[0042] Reference Figure 1 , Figure 1 This is a schematic diagram of an electronic device provided in an embodiment of this application. The electronic device 10 includes: a control component 11, a touch sensing circuit 12, and a piezoelectric component 13; wherein,

[0043] The control component 11 is connected to the piezoelectric component 13 via the touch sensing circuit 12;

[0044] The piezoelectric component 13 is disposed on the target part of the target device, and the piezoelectric component 13 is configured to generate a first electrical signal in response to a tapping event acting on the target part;

[0045] The touch sensing circuit 12 is configured to receive the first electrical signal and modulate the first electrical signal into a second electrical signal for output to the control component 11;

[0046] The control component 11 is configured to generate a corresponding control command in response to the second electrical signal satisfying the control conditions.

[0047] In some embodiments, the piezoelectric component 13 may include at least one piezoelectric vibrator for converting mechanical stress (such as impact, vibration, etc.) into electrical energy (electrical signal). When the piezoelectric material in the piezoelectric vibrator is subjected to an external force, the charge distribution within it changes, thereby generating a potential difference on the material surface and forming an electrical signal.

[0048] The aforementioned tapping event refers to the interaction between an interactive object and an electronic device through a physical tapping action. In some implementation scenarios, this interaction behavior may involve the user tapping or striking the surface of the device with their hand, pen, or other object to trigger a specific function or operation. In some embodiments, the tapping event may be, but is not limited to, a single tap, continuous tapping, or tapping at a specific rhythm.

[0049] In some embodiments, the piezoelectric component 13 can be mounted on a target part of the target device to detect the user's tapping action. When the user taps, the piezoelectric vibrator component is subjected to mechanical stress, generates an electric charge, and converts it into the electrical signal to be analyzed. The control unit analyzes the electrical signal to be analyzed to complete the subsequent control process.

[0050] In some embodiments, the target device may be, but is not limited to, a vehicle, a smart home appliance, an access control device, a camera device, etc. Accordingly, the target component may be the housing of the target device or any component on the target device having a flat surface. For example, the target device may be a vehicle, and the target component may be the vehicle body, including but not limited to multiple body panels (e.g.), multiple interior trim pieces, and vehicle components connected to the body panels and / or interior trim pieces.

[0051] For example, a vehicle typically includes a frame, body, powertrain, and electrical system. The body and powertrain are both mounted on the frame, while the electrical system is mounted on both the body and frame. The body typically includes multiple body panels, multiple interior trim pieces, and multiple vehicle components. These body panels can be assembled to form the overall structure of the vehicle, such as a cabin or cargo compartment. Examples of body panels include doors, windows, hood, trunk lid, roof, front bumper, rear bumper, and fenders. Interior trim pieces are installed in the cabin and cargo compartment to enhance vehicle comfort and provide interfaces and equipment. Vehicle components are located within the cabin and cargo compartment and include seats, steering wheel, instrument panel, center console screen, armrest, and license plate.

[0052] Among them, vehicles include passenger vehicles including SUVs, buses, trucks, and various commercial vehicles; water vehicles including various boats and ships, and aircraft; and include 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 home appliances may include smart TVs, smart air conditioners, smart washing machines, smart speakers, smart rice cookers, cleaning equipment, smart body fat scales, lighting equipment, curtains, etc., without limitation.

[0053] In some embodiments, the process by which the touch sensing circuit 12 modulates the first electrical signal to obtain the second electrical signal includes at least one of the following: waveform transformation and amplitude identification.

[0054] In some embodiments, the signal state of the second electrical signal includes a first state and a second state, wherein the second electrical signal in the first state is different from the second electrical signal in the second state; the waveform transformation is used to transform a non-rectangular waveform into a rectangular waveform; the amplitude determination is used to output the second electrical signal in the first state or the second electrical signal in the second state based on the amplitude of the original signal.

[0055] The processing signal in the first state differs from that in the second state. For example, the processing signal in the first state and the processing signal in the second state differ significantly in characteristics such as voltage or current levels. Based on this, in the subsequent process of generating control commands based on the processing signals, the information carried in the original signal can be accurately interpreted by distinguishing between these two signal states, thereby determining the control commands to be generated.

[0056] In some implementation scenarios, the processing signal for the first state can be a processing signal at a first level, and the processing signal for the second state can be a processing signal at a second level. The first level can be greater than the second level, or vice versa.

[0057] In some embodiments, the touch sensing circuit 12 described above may also be configured to perform at least one of the following processes: amplification and voltage division.

[0058] In some embodiments, the control component 11 is further configured to extract signal features of the second electrical signal and generate control instructions corresponding to the signal features based on the signal features of the second electrical signal.

[0059] Among them, the aforementioned signal characteristics can be parameters that characterize the properties of electrical signals, such as frequency, intensity, pulse width, duration, and interval time.

[0060] In the above embodiments of this application, a first electrical signal is obtained by sensing a knocking event through a piezoelectric vibrator assembly, thereby realizing the input of information; and the signal is converted into a second electrical signal, and the corresponding control command is executed when the second electrical signal meets the control conditions, so that the user can input control commands even if he forgets to bring the control device.

[0061] Reference Figure 2 , Figure 2 This is a schematic diagram of an electronic device provided in an embodiment of this application. The touch sensing circuit 12 includes a first sensing circuit 121, and the piezoelectric component 13 includes at least one first piezoelectric vibrator 131; the control component 11 is connected to the at least one first piezoelectric vibrator 131 through the first sensing circuit 121.

[0062] In some embodiments, the touch sensing circuit 12 includes a first sensing circuit 121 connected to each of the first piezoelectric vibrators 131.

