Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0045] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0046] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0047] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0048] In embodiments of this application, 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 limitation, 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 that element.

[0049] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0050] This application provides a human-computer interaction device that can be applied to vehicles, smart devices, etc. The term "vehicle" or other similar terms used in this application broadly encompass motor vehicles: for example, passenger vehicles including SUVs, buses, trucks, and various commercial vehicles; water transport vehicles including various boats and ships, and aircraft; and including hybrid vehicles, electric vehicles, hybrid-electric vehicles, hydrogen-powered vehicles, and other alternative fuel vehicles (e.g., fuels derived from resources other than petroleum). Smart devices can include various devices capable of carrying computer programs. Examples include access control devices, camera equipment, smart home appliances, and smart terminals.

[0051] Taking vehicles as an example, vehicles are typically equipped with human-machine interface (HMI) devices. These HMI devices are used to realize the input and output functions of the in-vehicle terminal. In some technical solutions, different components are used in the HMI device to realize the input and output functions separately, resulting in redundant structure, large space occupation, and high cost. Moreover, when the HMI device uses piezoelectric vibrators as input devices, it can only recognize simple interactive commands such as touch and press, making it difficult to realize complex interactions and limiting its application scenarios.

[0052] Reference Figure 1 and Figure 2 The human-computer interaction device provided in this application includes a piezoelectric component 100 and a control module 200. The piezoelectric component 100 is configured to generate vibration in response to a first electrical signal and to generate a second electrical signal in response to external vibration. The control module 200 includes a control unit 210 and an identification output component 220. The identification output component 220 is connected to the piezoelectric component 100 through a first transmission circuit T1 and a second transmission circuit T2, and is connected to the control unit 210 through a third transmission circuit T3. The identification output component 220, in response to the control of the control unit 210, outputs the first electrical signal to the piezoelectric component 100 through the first transmission circuit T1; or, the identification output component 220 receives and parses the second electrical signal through the second transmission circuit T2, and transmits the parsing result to the control unit 210 through the third transmission circuit T3. The control unit 210 controls the operating state of the identification output component 220 based at least on the parsing result.

[0053] In this embodiment, the piezoelectric component 100 can generate current under deformation using the piezoelectric effect, that is, the piezoelectric component 100 generates a second electrical signal in response to external vibration. For example, the piezoelectric component 100 deforms when pressed or struck, or deforms under the influence of air waves. The piezoelectric component 100 can also vibrate with current using the inverse piezoelectric effect, that is, the piezoelectric component 100 vibrates in response to a first electrical signal, which can be used to generate sound.

[0054] In this embodiment, the control module 200 includes electronic components such as a control unit 210 and an identification output component 220, as well as transmission circuits connecting the corresponding electronic components. It should be noted that the electronic components in the control module 200 are packaged as a single unit, which improves stability and facilitates miniaturization. Furthermore, the transmission circuits in this embodiment are only used to exemplify the transmission direction of the corresponding electrical signals and are not intended to limit their specific structure, positional relationships, or connection relationships.

[0055] In this embodiment, the first transmission circuit T1 may include multiple transmission lines to correspond to interfaces with different polarities of the piezoelectric component 100; the second transmission circuit T2 may be separately configured or integrated with the first transmission circuit T1. The third transmission circuit T3 may be a circuit with control functions, such as an Inter-Integrated Circuit (I2C) or a Serial Peripheral Interface (SPI).

[0056] In this embodiment, an electrical signal refers to a signal carrier that transmits information in the form of voltage or current and can change over time to carry and express information. The amplitude, frequency, or phase of the electrical signal can change over time to carry and transmit information. The electrical signal can be an analog signal, a digital signal, etc.

[0057] In this embodiment, the information transmitted by the first electrical signal can be vibration, sound effects, voice information, voiceprint information, etc., to drive the piezoelectric component 100 to vibrate, produce sound, or output voice information. Specifically, when the first electrical signal is used to drive the piezoelectric component 100 to vibrate, the first electrical signal can be used to transmit information such as vibration frequency, vibration time, and vibration amplitude; when the first electrical signal drives the piezoelectric component 100 to vibrate and produce sound, the first electrical signal can also be used to transmit information such as pitch, timbre, and loudness.

[0058] In this embodiment, the information transmitted by the second electrical signal may include at least one of the following: vibration frequency, vibration time, vibration amplitude, vibration waveform, and pressure difference information between different polarity interfaces of the piezoelectric component 100 when external vibration acts on the piezoelectric component 100. The control unit 210 can process the second electrical signal to analyze the source and type of the external vibration, such as the source being a living organism and the type being touch, knocking, collision, or voice information; or the source being a natural event and the type being rain, hail, or wind. The recognition output component 220 can analyze the content contained in the voice information by parsing the pressure difference information, etc.

[0059] In this embodiment, a first electrical signal is output by the identification output component 220 in response to the control of the control unit 210, and acts on the piezoelectric component 100 via the first transmission circuit T1, causing the piezoelectric component 100 to vibrate in response to the first electrical signal. Correspondingly, a second electrical signal is generated by the piezoelectric component 100 and transmitted to the identification output component 220 via the second transmission circuit T2. The identification output component 220 receives and analyzes the second electrical signal, and transmits the analysis result to the control unit 210 via the third transmission circuit T3.

[0060] In this embodiment of the application, the working state of the identification output component 220 may include an active state and a disabled state. The disabled state includes a sleep state, a high impedance state, a silent state, etc.; the active state includes an input state that is capable of or suitable for parsing the second electrical signal and an output state that is capable of or suitable for outputting the first electrical signal.

[0061] In this embodiment, the control unit 210 may control the identification output component 220 and other electronic devices directly without responding to other electrical signals; or, the control unit 210 may control the identification output component 220 and other components in response to a second electrical signal; or, the control unit 210 may control the identification output component 220 and other components in response to electrical signals input from other electronic devices.

[0062] In the human-computer interaction device of this application embodiment, the piezoelectric component 100 can generate vibration in response to a first electrical signal to serve as an output device in human-computer interaction. The piezoelectric component 100 can also generate a second electrical signal in response to external vibration to serve as an input device in human-computer interaction. The same piezoelectric component 100 can realize input / output multiplexing, thereby simplifying the structure.

[0063] Based on this, the control module 200 includes a control unit 210 and an identification output component 220. The control unit 210 is connected to the identification output component 220 through a third transmission circuit T3 and can control the working state of the identification output component 220. The identification output component 220 is connected to the piezoelectric component 100 through a first transmission circuit T1, thereby responding to the control of the control unit 210 by outputting a first electrical signal to the piezoelectric component 100.

[0064] The control module 200 allows a single piezoelectric component 100 to reuse different operating modes, thereby reducing redundant electronic components, space occupation, and cost. Furthermore, the identification output component 220 is connected to the piezoelectric component 100 via a second transmission circuit T2 to receive the second electrical signal generated by the piezoelectric component 100. The identification output component 220 analyzes the second electrical signal generated by the piezoelectric component 100 to obtain detailed analytical information about external vibrations, and transmits the analysis results to the control unit 210. This detailed analytical information serves as the input basis for the control unit 210 to control the operating state of the identification output component 220, thus enabling the switching of the piezoelectric component 100's operating mode in response to the information transmitted by external vibrations. This allows for more detailed and specific human-computer interaction, expanding application scenarios.

