Description
Technical Field
[0001] This application relates to, but is not limited to, the field of electronic devices, and in particular to a vehicle. Background Technology
[0002] Vehicle audio systems are a crucial component in enhancing the driving and riding experience, and their performance directly impacts the listener's perception. As users' demands for audio quality increase, traditional audio systems face new challenges in terms of spatial arrangement, sound field distribution, and audio frequency band coverage.
[0003] Traditional audio systems typically consist of loudspeakers; however, loudspeakers have certain limitations in sound performance, especially in their response to high-frequency sounds. Utility Model Content
[0004] This application aims to provide a vehicle.
[0005] One embodiment of this application provides a vehicle, wherein the vehicle includes an audio system, the audio system including at least a first speaker and a first piezoelectric sound-generating component; wherein the first speaker is mounted on a first predetermined part of the vehicle, and the first piezoelectric sound-generating component is mounted on a second predetermined part of the vehicle; the first speaker is used to output an audio signal of a first frequency band of a target audio signal; the first piezoelectric sound-generating component is used to output an audio signal of a second frequency band of the target audio signal, the first frequency band and the second frequency band are different frequency bands. Thus, by combining the speaker and the piezoelectric sound-generating component to output audio signals of different frequency bands, the advantages of the speaker and the piezoelectric sound-generating component can be better utilized, improving the overall sound effect.
[0006] Another embodiment of this application provides a vehicle in which the target audio signal is a multi-channel audio signal. For the multi-channel audio signal, a combination of a loudspeaker and a piezoelectric sound-generating component is used to output audio signals of different frequency bands of a single channel, thereby improving the sound effect of the channel and enabling the audio signal of the channel to more accurately match its corresponding spatial position and frequency characteristics, thus enhancing the spatial sense and immersiveness of the stereo sound field.
[0007] Another embodiment of this application provides a vehicle in which the audio system further includes a second piezoelectric sound-generating component for outputting audio signals of at least a portion of the frequency bands of a second channel in the target audio signal, wherein the second channel includes at least one channel in the target audio signal. For multi-channel audio signals, by outputting a portion or all of the frequency bands of another channel through the second piezoelectric sound-generating component, the overall sound effect of the audio system is further improved by utilizing the fast response and high-frequency response characteristics of the piezoelectric sound-generating component.
[0008] Another embodiment of this application provides a vehicle in which a second piezoelectric sound-generating component is installed on one or more body panels such as the hood, front bumper, rear hood, rear bumper, left door, and right door.

[0009] Another embodiment of this application provides a vehicle in which the second piezoelectric sound-generating component includes at least two piezoelectric sound-generating components for outputting a full-frequency audio signal of a second channel. By having multiple piezoelectric sound-generating components collaboratively output a full-frequency audio signal of the same channel, higher power audio output can be achieved, enhancing sound penetration and clarity, and expanding the coverage of the sound field.
[0010] Another embodiment of this application provides a vehicle in which the audio system includes a second piezoelectric sound-generating component and a second loudspeaker. The combination of the loudspeaker and the piezoelectric sound-generating component outputs audio signals of a different frequency band of another channel, improving the sound effect of that channel. This allows the audio signal of that channel to more accurately match its corresponding spatial position and frequency characteristics, enhancing the spatial sense and immersiveness of the stereo sound field.
[0011] Another embodiment of this application provides a vehicle in which the audio system further includes a third speaker for outputting an audio signal of at least a portion of the frequency band of a third channel in the target audio signal, the third channel including at least one channel in the target audio signal. By introducing more speakers to cover more channels, a richer spatial sound effect is provided to the vehicle, further enhancing the spatial sense and immersiveness of the stereo sound field.
[0012] Another embodiment of this application provides a vehicle in which the audio system further includes a second speaker for outputting an audio signal of at least a portion of the frequency band of a second channel in the target audio signal, the second channel including at least one channel in the target audio signal. By introducing more speakers to cover more channels, a richer spatial sound effect is provided to the vehicle, further enhancing the spatial sense and immersiveness of the stereo sound field.
[0013] Another embodiment of this application provides a vehicle in which a first speaker is installed in one or more locations, such as inside the front grille, below the headlights, inside the rear grille, below the taillights, or in the chassis. Installing the speaker in a concealed location, such as at the front or bottom of the vehicle, ensures effective sound output while maintaining the consistency and aesthetics of the vehicle's exterior design.