[0063] In other embodiments, the touch sensing circuit 12 includes at least one first sensing circuit 121, each of the first sensing circuits 121 being connected to at least one of the first piezoelectric vibrators 131.

[0064] The control component 11 can be configured with different signal transmission interfaces and connected to different first sensing circuits 121 through these different signal transmission interfaces.

[0065] In some embodiments, the first piezoelectric vibrator 131 may generate a first electrical signal in response to a striking event acting on the target, and modulate the first electrical signal into a second electrical signal through a first sensing circuit 121 connected to the first piezoelectric vibrator 131, and output it to the control component 11 through a corresponding signal transmission interface.

[0066] Reference Figure 3 , Figure 3 This is a schematic diagram of an electronic device provided in an embodiment of this application. The touch sensing circuit 12 further includes a second sensing circuit 122, and the piezoelectric component 13 includes at least one second piezoelectric vibrator 132. The at least one second piezoelectric vibrator 132 includes at least one independent piezoelectric vibrator, and the independent piezoelectric vibrator is located in an area on the target component where the first piezoelectric vibrator 131 is not disposed. The control component 11 is connected to the at least one second piezoelectric vibrator 132 through the second sensing circuit 122.

[0067] In some embodiments, the target component may include multiple regions, wherein the multiple regions may include a first region where the first piezoelectric vibrator 131 and the second piezoelectric vibrator 132 are present simultaneously, or a second region where the first piezoelectric vibrator 131 is absent but the second piezoelectric vibrator 132 is present.

[0068] like Figure 3 As shown, regions 1 and 2 are the first regions where both the first piezoelectric vibrator 131 and the second piezoelectric vibrator 132 exist simultaneously; region n is the second region where the first piezoelectric vibrator 131 does not exist, but the second piezoelectric vibrator 132 exists. It can be understood that the second piezoelectric vibrator 132 located in region n is an independent piezoelectric vibrator. There can be one or more second piezoelectric vibrators 132 located in region n, all of which are independent piezoelectric vibrators.

[0069] In some embodiments, in response to a tapping event acting on a first region of the target component, both the first piezoelectric vibrator 131 and the second piezoelectric vibrator 132 can generate a first electrical signal. The first piezoelectric vibrator 131 can modulate the first electrical signal into a second electrical signal through a first sensing circuit 121 connected to the first piezoelectric vibrator 131, and output it to the control component 11 through a corresponding signal transmission interface. The second piezoelectric vibrator 132 can modulate the first electrical signal into a second electrical signal through a first sensing circuit 122 connected to the first piezoelectric vibrator 132, and output it to the control component 11 through a corresponding signal transmission interface.

[0070] In some embodiments, the at least one first piezoelectric vibrator 131 has a different structure or properties than the at least one second piezoelectric vibrator 132.

[0071] The properties of the piezoelectric component can include the capacitance or dielectric constant of the piezoelectric element. For example, the capacitance or dielectric constant of the first piezoelectric element 11 is greater than that of the second piezoelectric element 22. Exemplarily, the first piezoelectric component 1 and the second piezoelectric component 2 can be manufactured using different piezoelectric materials. For example, the first piezoelectric element in the first piezoelectric component 1 can be made of a piezoelectric material with a capacitance greater than that of the second piezoelectric element in the second piezoelectric component 2. Alternatively, the first piezoelectric element in the first piezoelectric component 1 can be made of a piezoelectric material with a dielectric constant greater than that of the second piezoelectric element in the second piezoelectric component 2. In this way, when the same voltage is applied to the first piezoelectric component 1, it can generate a larger amplitude vibration, enabling the first piezoelectric component 1 to drive the target object to vibrate, thereby producing a clearer and higher-decibel sound from the target object.

[0072] The structure of the piezoelectric vibrator may include one or more of the following: the structure of the piezoelectric element, the area of ​​the piezoelectric element, the connection method between the piezoelectric assembly and the target object, and the area ratio of the electrode on the piezoelectric element. The piezoelectric element can be made of piezoelectric material, such as a piezoelectric ceramic sheet. For example, the number of stacked layers of the first piezoelectric element 11 is greater than the number of stacked layers of the second piezoelectric element 22. Exemplarily, the first piezoelectric assembly 1 and the second piezoelectric assembly 2 can be disposed on the target object with different connection methods. In some embodiments, the connection relationships between the first piezoelectric assembly 1 and the second piezoelectric assembly 2 and the target object are different. For example, a portion of the first piezoelectric assembly 1 can be connected to the target object to create a gap between the first piezoelectric assembly 1 and the target object, thereby allowing the vibration of the first piezoelectric assembly 1 to better drive the vibration of the target object. One side surface of the second piezoelectric assembly 2 can be completely connected to the target object, allowing the second piezoelectric assembly 2 to better undergo mechanical deformation with the vibration of the target object, thereby improving the accuracy of vibration detection by the second piezoelectric assembly 2.

[0073] In some embodiments, the operating states of the first piezoelectric vibrator may include a touch-sensing state, a sound-sensing state, and a sound-generating state; the operating states of the second piezoelectric vibrator may include a touch-sensing state. The two operating states differ. The vibration-sensing state is used to identify external vibrations of a first vibration type; the sound-sensing state is used to identify external speech vibrations of a second vibration type. For example, the first vibration type can be vibrations propagating through a solid or liquid medium, such as touching, tapping, or colliding; the second vibration type can be air wave vibrations generated by a sound source, such as speech information. The sound-generating state is used to drive the target component to which the piezoelectric vibrator is attached to vibrate, thereby generating sound.