[0065] To facilitate the analysis of the second electrical signal and the output of the first electrical signal, refer to Figure 2 In some possible embodiments of this application, the identification output component 220 includes a signal processing unit 221 and an analog-to-digital converter 222 connected to each other. The signal processing unit 221 is connected to the first transmission circuit T1 and the third transmission circuit T3, respectively, and the analog-to-digital converter 222 is connected to the second transmission circuit T2. The signal processing unit 221 is configured to output a first electrical signal to the piezoelectric component 100 in response to a first control command from the control unit 210. The analog-to-digital converter 222 is used to convert the second electrical signal into a digital signal and transmit it to the signal processing unit 221. The signal processing unit 221 is configured to parse the converted second electrical signal and transmit the parsing result to the control unit 210. The first control command indicates at least one of the following: the operating state of the signal processing unit 221, the source of the sound source, and the audio identifier.

[0066] In this embodiment, the signal processing unit 221, in response to the control of the control unit 210, processes and acquires an audio source file to generate a first electrical signal, and transmits the first signal to the piezoelectric component 100; the signal processing unit 221 can also parse a second electrical signal and transmit the parsing result to the control unit 210. The signal processing unit 221 can be a digital signal processor (DSP), decoder, mixer, etc., and this embodiment does not impose any limitations on this.

[0067] In this embodiment, the analog-to-digital converter 222 is used to convert a continuous analog signal into a discrete digital signal, that is, to convert the analog second electrical signal generated by the piezoelectric component 100 into a digital form and transmit it to the signal processing unit 221 so that the signal processing unit 221 can analyze the converted second electrical signal. The analog-to-digital converter 222 can be a successive approximation type, an integral type, a parallel comparison type, a voltage-to-frequency conversion type, etc., and this embodiment does not impose any limitations on this.

[0068] In this embodiment, the first control command is issued by the control unit 210 to instruct the signal processing unit 221 to operate. The signal processing unit 221 may have operating states such as an active state and a disabled state, and the first control command is used to switch the operating state of the signal processing unit 221. Alternatively, the signal processing unit 221 is connected to at least two piezoelectric components 100, and the first control command can be used to instruct the piezoelectric component 100 that needs to vibrate, thereby achieving channel selection. Alternatively, the signal processing unit 221 is connected to both an external audio source module 600 and a built-in audio source module, and the first control command can be used to instruct the audio source to be either the external audio source module 600 or the built-in audio source module, and to instruct the signal processing unit 221 to obtain the corresponding audio file according to the audio identifier, thereby playing different audio content.

[0069] The human-computer interaction device of this application embodiment includes a signal processing unit 221 and a digital-to-analog converter. The digital-to-analog converter first processes the second electrical signal into a digital signal, which is then processed by the signal processing unit 221 for analysis, thus facilitating signal processing. The signal processing unit 221 responds to a first control command, enabling switching of its operating state and selecting the first electrical signal to be output based on the sound source and audio identifier indicated by the first control command, adapting to the interaction scenario.

[0070] It should be noted that when the signal processing unit 221 outputs the first electrical signal to the piezoelectric component 100, the second transmission circuit T2 can be disconnected to shield the second electrical signal. Alternatively, in some possible embodiments of this application, the second transmission circuit T2 includes a transmission line corresponding to any polarity; the signal processing unit 221 still receives the second electrical signal while outputting the first electrical signal and compares the received second electrical signal with the output first electrical signal. If the comparison result (e.g., the matching degree between the characteristic values ​​of the first and second electrical signals is lower than a preset threshold) indicates the presence of external vibration input (e.g., detecting that a user is tapping or touching the piezoelectric component 100), then the output of the first electrical signal is stopped.

[0071] To facilitate the analysis of the second electrical signal, refer to Figure 3 and Figure 4In some other possible embodiments of this application, the second transmission circuit T2 includes at least two transmission lines, each corresponding to a different polarity, and the second electrical signal includes the electrical signal transmitted through each transmission line.

[0072] In this embodiment, the second transmission circuit T2 is provided with transmission lines corresponding to the interfaces of different polarities of the piezoelectric component 100. Since the voltages output by the different polarities of the piezoelectric component 100 are not the same, there is a voltage difference in the electrical signals transmitted through the different transmission lines. The signal processing unit 221 integrates and processes the voltage difference signals transmitted through multiple different transmission lines, and can parse out more information carried by the second electrical signal, such as voice information.

[0073] For example, the second transmission circuit T2 includes two transmission lines, which are respectively connected to the positive and negative polarity interfaces of the piezoelectric component 100.

[0074] The human-computer interaction device of this application embodiment includes a second transmission circuit T2 comprising at least two transmission lines with different polarities, such that a differential pressure signal can be formed between the two transmission lines. The differential pressure signal has good stability, is not easily affected by external factors, and can carry more information so that the identification output unit can analyze the more information transmitted by the second electrical signal through the differential pressure signal.

[0075] To achieve richer interactive effects, refer to Figure 3 and Figure 4 In some possible embodiments of this application, the control module 200 further includes an adjustment component 230, which is connected between the signal processing unit 221 and the first transmission circuit T1. The third transmission circuit T3 includes a first sub-circuit T31 and a second sub-circuit T32. The control unit 210 is connected to the signal processing unit 221 through the first sub-circuit T31 and to the adjustment component 230 through the second sub-circuit T32. The adjustment component 230 includes a power adjustment unit 231, which is configured to adjust the power of the first electrical signal output by the signal processing unit 221 in response to the control of the control unit 210, and transmit the adjusted first electrical signal to the piezoelectric component 100 through the first transmission circuit T1.

[0076] In this embodiment, the first sub-circuit T31 can transmit the first control command from the control unit 210 to the signal processing unit 221, and can also transmit the parsing result from the signal processing unit 221 to the control unit 210. Exemplarily, the first sub-circuit T31 can be a serial communication circuit, such as an SPI circuit. The second sub-circuit T32 can be used to transmit the control command from the control unit 210 to the adjustment component 230. Exemplarily, the second sub-circuit T32 can be a serial communication circuit, such as an I2C circuit. The control unit 210 and the adjustment component 230 are connected via an I2C circuit, and the adjustment component 230 and the signal processing unit 221 can be connected via digital audio transmission lines such as Time-Division Multiplexing (TDM) lines or Integrated Circuit Built-in Audio Bus (Inter-ICSound, I2S).

[0077] In this embodiment, the power adjustment unit 231 can be used to adjust the power of the first electrical signal to match the operating power of the piezoelectric component 100, thereby driving the piezoelectric component 100 to vibrate. The power adjustment unit 231 can be a linear power amplifier, a solid-state power amplifier, a traveling wave tube amplifier, etc., and this embodiment does not limit it.

[0078] The human-computer interaction device of this application embodiment includes an identification output component 220 comprising a power adjustment unit 231 and a signal processing unit 221. The control unit 210 can control the working state, channel selection, sound source source and / or executed audio identifier of the instruction signal processing unit 221 through the first sub-circuit T31, and control the power adjustment unit 231 through the second sub-circuit T32 to adjust the power of the first electrical signal, thereby adjusting the vibration / sound generation effect of the piezoelectric component 100 and achieving richer interactive effects.

[0079] In order to adapt to more diverse vocal needs, refer to Figure 4 and Figure 5 In some possible embodiments of this application, the adjustment component 230 is connected to at least two piezoelectric components 100, and the adjustment component 230 further includes an output selection unit 232. The output selection unit 232 responds to a second control command from the control unit 210 to divide the first electrical signal into sub-signals and transmits the sub-signals to the corresponding piezoelectric components 100 respectively. The second control command at least instructs the adjustment component 230 to perform channel selection.