[0014] Another embodiment of this application provides a vehicle in which a first piezoelectric sound-generating component is installed on one or more body panels, such as the hood, front bumper, rear hood, rear bumper, left door, and right door. By rationally setting the distribution position of the first piezoelectric sound-generating component on the body panels, the coverage range of the external sound field can be optimized, and the sound generation effect of the external sound field can be improved.

[0022] In order to gain a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.
[0023] Traditional audio systems are typically composed of loudspeakers, but loudspeakers have certain limitations in sound performance, especially in the response to high-frequency sounds.
[0024] Based on this, this application provides a vehicle including an audio system. The audio system includes at least a first speaker and a first piezoelectric sound-generating component. The combination of the speaker and the piezoelectric sound-generating component outputs audio signals of different frequency bands. For example, the speaker is responsible for the mid-low frequency part, and the piezoelectric sound-generating component is responsible for the high frequency part, thereby compensating for the shortcomings of traditional speakers in high frequency response and improving the high frequency sound effect of the vehicle audio system.
[0025] Figure 1This is a schematic diagram of a first optional component structure of the vehicle in an embodiment of this application, as shown below. Figure 1 As shown, the vehicle 100 includes at least an audio system 110, which includes at least a first speaker 111 and a first piezoelectric sound-generating component 112; wherein,
[0026] The first speaker 111 is installed at a first preset location in the vehicle 100, and the first piezoelectric sound-generating component 112 is installed at a second preset location in the vehicle 100.
[0027] The first loudspeaker 111 is used to output the first frequency band of the target audio signal;
[0028] The first piezoelectric sound-generating component 112 is used to output the audio signal of the second frequency band of the target audio signal, wherein the first frequency band and the second frequency band are different frequency bands.
[0029] A loudspeaker works by using an electric current to drive a voice coil to move in a magnetic field, which in turn causes the diaphragm to vibrate, producing sound. It has good response in the low and mid-frequency range, but its response to high-frequency sounds is less effective.
[0030] The working principle of piezoelectric sound-generating components is to utilize the inverse piezoelectric effect of materials (when an external voltage is applied to a piezoelectric material, compared to traditional loudspeakers, piezoelectric sound-generating components have a wider frequency response range and higher sensitivity in the high-frequency range, making them particularly suitable for scenarios that require clear high-frequency performance).
[0031] The combination of loudspeakers and piezoelectric sound-generating components outputs audio signals in different frequency bands, which can better leverage the advantages of both loudspeakers and piezoelectric sound-generating components and improve the overall sound effect.
[0032] For example, the first frequency band can be the low-to-mid frequency range (e.g., below 1kHz), and the second frequency band can be the high frequency range (e.g., above 1kHz). That is, the loudspeaker is responsible for the low-to-mid frequency part, and the piezoelectric sound-generating component is responsible for the high frequency part, thereby making up for the shortcomings of traditional loudspeakers in high frequency response and improving the high frequency sound effect of the vehicle audio system.
[0033] In some embodiments, the first speaker is installed in a first predetermined location on the vehicle, including but not limited to one or more locations such as inside the front grille, below the headlights, inside the rear grille, below the taillights, and on the chassis. Installing the speaker in a concealed location, such as at the front or bottom of the vehicle, allows for coverage of most of the vehicle, ensuring effective sound output while maintaining the consistency and aesthetics of the vehicle's exterior design.
[0034] The first piezoelectric sound-generating component includes one or more piezoelectric sound-generating components. In some embodiments, the first piezoelectric sound-generating component is installed at a second predetermined location on the vehicle. The second predetermined location includes a first body panel of the vehicle, which includes, but is not limited to, one or more body panels selected from the hood, front bumper, rear hood, rear bumper, left door, and right door. By rationally setting the distribution position of the first piezoelectric sound-generating component on the body panel, the coverage range of the external sound field can be optimized, and the sound generation effect of the external sound field can be improved. In addition, since the piezoelectric vibrator is small in size and light in weight, its installation on the body panel will not occupy too much space, nor will it affect the original structural strength and safety of the vehicle. This design also allows for flexible adjustment of the installation position and number of piezoelectric vibrators according to different vehicle models and user needs to achieve the best acoustic effect.
