FIG. 1 is a schematic block diagram of a vehicle according to one embodiment of the present application. As shown in fig. 1, the vehicle 10 includes: a detection device 110, a voice interaction device 120 and a sound production device 130. The detection device 110 is used for detecting an environment outside the vehicle, and may include at least one of a voice detection module 111, a vibration detection module 112, and a distance detection module 113. The speech detection module 111 is configured to detect speech and generate speech data. The vibration detection module 112 is configured to detect vibrations and generate vibration data. The distance detection module 113 is configured to detect distances and generate distance data. The voice interaction device 120 is connected to the detection device 110, and generates an audio signal based on the voice data, the vibration data, and/or the distance data acquired from the detection device 110. The sound generating device 130 is connected to the voice interaction device 120 and generates sound under the excitation of the audio signal.

According to the embodiment of the application, the voice interaction device is respectively connected with the detection device and the sound generation device for detecting the environment outside the vehicle, so that the voice interaction device can interact with the person outside the vehicle based on the voice data, the vibration data and/or the distance data detected by the detection device, and the vehicle 10 is endowed with a function of interacting with the person outside the vehicle (hereinafter, referred to as external interaction).

In some embodiments of the present application, the detection device 110 includes a distance detection module 113. The distance detection module 113 may include at least one Time of flight (TOF) sensor. Illustratively, TOF sensors are elements that perform ranging based on TOF. TOF sensors typically require the use of some artificial light source for distance measurement, which can calculate the distance between an object and the TOF sensor by measuring the "time of flight" of ultrasonic, microwave, light, etc. signals between the emitter and the reflector. The TOF sensor may be a TOF sensor that measures distance by infrared or laser light, or other sensors.

Illustratively, the vehicle 10 identifies a distance between a person outside the vehicle approaching the vehicle 10 and the vehicle 10 using a TOF sensor, and activates the voice interaction device 120 upon determining that the distance between the person outside the vehicle and the vehicle 10 is less than a preset distance and a time less than the preset distance is greater than a preset time, based on the distance data acquired by the TOF sensor. After the voice interaction device 120 is activated, an audio signal may be sent to the sound generation device 130 to stimulate the sound generation thereof. Wherein, the audio signal can be determined according to the interaction process of the person outside the vehicle and the vehicle. For example, after the voice interaction device 120 is turned on, an audio signal is generated, and the audio signal may indicate at least one of the following information: voice interaction has been turned on, asked to speak a request to the person outside the vehicle, or to introduce the vehicle 10 to the person outside the vehicle, etc. Through the distance detection module 130, the vehicle 10 may interact with external people, and may further have the ability to actively accost external people.

It should be understood that the preset distance and the preset time may be set by a user or a manufacturer without departing from the teachings of the present application, which is not limited in this application.

Fig. 2 is an exemplary block diagram of a vehicle 10 according to some embodiments of the present application, fig. 3 is an exemplary diagram of locations of a transmitter 1331 and a receiver 1332 of a distance detection module 113 inside a B-pillar 141 according to some embodiments of the present application, fig. 4a is an exemplary diagram of locations of a transmitter 1331 and a receiver 1332 of a distance detection module 113 on a rear view mirror 143 according to some embodiments of the present application, and fig. 4B is an exemplary diagram of locations of a transmitter 1331 and a receiver 1332 of a distance detection module 113 on a rear view mirror 143 according to other embodiments of the present application.

In some embodiments of the present application, the distance detection module 113 is provided to at least one of a B-pillar 141 (see fig. 3) between front and rear seats of a cabin of the vehicle 10, a window glass frame 142 covering the B-pillar 141, and a rear view mirror 143. For example, referring to fig. 2 and 3, the distance detection module 113 is mounted on a circuit board (e.g., the second circuit board 152 mentioned below) inside the B-pillar, and the mounting of the distance detection module 113 is more flexible due to a larger space inside the B-pillar. The distance detection module 113 generally includes a transmitter 1331 and a receiver 1332, the transmitter 1331 is used for emitting laser to detect the distance of the object, and the receiver 1332 is used for receiving the optical signal after the laser is reflected by the object. The distance between the object and the distance detection module 113 can be calculated based on the time of flight of the laser.