[0080] In this embodiment of the application, the adjustment component 230 is connected to at least two piezoelectric components 100 through the output selection unit 232. The output selection unit 232 can drive different piezoelectric components 100 to vibrate simultaneously or at different times based on the second control command, or it can drive different piezoelectric components 100 to produce the same or different vibrations.

[0081] The first electrical signal can be a time-division signal, which includes a division identifier. The output selection unit 232 divides the first electrical signal into multiple sub-signals according to the division identifier, so as to drive the corresponding piezoelectric components 100 respectively. This can enhance the stereo effect and provide richer sound effects and a better sense of space.

[0082] In this embodiment of the application, when multiple piezoelectric components 100 are provided, each piezoelectric component 100 can be individually connected to the signal processing unit 221, or different piezoelectric components 100 can be connected to the signal processing unit 221 via a bus, and different piezoelectric components 100 can be used as different types or the same type of input devices.

[0083] For example, the signal processing unit 221 is connected to two piezoelectric components 100 respectively. One piezoelectric component 100 is connected through two transmission lines to identify complex vibrations such as voice information; the other piezoelectric component 100 is connected through a single transmission line. The structure is simple and can be used to identify vibration type, vibration source, etc.

[0084] The human-computer interaction device of this application embodiment is provided with an output selection unit 232, which can drive different piezoelectric components 100 to perform time-division vibration and / or generate different vibrations based on the control unit 210, thereby achieving more complex output effects and adapting to a wider range of scenarios.

[0085] To adapt to diverse input requirements, refer to Figure 5 and Figure 6 In some possible embodiments of this application, the control module 200 further includes a fourth transmission circuit T4, which is connected between the piezoelectric component 100 and the control unit 210. The fourth transmission circuit T4 is used to transmit a second electrical signal. The control unit 210 is configured to control the operating state of the identification output component 220 in response to receiving the second electrical signal.

[0086] In this embodiment, the fourth transmission circuit T4 can be an input / output (I / O) bus. The fourth transmission circuit T4 can transmit the second electrical signal to the control unit 210. That is, the second electrical signal generated by the piezoelectric component 100 in response to external vibration can be directly transmitted to the control unit 210 via the fourth transmission circuit T4. This is suitable for situations where the input information, such as the source and type of vibration, is relatively simple, i.e., the human-machine interface device operates in vibration sensing mode. The control unit 210 can also switch the human-machine interface device to sound sensing mode based on the second electrical signal transmitted by the fourth transmission circuit T4. Alternatively, the second electrical signal can also be transmitted to the recognition output component 220 via the second transmission circuit T2, where it is parsed and the parsing result is transmitted to the control unit 210. This is suitable for situations where the information, such as voice information, is more complex, i.e., the human-machine interface device operates in sound sensing mode.

[0087] In this embodiment, the control unit 210 may respond to the second electrical signal transmitted by the fourth transmission circuit T4 and control the recognition output component 220 to switch to an active state so as to parse the second electrical signal to obtain voice information, etc.; or, the control unit 210 may respond to the second electrical signal transmitted by the fourth transmission circuit T4 and control the recognition output component 220 to switch to a disabled state to reduce power consumption.

[0088] The human-computer interaction device of this application embodiment is provided with a fourth transmission circuit T4, which enables the control unit 210 to directly receive the second electrical signal and sense external vibrations such as knocking and touching to realize the vibration sensing mode. Based on the recognition output component 220 receiving and parsing the second electrical signal to realize the sound sensing mode, the vibration sensing mode and the sound sensing mode can be reused to realize the switching of multiple working modes and adapt to diverse scenario requirements.

[0089] To simplify the structure, refer to Figure 6 and Figure 7 In some possible embodiments of this application, the human-computer interaction device further includes a mating part 300, which is used to input a first electrical signal and output a second electrical signal; the first transmission circuit T1, the second transmission circuit T2 and the fourth transmission circuit T4 are all connected to the mating part 300.

[0090] In this embodiment, the mating part 300 may be a component of the piezoelectric assembly 100. For example, the piezoelectric assembly 100 includes a circuit board on which the mating part 300 is provided. The mating part 300 may also be an adapter disposed between the piezoelectric assembly 100 and the control module 200, and the mating part 300 is used for bidirectional signal transmission between the piezoelectric assembly 100 and the control module 200.

[0091] In the human-computer interaction device of this application embodiment, the first transmission circuit T1, the second transmission circuit T2 and the fourth transmission circuit T4 are all connected to the mating part 300 to realize the centralized arrangement of multiple circuits, thereby simplifying the structure and facilitating circuit layout.

[0092] To protect the control unit 210 and the signal processing unit 221, refer to Figure 6 and Figure 7 In some possible embodiments of this application, at least one of the second transmission circuit T2 and the fourth transmission circuit T4 is provided with a voltage regulator unit 400 and / or an operational amplifier unit 500; wherein, the voltage regulator unit 400 is used to limit the strength of the first electrical signal flowing back to the signal processing unit 221 or the control unit 210, and to limit the strength of the second electrical signal sent to the signal processing unit 221 or the control unit 210; the operational amplifier unit 500 is used to adjust the voltage of the first electrical signal flowing back to the signal processing unit 221 or the control unit 210, and to adjust the voltage of the second electrical signal sent to the signal processing unit 221 or the control unit 210.

[0093] In this embodiment, the first transmission circuit T1, the second transmission circuit T2, and the fourth transmission circuit T4 are all connected to the same port of the piezoelectric component 100. It can be understood that the first electrical signal of the first transmission circuit T1 can not only be transmitted to the piezoelectric component 100, but also flow back to the signal processing unit 221 or the control unit 210 through the connected second transmission circuit T2 and fourth transmission circuit T4. By setting the voltage regulation unit 400 and / or the operational amplifier unit 500, the influence of this return signal can be reduced. At the same time, the voltage regulation unit 400 can limit the voltage when the volume of the piezoelectric component 100 is too loud, so as to avoid damage to the circuit due to excessive voltage.

[0094] In this embodiment, the voltage regulator 400 can be a linear regulator, such as a Zener diode or a three-terminal regulator. The voltage regulator 400 can also be a voltage regulator, and the output voltage of the voltage regulator can be adjusted according to actual needs to improve the flexibility of the device.

[0095] In this embodiment, the strength of the electrical signal can refer to its voltage parameters, current parameters, power density, etc. For example, a voltage regulator 400 is provided between the piezoelectric component 100 and the signal processing unit 221 to limit the first electrical signal flowing back to the signal processing unit 221, thereby protecting the signal processing unit 221. It is understood that, in the case where an analog-to-digital converter 222 is provided, the voltage regulator 400 can be located between the analog-to-digital converter 222 and the piezoelectric component 100. Furthermore, in the case where the second transmission circuit T2 includes multiple transmission lines, a voltage regulator 400 needs to be provided for each transmission line.

[0096] In this embodiment, adjusting the voltage of the electrical signal means limiting or increasing the voltage of the corresponding electrical signal to match the interface input voltage of the signal processing unit 221 or the control unit 210. For example, the fourth transmission circuit T4 is equipped with an operational amplifier unit 500, which adjusts the voltage of the second electrical signal to match the interface input voltage of the control unit 210.

[0097] The human-computer interaction device of this application embodiment limits the strength of the electrical signal by setting a voltage regulator unit 400 and / or adjusting the voltage of the electrical signal by setting an operational amplifier unit 500, so as to adapt to the working parameters of the control unit 210 and the signal processing unit 221. This can protect the control unit 210 and the signal processing unit 221 and reduce signal distortion.