[0074] In some embodiments, the inverse piezoelectric effect performance of the first piezoelectric oscillator is superior to that of the second piezoelectric oscillator. For example, under the same electric field, the first piezoelectric oscillator can produce greater deformation or displacement than the second piezoelectric oscillator; or, for example, the first piezoelectric oscillator has a higher energy conversion efficiency than the second piezoelectric oscillator in the process of converting electrical energy into mechanical energy.

[0075] Reference Figure 4 , Figure 4 This is a schematic diagram of an electronic device provided in an embodiment of this application. The control component 11 includes multiple signal transmission interfaces 110. At least one first piezoelectric vibrator 131 is connected to the control component 11 through different second signal transmission interfaces 112 (1121 and 1122 are shown exemplarily), and at least one second piezoelectric vibrator 132 is connected to the control component 11 through the same first signal transmission interface 111.

[0076] The plurality of signal transmission interfaces 110 may include a first signal transmission interface 111 and a second signal transmission interface 112.

[0077] In some embodiments, the number of first signal transmission interfaces 111 is one or more, and each first signal transmission interface 111 can be connected to a plurality of second piezoelectric vibrators 132. That is, each first signal transmission interface 111 can be connected to a group of second piezoelectric vibrators 132 and receive electrical signals generated from different regions of the target component. For example, as shown... Figure 4 As shown, the first signal transmission interface 111 is simultaneously connected to the second piezoelectric vibrator 132 located in region 1, the second piezoelectric vibrator 132 located in region 2, and the second piezoelectric vibrator 132 located in region n; it can be understood that... Figure 4 Only one first signal transmission interface 111 is shown in the figure, but the control component 11 may also include multiple first signal transmission interfaces 111.

[0078] In some embodiments, the number of second signal transmission interfaces 112 can be at least one, and different second signal transmission interfaces 112 are connected to different first piezoelectric vibrators 131. That is, one first piezoelectric vibrator 131 is connected to the control component 11 through one second signal transmission interface 112; the control component 11 is connected to a first piezoelectric vibrator 131 disposed in a region through one second signal transmission interface 112. For example, as... Figure 4 As shown, the second signal transmission interface 1121, which connects the first piezoelectric vibrator 131 in region 1 to the control component 11, is different from the second signal transmission interface 1122, which connects the first piezoelectric vibrator 131 in region 2 to the control component 11.

[0079] In some embodiments, the first sensing circuit 121 can be at least one ( Figure 4 (Not shown), different second signal transmission interfaces 112 can be connected to first piezoelectric vibrators 131 in different regions through different first sensing circuits 121. In some embodiments, the first sensing circuit 121 may include at least one sensing sub-circuit (…). Figure 4 (Not shown), different second signal transmission interfaces can be connected to the first piezoelectric vibrator 131 in different regions through different sensing sub-circuits in the first sensing circuit 121.

[0080] Reference Figure 5 , Figure 5 This is a schematic diagram of an electronic device provided in an embodiment of this application. The electronic device 10 further includes a switching assembly 14, which includes a first switching assembly 141 and / or a second switching assembly 142. The control terminals of the first switching assembly 141 and the second switching assembly 142 are connected to the control assembly 11. The first sensing circuit 121 is connected to at least one first piezoelectric vibrator 131 through the first switching assembly 141, and the second sensing circuit 122 is connected to at least one second piezoelectric vibrator 132 through the second switching assembly 142.

[0081] The control component 11 is also configured to control the on / off state of the first switch component 141 and / or the second switch component 142.

[0082] In some embodiments, the switching assembly 14 may include a first switching assembly 141, wherein the first sensing circuit 121 is connected to the at least one first piezoelectric vibrator 131 through the first switching assembly 141; and the second sensing circuit 122 is directly connected to the at least one second piezoelectric vibrator 132.

[0083] In some embodiments, the switching assembly 14 may include a second switching assembly 142, wherein the first sensing circuit 121 is directly connected to the at least one first piezoelectric vibrator 131; and the second sensing circuit 122 is connected to the at least one second piezoelectric vibrator 132 through the second switching assembly 142.

[0084] In some embodiments, the control component 11 is further configured to control the first switch component 141 to turn on, thereby enabling the touch sensing function of the first piezoelectric vibrator 131; or, to control the first switch component 141 to turn off, thereby turning off the touch sensing function of the first piezoelectric vibrator 131.

[0085] In some embodiments, the control component 11 is further configured to control the second switch component 142 to enable the touch sensing function of the second piezoelectric vibrator 132; or to control the first switch component 142 to disable the touch sensing function of the second piezoelectric vibrator 132.

[0086] It is understood that the states of the first switch assembly 141 and the second switch assembly 142 can be the same or different. Simultaneously, the control assembly 11 can switch the states of the first switch assembly 141 and the second switch assembly 142 simultaneously, or it can switch the states of the first switch assembly 141 and the second switch assembly 142 separately.

[0087] In some embodiments, the control component 11 is further configured to control the first switch component 141 and / or the second switch component 142 to disconnect in response to receiving the second electrical signal.

[0088] In some embodiments, after the control component 11 receives the second electrical signal, the control terminal of the first switch component 141 can be used to control the first switch component 141 to open, thereby disconnecting the first piezoelectric vibrator 131 from the control component 11 / first sensing circuit 121. At this time, the first piezoelectric vibrator 131 does not activate the touch sensing function.