Illustratively, there are two types of construction of the vehicle 10 in some technologies, one having a windowpane frame and the other not. For a vehicle 10 having a window frame 142, for example, as shown in fig. 2, the distance detection module 113 may be mounted on the window frame 142, may be mounted inside the B-pillar, or may be mounted on a rear view mirror 143 outside the vehicle. If the distance detection module 113 is installed inside the B pillar, the window glass frame 142 of the vehicle 10 may be made of a material having a higher transparency in order to ensure the detection function of the distance detection module 113. For a vehicle without the window frame 142, the distance detection module 113 may be mounted inside the B-pillar and may also be mounted on a rear view mirror 143 outside the vehicle. Due to the higher transparency of the glass, the detection light waves emitted by the distance detection module 113, such as a TOF distance sensor, are more favorably propagated outwards.

In some embodiments of the present application, the distance detection module 113 includes at least one bio-sensor disposed around the rear view mirror 143, for example, on a decorative cover of the rear view mirror or a base cover of the rear view mirror. The mounting positions of the transmitter 1131 and the receiver 1132 of the distance detection module 113 on the rear view mirror 143 may be as shown in fig. 4a and 4 b. Alternatively, as shown in FIG. 4a, the transmitter 1131 and the receiver 1132 may be mounted on the front surface of the housing of the rearview mirror to detect whether a person is approaching the side of the vehicle 10. Alternatively, considering that the outside mirror 143 is normally folded when the vehicle 10 is turned off, the transmitter 1131 and the receiver 1132 may be mounted on the back of the housing of the outside mirror 143, so that the folded mirror can monitor whether there is a person approaching the side of the vehicle 10, and the vehicle 10 can actively wake up the voice interaction module in the vehicle in a dormant state, so that the vehicle 10 has the capability of communicating with the person outside the vehicle.

It should be understood that the distance detection module 113 may be mounted in other locations without departing from the teachings of the present application, and the present application is not limited thereto.

As one example, referring to fig. 2, the detection device 110 of the vehicle 10 may further include a voice detection module 111 and/or a vibration detection module 112. The voice detection module 111 may include a component with a voice collecting function, such as a microphone, for detecting voice outside the vehicle to generate voice data. The vibration detection module 112 may include components having a vibration detection function, such as a vibration sensor, for detecting vibrations to generate vibration data.

The vibration detection module 112 is exemplarily described below.

In some embodiments of the present application, the vibration detection module 112 is disposed on at least one of a door panel 144, a hood 145, a trunk lid 146, a front bumper 147, and a rear bumper 148 of the vehicle such that an occupant outside the vehicle can interact with the vehicle 10 by tapping on the same. The vibration detection module 112 may include one or more vibration sensors. Since the lead of the chip of the vibration sensor is short, the vibration sensor can be mounted on a circuit board to introduce electrical signals such as a power supply through the circuit board and to output the detected electrical signals to the outside.

As an example, the vibration detection module 112 may be mounted on a circuit board separately, and the circuit board may be mounted inside the door panel 144, inside the hood 145, or inside the trunk lid 146, inside the front bumper 147, inside the rear bumper 148, and so on.

As another example, referring to fig. 2, the vehicle 10 further includes a first circuit board 151 provided with a first Microcontroller (MCU), the first circuit board 151 being disposed inside the door panel 144. The vibration detection module 112 is connected to the first circuit board 151, and is connected to the voice interaction device 120 through the first microcontroller. Wherein the first microcontroller may be configured to recognize the vibration data and determine whether to send the vibration data to the voice interaction device. For example, if the vehicle-exterior person taps around the vibration detection module 112 according to the designated tapping pattern, the first microcontroller may send vibration data to the voice interaction device 120 to activate the voice interaction device 120 after detecting that the tapping pattern of the vehicle-exterior person is the designated tapping pattern.

Alternatively, the first circuit board 151 is disposed in a door dry area inside the door panel 144 to reduce rainwater and the like from short-circuiting the first circuit board 151 and the like.

Alternatively, the first microcontroller may also be used to control the vehicle door. In other words, the vibration detection Module 112 may be integrated with a Door Control Module (DCM) in some technologies and then disposed in the Door panel 144.

