[0002] For mobile vehicles, including cars and other types of vehicles, it may sometimes be necessary for occupants inside the vehicle to communicate with people outside. However, because the interior and exterior of a mobile vehicle are usually acoustically and physically isolated from each other, occupants may open windows or doors to communicate with people outside. This can lead to problems such as excessive temperature differences between the inside and outside of the vehicle, or discomfort in inclement weather conditions such as rain or snow.

[0003] Furthermore, autonomous vehicles are currently under development, and in the future, there may be situations where communication with people outside the vehicle is necessary. However, conducting such communication by opening windows or doors could pose potential safety risks.

Figure 10 This is a schematic diagram of the control of a mobile vehicle in an external communication system for a mobile vehicle according to an exemplary embodiment of the present disclosure.

[0050] This disclosure enables communication between the mobile vehicle 10 and external objects (including people); ensures that the components used for such communication do not adversely affect the appearance design elements of the mobile vehicle 10; and ensures ease of use by maintaining communication quality.

[0051] Therefore, in one exemplary embodiment of this disclosure, an external communication system for a mobile vehicle may include: a sound generator 100 having a first vibration panel 110, which is combined with an external panel 11 of the mobile vehicle 10, and generates sound through the first vibration panel 110; and a sound receiver 200 having a second vibration panel 210, which is combined with an external panel 11 of the mobile vehicle 10 and spaced apart from the first vibration panel 110, and receives sound through the second vibration panel 210.

[0052] In one exemplary embodiment of this disclosure, the mobile vehicle 10 may be a vehicle, but is not limited thereto, and may cover various types of transport vehicles.

[0053] The mobile vehicle 10 is provided with an external panel 11 for isolating and shielding the internal and external environments of the mobile vehicle 10. The external panel 11 may include various components, such as padding, doors, and trim, and may be an exposed portion. A sound generator 100 and a sound receiver 200 may be located on the exterior of the mobile vehicle 10, including components such as padding, doors, and trim. The sound generator 100 and the sound receiver 200 may be arranged adjacent to each other to enable sound-based communication with external objects. In an exemplary embodiment of this disclosure, the command entity 20 may be a person, and the mounting positions of the sound generator 100 and the sound receiver 200 may be determined based on the height of the person's face when standing. For example, the sound generator 100 and the sound receiver 200 may be located on the A-pillar, B-pillar, or C-pillar of the vehicle.

[0054] In one exemplary embodiment of this disclosure, the sound generator 100 may be a speaker, and the sound receiver 200 may be a microphone.

[0055] Here, the sound generator 100 and the sound receiver 200 can be positioned vertically, with the sound generator 100 located above the sound receiver 200.

[0056] By positioning the sound generator 100 at the top, the sound produced by the sound generator 100 can be projected more widely. Furthermore, by positioning the sound receiver 200 at the bottom, it can be brought closer to the user's mouth, thereby improving the accuracy of speech recognition. Moreover, by positioning the sound generator 100 and the sound receiver 200 longitudinally spaced apart, it is easier to maintain sufficient distance between them. This configuration helps reduce howling or feedback noise caused by sound entering the sound receiver 200 while sound is being transmitted directly to the user.

[0057] In one exemplary embodiment of this disclosure, the sound generator 100 includes a first vibration panel 110 through which the sound generator 100 generates sound.

[0058] The color of the first vibration panel 110 can be the same as or different from the outer panel 11 of the mobile vehicle 10, thus serving as an element of appearance design.

[0059] Furthermore, the first vibrating panel 110 can be designed to facilitate the transmission of sound characteristics and can be made of materials such as aluminum or titanium in the form of a thin film. Alternatively, the first vibrating panel 110 can be made of plastic or reinforced plastic and can be made of the same material as the outer panel 11.

[0060] The sound generator 100 can generate sound through a first vibrating panel 110, which forms part of the external panel 11 of the mobile vehicle 10, thereby integrating design elements with sound transmission functionality and reducing the required installation space.

[0061] In one exemplary embodiment of this disclosure, such as Figure 3 As shown, the sound generator 100 includes a first coil 131, a first permanent magnet 132, and a first suspension member 133. The first suspension member 133 is disposed below the first vibration panel 110, supports the first vibration panel 110, and the first coil 131, which vibrates due to the first permanent magnet 132, can be connected to the first vibration panel 110 to generate sound.