[0089] In some embodiments, after the control component 11 receives the second electrical signal, the control terminal of the second switch component 142 can be used to control the second switch component 142 to open, thereby disconnecting the connection between the second piezoelectric vibrator 132 and the control component 11 / second sensing circuit 122. At this time, the second piezoelectric vibrator 132 does not activate the touch sensing function.

[0090] In some implementation scenarios, after the target object is tapped, the electronic device can respond to the tapping event by disabling the touch sensing function of the piezoelectric component. In some embodiments, after disabling the touch sensing function of the piezoelectric component, it can immediately switch to an auditory sensing state to realize the microphone (audio sensing function) function or switch to a sound-generating state to realize the sound-generating function.

[0091] In some embodiments, the control component 11 is further configured to determine the target element where the knocking event occurred based on the setting area of ​​the piezoelectric component 13 connected to the signal transmission interface 110 that receives the second electrical signal.

[0092] The signal transmission interface 110 that receives the second electrical signal may include the second signal transmission interface 112 and / or the first signal transmission interface 111.

[0093] In some embodiments, when the signal transmission interface 110 that receives the second electrical signal is the first signal transmission interface 111, since the first signal transmission interface 111 can receive the second electrical signal generated from different regions of the target component, it is necessary to further determine the signal transmission interface 112 that receives the second electrical signal.

[0094] In some embodiments, when a second electrical signal transmitted by the second signal transmission interface 112 is received, and a second electrical signal transmitted by the first signal transmission interface 111 is also received, the area where the tapping event occurs on the target component can be determined based on the setting area of ​​the second signal transmission interface 112 that received the second electrical signal.

[0095] For example, when the second signal transmission interface 112 receives the second electrical signal and is connected to region 1 of the target component, and receives the second electrical signal transmitted by the first signal transmission interface 111, it can be determined that the knocking event occurred in region 1 of the target component; when the second signal transmission interface 112 receives the second electrical signal and is connected to region 2 of the target component, and receives the second electrical signal transmitted by the first signal transmission interface 111, it can be determined that the knocking event occurred in region 2 of the target component, and so on.

[0096] In some embodiments, if a second electrical signal is received from the first signal transmission interface 111 but not from the second signal transmission interface 112, it can be determined that the impact event occurred in the region where the independent piezoelectric vibrator is located in the target component. For example, this could be region n in the above example.

[0097] In this embodiment, the control component 11 is further configured to determine the location of the tapping event on the target component based on the setting area of ​​the piezoelectric component 13 connected to the signal transmission interface 110 that receives the second electrical signal. Thus, through the touch sensing circuit, not only the reception time and signal strength of the second electrical signal can be obtained, but also the characteristic of the location of the tapping event on the target component can be determined. Therefore, during the process of generating corresponding control commands using the second electrical signal, the tapping event can be identified / classified from more dimensions of features, thereby achieving a precise understanding of the user's intent and generating corresponding control commands.

[0098] In keyless entry scenarios, the corresponding password to be verified can be identified through a tapping event. If the password meets the control conditions, the control command corresponding to the met control conditions is executed, which can be the vehicle unlocking command. Here, the password to be verified can include at least one character. By determining the area where the tapping event occurs on the target device, a more accurate character conversion process can be achieved from the dimension of the tapping event occurrence area. In addition, when the password to be verified includes multiple characters, the received second electrical signal can be divided into multiple sets of character electrical signals based on the different occurrence areas of the tapping event. In this way, the corresponding character conversion process can be performed for each set of character electrical signals, further improving the accuracy of character conversion and enhancing the security of keyless entry scenarios.

[0099] Reference Figure 6 , Figure 6 This is a schematic diagram of an electronic device provided in an embodiment of this application. The electronic device 10 further includes a sound perception circuit 15 and a sound acquisition component 16. The control component 11 is connected to the sound acquisition component 16 through the sound perception circuit 15. The sound perception circuit 15 is configured to acquire a third electrical signal generated by the sound acquisition component 16 and parse the third electrical signal into a fourth electrical signal for output to the control component 11.

[0100] In some embodiments, the sound acquisition component 16 may include at least one of the following: a microphone component, a piezoelectric vibrator in a sound perception state.

[0101] In some embodiments, the sound perception circuit 15 can receive a third electrical signal generated by the sound acquisition component 16, parse the third electrical signal into a fourth electrical signal, and output the fourth electrical signal to the control component 11.

[0102] In some embodiments, the process by which the sound perception circuit 15 resolves the third electrical signal into a fourth electrical signal may include at least one of the following: operational amplification, analog-to-digital conversion, or digital signal processing. The third electrical signal may be an analog signal, and the fourth electrical signal may be a digital signal.

[0103] In some embodiments, the control component 11 is configured to generate a corresponding control command in response to both the second electrical signal and the fourth electrical signal satisfying the control conditions.

[0104] The second electrical signal is generated by the tapping event, and the fourth electrical signal is generated by the ambient audio. The control conditions mentioned above may include preset tapping conditions that the tapping event needs to meet and preset audio conditions that the ambient audio needs to meet.

[0105] In some embodiments, the aforementioned tapping event may be generated by a user's tapping action on the target object, the aforementioned ambient audio may be the user's voice after tapping, and the fourth electrical signal may be the user's voice signal. Accordingly, the preset tapping condition may be a condition set for the user's tapping action, and the preset audio condition may be a condition set for the user's voice.

[0106] For example, the preset tapping condition can be three consecutive taps, and the preset audio condition can be a user issuing a voice command to "unlock". Unlocking is performed when the second electrical signal meets the preset tapping condition and the fourth electrical signal meets the preset audio condition.

[0107] Of course, corresponding control conditions can be set for different control commands. The above unlocking scenarios are only illustrative examples and are not intended to limit the implementation scenarios of this application.