[0098] For easier switching of input modes, please refer to... Figure 7 and Figure 8 In some possible embodiments of this application, the control module 200 further includes a controllable switch 240, and at least one of the second transmission circuit T2 and the fourth transmission circuit T4 is provided with an execution terminal of the controllable switch 240. The control terminal of the controllable switch 240 is connected to the control unit 210. In response to the control of the control unit 210, the controllable switch 240 connects or disconnects the corresponding second transmission circuit T2 or the fourth transmission circuit T4.

[0099] In this embodiment, the controllable switch 240 can be a transistor, a mechanical switch, an electromagnetic switch, etc. The transistor can be a bipolar transistor, a field-effect transistor, a complementary metal-oxide-semiconductor, a carbon nanotube transistor, etc. This embodiment does not limit the types of transistors.

[0100] In this embodiment, the controllable switch 240 includes a control terminal and an execution terminal. The control terminal can be connected to a control unit 210, etc., while the execution terminal is connected to the controlled circuit. When the control terminal receives a corresponding control electrical signal, the execution terminal connects the controlled circuit so that the corresponding electrical signal can be transmitted through the controlled circuit; or, the execution terminal disconnects the controlled circuit to prevent the controlled circuit from transmitting electrical signals.

[0101] In one possible embodiment of this application, the second transmission circuit T2 and the fourth transmission circuit T4 are respectively provided with the execution terminal of the controllable switch 240. The control unit 210 controls the second transmission circuit T2 to be connected and the fourth transmission circuit T4 to be disconnected, so that the human-machine interaction device works in the sound perception mode; or, the control unit 210 controls the second transmission circuit T2 to be disconnected and the fourth transmission circuit T4 to be connected, so that the human-machine interaction device works in the vibration perception mode.

[0102] In the human-computer interaction device of this application embodiment, the control unit 210 adjusts the connection or disconnection of the second transmission circuit T2 and the fourth transmission circuit T4 through the controllable switch 240, thereby adjusting the transmission path of the second electrical signal to adapt to different input modes.

[0103] To facilitate the output of the human-computer interaction device, refer to Figure 5 and Figure 6 In some possible embodiments of this application, the control module 200 further includes a fourth transmission circuit T4 connected between the piezoelectric component 100 and the control unit 210 for transmitting a second electrical signal. The control unit 210 is configured to switch the identification output component 220 to an output state in response to the parsing result, so that the identification output component 220 outputs a first electrical signal; and / or, the control unit 210 is configured to control the second transmission circuit T2 and the fourth transmission circuit T4 to disconnect in response to the parsing result.

[0104] In this embodiment, the control unit 210 can control the working state of the identification output component 220 and the on / off state of the second transmission circuit T2 and the fourth transmission circuit T4 based on the analysis results. For example, the control unit 210 controls the identification output component 220 to switch to the output state, that is, the signal processing unit 221 and the adjustment component 230 both enter the active state and can output the first electrical signal to the piezoelectric component 100;

[0105] In addition, the control unit 210 can also control the second transmission circuit T2 and the fourth transmission circuit T4 to disconnect via the controllable switch 240, so as to avoid the first electrical signal backflow from adversely affecting the control unit 210 and the identification output component 220.

[0106] In the human-computer interaction device of this application embodiment, the control unit 210 controls the recognition output component 220 to output a first electrical signal based on the analysis result, so that the piezoelectric component 100 vibrates to produce sound. The control unit 210 can also control the second transmission circuit T2 and the fourth transmission circuit T4 to disconnect, so as to reduce the influence of the return electrical signal.

[0107] In order to obtain external vibration information in a timely manner, refer to Figure 8 and Figure 9 In some possible embodiments of this application, the control unit 210 is configured to control the identification output component 220 to switch to a disabled state in response to a third electrical signal; and / or, the control unit 210 is configured to control the second transmission circuit T2 to disconnect and control the fourth transmission circuit T4 to connect in response to a third electrical signal; wherein the third electrical signal is generated by the external audio source module 600 or the identification output component 220, and the third electrical signal is used to indicate the end of the first electrical signal output.

[0108] In this embodiment, the third electrical signal can be generated by the external audio source module 600 or the identification output component 220 to indicate the end of the first electrical signal output. For example, after the external audio source module 600 sends the first electrical signal to the identification output component 220, it generates the third electrical signal and sends it to the control unit 210. Alternatively, after the signal processing unit 221 of the identification output component 220 sends the first electrical signal to the adjustment component 230, it generates the third electrical signal and sends it to the control unit 210.

[0109] In this embodiment, the control unit 210 can switch the identification output component 220 to a disabled state in response to the third electrical signal, and control the second transmission circuit T2 to be disconnected and the fourth transmission circuit T4 to be connected through the controllable switch 240, so that the second electrical signal generated by the piezoelectric component 100 can be directly transmitted to the control unit 210 through the fourth transmission circuit T4, so that the human-machine interaction device works in vibration sensing mode.

[0110] In the human-computer interaction device of this application embodiment, the external sound source module 600 or the recognition output component 220 can generate a third electrical signal after the first electrical signal is output. The control unit 210 responds to the third electrical signal by controlling the recognition output component 220 to switch to a disabled state, and / or disconnecting the second transmission circuit T2 and connecting the fourth transmission circuit T4, so that the human-computer interaction device works in vibration sensing mode to obtain external vibration information in a timely manner.

[0111] To obtain more complex input information, refer to Figure 6 and Figure 7 In some possible embodiments of this application, the control unit 210 is configured to control the identification output component 220 to switch to an input state in response to the second electrical signal, so that the identification output component 220 receives and parses the second electrical signal; and / or, the control unit 210 is configured to control the second transmission circuit T2 to connect and control the fourth transmission circuit T4 to disconnect in response to the second electrical signal.

[0112] In this embodiment, the control unit 210 can control the identification output component 220 to switch to the input state, that is, the signal processing unit 221 switches to the active state, which can receive the second electrical signal and perform analysis, and send the analysis result to the control unit 210.

[0113] In addition, the control unit 210 can also control the second transmission circuit T2 to be connected and the fourth transmission circuit T4 to be disconnected, that is, the second electrical signal generated by the piezoelectric component 100 is transmitted to the identification output component 220 through the second transmission circuit T2 without passing through the fourth transmission circuit T4.

[0114] Based on this, the human-computer interaction device operates in the sound perception mode. It should be noted that the control unit 210 can also control the human-computer interaction device to operate in the sound perception mode based on the analysis results of the recognition output component 220. For example, when the recognition output component 220 outputs a first electrical signal, the received second electrical signal is compared with the output first electrical signal. If the comparison result indicates the presence of external vibration input, the output of the first electrical signal is stopped and the device switches to the sound perception mode.

[0115] In the human-computer interaction device of this application embodiment, the control unit 210 controls the identification output component 220 to switch to the input state, and controls the second transmission circuit T2 to be connected and the fourth transmission circuit T4 to be disconnected, so that the human-computer interaction device works in the sound perception mode, which can analyze sound information to realize more complex human-computer interaction.

[0116] In some possible embodiments of this application, the external vibration is an air wave vibration. Air wave vibration refers to a vibration wave transmitted through a gas medium. Air wave vibration can be used to transmit sound signals, such as the sound information of a user's speech.

[0117] The human-computer interaction device of this application embodiment has the ability to perceive sound by analyzing air wave vibrations, and can switch between the sound perception mode and other working modes.

[0118] In order to broaden the ways to obtain audio sources, refer to Figure 8 and Figure 9 In some possible embodiments of this application, the human-computer interaction device further includes an external audio source module 600, which is connected to the recognition output component 220 and the control unit 210 respectively. The external audio source module 600 is configured to send a first electrical signal to the recognition output component 220 in response to a third control command from the control unit 210, so that the recognition output component 220 outputs the first electrical signal; the third control command at least indicates the parsing result.