[0062] The sound generator 100 serves as a loudspeaker that converts electrical signals into sound, and may include a first coil 131, a first permanent magnet 132, a first suspension member 133, and a first vibration panel 110. A first plate 134 may be disposed below the first vibration panel 110 to fix the first permanent magnet 132, and both the first plate 134 and the first suspension member 133 may be fixed to a part of the vehicle body below the first vibration panel 110.

[0063] The first suspension 133 elastically supports the first vibrating panel 110, thereby maintaining its position while allowing the first vibrating panel 110 to vibrate. The first suspension 133 may include a spring, but other materials capable of providing elastic support for the first vibrating panel 110 may also be used.

[0064] A first permanent magnet 132 forms a magnetic field around a first coil 131, which drives the first coil 131. An alternating current (AC) can be applied to the first coil 131, and the application of the current can be controlled by a controller 300. The electrical signal emitted by the controller 300 for generating sound can be amplified by an amplifier. With this configuration, the first permanent magnet 132 forms a magnetic field around the first coil 131, causing the first coil 131 (and consequently the first vibrating panel 110) to vibrate through interaction with this magnetic field.

[0065] In addition, such as Figure 4 As shown, a first receiving portion 12 for accommodating a sound generator 100 may be disposed on an outer panel 11, and a first vibration panel 110 may be configured to be coupled to the first receiving portion 12.

[0066] That is, the first receiving portion 12 may be formed as a hole penetrating a portion of the outer panel 11, and the first vibrating panel 110 may be configured to mate with the inner contour shape of the first receiving portion 12. In one exemplary embodiment of this disclosure, the first receiving portion 12 and the first vibrating panel 110 are described as having a rectangular shape; however, various other shapes may also be adopted, including polygonal or circular shapes.

[0067] Here, a first coupling 120 is disposed between the first vibrating panel 110 and the first receiving portion 12. The first coupling 120 may be elastically deformable, thereby allowing the first vibrating panel 110 to be disposed within the first receiving portion 12. The first coupling 120 may be made of rubber material and configured to surround the outer edge portion of the first vibrating panel 110 and the inner edge portion of the first receiving portion 12, thereby forming an airtight seal between them. Furthermore, since the first coupling 120 is elastically deformable, it enables the first vibrating panel 110 to vibrate to generate sound and seals the gap between the first vibrating panel 110 and the outer panel 11, thereby preventing foreign objects or moisture from entering the interior.

[0068] In one exemplary embodiment of this disclosure, the sound receiver 200 includes a second vibration panel 210 configured to convert acoustic energy generated by a user into mechanical vibrations for sound reception.

[0069] In another exemplary embodiment of this disclosure, the sound receiver 200 may utilize a second vibration panel 210 as a design element, which may also serve as an indicator that the user's voice has been recognized.

[0070] In a sound receiver 200 according to an exemplary embodiment of the present disclosure, the second vibration panel 210 may be the same color as or different from the outer panel 11 of the mobile vehicle 10, and may function as an external design element. Furthermore, the structure of the second vibration panel 210 may be used to convert the acoustic energy of sound waves generated by the user into mechanical vibrations, and may be made of aluminum or titanium in the form of a thin film. Alternatively, the second vibration panel 210 may be made of plastic, reinforced plastic, or the same material as the outer panel 11.

[0071] The sound receiver 200 can receive sound through a second vibration panel 210 that forms part of the external panel 11 of the mobile vehicle 10, thereby integrating design elements with sound transmission functionality and reducing the required installation space.

[0072] In one exemplary embodiment of this disclosure, such as Figure 5 As shown, the sound receiver 200 includes a second coil 231, a second permanent magnet 232, and a second suspension member 233. The second suspension member 233 supports the second vibration panel 210. When the second coil 231 vibrates together with the second vibration panel 210, the second permanent magnet 232 induces a voltage signal in the second coil 231, thereby realizing sound reception.

[0073] The sound receiver 200 is configured to be used as a microphone that converts sound waves into electrical signals, and may include a second coil 231, a second permanent magnet 232, a second suspension 233, and a second vibration panel 210.