[0108] Reference Figure 7 , Figure 7 This is a schematic diagram of an electronic device provided in an embodiment of this application. The sound acquisition component 16 includes the piezoelectric component 13; the piezoelectric component 13 is further configured to generate the third electrical signal in response to a sound event acting on the target component.

[0109] In some embodiments, the sound acquisition component 16 can be implemented by a piezoelectric vibrator in the piezoelectric component 13. Specifically, when implementing the sound perception function, the piezoelectric vibrator in the piezoelectric component 13 needs to be set to the sound perception state; that is, the piezoelectric vibrator in the piezoelectric component 13 used to implement the sound perception function needs to be connected to the sound perception circuit 15.

[0110] It should be noted that the piezoelectric component 13 may simultaneously include a piezoelectric vibrator in an auditory sensing state and a piezoelectric vibrator in other states (such as a touch sensing state or a sound-emitting state). Figure 7 (Not shown in the image).

[0111] In some embodiments, the sound event acting on the target component can be a user's voice event, and accordingly, the piezoelectric component 13 can generate a third electrical signal corresponding to the voice event.

[0112] In keyless entry scenarios, to improve security, it is necessary not only to detect knocking events and determine whether the corresponding preset knocking conditions are met, but also to detect sound events and determine whether preset audio conditions are met.

[0113] In this embodiment of the application, by reusing the piezoelectric component 13, the electronic device can realize both touch and sound sensing functions simultaneously without the need for additional hardware, which greatly reduces production costs and space occupation.

[0114] In some embodiments, sound events can be sensed first, followed by tapping events. In this case, the piezoelectric vibrator in the piezoelectric component 13 can first be in a sound sensing state, i.e., the piezoelectric vibrator is connected to the sound sensing circuit 15; then, it switches from the sound sensing state to the touch sensing state, i.e., the piezoelectric vibrator is connected to the touch sensing circuit 12. In other embodiments, tapping events can be sensed first, followed by sound events.

[0115] In other embodiments, sound event sensing and tapping event sensing can be performed simultaneously. In this case, a portion of the piezoelectric vibrators of the piezoelectric assembly 13 can be in a sound sensing state, that is, a portion of the piezoelectric vibrators are connected to the sound sensing circuit 15. At the same time, another portion of the piezoelectric vibrators of the piezoelectric assembly 13 can be in a touch sensing state, that is, another portion of the piezoelectric vibrators are connected to the touch sensing circuit 12.

[0116] Reference Figure 8 , Figure 8 This is a schematic diagram of an electronic device provided in an embodiment of this application. The electronic device 10 further includes a switch assembly 14, the control terminal of which is connected to the control assembly 11, and the execution terminal of which is connected to at least the touch sensing circuit 12 or the sound sensing circuit 15. The switch assembly is configured to connect or disconnect the touch sensing circuit 12 or the sound sensing circuit 15 in response to the control assembly 11.

[0117] In some embodiments, the switch assembly 14 is located between the sound acquisition assembly 16 and the sensing circuit (touch sensing circuit 12 or sound sensing circuit 15).

[0118] The control terminal of the switch assembly 14 is connected to the control assembly 11.

[0119] In some embodiments, the control component 11 is further configured to control the switch component 14 to enable the touch sensing circuit 12 to conduct with the sound acquisition component 16 (piezoelectric component 13), and to deactivate the sound sensing circuit 15 from the sound acquisition component 16 (piezoelectric component 13); the control component 11 is further configured to control the switch component 14 to enable the touch sensing circuit 12 to deactivate from the sound acquisition component 16 (piezoelectric component 13), and to enable the sound sensing circuit 15 to conduct with the sound acquisition component 16 (piezoelectric component 13). In some embodiments, at any given time, only one of the touch sensing circuit 12 and the sound sensing circuit 15 is connected to the sound acquisition component 16 (piezoelectric component 13).

[0120] In other embodiments, the on / off states between the touch sensing circuit 12 and the sound acquisition component 16 (piezoelectric component 13), and between the sound sensing circuit 15 and the sound acquisition component 16 (piezoelectric component 13), may be the same or different.

[0121] For example, such as Figure 8 As shown, the switch assembly 14 may include an execution terminal 1 and an execution terminal 2. The control assembly 11 can switch the touch sensing circuit 12 and the sound acquisition assembly 16 (piezoelectric assembly 13) on and off by switching the execution terminals 1 on and off. The control assembly 11 can also switch the sound sensing circuit 15 and the sound acquisition assembly 16 (piezoelectric assembly 13) on and off by switching the execution terminals 2 on and off.

[0122] In keyless entry scenarios, users can unlock devices in various ways, such as by performing preset tapping actions and / or speaking preset voice commands. The aforementioned switch component 14 allows the electronic components to flexibly switch between these different triggering methods. For example, when it is necessary to sense sound events, i.e., to listen to the user's voice commands, the control component 11 can use the switch component 14 to connect the sound sensing circuit 15 to the sound acquisition component 16 (piezoelectric component 13), while simultaneously disconnecting the touch sensing circuit 12 from the sound acquisition component 16. This allows the focus to be on capturing the user's voice signal. Conversely, when it is necessary to sense tapping events, i.e., to respond to the user's tapping action, the control component 11 can use the switch component 14 to connect the touch sensing circuit 12 to the sound acquisition component 16, while simultaneously disconnecting the sound sensing circuit 15. This allows the focus to be on detecting the user's tapping events.