It should be understood that the vibration detection module 112 may take other configurations without departing from the teachings of the present application, and the present application is not limited thereto.

After the exemplary description of the vibration detection module 112 is completed, the voice detection module 111 is exemplarily described below.

In some embodiments of the present application, the voice detection module 111 may include a plurality of microphones. The plurality of microphones may constitute one or more microphone arrays. The microphone array may pick up audio signals of a person speaking outside the vehicle. The microphone array can be used for eliminating external noise, improving the signal-to-noise ratio of the voice outside the automobile and further improving the voice recognition rate. In addition, according to the decibel level of the voice outside the vehicle received by the microphones and the acoustic loss in the environment, the vehicle 10 can determine the distance between the sound source and the vehicle 10 according to the voice data, and can also recognize the position of the sound source according to the voice data of the microphones, so that sound field positioning is performed, the sound position of the person outside the vehicle is confirmed, and further more services are provided for the vehicle 10.

Alternatively, the voice detection module 111 is provided to at least one of a B-pillar 141 of the vehicle, a window glass frame 142 covering the B-pillar 141, and a rear view mirror 143. As an example, fig. 5 is a diagram of an example of a location of the speech detection module 111 inside a B-pillar according to some embodiments of the present application. Referring to fig. 5, the voice detection module 111 may be mounted on the second circuit board 152 inside the B-pillar 141, and the distance detection module 113 may be more flexibly mounted due to the larger space inside the B-pillar 141. As another example, a plurality of microphones are provided around the rear view mirror 143, for example, on a decorative cover of the rear view mirror or a base cover of the rear view mirror. Fig. 6 is an example diagram of a location of the voice detection module 111 on the rear view mirror 143 according to some embodiments of the present application. The rearview mirror 143 is close to the primary and secondary driving positions, and can better detect the interaction behavior of the main outside-vehicle personnel such as drivers.

It should be understood that the voice detection module 111 may be mounted in other locations without departing from the teachings of the present application, and the present application is not limited thereto.

Alternatively, referring to fig. 5 and 6, multiple microphones may be mounted on the same device of vehicle 10 or may be mounted on different devices of vehicle 10. The distance between each other is typically large when multiple microphones are mounted to different components of the vehicle 10. When any two microphones of the plurality of microphones are provided on the same device as the vehicle 10, the distance d (e.g., horizontal pitch) between any two microphones is greater than 30mm. By increasing the distance between the microphones, the noise suppression and other capabilities of the microphone array are improved.

In some embodiments of the present application, the microphone of the vehicle 10 may be waterproofed.

As an example, a waterproof film is attached to the surface of each microphone to make the microphone waterproof, thereby improving the service life of the microphone. The waterproof membrane can be made of sound-transmitting waterproof materials so as to reduce sound loss in the sound transmission process and reduce the damage of external water vapor to the microphone.

As another example, fig. 7 is a structural example view of an opening inside a B-pillar for mounting a voice detection module 111 according to some embodiments of the present application. As shown in fig. 6, the B-pillar 141 is provided with at least one opening 1411 extending from the surface of the B-pillar 141 to the inside of the B-pillar 141, the bottom of the opening 1411 is higher than the top of the opening 1411 relative to the bottom of the vehicle, and the microphone is arranged in the opening 1411, so that in rainy days and the like, even if part of rainwater falls outside the microphone, the amount of rainwater entering the microphone can be reduced because the sound receiving hole and the like of the microphone face downward, thereby reducing the damage of the rainwater to the microphone in rainy days and the like.

It should be understood that the microphone may also be waterproofed by other means without departing from the teachings of the present application, and the present application is not limited thereto.

Alternatively, the voice detection module 111 and the distance detection module 113 may be mounted on the same device. Illustratively, fig. 8 is a diagram of an example of the location of the speech detection module 111 and the distance detection module 113 inside a B-pillar according to some embodiments of the present application. As shown in fig. 8, the voice detection module 111 and the distance detection module 113 may be commonly connected to the same circuit board (e.g., the second circuit board 152). It should be understood that the voice detection module 111 and the distance detection module 113 may be mounted on different devices, and the present application is not limited thereto.

It should be appreciated that the vehicle 10 may also be provided without the distance detection module 113, and instead with the voice detection module 111 and/or the vibration detection module 112, without departing from the teachings of the present application, which is not limited in this application.