[0035] The system outputs different frequency bands of mono audio through a combination of a loudspeaker and a piezoelectric sound-generating component, or outputs different frequency bands of a single channel in multi-channel audio. For example, in a two-channel system, the left or right channel is output through a combination of a loudspeaker and a piezoelectric sound-generating component; in a 5.1 or 7.1 channel system, one or more channels are output through a combination of a loudspeaker and a piezoelectric sound-generating component.
[0036] In some embodiments, the target audio signal is a mono audio signal.
[0037] In other embodiments, the target audio signal is a multi-channel audio signal, a first loudspeaker is used to output an audio signal of a first frequency band of a first channel in the target audio signal; a first piezoelectric sound-generating component is used to output an audio signal of a second frequency band of the first channel; the first channel includes at least one channel in the target audio signal.
[0038] Multichannel audio signals refer to audio formats that contain multiple independent audio channels, each corresponding to a different sound direction or spatial position, providing a richer and more immersive sound experience. The first channel refers to any one or more of these independent audio channels; for example, the first channel can include any one or more of the left channel, right channel, center channel, and surround channels.
[0039] For example, in a two-channel system, the first channel can be either the left or right channel. For example, in a 5.1-channel system, the first channel can be the front main channel; for example, in a 7.1-channel system, the first channel can be the front main channel. The audio signal of the main channel is divided into a low-frequency component (output by the speaker) and a high-frequency component (output by the piezoelectric sound-generating component), enhancing the sound effect of the main channel.
[0040] In some embodiments, such as Figure 2As shown, the audio system also includes a second piezoelectric sound-generating component 113, which is installed at a third preset location in the vehicle. The second piezoelectric sound-generating component is used to output audio signals of at least a portion of the frequency bands of a second channel in the target audio signal, where the second channel includes at least one channel in the target audio signal. For multi-channel audio signals, the second piezoelectric sound-generating component outputs a portion or all of the frequency bands of another channel, further improving the overall sound effect of the audio system by utilizing the fast response and high-frequency response characteristics of the piezoelectric sound-generating component.
[0041] The second piezoelectric sound-generating component includes one or more piezoelectric sound-generating components, which are installed at a third preset location on the vehicle. This third preset location can be a second body panel, including but not limited to one or more body panels such as the hood, front bumper, rear hood, rear bumper, left door, and right door. By rationally setting the distribution position of the second piezoelectric sound-generating components on the body panels, the coverage range of the external sound field can be optimized, and the sound emission effect of the external sound field can be improved.
[0042] It should be noted that the second body panel and the first body panel can be different body panels or the same body panel.
[0043] In some embodiments, the second piezoelectric sound-generating component is used to output a full-band audio signal of the second channel in the target audio signal, wherein the full-band audio signal refers to an audio signal that covers the entire audible frequency range (e.g., 20Hz to 20kHz).
[0044] For example, the second piezoelectric sound-generating component may include a piezoelectric sound-generating component for outputting a full-frequency audio signal of the second channel.
[0045] For example, the second piezoelectric sound-generating component may also include at least two piezoelectric sound-generating components; each of the at least two piezoelectric sound-generating components is used to output a full-frequency audio signal of the second channel. By having multiple piezoelectric sound-generating components work together to output a full-frequency audio signal of the same channel, higher power audio output can be achieved, enhancing the penetration and clarity of the sound, and expanding the coverage of the sound field. At the same time, this design can avoid affecting the overall sound performance due to the failure of a single component.
[0046] In practical applications, multiple piezoelectric sound-generating components can be placed in different locations according to the vehicle's structure, such as doors, hoods, and rear hatches, to achieve a more uniform sound distribution and a better sound field effect. Through multi-point placement, the directionality and immersion of the sound can also be optimized, providing passengers with a more realistic and immersive auditory experience.
[0047] For example, the second piezoelectric sound-generating component includes at least two piezoelectric sound-generating components; different piezoelectric sound-generating components among the at least two piezoelectric sound-generating components are used to output audio signals of different frequency bands of the second channel.
[0048] Figure 3 This is an optional front view of a vehicle equipped with an audio system, as described in an embodiment of this application. Figure 3 As shown, the first speaker 111 is installed inside the front grille of the vehicle, the first piezoelectric sound-generating component 112 or a portion thereof is installed on the hood of the vehicle, and the second piezoelectric sound-generating component 113 or a portion thereof is installed on the left and right doors respectively. The first speaker 111 outputs mid-low frequency audio signals of the first channel, the first piezoelectric sound-generating component 112 outputs high frequency audio signals of the first channel, and the second piezoelectric sound-generating component 113 outputs full-frequency audio signals of the second channel.