[0074] The second plate 234 located below the second vibration panel 210 can be configured to fix the second permanent magnet 232, and both the second plate 234 and the second suspension member 233 can be fixed to the vehicle body on the inner side of the second vibration panel 210.

[0075] The second suspension 233 elastically supports the second vibrating panel 210, maintaining its position while allowing the second vibrating panel 210 to vibrate. The second suspension 233 may be made of a spring, or other materials capable of providing elastic support for the second vibrating panel 210 may be used.

[0076] The second vibration panel 210 vibrates in response to sound waves generated by external user sounds, and the second coil 231 connected to the second vibration panel 210 also vibrates with the second vibration panel 210.

[0077] The second permanent magnet 232, positioned below the second vibrating panel 210, forms a magnetic field around the second coil 231. When the second coil 231 vibrates within the magnetic field of the second permanent magnet 232, an induced voltage is generated. This induced voltage is received as an output signal by a controller 300 operatively connected to the second coil 231 and converted into an audio signal corresponding to the received sound. This output signal can be amplified or mixed by an amplifier or mixer. In this example, the sound receiver 200 can be configured to receive sound generated by the vibration of the second vibrating panel 210 and the second coil 231 in response to sound waves. The second coil 231 can generate a voltage signal by interacting with the magnetic field of the second permanent magnet 232.

[0078] In addition, such as Figure 6 As shown, the second receiving portion 13 may be formed on a portion of the outer panel 11 for receiving the sound receiver 200, and the second vibration panel 210 may be configured to be coupled to the second receiving portion 13.

[0079] The second receiving portion 13 may be formed as a through-hole in the outer panel 11, and the second vibrating panel 210 may be configured to mate with the inner contour of the second receiving portion 13. In one exemplary embodiment of this disclosure, the second receiving portion 13 and the second vibrating panel 210 may be formed as rectangles; however, various shapes, including polygons or circles, may also be used. Furthermore, the second receiving portion 13 may be disposed near the first receiving portion 12.

[0080] A second coupling 220 may be disposed between the second vibrating panel 210 and the second receiving portion 13. The second coupling 220 may be made of an elastically deformable material to allow the second vibrating panel 210 to be disposed within the second receiving portion 13. The second coupling 220 may be made of a rubber material and may be configured to surround the outer periphery of the second vibrating panel 210 and the inner and outer peripheries of the second receiving portion 13, thereby sealing the interface between the second vibrating panel 210 and the second receiving portion 13. Furthermore, due to its elastic deformability, the second coupling 220 both allows the second vibrating panel 210 to vibrate to receive sound and seals the inner and outer sides of the second vibrating panel 210 to prevent the ingress of foreign objects or moisture.

[0081] In another exemplary embodiment of this disclosure, the sound receiver 200 may include an acoustic sensor 241, an output section 242, and an actuator 243.

[0082] like Figure 7As shown, when the acoustic sensor 241 detects sound, the output unit 242 can output the detected sound from the acoustic sensor 241 as a sound signal, and the actuator 243 connected to the second vibration panel 210 can cause the second vibration panel 210 to vibrate according to the sound signal received from the output unit 242. Since the second vibration panel itself does not have the function of a microphone or speaker, the output unit 242 may include a vibrating speaker with a vibrator connected to the back of the second vibration panel 210, so that it can function as both a microphone and a speaker.

[0083] That is, in the exemplary embodiment of this disclosure, the sound receiver 200 can detect sound through the acoustic sensor 241, convert the sound into an electrical signal, and the output unit 242 can amplify the electrical signal or remove noise from the electrical signal and output the electrical signal as a sound signal. The actuator 243 may include a small flat electromagnet combined with the second vibration panel 210 for generating vibration and responding to a control signal from the controller 300 operatively connected to the actuator 243 to cause the second vibration panel 210 to vibrate.

[0084] Therefore, in another exemplary embodiment of the sound receiver 200, sound can be received by the acoustic sensor 241 and the output unit 242, and the actuator 243 can be driven according to the signal corresponding to the received sound to cause the second vibration panel 210 to vibrate, thereby notifying the outside that sound is being received.

[0085] In addition, such as Figure 8 As shown, the sound receiver 200 may also include an operation unit 250 configured for sound reception.

[0086] The operating unit 250 can be a button or touch switch and can be located on the external panel 11 of the mobile vehicle 10 near the sound receiver 200.

