detailed description

Hereinafter, preferred embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

As mentioned above, in the prior art, data communication is performed through Bluetooth communication, and smart devices are charged through a USB interface. Neither Bluetooth connection nor USB charging can trigger the arousal of APP.

The present disclosure proposes that when a user inserts a smart device into a fixed component such as a card slot of the voice interaction module and responsively docks with the USB of the voice interaction module, the voice interaction module sends an APP arousal signal to the smart device via the USB interface. In other words, the physical contact between the smart device and the voice interaction module is used as the trigger condition to evoke the APP on the smart device.

As a result, the user's manual operation of evoking the APP on the smart device is reduced, the operation control is more convenient, and the user experience is significantly improved.

Fig. 1 is a schematic block diagram of a voice interaction module 100 according to a first embodiment of the present disclosure.

As shown in FIG. 1, the voice interaction module 100 may include a chip 110, a USB interface 130, and a microphone 140.

The USB interface 130 is suitable for docking with the smart device 10. Here, the smart device 10 may be, for example, a mobile phone or the like.

The microphone 140 is used to acquire the voice uttered by the user.

The chip 110 is connected to the USB interface 130. The chip 110 may be, for example, a micro control unit (MCU).

The chip 110 sends the voice acquired by the microphone 140 to the smart device 10 so as to be processed by the APP on the smart device 10. The APP may be an APP associated with the voice interaction module 100, or may be an APP designated in advance or on-site in real time.

In response to the USB interface 130 transitioning from the state not docked with the smart device 10 to the state docked with the smart device 10, the chip 110 sends an APP awakening signal to the smart device 10 via the USB interface 130 to awaken the APP on the smart device 10.

As a result, convenient APP arousal is realized, the device operation process is simplified, and the user experience is significantly improved.

The voice interaction method and voice interaction apparatus executed on the smart device 10 according to the present disclosure are described below with reference to FIGS. 2 and 3.

FIG. 2 is a schematic flowchart of a voice interaction method that can be executed on the smart device 10 according to the present disclosure.

FIG. 3 is a schematic block diagram of a voice interaction device 30 according to the present disclosure.

In step S210, the user can insert or place the smart device 10 into a fixed component such as a card slot of the voice interaction module 100, so that the smart device 10 is docked with the USB interface 130 of the voice interaction module 100.

As described above, at this time, the voice interaction module 100 will send an APP awakening signal to the smart device 10 via the USB interface 130.

In step S220, for example, the wake-up signal receiving device 320 of the voice interaction device 30 shown in FIG. 3 may receive the APP wake-up signal via the USB interface 130.

In step S230, the wake-up device 330 shown in FIG. 3, for example, wakes up the APP in response to receiving the APP wake-up signal.

In step S240, for example, the data communication device 340 shown in FIG. 3 performs data communication with the voice interaction module 100 based on the APP.

As a result, the user does not need to manually perform an arousal operation on the smart device 10, that is, the APP can be automatically aroused on the smart device 10, thereby starting data communication between the smart device 10 and the voice interaction module 100 based on the APP.

Here, the data communication may include two-way data communication between the voice interaction module 100 and the smart device 10. For example, the data communication device 340 can receive the voice acquired by the voice interaction module 100. On the other hand, the data communication device 340 can also send control instructions and/or audio data to the voice interaction module 100.

As shown in FIG. 3, the voice interaction device 30 may further include a processing device 350. The processing device 350 can analyze and process the voice acquired by the voice interaction module 100 and uploaded to the smart device 10.

The data communication device 340 may send a control instruction and/or audio data to the voice interaction module 100 based on the analysis and processing result of the processing device 350.

For example, the user makes a navigation request by voice. The microphone 140 can collect the user's voice. The voice interaction module 100 uploads the voice to the smart device 10. The processing device 350 of the smart device 10 analyzes and processes the voice, and after understanding the meaning it represents, obtains the response navigation audio information. Then, the navigation audio information is sent to the voice interaction module 100, and then the voice interaction module 100's own player or a speaker/speaker device associated with it broadcasts the navigation voice.

Or, the user makes a request for playing music, for example, by voice. The microphone 140 can collect the user's voice. The voice interaction module 100 uploads the voice to the smart device 10. The processing device 350 of the smart device 10 analyzes and processes the voice, and after understanding the meaning it represents, sends the audio data of the music to the voice interaction module 100. Then, the player of the voice interaction module 100 itself or a speaker/speaker device associated with the voice interaction module 100 plays the corresponding music.

Alternatively, the user sends a control request for the voice interaction module 100 itself or other devices associated with it through voice. The processing device 350 of the smart device 10 analyzes and processes the voice, and after understanding its meaning, sends a control instruction to the voice interaction module 100, so as to realize the control of the response.