[0049] In some embodiments, such as Figure 4 As shown, the audio system also includes a second speaker 114; the second speaker 114 is used to output the audio signal of the third frequency band of the second channel; the second piezoelectric sound-generating component 113 is used to output the audio signal of the fourth frequency band of the second channel, the third frequency band and the fourth frequency band are different frequency bands. By combining the speaker and the piezoelectric sound-generating component to output the audio signal of another channel at a different frequency band, the sound effect of that channel is improved, so that the audio signal of that channel can more accurately match its corresponding spatial position and frequency characteristics, enhancing the spatial sense and immersion of the stereo sound field.
[0050] For multi-channel audio signals, a combination of a loudspeaker and a piezoelectric sound-generating component outputs audio signals of at least two different frequency bands for each channel, improving the sound quality of at least two channels. This allows the audio signals of these channels to more accurately match their corresponding spatial positions and frequency characteristics, enhancing the spatial sense and immersiveness of the stereo sound field. For example, in a two-channel system, a combination of a first loudspeaker and a first piezoelectric sound-generating component outputs an audio signal of a different frequency band for one channel, while a combination of a second loudspeaker and a second piezoelectric sound-generating component outputs an audio signal of a different frequency band for the other channel, thus improving the two-channel sound quality.
[0051] The second speaker is installed in a fourth preset location on the vehicle, which includes at least one of the following: inside the front grille, below the headlights, inside the rear grille, below the taillights, or on the chassis. The fourth preset location and the first preset location are different vehicle locations.
[0052] Figure 5 This is an optional top view of a vehicle equipped with an audio system, as described in an embodiment of this application. Figure 5As shown, the first speaker 111 is installed inside the front grille of the vehicle, and the first piezoelectric sound-generating component 112 or a portion thereof is installed on the left and right rear doors, respectively, for outputting audio signals of different frequency bands of the first channel. The second speaker 114 is installed inside the rear grille of the vehicle, and the second piezoelectric sound-generating component 113 or a portion thereof is installed on the left and right front doors, respectively, for outputting audio signals of different frequency bands of the second channel.
[0053] In some embodiments, such as Figure 6 As shown, the audio system also includes a third speaker 115; the third speaker is used to output an audio signal of at least a portion of the frequency band of a third channel in the target audio signal, the third channel including at least one channel in the target audio signal. By introducing more speakers to cover more channels, a richer spatial sound effect is provided to the vehicle, further enhancing the spatial sense and immersiveness of the stereo sound field.
[0054] The third speaker is installed in a fifth preset location on the vehicle, which includes at least one of the following: inside the front grille, below the headlights, inside the rear grille, below the taillights, or on the chassis. The fifth preset location, the fourth preset location, and the first preset location are different vehicle locations.
[0055] In some embodiments, such as Figure 7 As shown, the audio system also includes a second speaker 114; the second speaker is used to output audio signals of at least a portion of the frequency bands of a second channel in the target audio signal, the second channel including at least one channel in the target audio signal. By introducing more speakers to cover more channels, a richer spatial sound effect is provided to the vehicle, further enhancing the spatial sense and immersiveness of the stereo sound field.
[0056] A second loudspeaker is a newly added loudspeaker in an audio system, used to expand the system's audio output capabilities. The second loudspeaker works in conjunction with other sound-producing components to output audio signals from different channels, thereby improving overall sound quality, especially in multi-channel or stereo environments.
[0057] The second speaker is installed in a fourth preset location on the vehicle, which includes at least one of the following: inside the front grille, below the headlights, inside the rear grille, below the taillights, or on the chassis. The fourth preset location and the first preset location are different vehicle locations.
[0058] In practical applications, the audio system may also include a memory and a processor. The memory stores computer programs and audio data that can run on the processor. When the processor is configured to run the computer program, it is used to distribute the target audio signal to different speakers or piezoelectric sound-generating components for output.
[0059] In practical applications, the various components of this audio system are coupled together via a bus system. This bus system is used to enable communication and connection between these components. In addition to a data bus, the bus system also includes a power bus, a control bus, and a status signal bus.
