicator lights L1 are respectively identified as L1-1, L1-2, L1-3, and L1-4 in FIG7 .

[0109] Based on the structure shown in Figure 7, as described in the above embodiment, when the voice interaction function is in the off state, it can be indicated by controlling the four RGB LEDs to be orange; when the voice interaction function is in the on state, it can be indicated by controlling the four RGB LEDs to be off; when a voice signal is recognized, it can be indicated by controlling the four RGB LEDs to be white. Here, the color state can be controlled by the control signal provided by the indicator light control terminal DM_L.

[0110] Optionally, Figure 8 shows a schematic block diagram of another interactive integrated circuit provided by an embodiment of the present disclosure. As shown in Figure 8, along the target direction X1, multiple first indicator lights L1 connected in series (e.g., the four first indicator lights L1-1, L1-2, L1-3, and L1-4 shown in Figure 7) can be arranged at intervals.

[0111] Furthermore, among the plurality of first indicator lights L1 connected in series, the distance between any two adjacent first indicator lights L1 can be equal to the distance threshold. That is, the distance between any two adjacent first indicator lights L1 can be equal. In this way, a better display effect can be ensured.

[0112] Optionally, as described in the above embodiment, the indication signal emitted by the second indication unit 042 may also include a light signal. Based on this, referring to FIG9 , which shows a schematic circuit diagram of a second indication unit 042 provided in an embodiment of the present disclosure, it can be seen that the second indication unit 042 may include a second indicator light group 0421. The second indicator light group 0421 may include a plurality of second indicator lights L2 connected in parallel.

[0113] The input terminal of each second indicator light L2 can be coupled to the indicator light control terminal L_X providing the control command via the twelfth resistor R12. The output terminal of each second indicator light L2 can be coupled to the ground terminal. The input terminals of multiple second indicator lights L2 connected in parallel can also be coupled to the ground terminal via different eighth capacitors C8.

[0114] Optionally, the eighth capacitor C8 may be a reserved component, that is, the eighth capacitor C8 may be provided or not provided at the corresponding position.

[0115] For example, in the schematic circuit diagram shown in FIG9 , second indicator light group 0412 includes two second indicator lights L2 connected in parallel. Each second indicator light L2 is a light-emitting diode (LED) capable of emitting monochromatic light, and the light emitted by different second indicator lights L2 can have different colors. To distinguish them, the two second indicator lights L2 are labeled L2-1 and L2-2 in FIG9 .

[0116] Based on the structure shown in Figure 9, as described in the above embodiment, of the two second indicator lights L2-1 and L2-2, one second indicator light L2-1 can be a red LED that emits red light, and the other second indicator light L2-2 can be a blue LED that emits blue light. When the smart interactive device is turned off, it can be indicated by controlling the second indicator light L2-1 to emit red light; when the smart interactive device is turned on, it can be indicated by controlling the second indicator light L2-2 to emit blue light. In other words, the on / off status of the smart interactive device can be indicated by a two-color LED. Here, the control instruction provided by the indicator light control terminal L_X can control the second indicator light L2-1 or the second indicator light L2-2 to light up. Accordingly, as shown in Figure 9, the indicator light control terminal L_X to which the input end of the second indicator light L2-1 is coupled can be identified as L_R; the indicator light control terminal L_X to which the input end of the second indicator light L2-2 is coupled can be identified as L_B.

[0117] Alternatively, referring to FIG. 9 , the second indicator light L2-1 and the second indicator light L2-2 can be integrated into the same chip R_B. The input terminal of the second indicator light L2-1 can be the first pin 1; the output terminal of the second indicator light L2-1 can be the second pin 2; the input terminal of the second indicator light L2-2 can be the third pin 3; and the output terminal of the second indicator light L2-2 can be the fourth pin 4. This is merely an illustrative example.

[0118] Optionally, as described in the above embodiment, the switch signal may include an infrared signal, i.e., the signal detection module 02 may detect an infrared signal, referred to as an infrared signal. Based on this, referring to FIG10 , which shows a schematic circuit diagram of a signal detection module 02 provided in an embodiment of the present disclosure, it can be seen that the signal detection module 02 may include an infrared detection chip U3. The infrared detection chip U3 may have a pull-up pin VS, a pull-down pin GND, and an output pin OUT.

[0119] The pull-up pin VDD of the infrared detection chip U3 can be coupled to an infrared receiving terminal IR_PW for detecting infrared signals via a thirteenth resistor R13. The pull-down pin GND of the infrared detection chip U3 can be coupled to ground. The output pin OUT of the infrared detection chip U3 can be coupled to an infrared transmitting terminal IR for transmitting signals based on the infrared signal. A ninth capacitor C9 can be connected in series between the infrared receiving terminal IR_PW and ground.

[0120] The infrared receiving end IR_PW can detect infrared signals and transmit signals to the SOC via the infrared transmitting end IR based on the detected infrared signals, so that the SOC can control the power on / off status of the intelligent interactive device.

[0121] Optionally, the circuit board 01 described in the embodiment of the present disclosure may include a printed circuit board (PCB). That is, modules implementing different functions in the embodiment of the present disclosure may be integrated on the same PCB to achieve an all-in-one design.

[0122] On this basis, in combination with Figure 8, Figure 11 shows a structural layout of an interactive integrated circuit provided by an embodiment of the present disclosure, including a front view, a side view, and a top view. Referring to Figure 11, it can be seen that along the target direction X1 parallel to the bearing surface of the circuit board 01, the outermost side can be integrated with a signal detection module 02 for detecting infrared signals; then a voice acquisition unit 0321-1 for collecting far-field voice signals can be integrated; then a second indication unit 042 for indicating the working status of the intelligent interactive device can be provided, including a second indicator light group 0421 with two second indicator lights L2; ​​then a first indication unit 041 for indicating the working status of the voice interaction module 03 can be provided, including a first indicator light group 0412 with four first indicator lights L1; finally, another voice acquisition unit 0321-2 for collecting far-field voice signals can be provided. That is, along the target direction X1, the signal detection module 02, the voice interaction module 03, and the status indication module 04 can be arranged at intervals. In addition, referring to Figure 11, it can be seen that the power supply component 031 included in the voice acquisition module 03 can be located separately on the other side of the circuit board 01.

[0123] Alternatively, referring to FIG. 11 , the distance d1 between each pair of adjacent first indicator lights L1 can be 8 millimeters (mm). Accordingly, the length d2 of the circuit board 01 occupied by the first indicator light group 0412 comprising four first indicator lights L1 can be 24 mm. Furthermore, the distance between the two voice collection units 0321-1 can be 68 mm. Of course, the data presented here is for illustrative purposes only.

[0124] Optionally, based on FIG11 , FIG12 further shows a schematic circuit layout of an interactive integrated circuit provided by an embodiment of the present disclosure, which shows the wiring layout and the positional relationship of each component, corresponding to FIG11 , and will not be repeated here.

[0125] It should be noted that the arrangement positions and arrangements of the various parts on the above-mentioned circuit board 01 are merely schematic illustrations and do not limit the embodiments of the present disclosure.

Moreover, the multiple modules can be arranged at intervals along one direction on the circuit board. In this way, a design in which modules performing different functions are integrated on one circuit board is realized, which can be beneficial to the design of intelligent interactive devices and greatly reduce the design cost.