[0087] The operation unit 250 can be configured to prevent feedback noise or howling when the sound generator 100 and the sound receiver 200 are operating simultaneously. When the operation unit 250 is activated, the sound generated by the sound generator 100 is limited, and the sound can be received by the sound receiver 200.

[0088] Therefore, when the operation unit 250 is operated directly from outside the mobile vehicle 10, the user's intentions can be reflected, and sound can be received by the sound receiver 200, thereby realizing voice transmission. Furthermore, since the sound generator 100's sound generation is limited, the accuracy of communication is also improved.

[0089] Here, the voice input received by the voice receiver 200 can come from inside the mobile vehicle 10, the control center that controls the mobile vehicle 10, or the mobile vehicle 10 itself. Furthermore, when it is mentioned that the voice generator 100 is restricted during the operation of the operation unit 250, this includes muting and reducing the volume.

[0090] In addition, such as Figure 9 As shown, the sound generator 100 may further include a first indicator 140 that lights up when a sound is generated, and the sound receiver 200 may further include a second indicator 260 that lights up when a sound is received.

[0091] The first indicator 140 and the second indicator 260 can be implemented using LEDs. The first indicator 140 can be disposed on the external panel 11 of the mobile vehicle 10 near the sound generator 100, and the second indicator 260 can be disposed on the external panel 11 of the mobile vehicle 10 near the sound receiver 200.

[0092] Furthermore, when the sound generator 100 generates sound, the first indicator 140 can light up and display an image resembling a speaker. Similarly, when the sound receiver 200 receives sound, the second indicator 260 can light up and display an image resembling a microphone.

[0093] Therefore, when the sound generator 100 generates sound, the first indicator 140 lights up, and when the sound receiver 200 receives sound, the second indicator 260 lights up, enabling the user to externally identify the timing of the voice output and reception, thereby achieving smoother communication.

[0094] In addition, under the control of the controller 300, the volume of the sound generated by the sound generator 100 and the sensitivity of the sound received by the sound receiver 200 can be controlled.

[0095] The volume of the sound generated by the sound generator 100 and the sensitivity of the sound received by the sound receiver 200 can be adjusted directly within the mobile vehicle 10, or they can be automatically adjusted based on the control of the controller 300.

[0096] The controller 300 can be used not only to control the sound generator 100 and the sound receiver 200, but also to control the overall operation of the mobile vehicle 10. It can be configured to control the various components of the mobile vehicle 10 based on data obtained from various sensors installed on the mobile vehicle 10 or data obtained through communication with external devices.

[0097] The controller 300 can adjust the volume of the sound generator 100 and / or the sensitivity of the sound receiver 200 based on commands input from inside the mobile vehicle 10 or commands received through the sound receiver 200. That is, when there are occupants inside the mobile vehicle 10, they can directly adjust the volume of the sound generator 100 and / or the sensitivity of the sound receiver 200 to improve communication quality with users outside the mobile vehicle 10. Furthermore, when a user outside the mobile vehicle 10 issues a voice command through the sound receiver 200, the controller 300 can adjust the volume of the sound generator 100 and / or the sensitivity of the sound receiver 200. When the mobile vehicle 10 is in autonomous driving mode, the control center responsible for the operation of the mobile vehicle 10 can adjust the volume of the sound generator 100 and / or the sensitivity of the sound receiver 200.

[0098] Furthermore, when the controller 300 receives an input from the position recognition unit 400 indicating that the mobile vehicle 10 is located in a preset noise generation area, the controller 300 may increase the volume of the sound generator 100 or the sensitivity of the sound receiver 200.

[0099] The location identification unit 400 may include various methods for identifying the current location of the mobile vehicle 10, such as a Global Positioning System (GPS) and communication with a control center. The controller 300 determines whether the mobile vehicle 10 is located in a preset noise-generating area based on the location information received from the location identification unit 400. The noise-generating area may include, for example, a city center area or a construction site, and may be defined based on various factors including at least one of the following: surrounding environment, population density, and regional characteristics.

[0100] Therefore, when the controller 300 determines that the mobile vehicle 10 has entered the noise generation area, it can increase the output sound level of the sound generator 100 and the sound receiving sensitivity of the sound receiver 200, thereby ensuring effective communication between the user located outside the mobile vehicle 10 and the mobile vehicle 10 itself, even in a high-noise environment.