[0119] In this embodiment, the external audio source module 600 may include an external processor, which generates a first electrical signal through a program and sends it to the recognition output component 220. Alternatively, the external audio source module 600 may include an external memory, an external processor, etc. The external memory is used to store audio files, and the external processor can respond to the control of the control unit 210, retrieve the audio file from the external memory, process it into a first electrical signal, and send it to the recognition output component 220.

[0120] In this embodiment, the external audio source module 600 can be a vehicle infotainment system, a personal computer (PC), a laptop computer, a mobile phone, an all-in-one computer, a PDA, a tablet computer, or a portable device (such as a mobile phone or a navigation and positioning device), an industrial control computer, or a smart home device (such as a smart speaker or access control device), etc. This embodiment does not impose any limitations on this. When the human-machine interaction device is installed in the vehicle body, the external audio source module 600 can be a component of the vehicle terminal (e.g., a vehicle infotainment system), meaning the human-machine interaction device interacts with the vehicle terminal so that the vehicle terminal provides a first electrical signal to the identification output component 220.

[0121] In this embodiment, the external audio source module 600 can be connected to the control unit 210 via a CAN bus, such as a CAN transceiver 260. Specifically, the external audio source module 600 can be connected to the CAN transceiver via the CAN bus and then to the control unit 210. The external audio source module 600 can be connected to the signal processing unit 221 via, for example, a TDM line or an I2S bus. It should be noted that when the external audio source module 600 is an electronic terminal such as a vehicle infotainment system with a processor, the signal processing unit 221 can also send the parsing results to the processor of the vehicle infotainment system, which then acts as the control unit 210.

[0122] In the human-computer interaction device of this application embodiment, the control unit 210 can control the external audio source module 600 using the analysis result of the second electrical signal, and send the first electrical signal to the recognition output component 220 through the external audio source module 600. The external audio source module 600 has the effect of being easy to replace and expand, so that the human-computer interaction device can be adapted to different external audio source modules 600, enriching the application scenarios of the human-computer interaction device.

[0123] To facilitate the signal processing unit 221 in acquiring the sound source, refer to Figure 8 and Figure 9 In some possible embodiments of this application, the control module 200 further includes a built-in storage unit 250, which is connected to a signal processing unit 221. The signal processing unit 221 is configured to retrieve an audio file from the built-in storage unit 250 to output a first electrical signal in response to a first control command from the control unit 210.

[0124] In this embodiment, the built-in storage unit 250 is used to store audio files. The control unit 210 instructs the signal processing unit 221 to switch to the active mode through a first control command. The signal processing unit 221 can respond to the first control command to obtain the corresponding audio file from the storage unit according to the audio identifier. The signal processing unit 221 generates a corresponding first electrical signal according to the audio file and drives the piezoelectric component 100 to vibrate via the power adjustment unit 231.

[0125] The human-computer interaction device of this application embodiment includes a recognition output component 220 with a built-in storage unit 250. The signal processing unit 221 can obtain audio files from the built-in storage unit 250 and convert them into a first electrical signal output. Since the built-in storage unit 250 is located in the recognition output component 220, it is more convenient to obtain the files and can respond more quickly, thus improving the efficiency of human-computer interaction.

[0126] To facilitate the control of human-computer interaction devices, refer to Figure 9 In some possible embodiments of this application, the human-computer interaction device further includes an input component 700, which is connected to the control unit 210. The input component 700 is configured to generate a fourth electrical signal in response to an operation, and the control unit 210 is configured to control the operating state of the identification output component 220 in response to the fourth electrical signal.

[0127] In this embodiment, the input component 700 may include buttons, a touchpad, a microphone, a keyboard, a camera, etc. The input component 700 may also include corresponding control circuitry. When triggered, the input component 700 generates a fourth electrical signal. The control unit 210 can control the identification output component 220 to switch its operating state according to the fourth electrical signal, for example, switching the identification output component 220 to an active state or a disabled state. The control unit 210 can also control the controllable switch 240 according to the fourth electrical signal to switch the human-machine interface device to an output mode, a vibration sensing mode, or a sound sensing mode. The output mode is the mode in which the control unit 210 controls the identification output component 220 to drive the piezoelectric component 100 to vibrate and produce sound.

[0128] In the human-computer interaction device of this application embodiment, the control unit 210 is connected to the input component 700. The operator can send a fourth electrical signal to the control unit 210 through the input component 700. The control unit 210 responds to the fourth electrical signal to control the working state of the identification output component 220, making the operation more flexible and compatible with different human-computer interaction methods, and supporting more diversified interaction methods.

[0129] It should be noted that, unless otherwise specified, all connections between the aforementioned electronic components (such as control unit 210, signal processing unit 221, external audio source module 600, built-in memory, piezoelectric component 100, etc.) are electrical connections. These electrical connections can be wired or wireless. Wired connections, such as those achieved through wire harnesses, flexible circuit boards, or PCBs, offer structural stability and strong anti-interference capabilities. Wireless connections, such as wireless LAN, Bluetooth, or Wi-Fi, enable long-distance communication and have a simple structure.

[0130] Based on this, the present application provides a vehicle, which includes a vehicle body and a human-machine interaction device according to the present application. The vehicle body includes at least one structural member 800, which includes at least one of the following: an outer body panel, an interior panel, and a vehicle component. The vehicle component is connected to the outer body panel or the interior panel. At least one structural member 800 is connected to the human-machine interaction device.

[0131] In this embodiment, the vehicle body may include an on-board terminal, and the human-machine interaction device is electrically connected to the on-board terminal. One or more human-machine interaction devices may be installed on the vehicle body, or the human-machine interaction device may include multiple piezoelectric components 100, which may be installed at different locations on the vehicle body. It should be noted that the structural component 800 is connected to the human-machine interaction device; the entire human-machine interaction device may be located on the structural component 800, or the piezoelectric components 100 in the human-machine interaction device may be located on the structural component 800, so that the piezoelectric components 100 are used for vibration, sound generation, or sensing at corresponding locations.

[0132] In this embodiment, structural component 800 includes at least one of the following: exterior body panels, interior body panels, and vehicle components. The vehicle components are connected to the exterior body panels or interior body panels. Exterior body panels include roof panels, engine compartment hoods, storage box lids, pillars (such as B-pillars), front / rear fenders, doors, bumpers, roof racks, rearview mirror covers, etc.; interior body panels include headliners, floors, dashboards, door panels, center console panels, pillar guards, window sills, etc.; vehicle components include seats, body beams, body pillars, steering wheels, armrest boxes, rearview mirrors, sun visors, etc.

[0133] In this embodiment, the piezoelectric component 100 can drive the structural component 800 to vibrate and produce sound. Therefore, when the piezoelectric component 100 is installed on the structural component 800 such as the outer panel of the vehicle body, it can be installed on the inner side of the structural component 800, which has little impact on the vibration and sound production effect. Furthermore, the structural component 800 provides protection for the piezoelectric component 100, which also helps to simplify the structure.

[0134] The vehicle in this application embodiment includes at least one structural member 800 for installing a human-machine interaction device. The human-machine interaction device can be installed at a suitable position on the vehicle body as needed, making the deployment of the human-machine interaction device more convenient, so that the vehicle can realize a variety of human-machine interaction functions.