After completing the exemplary description of the voice detection module 111, the following describes the sound emitting device 130.

In some exemplary embodiments of the present application, the sound emitting device 130 may include at least one sound emitting module, which may be a speaker, a panel sound emitting module, or the like, that emits sound outwards when being excited by the audio signal of the voice interaction device 120.

For ease of understanding, the following description will be exemplified by a panel sound module.

The inventors have found that the loudspeaker can be used for sound production outside the vehicle, but it is not effective. In particular, because the speaker must have waterproof, dustproof, anticorrosion, high and low temperature resistance, etc. when used outside the vehicle, it is a great challenge for some coil type magnetic speakers in the technology. The cone diaphragm of the coil loudspeaker is difficult to have waterproof, dustproof and anticorrosion capabilities, and a built-in magnet of the cone diaphragm cannot work in a high-temperature environment. However, the above capabilities are typically those that are required to be available in an off-board work environment. In addition, the sound field of some speakers in the art is angled, and often in areas beyond the angle of the sound field, very low sound volume or sound dead zones are formed. This also has an impact on the interaction between the vehicle 10 and the person outside the vehicle. In view of this, some embodiments of the present application use a panel sound module as a sound emitting device. Illustratively, the panel sound module may be a piezoelectric panel sound module, which may include a piezoelectric ceramic speaker. Fig. 9 is a schematic diagram of a piezoelectric ceramic speaker according to some embodiments of the present application. The piezoceramic speaker may include an electrode pad 211 configured to receive an excitation voltage from a drive circuit. The electrode pads 211 may be a pair of positive and negative electrode pads. The piezoceramic speaker may further include a piezoceramic 212 configured to expand or contract laterally or longitudinally under the influence of an excitation voltage received through the electrode pads 211. The excitation voltage may be a high frequency square wave with alternating polarity, so that piezoelectric ceramic 212 will mechanically deform, i.e., elongate or contract, under the influence of the alternating polarity square wave. In addition, piezoelectric ceramic 212 may be a transversely or longitudinally polarized piezoelectric ceramic 212, such that a transverse or longitudinal mechanical deformation is generated under the action of an excitation voltage. The piezoelectric ceramic speaker may further include a vibration plate 213 attached to the piezoelectric ceramic 212 and generating vibration according to extension or contraction of the piezoelectric ceramic 212. In this way, the piezoelectric ceramic speaker converts an input excitation voltage into vibration, thereby emitting voice. The vibration plate 213 may be attached to a device such as the door panel 144 to vibrate the device such as the door panel 144. The piezoceramic speaker may further include a vibration pad 214 located between the vibration plate 213 and the door panel 144 or the like. Illustratively, the vibration pad 214 may be a double-sided tape for bonding the vibration plate 213 and the door panel 144. Further, in some embodiments, a piezoceramic speaker may include a plurality of piezoceramic 212 and corresponding pairs of electrode pads 211. For example, one piezoelectric ceramic 212 may be disposed on each of upper and lower sides of the vibration plate 213, and both may be extended or contracted in opposite directions by the respective electrode pads 211, thereby further enhancing the vibration effect. The sound is generated outwards through the panel sound generating module, so that the sound generating sound field of the vehicle 10 is wider.

In one example of the present application, the panel sound emission module may be provided to at least one of a door panel 144, a hood 145, a trunk lid 146, a roof panel, a chassis (not shown), a rear view mirror 143, a front bumper 147, and a rear bumper 148 of a vehicle.

For ease of understanding, the manner in which the panel sound module is mounted on the chassis is illustrated below. Fig. 10a is a schematic view of the mounting location of the panel sound module 131 on the chassis 149 according to some embodiments of the present application. Fig. 10b, 10c, and 10d are schematic cross-sectional views of the vehicle chassis 149, bottom plate 1491, and panel sound emitting module 131, according to some embodiments of the present application.

As shown in fig. 10a, 4 panel sound modules 131 can be mounted on the chassis 149, wherein 2 panel sound modules 131 are located on the front side of the chassis 149, and the other 2 panel sound modules 131 are located on the rear side of the chassis 149.