In addition, the data communication between the voice interaction module 100 and the smart device 10 can be achieved through Bluetooth communication, or through the USB interface 130.

On the other hand, the voice interaction module 100 is often connected to a power source, such as a vehicle power source, and has a charging function. When the smart device 10 is docked with the USB interface 130 of the voice interaction module 100, the voice interaction module 100 will charge the smart device 10.

Generally, the USB interface 130 is used for charging. In some cases, the wireless charging module can also be used for charging.

There are currently many USB charging modes, such as USB BC 1.2 charging downstream port (CDP) mode, smart charging (SMART CHARGE) mode, QC3.0 fast charging mode, PE fast charging mode, etc.

Among the above charging modes, except that the CDP mode can support simultaneous USB data communication during charging, the other modes do not support simultaneous USB data communication during charging.

In order to avoid conflicts between data communication and charging, the smart device 10 can adopt the following methods.

In the case where the voice interaction module 100 charges the smart device 10 through the USB interface 130, data communication with the voice interaction module 100 may be performed through Bluetooth communication.

In the case that the voice interaction module 100 charges the smart device 10 through a wireless charging method, data communication can be performed with the voice interaction module 100 via the USB interface 130.

When the voice interaction module 100 stops charging the smart device 10 through the USB interface 130, data communication can be performed with the voice interaction module 100 through the USB interface 130.

When the voice interaction module 100 supports data communication with the smart device 10 via the USB interface 130, and the smart device 10 is charged through the USB interface 130, data communication with the voice interaction module 100 can be performed via the USB interface 130 .

The voice interaction module according to the second embodiment of the present disclosure will be described below with reference to FIG. 4.

As shown in FIG. 4, in addition to the chip 110, the USB interface 130, and the microphone 140 described above, the voice interaction module 200 may also include a USB charging control chip 120, a signal transmission module 150, a wireless charging module 160, and an overvoltage Protection module (OVP) 170. It should be understood that the voice interaction module 200 may only include any one or a combination of any multiple of the USB charging control chip 120, the signal transmitting module 150, the wireless charging module 160, and the overvoltage protection module (OVP) 170.

The above descriptions of the voice interaction module 100 with reference to FIG. 1 can be applied to the voice interaction module 200.

The USB charging control chip 120 is connected to the USB interface 130 and a power source, and is used to charge the smart device 10 through the USB interface 130. An overvoltage protection module (OVP) 170 can be connected between the USB charging control chip 120 and the power supply to perform overvoltage protection.

The connection state or charging mode of the USB charging control chip 120 may have two states. In the first state, the chip 110 and the smart device 10 are allowed to communicate data via the USB interface 130. The second state can support a high-efficiency charging mode, but does not support data communication between the chip 110 and the smart device 10 via the USB interface 130. Those skilled in the art should understand that multiple methods can be used to switch between the two states of the USB charging control chip 120. As an example, two examples that can be used to switch between these two states will be described below with reference to FIGS. 5 and 6.

It is possible to switch to the first state when data communication is required, for example, in response to a data communication request. After the data communication ends, it switches to the second state. As a result, the flexibility of operation control is increased, and the user experience can be significantly improved.

For example, when the smart device 10 is inserted, or when the smart device 10 is just docked with the USB interface 130, it can be switched to the first state to realize the data interaction between the voice interaction module and the smart device 10 via the USB interface 130. For example, the voice interaction module may send a wake-up signal to the smart device 10 via the USB interface 130 to wake up the APP.

Specifically, in response to the USB interface 130 being switched from the state not docked with the smart device 10 to the state docked with the smart device 10, the connection state or charging mode of the USB charging control chip 120 may be set to allow the chip 110 to be connected to the smart device 10. The first state of data communication via the USB interface 130. Thus, the chip 110 can send an APP awakening signal to the smart device 10 through the USB interface 130.

For example, the connection state between the smart device 10 and the USB interface 130 can be determined by detecting the current signal at the USB interface 130. After detecting the change of the connection state at the USB interface 130, the chip 110 may send a control signal to switch the connection state or charging mode of the USB charging control chip 120.

In this case, the chip 110 may send an APP awakening signal to the smart device 10 via the USB interface 130 to awaken the APP on the smart device 10.

In this way, the automatic awakening of the APP can be realized without requiring the user to operate on the smart device 10.

On the other hand, after sending the APP awakening signal via the USB interface 130, the connection state or the charging mode of the USB charging control chip 120 can be set to be able to charge and not support the second data communication between the chip 110 and the smart device 10 via the USB interface 130. Two states to achieve high efficiency charging. The above setting can be executed after sending the APP awakening signal, or after receiving the APP awakening response signal returned by the smart device 10.