[0101] Furthermore, the controller 300 can identify the noise level near the mobile vehicle 10 and further adjust the output sound level of the sound generator 100 and the receiving sensitivity of the sound receiver 200 based on the identified noise level. The noise level around the mobile vehicle 10 can be determined based on external sound input received through the sound receiver 200, or various other methods can be used to determine the ambient noise level.

[0102] When the controller 300 receives an input from the position identification unit 400 indicating that the mobile vehicle 10 has entered a severe weather area, it can increase the output sound level of the sound generator 100 and the sound receiving sensitivity of the sound receiver 200.

[0103] Severe weather areas may include environmental factors such as rain or snow. Therefore, when the location identification unit 400 determines that the mobile vehicle 10 has entered a severe weather area, the controller 300 can increase the output sound level of the sound generator 100 and the sound receiving sensitivity of the sound receiver 200, thereby ensuring effective communication between the user located outside the mobile vehicle 10 and the mobile vehicle 10 itself, even in the presence of rain, snow, and noise.

[0104] Additionally, the mobile vehicle 10 can be configured to perform autonomous driving and may be equipped with a detection unit 14 for detecting nearby objects. The detection unit 14 may be implemented using a camera or various other detection methods, such as lasers or lidar, to detect objects around the mobile vehicle 10.

[0105] like Figure 10 As shown, when the controller 300 detects the command entity 20 communicating with the mobile vehicle 10 through the detection unit 14, the controller 300 can move the mobile vehicle 10 so that the sound generator 100 and the sound receiver 200 face the command entity 20.

[0106] Since the sound generator 100 and the sound receiver 200 are fixed in position on the mobile vehicle 10, the closer the sound generator 100 and the sound receiver 200 are to the command entity 20 (i.e., the user), the higher the accuracy of sound transmission and reception.

[0107] Therefore, the controller 300 can identify the location of the user, who is the instruction entity 20, based on the image information received by the detection unit 14. Then, the controller 300 can instruct the mobile vehicle 10 to bring the sound generator 100 and the sound receiver 200 closer to the user.

[0108] Furthermore, when the mobile vehicle 10 is unable to move toward the command entity 20, the sound generator 100 can emit a guiding sound to prompt the command entity 20 to approach the sound generator 100 and the sound receiver 200.

[0109] That is, when the mobile vehicle 10 moves toward the command entity 20 (i.e., the user), the mobile vehicle 10 may encounter driving difficulties due to road conditions or the presence of surrounding obstacles. In this case, the sound generator 100 can emit a guiding sound to prompt the user to move toward the mobile vehicle 10.

[0110] Furthermore, the mobile vehicle 10 may be equipped with a display unit 15 for transmitting information to the outside. When the detection unit 14 identifies the command entity 20 located near the mobile vehicle 10, the positions of the sound generator 100 and the sound receiver 200 can be displayed on the display unit 15.

[0111] The display unit 15 can be installed on the exterior of the mobile vehicle 10 (including the roof) and display visual information on its screen to help the user identify the mobile vehicle 10. In addition, by displaying information on the display unit 15, the user can be prompted to identify the location of the sound generator 100 and the sound receiver 200 on the external panel 11 of the mobile vehicle 10.

[0112] Therefore, the instruction entity 20 can be directed to the sound generator 100 and the sound receiver 200 disposed on the mobile vehicle 10, thereby enabling accurate transmission and reception of communication sound and improving the usability of the mobile vehicle 10.

[0113] According to the external communication system of the mobile vehicle disclosed herein, a user inside the mobile vehicle 10 or a control center operating the mobile vehicle 10 can communicate with a command entity 20, which may include personnel located outside the mobile vehicle 10.

[0114] Furthermore, the sound generator 100 and sound receiver 200 used for voice communication can be integrated with the external panel 11 of the mobile vehicle 10, or they can be designed as part of the external panel 11 of the mobile vehicle 10, thereby maintaining the appearance design of the vehicle.

[0115] In addition, by ensuring high-quality voice communication, the system helps prevent user discomfort caused by poor call quality.

[0116] Although specific embodiments of this disclosure have been illustrated and described, those skilled in the art should understand that various modifications and changes can be made without departing from the technical spirit of this disclosure.