[0135] Furthermore, this application provides a control method for a human-computer interaction device, applied to a control unit 210, with reference to... Figure 10 The control method includes:

[0136] S100: In response to receiving the second electrical signal, control the identification output component 220 to switch to the input state so that the identification output component 220 can receive and parse the second electrical signal and generate a parsing result;

[0137] S200: In response to receiving the parsing result, control the identification output component 220 to switch to the output state so that the identification output component 220 outputs the first electrical signal;

[0138] The identification output component 220 is connected to the piezoelectric component 100 through the first transmission circuit T1 and the second transmission circuit T2. The first transmission circuit T1 is used to transmit the first electrical signal, and the second transmission circuit T2 is used to transmit the second electrical signal. The first electrical signal is used to excite the piezoelectric component 100 to generate vibration, and the second electrical signal is generated by the piezoelectric component 100 in response to external vibration.

[0139] In this embodiment, the control unit 210 responds to the second electrical signal by acquiring the second electrical signal through the fourth transmission circuit T4 and determining the type and source of external vibration based on the second electrical signal. If the external vibration is determined to be a complex input such as air wave vibration caused by voice information, the control unit 210 controls the recognition output component 220 to switch to the input state. Alternatively, in the output state of the recognition output component 220, the recognition output component 220 receives the second electrical signal through the fourth transmission circuit T4 and compares the second electrical signal with the output first electrical signal. If the comparison result (e.g., the matching degree between the feature value of the first electrical signal and the feature value of the second electrical signal is lower than a preset threshold) indicates the presence of external vibration input, the control unit 210 stops outputting the first electrical signal so that the human-computer interaction device can switch to the input state (such as vibration sensing mode or sound sensing mode) in a timely manner.

[0140] In this embodiment, the control component controls the identification output component 220 to switch to the input state. Specifically, the control signal processing unit 221 and the analog-to-digital conversion unit 222 are switched to the active state. The analog-to-digital conversion unit 222 receives the second electrical signal and converts it into a digital signal. The signal processing unit 221 parses the digitally processed second electrical signal and sends the parsing result to the control unit 210.

[0141] In this embodiment, the control unit 210 can control the recognition output component 220 to switch to different working states in response to the analysis result, thereby correspondingly switching the human-computer interaction device to output mode, sound perception mode, vibration perception mode, etc. Specifically, when the analysis result indicates that external feedback is required (e.g., a reply to the user is needed), the human-computer interaction device is switched to output mode, and the piezoelectric component 100 is driven to emit sound through the first electrical signal; when the analysis result indicates that external vibration of the first vibration type is required (e.g., the user needs to input tapping), the human-computer interaction device is switched to vibration perception mode; when the analysis result indicates that external vibration of the second vibration type is required (e.g., the user needs to input voice), the human-computer interaction device is switched to sound perception mode; when the analysis result indicates that no external feedback is required, the human-computer interaction device is switched to a standby working mode, such as vibration perception mode.

[0142] The control method of the human-computer interaction device in this application embodiment involves an identification output component 220 parsing a second electrical signal and transmitting the parsing result to a control unit 210. The control unit 210 then controls the working state of the identification output component 220 based at least on the parsing result. By setting the identification output component 220, more information contained in the second electrical signal can be parsed, so as to achieve more detailed and specific human-computer interaction and broaden the application scenarios.

[0143] To facilitate the acquisition of the second electrical signal, refer to Figure 11 In some possible embodiments of this application, the control unit 210 is also connected to the controllable switch 240, which is at least provided in the second transmission circuit T2;

[0144] The method also includes:

[0145] S110: In response to receiving the second electrical signal, controllable switch 240 is controlled to switch the second transmission circuit T2 to the connected state.

[0146] In this embodiment, the second transmission circuit T2 is used to connect the piezoelectric component 100 and the identification output component 220. When the human-machine interaction device needs to work in the sound perception mode, the control unit 210 controls the controllable switch 240 to connect the second transmission circuit T2, so that the second electrical signal can be transmitted to the identification output component 220 via the second transmission circuit T2, so that it can be parsed by the identification output component 220.

[0147] The control method of the human-computer interaction device in this application embodiment, when receiving the second electrical signal, controls the controllable switch 240 to switch the second transmission circuit T2 to the connected state, which can facilitate the identification of the output component 220 to obtain and parse the second electrical signal.

[0148] To facilitate switching between different working modes, please refer to... Figure 11 In some possible embodiments of this application, the control unit 210 is also connected to the controllable switch 240, which is at least provided in the second transmission circuit T2;

[0149] The method also includes:

[0150] S210: In response to receiving the parsing result, controllable switch 240 is controlled to switch the second transmission circuit T2 to the off state.

[0151] In this embodiment, the second transmission circuit T2 is used to connect the piezoelectric component 100 and the identification output component 220. The control unit 210 controls the controllable switch 240 to disconnect the second transmission circuit T2. When the human-machine interaction device is working in the output mode, the impact of the first electrical signal backflow on the identification output component 220 can be reduced. When the human-machine interaction device is working in the vibration sensing mode, the second electrical signal is not transmitted through the second transmission circuit T2, but is directly transmitted to the control unit 210, which can avoid the conflict between the two second electrical signals.

[0152] The control method of the human-computer interaction device in this application embodiment, wherein the control unit 210 controls the second transmission circuit T2 to disconnect, can reduce the influence of the return electrical signal and also avoid conflicts caused by the input of multiple second electrical signals.

[0153] To facilitate the vibration of the piezoelectric component 100, refer to... Figure 12 In some possible embodiments of this application, the identification output component 220 includes a signal processing unit 221 and an adjustment component 230;

[0154] After receiving the parsing result, the method also includes:

[0155] S310: Based on the analysis results, generate a first control command to control the signal processing unit 221 to output a first electrical signal to the adjustment component 230; and / or,

[0156] S320: Generate a second control command to control the regulating component 230 to process the first electrical signal.

[0157] In this embodiment, when the human-computer interaction device is operating in output mode, the control unit 210 can instruct the signal processing unit 221 to operate via a first control command. For example, in response to the first control command, the signal processing unit 221 retrieves a corresponding audio source file from the external audio source module 600 or the built-in storage unit 250, generates a first electrical signal based on the audio source file, and sends the first electrical signal to the adjustment component 230. The first electrical signal may be a time-division signal.

[0158] In this embodiment, when the human-computer interaction device is operating in output mode, the control unit 210 can instruct the adjustment component 230 to operate via a first control command. For example, the output selection unit 232 of the adjustment component 230 performs channel selection, and the power adjustment unit 231 of the adjustment component 230 adjusts the power of the first electrical signal.

[0159] The control method of the human-computer interaction device in this application embodiment can control the signal processing unit 221 and the adjustment component 230 workpiece respectively through the first control command and the second control command, so as to perform corresponding output according to the interaction requirements.

[0160] To enrich the output format, in some possible embodiments of this application, the first control command instructs at least one of the working state of the signal processing unit 221, the source of the sound source, and the audio identifier, and the second control command instructs at least the adjustment component 230 to perform channel selection processing and / or power adjustment processing. The channel selection processing includes dividing the first electrical signal into sub-signals and transmitting the sub-signals to the corresponding piezoelectric components 100 respectively.

[0161] In this embodiment, the operating state of the signal processing unit 221 may include an active mode, a disabled mode, etc. The sound source can be an external sound source module 600 or a built-in storage unit 250, and the audio identifier is used to indicate the audio file. For example, when the control unit 210 needs to obtain user voice information, the first control command instructs the signal processing unit 221 to switch to the active mode, and obtains the corresponding audio file from the built-in storage unit 250 according to the audio identifier. After parsing the audio file, a first electrical signal is generated, which drives the piezoelectric vibrator to vibrate and produce sound through the adjustment component 230 to inform the user that voice information input is possible.