As an example, as shown in fig. 10b, a bottom plate 1491 is mounted on the ground-near side of the chassis 149 by a fixing device such as a rivet 1492, the bottom plate 1491 may be a flat plate made of plastic or a flat plate made of metal, and the panel sound module 131 may be a piezoelectric ceramic speaker, which may have a structure as shown in fig. 9. The piezoelectric ceramic speaker is fixed to the bottom plate 1491 by a double-sided tape (i.e., a vibration pad 214) for bonding the vibration plate 213 and the door panel 144. When the piezoelectric ceramic loudspeaker vibrates under the excitation of the excitation signal, the bottom plate 1491 is driven to vibrate, and then the surrounding air is driven to vibrate to produce sound outwards.

As another example, as shown in fig. 10c, the side of the chassis 149 close to the ground may be provided with a bottom plate 1491, and the bottom plate 1491 may be a cylindrical structure made of plastic or metal and having at least one hollow cavity in the middle. The column structure may be a cylinder structure, a square column structure, an inverted circular truncated cone structure (i.e., a bowl-shaped structure), etc., and is not limited herein. The panel sound module 131 may be a piezo ceramic speaker, which may be configured as shown in fig. 9. The piezoelectric ceramic speaker is fixed to the bottom plate 1491 by a double-sided tape (i.e., a vibration pad 214) for bonding the vibration plate 213 and the door panel 144. When the piezoelectric ceramic loudspeaker vibrates under the excitation of the excitation signal, the bottom plate 1491 is driven to vibrate, and then the surrounding air is driven to vibrate to produce sound outwards. In addition, because the panel sound module 131 is protected inside the bottom plate 1491, the damage of objects such as gravel to the panel sound module 131 during the driving of the vehicle can be reduced.

Optionally, on the basis of fig. 10c, as shown in fig. 10d, an opening 1493 may be disposed on the bottom plate 1491, so that air in the bottom plate 1491 can flow through the opening 1493 to the outside, thereby reducing the influence of environmental sealing on the vibration of the piezoelectric ceramic speaker, which further affects the sound-producing effect of the speaker. In addition, this trompil 1493 still can be used for flowing into the rainwater of the cavity between bottom plate 1491 and vehicle chassis 149 etc. and flow out, avoids rainwater to pile up and influences panel sound production module.

It should be understood that there is a gap between the chassis and the panel sound emitting module, and the height of the gap may be greater than 1mm or micron, which is not limited in this application.

It should be understood that the number and the installation positions of the panel sound modules 131 on the chassis 149 in fig. 10a are only exemplary, and in other embodiments, the number and the installation positions of the panel sound modules 131 on the chassis 149 may be adjusted as needed, which is not limited in the present application.

It should be understood that the panel sound module may be otherwise mounted to the chassis without departing from the teachings of the present application, and the present application is not limited thereto.

The above description is made for the way of mounting the panel sound-emitting module on the chassis, and the following description is made for the way of mounting the panel sound-emitting module on the rearview mirror.

In some embodiments of the present application, an independent sound production panel can be placed inside the exterior rearview mirror, and the piezoelectric ceramic plate is disposed on the sound production panel to form a panel sound production module, so that the vibration of the sound production panel is promoted through the vibration of the piezoelectric ceramic plate, and the air vibration is further promoted.

As an example, fig. 10e is a schematic structural view of a rear view mirror 143 in some technologies. The rear view mirror 143 includes a rear view mirror body 1431, a decorative cover 1432 of the rear view mirror, a rear view mirror lens 1433, a rear view mirror base cover 1434, a rear view mirror catch 1435, and a rotatable motor 1436. The mirror plate 1433 is connected to a rotatable motor 1436, and can be rotated laterally and/or longitudinally by the rotatable motor 1436. Fig. 10f is a schematic view of a rear view mirror 143 in some embodiments according to the present application. As shown in fig. 10f, the rear view mirror 143 is added with a motor fixing plate 1437 and a sound emitting panel 1438. The panel sound module 131 is adhered to one side or both sides of the sound panel 1438 by a double-sided adhesive tape, and the panel sound module 131 is connected to an external electrical signal through a wire 1439, a schematic top view thereof is shown in fig. 10g, and a schematic side view thereof can refer to fig. 10h, which is substantially the same as fig. 9.