[0123] Reference Figure 9 , Figure 9 This is a schematic diagram of an electronic device provided in an embodiment of this application. The common terminal 1401 of the switch assembly 14 is connected to the piezoelectric assembly 13, the first selection terminal 1402 of the switch assembly is connected to the touch sensing circuit 12, and the second selection terminal 1403 of the switch assembly is connected to the sound sensing circuit 15. The switch assembly 14 is configured to connect one of the touch sensing circuit 12 and the sound sensing circuit 15 and disconnect the other in response to the control assembly 11.

[0124] In some embodiments, the switch assembly 14 may include a common terminal 1401, a first selection terminal 1402, and a second selection terminal 1403.

[0125] In some embodiments, the switch assembly 14 responds to the control assembly 11 connecting the first selection terminal 1402 corresponding to the touch sensing circuit 12 with the common terminal 1401, thereby controlling the touch sensing circuit 12 to connect with the sound acquisition assembly 16 (piezoelectric assembly 13).

[0126] In some embodiments, the switching component 14 responds to the control component 11 by connecting the second selection terminal 1403 corresponding to the sound sensing circuit 15 with the common terminal 1401, thereby controlling the sound sensing circuit 15 to connect with the sound acquisition component 16 (piezoelectric component 13).

[0127] It should be noted that, in the current embodiment, when the touch sensing circuit 12 and the sound acquisition component 16 (piezoelectric component 13) are connected, the sound sensing circuit 15 and the sound acquisition component 16 (piezoelectric component 13) are disconnected; when the sound sensing circuit 15 and the sound acquisition component 16 (piezoelectric component 13) are connected, the touch sensing circuit 12 and the sound acquisition component 16 (piezoelectric component 13) are disconnected.

[0128] In a keyless entry scenario, the sound acquisition component 16 (piezoelectric component 13) can flexibly switch between touch sensing and sound sensing states by changing the selected terminal connected to the common terminal 1401, specifically by determining one of the selected terminals 1402 and 1403 connected to the common terminal 1401. For example, when sound events need to be sensed, the second selected terminal 1403 can be connected to the common terminal 1401; conversely, when tap events need to be sensed, the first selected terminal 1402 can be connected to the common terminal 1401.

[0129] Reference Figure 10 , Figure 10 This is a schematic diagram of an electronic device provided in an embodiment of this application. The switching assembly includes a third switching assembly 143 and / or a fourth switching assembly 144. The control terminals of the third switching assembly 143 and the fourth switching assembly 144 are connected to the control assembly 11. The touch sensing circuit 12 is connected to the piezoelectric assembly 13 through the third switching assembly 143. The sound sensing circuit 15 is connected to the piezoelectric assembly 13 through the fourth switching assembly 144.

[0130] The control component 11 is further configured to, in response to receiving the second electrical signal, control the third switch component 143 to open and control the fourth switch component 144 to open; or, in response to receiving the fourth electrical signal, control the third switch component 143 to open and control the fourth switch component 144 to open; or, in response to the fourth electrical signal not meeting the control conditions, control the third switch component 143 to open and control the fourth switch component 144 to open.

[0131] In some embodiments, the switching assembly 14 may include both a third switching assembly 143 and a fourth switching assembly 144. In this case, the control assembly 11 can control the on / off states of the third switching assembly 143 and the fourth switching assembly 144, respectively.

[0132] In some embodiments, the control component 11 may control the third switch component 143 to disconnect and control the fourth switch component 144 to connect in response to receiving the second electrical signal; at this time, the touch sensing function of the piezoelectric component 13 is turned off and the sound sensing function is turned on.

[0133] For example, in the control scenario described above, the tapping event can be sensed first, followed by the sound event. That is, after the tapping event is sensed by the piezoelectric component 13 in the touch sensing state, the control component 11 switches the piezoelectric component 13 from the touch sensing state to the sound sensing state, and then the user's sound event can be sensed by the piezoelectric component 13 in the sound sensing state.

[0134] In some embodiments, the control component 11 may also control the third switch component 143 to connect and the fourth switch component 144 to disconnect in response to receiving the fourth electrical signal; at this time, the sound sensing function of the piezoelectric component 13 is turned off and the touch sensing function is turned on. For example, in the above control scenario, sound events can be sensed first, followed by tapping events. That is, after sensing the user's sound event through the piezoelectric component 13 in the sound sensing state, the control component 11 switches the piezoelectric component 13 from the sound sensing state to the touch sensing state, and then the piezoelectric component 13 in the touch sensing state can sense tapping events.

[0135] In some embodiments, the control component 11 may also, in response to receiving a fourth electrical signal that does not meet the control conditions, control the third switch component 143 to connect and control the fourth switch component 144 to disconnect; at this time, the sound sensing function of the piezoelectric component 13 is turned off, and the touch sensing function is turned on. For example, in the above control scenario, sound event sensing can be performed first, and if the sound event does not meet the preset sound conditions, the tapping event sensing can be performed again.

[0136] Reference Figure 11 , Figure 11 This is a schematic diagram of an electronic device provided in an embodiment of this application, wherein the touch sensing circuit 12 includes a first sensing circuit 121, and the piezoelectric component 13 includes at least one first piezoelectric oscillator 131;

[0137] The electronic device 10 further includes a switching assembly 14, which includes a first switching assembly 141 and a fourth switching assembly 144. The control terminals of the first switching assembly 141 and the fourth switching assembly 144 are connected to the control assembly 11. The first sensing circuit 121 is connected to the at least one first piezoelectric vibrator 131 through the first switching assembly 141. The sound sensing circuit 15 is connected to the at least one first piezoelectric vibrator 131 through the fourth switching assembly 144.