In addition, after the APP on the smart device 10 is awakened, it can also respond to, for example, a data communication request between the APP on the smart device 10 and the voice interaction module 100, such as uploading voice collected by the voice interaction module 100, and the smart device 10 Send music data to the voice interaction module 100, and set the connection state or charging mode of the USB charging control chip 120 to a state that allows the chip 110 to communicate with the smart device 10 via the USB interface. Thus, the chip 110 can perform data communication with the smart device 10 via the USB interface 130.

In response to the end of the data communication, the connection state or charging mode of the USB charging control chip 120 can be reset to a second state where charging is possible without supporting the chip 110 and the smart device 10 for data communication via the USB interface 130.

In addition, after the smart device 10 is removed from the voice interaction module 110, or in other words, when the USB interface changes from the state of being docked with the smart device 10 to the state of not being docked with the smart device 10, the USB charging control chip 120 can be The connection state or charging mode is set to a state that allows the chip 110 and the smart device 10 to perform data communication via the USB interface. In this way, when the smart device 10 is inserted next time, data communication can be performed.

On the other hand, when the power of the smart device 10 is fully charged, the connection state or charging mode of the USB charging control chip 120 can be set to a state that allows the chip 110 and the smart device 10 to communicate data via the USB interface 130. For example, by detecting the current signal at the USB interface 130, it can be determined whether the power of the smart device 10 is fully charged. When it is detected that the power of the smart device 10 is full, the chip 110 may send a control signal to switch the connection state or the charging mode of the USB charging control chip 120.

Thus, the voice interaction module 100 according to the present disclosure can switch between the state of supporting data communication and the state of high-efficiency charging, which expands the flexibility of operation control and can significantly improve user experience.

The voice interaction module 100 may be, for example, a vehicle-mounted voice interaction module, and the power supply may be a vehicle-mounted power supply.

In addition, the chip 110 may include a digital-to-analog conversion (ADC) module 112 for performing digital-to-analog conversion on the current signal detected from the USB interface 130 to obtain a digital detection signal. The chip 110 can determine the docking state between the smart device 10 and the USB interface 130 and the power state of the smart device 10 based on the digital detection signal.

The voice interaction module 100 may also include a Bluetooth module 115. The Bluetooth module 115 may be independent of the chip 110, or may be included on the chip 110 as shown in FIG. 4. When the APP has been awakened, data communication can be performed with the APP on the smart device 10 through Bluetooth communication.

In addition, a wireless charging module 160 may also be provided. In this way, the smart device 10 can be wirelessly charged while the chip 110 performs data communication with the smart device 10 via the USB interface 130.

The signal transmission module 150 may also be connected to the chip 110. The chip 110 converts audio data received from the smart device 10 into a frequency modulation signal or an amplitude modulation signal. The signal transmitting module 150 sends the FM signal or AM signal to nearby radios, such as car radios, so as to play corresponding audio through the speakers of the radio or the car audio. For example, the smart device 10 may, for example, send music data to the voice interaction module 200 in response to an instruction issued by the user through voice. The signal transmitting module 140 transmits a frequency modulation signal or an amplitude modulation signal corresponding to the music data to the car radio. After the car radio receives the FM signal or the AM signal, it can play music through the car audio equipment.

The

voice interaction modules

300 and 400 according to the third and fourth embodiments of the present disclosure are described below with reference to FIGS. 5 and 6.

In the description of the third embodiment and the fourth embodiment, the focus is on the realization of the switching mode of the above-mentioned connection state or charging mode of the USB charging control chip 120. The foregoing descriptions of the voice interaction module 100 and the voice interaction module 200 with reference to FIGS. 1 and 4 can be applied to the voice interaction module 300 and the voice interaction module 400.

FIG. 5 is a schematic block diagram of a voice interaction module 300 according to the third embodiment of the present disclosure.

In the third embodiment, the interaction mode of the USB charging control chip 120 is switched to realize the switching between the first state and the second state described above.

Here, for example, a USB charging control chip 120 that supports two charging modes can be selected.

The first charging mode corresponds to the above-mentioned first state, and the support chip 110 and the smart device 10 perform data communication via the USB interface 130. In addition, the first charging mode can support lower current charging.

The second charging mode corresponds to the aforementioned second state, and supports a higher charging current than the first charging mode, but generally does not support data communication via the USB interface 130.

For example, the USB charging control chip 120 may be a CW3046 chip. Correspondingly, the first charging mode is a charging downstream port (CDP) mode, and the second charging mode is a smart charging mode.

The chip 110 may send a control signal to the USB charging control chip 120. The USB charging control chip 120 can switch between the above two charging modes in response to the control signal.

The timing of the mode switching may be the same as the voice interaction module 100 described above with reference to FIG. 1.