[0162] In this embodiment, the second control command can instruct the output selection unit 232 to perform channel selection processing, that is, to divide the first electrical signal into multiple sub-signals and transmit the sub-signals to the corresponding piezoelectric components 100 respectively, so that different piezoelectric components 100 produce different vibration effects. The second control command can also instruct the power adjustment component 230 to adjust the power of the first electrical signal. For example, based on the second control command, the output selection unit 232 divides the first electrical signal into two sub-signals, and the power adjustment component 230 amplifies the power of the two sub-signals and transmits them to the two corresponding piezoelectric components 100, so that the corresponding piezoelectric components 100 vibrate.

[0163] The control method of the human-computer interaction device in this application embodiment can achieve diverse outputs by switching the working state of the signal processing unit 221, selecting the sound source, and adjusting the channel and power of the adjustment component 230, thereby enriching the interaction forms.

[0164] In order to control the state of the identification output component 220, refer to Figure 13 In some possible embodiments of this application, after the step of controlling the identification output component 220 to switch to an output state in response to receiving the parsing result, so that the identification output component 220 outputs a first electrical signal, the method further includes:

[0165] S400: In response to determining that the identification output component 220 stops outputting the first electrical signal, the identification output component 220 is controlled to switch to a disabled state or an input state based on the indication content of the first electrical signal.

[0166] In this embodiment of the application, the content indicated by the first electrical signal may be content that requires the user to respond with voice, such as informing the user to input voice information. When the user needs to input voice information, the recognition output component 220 is controlled to switch to the input state in order to obtain the user's voice information.

[0167] Furthermore, the content indicated by the first electrical signal can be content that requires no user response, or only requires the user to perform non-voice responses such as touch or tapping. For example, the first electrical signal can indicate that the user needs to tap, and can also indicate the location or number of taps. After the piezoelectric component 100 outputs information based on the vibration of the first electrical signal, no user voice response is required. The control recognition output component 220 switches to a disabled state, that is, switches to vibration sensing mode, which can reduce interference to other devices and is also more energy-efficient and environmentally friendly.

[0168] The control method of the human-computer interaction device in this application embodiment controls the identification output component 220 to switch working states through the content indicated by the first electrical signal, which is more in line with actual interaction needs and can switch the human-computer interaction device to a suitable working mode in a timely manner.

[0169] To adapt to different interaction scenarios, refer to Figure 14 In some possible embodiments of this application, the step of controlling the identification output component 220 to switch to a disabled state or an input state based on the indication content of the first electrical signal includes:

[0170] S410: In response to determining that the first electrical signal indicates the human-machine interface device is operating in vibration sensing mode, control the identification output component 220 to switch to a disabled state; or...

[0171] S420: In response to determining that the first electrical signal indicates that the human-machine interaction device is operating in the auditory perception mode, control the recognition output component 220 to switch to the input state;

[0172] Among them, the vibration sensing mode is used to identify external vibrations with a first vibration type; the sound sensing mode is used to identify external vibrations with a second vibration type.

[0173] In this embodiment, the first type of external vibration can be vibrations propagated through a solid or liquid medium, such as touching, tapping, or colliding. The second type of vibration can be air wave vibrations generated by a sound source. It is understood that the signal of the second type of vibration is more complex and requires analysis by the identification output component 220.

[0174] In one example, the human-computer interaction device engages in voice dialogue with the user. The content indicated by the first electrical signal requires a voice response from the user. The control component controls the recognition output component 220 to switch to the input state, that is, the signal processing unit 221 and the analog-to-digital conversion unit switch to the active state, so that the human-computer interaction device operates in the auditory perception mode.

[0175] In another example, during human-computer interaction, the user needs to perform a touch operation. The content indicated by the first electrical signal does not require a voice response from the user. The control component controls the recognition output component 220 to switch to a disabled state, so that the human-computer interaction device works in vibration sensing mode, so that the second electrical signal generated by the user's touch can be directly transmitted to the control unit 210 via the fourth transmission circuit T4.

[0176] The control method of the human-computer interaction device in this application embodiment switches the human-computer interaction device to vibration sensing mode or sound sensing mode according to the indication of the first electrical signal, so as to adapt to different interaction scenarios.

[0177] To facilitate the operation of the human-computer interaction device in vibration sensing mode, refer to Figure 15 In some possible embodiments of this application, the identification output component 220 includes a signal processing unit 221, and the control unit 210 is also connected to a controllable switch 240, which is at least disposed in the second transmission circuit T2.

[0178] In response to determining that the human-machine interface device is operating in vibration sensing mode, the step of controlling the identification output component 220 to switch to a disabled state includes:

[0179] S411: In response to determining that the human-machine interaction device is operating in vibration sensing mode, the controllable switch 240 is controlled to switch the second transmission circuit T2 to the off state, and the signal processing unit 221 is controlled to stop receiving the second electrical signal.

[0180] In this embodiment, the control unit 210 can switch the second transmission circuit T2 to an off state via a controllable switch 240 to prevent the second electrical signal from being transmitted to the signal processing unit 221. The control unit 210 can also control the signal processing unit 221, mode conversion unit, etc., to switch to a disabled state, thereby stopping the reception of the second electrical signal to avoid conflict with the second electrical signal directly received by the control unit 210.

[0181] To facilitate switching between vibration sensing mode and sound sensing mode, refer to Figure 16 In some possible embodiments of this application, the controllable switch 240 is also disposed in the fourth transmission circuit T4, which is connected between the control unit 210 and the piezoelectric component 100 for transmitting the second electrical signal; the method further includes at least one of the following steps:

[0182] S510: In response to receiving the second electrical signal, controllable switch 240 is controlled to switch the fourth transmission circuit T4 to the off state;

[0183] S520: In response to the analysis result of the received second electrical signal, controllable switch 240 is controlled to switch the fourth transmission circuit T4 to the off state;

[0184] S530: In response to determining that the human-machine interface device is operating in vibration sensing mode, controllable switch 240 is controlled to switch the fourth transmission circuit T4 to the connected state.

[0185] In this embodiment, the control unit 210 can determine the operating mode of the human-machine interface device based on the second electrical signal transmitted by the fourth transmission circuit T4, i.e., the second electrical signal received in vibration sensing mode. The control unit 210 can also determine the operating mode of the human-machine interface device based on the analysis result of the second electrical signal transmitted by the first sub-circuit T31, i.e., the analysis result of the second electrical signal received in sound sensing mode. When the human-machine interface device needs to operate in sound sensing mode or output mode, the controllable switch 240 is controlled to switch the fourth transmission circuit T4 to an off state.

[0186] In this embodiment of the application, when it is determined that the human-computer interaction device needs to work in vibration sensing mode, for example according to the content indicated by the first electrical signal, the control unit 210 controls the controllable switch 240 to switch the fourth transmission circuit T4 to the connected state so that the second electrical signal can be directly transmitted to the control unit 210 through the fourth transmission circuit T4, thereby switching the human-computer interaction device to vibration sensing mode.

[0187] The control method of the human-computer interaction device in this application embodiment controls the controllable switch 240 to connect or disconnect the fourth circuit, thereby changing the transmission path of the second electrical signal and facilitating the switching of the working mode of the human-computer interaction device.