[0138] The control component 11 is also configured to control the first switch component 141 to disconnect in response to receiving the second electrical signal, and at the same time control the fourth switch component 144 to connect.

[0139] In some embodiments, at least one first piezoelectric vibrator 131 can be connected to the first switch assembly 141 and the fourth switch assembly 144. That is, when the first sensing circuit 121 implements the touch sensing function, and when the sound sensing circuit 15 implements the sound sensing function, both are implemented by at least one first piezoelectric vibrator 131.

[0140] It is understandable that both the touch sensing function and the sound sensing function mentioned above use the piezoelectric effect of the first piezoelectric vibrator. In order to avoid mutual interference between the two functions, the same first piezoelectric vibrator can only realize one of the touch sensing function and the sound sensing function at the same time. That is to say, among the first switch assembly 141 and the fourth switch assembly 144, only one is on and the other is off.

[0141] In some embodiments, when multiple first piezoelectric vibrators exist, the first switching component 141 corresponding to a portion of the first piezoelectric vibrators can be turned on, while the fourth switching component 144 is turned off; simultaneously, the first switching component 141 corresponding to another portion of the first piezoelectric vibrators can be turned off, while the fourth switching component 144 is turned on. Thus, from an overall perspective, both touch sensing and sound sensing functions can be simultaneously realized.

[0142] In some embodiments, the control component 11 may, in response to receiving the second electrical signal, disconnect from the first switch component 141 and connect the fourth switch component 144; at this time, the touch sensing function of at least one first piezoelectric vibrator 131 is turned off, and the sound sensing function is turned on. For example, in the above control scenario, the sensing of a tapping event can be performed first, followed by the sensing of a sound event. That is, after sensing a tapping event through at least one first piezoelectric vibrator 131 in the touch sensing state, the control component 11 completes the switch from the touch sensing state to the sound sensing state of at least one first piezoelectric vibrator 131, thereby allowing the sensing of the user's sound events through at least one first piezoelectric vibrator 131 in the sound sensing state.

[0143] Reference Figure 12 , Figure 12 This is a schematic diagram of an electronic device provided in an embodiment of this application. The sound acquisition component 16 includes at least one microphone 161, the switching component includes a fifth switching component 145, the control terminal of the fifth switching component 145 is connected to the control component 11, and the sound perception circuit 15 is connected to the at least one microphone through the fifth switching component 145. The control component 11 is also configured to control the fifth switching component 145 to connect in response to receiving a second electrical signal.

[0144] In some embodiments, in the above Figure 8 Based on the corresponding embodiment, the sound acquisition component 16 can also be at least one microphone 161. The on / off state between the at least one microphone 161 and the sound perception circuit 15 can be controlled by the on / off state of the fifth switching component 145.

[0145] In some embodiments, since the sound sensing circuit 15 can sense sound events through at least one microphone 161, the control component 11 can control the switch component 14 to enable conduction between the touch sensing circuit 12 and the piezoelectric component 13. Simultaneously, by controlling the conduction of the fifth switch component 145, the control component 11 can control the conduction between at least one microphone 161 and the sound sensing circuit 15. Thus, the sensing of both tapping events and sound events can be achieved simultaneously.

[0146] Understandably, when both the perception of a knocking event and the perception of a sound event are realized simultaneously, the control component 11 can control the switch component 14 to disconnect the sound perception circuit 15 from the piezoelectric component 13 in order to avoid affecting the perception of the knocking event.

[0147] In other embodiments, the tapping event can be detected first, followed by the sound event. Thus, in the current embodiment, when detecting a tapping event, the control component 11 can control the switch component 14 to enable conduction between the touch sensing circuit 12 and the piezoelectric component 13, and simultaneously control the switch component 14 to disable the sound sensing circuit 15 and the piezoelectric component 13. At this time, the specific state of the fifth switch component 145 (whether on or off) does not directly and necessarily affect the direct detection process of the tapping event; energy saving by disabling the fifth switch component 145 can be considered. When the control component 11 receives the second electrical signal, sound event detection is required. Therefore, the control component 11 can control the switch component 14 to disable the touch sensing circuit 12 and the piezoelectric component 13; simultaneously, control the switch component 14 to enable conduction between the sound sensing circuit 15 and the piezoelectric component 13, and / or control the conduction of the fifth switch component 145 to control the conduction between at least one microphone 161 and the sound sensing circuit 15.

[0148] Reference Figure 13 , Figure 13 This is a schematic diagram of an electronic device provided in an embodiment of this application. The electronic device 10 further includes an audio playback circuit 17, and the control component 11 is connected to the piezoelectric component 13 through the audio playback circuit 17. The audio playback circuit 17 is also configured to output an audio signal to the piezoelectric component 13 in response to the control component 11. The piezoelectric component 13 is also configured to generate vibration in response to the audio signal.

[0149] It is understandable that when the piezoelectric component 13 is connected to the audio playback circuit 17 to achieve the sound generation function, it utilizes the inverse piezoelectric effect of the piezoelectric vibrator. However, when the piezoelectric component 13 is connected to the touch sensing circuit 12 to achieve the touch sensing function, it utilizes the piezoelectric effect of the piezoelectric vibrator. Therefore, in some embodiments, the same piezoelectric vibrator in the piezoelectric component 13 can only perform one of the touch sensing and sound generation functions at a time.

[0150] In some embodiments, the control component 11 may also be connected to the sound acquisition component 16 via the sound perception circuit 15.

[0151] Reference Figure 14 , Figure 14This is a schematic diagram of an electronic device provided in an embodiment of this application. The electronic device 10 further includes a switch assembly 14.

The switch assembly is configured to connect or disconnect the touch sensing circuit 12 or the audio playback circuit 17 in response to the control assembly 11.

[0152] In some embodiments, the switch assembly 14 is located between the piezoelectric assembly 13 and other circuits (touch sensing circuit 12, audio playback circuit 17, and sound sensing circuit 15).

It is understood that at any given time, only one of the touch sensing circuit 12 and the audio playback circuit 17 is connected to the piezoelectric component 13.

[0155] For example, such as Figure 14 As shown, the switch assembly 14 may include an execution terminal 1 and an execution terminal 3. The control assembly 11 can switch the touch sensing circuit 12 and the piezoelectric assembly 13 on and off by switching the execution terminals 1 on and off. The control assembly 11 can also switch the audio playback circuit 17 and the piezoelectric assembly 13 on and off by switching the execution terminals 3 on and off.

[0157] In some embodiments, the switch assembly 14 may include a common terminal 1401, a first selection terminal 1402, and a third selection terminal 1404.

[0158] In some embodiments, the switch assembly 14 responds to the control assembly 11 connecting the first selection terminal 1402 corresponding to the touch sensing circuit 12 with the common terminal 1401, thereby controlling the touch sensing circuit 12 to connect with the piezoelectric assembly 13.

[0159] In some embodiments, the switching component 14 controls the audio playback circuit 17 to be connected to the piezoelectric component 13 in response to the control component 11 connecting the third selection terminal 1404 corresponding to the audio playback circuit 17 to the common terminal 1401.

[0160] It should be noted that, in the current embodiment, when the touch sensing circuit 12 and the piezoelectric component 13 are connected, the audio playback circuit 17 and the piezoelectric component 13 are disconnected; when the audio playback circuit 17 and the piezoelectric component 13 are connected, the touch sensing circuit 12 and the piezoelectric component 13 are disconnected.

[0161] In some embodiments, the second selection terminal of the switch assembly is connected to the sound sensing circuit 15; the switch assembly is configured to connect one of the touch sensing circuit 12, the sound sensing circuit 15 and the audio playback circuit 17 and disconnect the other two in response to the control component 11.

[0163] It should be noted that, in the current embodiment, when the touch sensing circuit 12 and the piezoelectric component 13 are connected, the audio playback circuit 17 and the piezoelectric component 13 are disconnected, and the sound sensing circuit 15 and the piezoelectric component 13 are disconnected; when the audio playback circuit 17 and the piezoelectric component 13 are connected, the touch sensing circuit 12 and the piezoelectric component 13 are disconnected, and the sound sensing circuit 15 and the piezoelectric component 13 are disconnected; when the sound sensing circuit 15 and the piezoelectric component 13 are connected, the touch sensing circuit 12 and the piezoelectric component 13 are disconnected, and the audio playback circuit 17 and the piezoelectric component 13 are disconnected.

The switching assembly includes a sixth switching assembly 146 and either a third switching assembly 143 or a fourth switching assembly 144. The control terminals of the third switching assembly 143, the fourth switching assembly 144, and the sixth switching assembly 146 are all connected to the control assembly 11. The touch sensing circuit 12 is connected to the piezoelectric assembly 13 via the third switching assembly 143. The sound sensing circuit 15 is connected to the piezoelectric assembly 13 via the fourth switching assembly 144. The audio playback circuit 17 is connected to the piezoelectric assembly 13 via the sixth switching assembly 146. The audio playback circuit 17 is configured to output an audio signal to the piezoelectric assembly 13 in response to the control assembly 11, and to send a fifth electrical signal to the control assembly 11 after the audio signal output is completed.

[0165] The control component 11 is also configured to control the sixth switch component 146 to disconnect in response to the fifth electrical signal, while simultaneously controlling the third switch component 143 or the fourth switch component 144 to connect.

[0166] In some embodiments, the switch assembly 14 may simultaneously include a third switch assembly 143 and a sixth switch assembly 146. In this case, the control assembly 11 can control the on / off states of the third switch assembly 143 and the sixth switch assembly 146, respectively. In some embodiments, the switch assembly 14 may further include a fourth switch assembly 144.

[0167] In some embodiments, the sixth switch component 146 may initially be in a conducting state, at which time the control component 11 can output an audio signal to the piezoelectric component 13 through the audio playback circuit 17. In the above control scenario, the output audio signal may be a questioning voice to the user, or a guiding voice instructing the user to perform tapping input and / or voice input.

[0168] In some embodiments, after the audio signal output is completed, the audio playback circuit 17 sends a fifth electrical signal to the control component 11. This fifth electrical signal indicates that the audio signal output is complete. In response to the fifth electrical signal, the control component 11 controls the sixth switch component 146 to disconnect, and simultaneously controls the third switch component 143 or the fourth switch component 144 to connect. In the above control scenario, after the aforementioned guiding voice output, the perception of a tapping event and a sound event can be achieved by controlling the third switch component 143 and / or the fourth switch component 144 to connect.

The audio playback circuit 17 includes an audio processing component 171 and a power amplifier component 172. The control component 11 is connected to the audio processing component 171 and the power amplifier component 172. The audio processing component 171 is connected to the power amplifier component 172, and the power amplifier component 172 is connected to the piezoelectric component 13.

The control component 11 can be configured to control the operating state of the audio processing component 171, including an on state or an off state, wherein the off state includes a sleep state, a high-impedance state, and a mute state. In the aforementioned off state, the power amplifier component 172 does not output any audio voltage to the piezoelectric component 13.