[0188] Reference Figure 17 , Figure 18 , Figure 19 , Figure 20 and Figure 21In some possible embodiments of this application, the human-computer interaction device includes a control module 200 and a piezoelectric component 100. The control module 200 includes a control unit 210 and an identification output component 220. The identification output component 220 includes a signal processing unit 221, an adjustment component 230, and an analog-to-digital converter 222. The adjustment component 230 and the analog-to-digital converter 222 are both connected to the signal processing unit 221. The adjustment component 230 and the piezoelectric component 100 are connected via a first transmission circuit T1, the piezoelectric component 100 and the analog-to-digital converter 222 are connected via a second transmission circuit T2, the control unit 210 and the signal processing unit 221 are connected via a first sub-circuit T31, and the control unit 210 and the identification output component 220 are connected via a second sub-circuit T32. (Refer to...) Figure 20 In one embodiment, the control unit 210 is not directly connected to the piezoelectric component 100, and the second electrical signal is transmitted only through the second transmission circuit T2; see reference. Figure 21 In another embodiment, the control unit 210 and the piezoelectric component 100 are connected via a fourth transmission circuit T4, and the second electrical signal can be connected via a second transmission circuit T2 and a fourth transmission circuit T4, respectively.

[0189] In addition, an external audio source module 600 can be provided, which is connected to the control unit 210 and the signal processing unit 221 respectively. The signal processing unit 221 can also be connected to the built-in storage unit 250. The adjustment component 230 also includes an output selection unit 232 and a power adjustment unit 231 to facilitate the adjustment of the output effect. The second transmission circuit T2 is equipped with a voltage regulator unit 400, and the fourth transmission circuit T4 is equipped with an operational amplifier unit 500 to protect the control unit 210 and the output identification component 220.

[0190] Based on this, the human-computer interaction device has an output mode, a vibration sensing mode, and a sound sensing mode that can be switched between each other. In the output mode, information is output to the outside world through the vibration of the piezoelectric component 100; the vibration sensing mode is used to acquire external operations or environmental changes of the first vibration type, such as touch or tapping; and the sound sensing mode is used to acquire external voice of the second vibration type, such as user voice.

[0191] Furthermore, when the signal processing unit 221 outputs the first electrical signal to the piezoelectric component 100, the second transmission circuit T2 can be disconnected to shield the second electrical signal from the signal processing unit 221. Alternatively, the signal processing unit 221 may still receive the second electrical signal while outputting the first electrical signal, and compare the received second electrical signal with the output first electrical signal. If the comparison result (e.g., the matching degree between the characteristic values ​​of the first and second electrical signals is lower than a preset threshold) indicates the presence of external vibration input (e.g., detecting that a user is tapping or touching the piezoelectric component 100), then the output of the first electrical signal will stop. That is, the user can interrupt the sound output by tapping, touching, or other means while the human-computer interaction device is outputting, so that the human-computer interaction device switches to a sound perception mode or a vibration perception mode.

[0192] The control unit 210 can determine the operating state of the human-computer interaction device based on the content indicated by the first electrical signal and the second electrical signal or the analysis result. For example, if the control unit 210 determines that the external vibration is caused by the user's touch or tapping based on the second electrical signal, and determines that the user needs voice interaction, then the control unit 210 determines that the human-computer interaction device is operating in the sound perception mode. Alternatively, if the control unit 210 determines that the user has requested a song via voice based on the analysis result, then the control unit 210 determines that the human-computer interaction device is operating in the output mode and plays the corresponding song through the piezoelectric component 100. Furthermore, if the control unit 210 determines that no external feedback is needed based on the content indicated by the first electrical signal, such as when the user has ended the interaction, then the control unit 210 determines that the human-computer interaction device is operating in a standby mode or a low-power operating state. The standby mode can be either a vibration perception mode or a sound perception mode.

[0193] Furthermore, different persistent working modes can be adapted to different scenarios. In some embodiments, the sound perception mode can be selected as the persistent working mode during a specific time period (e.g., daytime) or a specific area, while the vibration perception mode can be selected as the persistent working mode during non-specific time periods (e.g., nighttime) or non-specific areas. In other embodiments, the sound perception mode can be selected as the persistent working mode within a preset time threshold range where no external feedback is required, and the vibration perception mode can be selected as the persistent working mode after the preset time threshold range is exceeded when no external feedback is required.

[0194] When the human-computer interaction device needs to switch to the sound perception mode, the control unit 210 controls the signal processing unit 221 and the analog-to-digital converter to switch to the active mode, and controls the controllable switch 240 to connect the second transmission circuit T2 and disconnect the fourth transmission circuit T4, so that the human-computer interaction device works in the sound perception mode. In the sound perception mode, the piezoelectric component 100 can generate a second electrical signal based on the user's voice deformation. The second electrical signal is transmitted to the analog-to-digital converter 222 through the second transmission circuit T2. The analog-to-digital converter 222 converts the second transmission circuit T2 into a digital signal. The signal processing unit 221 analyzes the converted second electrical signal to generate an analysis result, and sends it to the control unit 210 through the first sub-circuit T31.

[0195] When the human-machine interface device needs to switch to vibration sensing mode, the control unit 210 controls the signal processing unit 221 and the analog-to-digital conversion unit to switch to disabled mode, and controls the controllable switch 240 to disconnect the second transmission circuit T2 and connect the fourth transmission circuit T4, so that the human-machine interface device operates in vibration sensing mode. In vibration sensing mode, the piezoelectric component 100 can generate a second electrical signal based on the user's touch, tap, etc., and the second electrical signal is transmitted to the control unit 210 through the fourth transmission circuit T4.

[0196] When the human-machine interface device needs to switch to output mode, the control unit 210 controls the signal processing unit 221 and the adjustment component 230 to switch to active mode, and controls the controllable switch 240 to disconnect the second transmission circuit T2 and the fourth transmission circuit T4, so that the human-machine interface device works in output mode. In output mode, the control unit 210 can instruct the signal processing unit 221 to work through the first control command. The control signal processing unit 221 obtains the audio file from the external audio source module 600 or the built-in storage unit 250 according to the audio identifier, and parses the audio file into a first electrical signal and transmits it to the adjustment component 230. The control unit 210 can instruct the adjustment component 230 to work through the second control command. The output selection unit 232 of the adjustment component 230 divides the first electrical signal into sub-signals and outputs them to different piezoelectric components 100. The power adjustment unit 231 of the adjustment component 230 adjusts the power of the sub-signals to adapt to the output requirements of the piezoelectric components 100, thereby driving one or more piezoelectric components 100 to vibrate.

[0197] In one example, when the human-machine interface device is in a standby mode (such as vibration sensing mode), the user taps the car window twice. The piezoelectric component 100 at the window position responds to the tapping vibration and generates a second electrical signal. The control unit 210 receives the second electrical signal through the fourth transmission circuit T4 and determines that the user has an interaction request. It then wakes up the recognition output component 220 and controls the recognition output component 220 to drive the piezoelectric component 100 to emit sound, thus switching the human-machine interface device to output mode. The piezoelectric component 100 can emit voice commands such as "What do you need help with?" After the sound output ends, the control unit 210 switches the human-machine interface device to auditory sensing mode to receive the user's voice commands. Based on this, the recognition output component 220 receives the second electrical signal and parses it to determine that the user has issued the voice command "Open the car door". The control unit 210 controls the identification output component 220 to drive the piezoelectric component 100 to emit sound, informing the user "Please enter Morse code for identity verification", and switches the human-machine interaction device to vibration sensing mode so as to receive the Morse code entered by the user. The control unit 210 can transmit the user's input tap signal to the vehicle terminal so that the vehicle terminal can determine whether the door needs to be opened.
