[0003] At present, in order to avoid the resonance problem between the door bass speaker and the door sheet metal, the door is usually soundproofed with a damping plate, or the audio output gain in the range before and after the maximum resonance frequency point is reduced to reduce the output power. Filling the damping plate in the door may increase the thickness of the door, affect the overall heat dissipation of the door and the performance of related peripheral components; reducing the output frequency may cause the volume of the music around the resonance frequency point to fluctuate, affecting the intuitive impression of the sound system on the user.

[0026] Embodiment 1

[0027] Figure 1 A flow chart of a method for adjusting the door vibration frequency is provided for the first embodiment of the present invention. This embodiment is applicable to the case where a vehicle door resonates due to the vibration of a vehicle audio system. The method can be performed by a door vibration frequency adjustment device. The door vibration frequency adjustment device can be implemented in the form of hardware and / or software. The door vibration frequency adjustment device can be configured in a terminal and / or a server. Figure 1 As shown, the method includes:

[0028] S110: When it is detected that the current vibration frequency of the target door is within a preset resonance frequency range, a vibration component disposed on the target door is activated.

[0029] In this embodiment, the target door can be a door in which there is resonance between the door woofer and its fixings. In practical applications, when the woofer set in the door is working, it will not only make a sound, but also generate vibrations of different frequencies, and drive the door to vibrate together, and the vibration frequency of the door at this time can be used as the current vibration frequency. The preset resonant frequency range can be a predetermined resonant frequency band between the door and its woofer. The preset resonant frequency range can be used to determine whether the target door is in a resonant state. It should be noted that the preset resonant frequency range is related to the properties of the target door, and each door has its corresponding preset resonant frequency range, which can be determined by the frequency modulation method during the vehicle testing phase.

[0030] The vibration component may be a component with vibration capability. For example, the vibration component may be an exciter, which is a component that generates vibration according to an electrical signal after being powered on. After the cavity is sealed and securely fixed with a board of a specific material, the exciter will have the same function as a speaker. In practical applications, only the vibration capability may be retained, but the sound-generating capability is not required.

[0031] Optionally, when it is detected that the current vibration frequency of the target door is within a preset resonance frequency range, a vibration component provided on the target door is started, including: acquiring the current vibration frequency of the target door through a vibration sensor provided on the target door, and when it is detected that the current vibration frequency is within the preset resonance frequency range, generating a resonance signal and sending it to a target processor; based on the target processor and the resonance signal, generating a vibration component start instruction to start the vibration component.

[0032] The vibration sensor may be a component that determines the vibration frequency by detecting the displacement of the target door when the vibration driving force acts. The resonance signal may be a signal indicating that the target door is currently in a resonance state. The target processor may be a processor in the vehicle with a computing power processing function. Exemplarily, the target processor may be a power amplifier.

[0033] Specifically, when the audio system in the vehicle is in operation, the door bass speaker arranged in the target door plays sound in the low-frequency range and generates vibration at the same time, and drives the target door to vibrate together. The vibration sensor arranged on the target door determines the vibration frequency of the door by measuring the vibration displacement of the door when the door vibrates. When it is detected that the current vibration frequency is within the preset resonance frequency range, a resonance signal is generated and sent to the target processor, so that after receiving the resonance signal, the target processor generates a vibration component start instruction to drive the vibration component to vibrate at the corresponding vibration frequency.

[0034] S120: Determine a target vibration frequency based on the vibration frequency of the vibration component and the current vibration frequency, so that the target door vibrates based on the target vibration frequency.

[0035] In this embodiment, the target vibration frequency may be a vibration frequency generated when the target door and the vibration component vibrate together, wherein the target vibration frequency is a frequency less than or greater than a frequency within a preset resonance frequency range.

[0036] Optionally, the target vibration frequency is determined based on the vibration frequency of the vibration component and the current vibration frequency, including: based on the vibration frequency and the current vibration frequency, making the vibration component vibrate synchronously with the target door to determine the synchronous vibration function of the target door; based on the synchronous vibration function, determining the target vibration frequency.

[0037] The synchronous vibration function can be understood as a function used to represent the displacement of the target door and the vibrating component when they vibrate together. In this embodiment, the synchronous vibration function can be a function obtained by superimposing two vibration equations with the same vibration direction and different vibration angular frequencies.

[0038] Optionally, determining the synchronous vibration function of the target door includes: superimposing a first vibration function corresponding to the vibration component and a second vibration function corresponding to the target door to obtain the synchronous vibration function.

[0039] In this embodiment, the first vibration function may be a function corresponding to the vibration equation of the vibration component during the vibration process. The second vibration function may be a function corresponding to the vibration equation of the target door during the vibration process.

[0040] Exemplarily, the synchronous vibration function can be determined by the following formula, thereby determining the target vibration frequency:

[0041] After the vibration component is started, it will vibrate with a constant amplitude according to the preset frequency. Therefore, its vibration equation, that is, the first vibration function, can be made as follows:

[0042]

[0043] Among them, x1 represents the vibration displacement of the vibration component, A1 represents the amplitude of the vibration component, ω1 represents the vibration angular frequency of the vibration component, t1 represents the vibration time of the vibration component, Indicates the initial phase of vibration of the vibrating component.

[0044] Furthermore, the later stable vibration state of the target door when it is vibrated by the driving force can be studied, and its vibration equation, that is, the second vibration function, is:

[0045]

[0046] Among them, x2 represents the vibration displacement of the target door, A2 represents the amplitude of the target door, ω2 represents the vibration angular frequency of the target door, and t2 represents the vibration time of the target door. Indicates the initial vibration phase of the target door.

[0047] It should be noted that, in order to facilitate calculation, the amplitude A1=A2=A and the initial phase Therefore, the synchronous vibration equation after superposition of the two vibration equations is:

[0048]

[0049] From the above formula, we can see that the amplitude part of the synchronous vibration equation after the superposition of the two vibration equations is: Shows periodic changes, is the synchronous vibration angular frequency.

[0050] According to the relationship between frequency and angular frequency in the mechanical vibration principle: ω=2πf, the target vibration frequency can be determined as Wherein, f1 represents the vibration frequency of the vibration component, and f2 represents the current vibration frequency of the target door.

[0051] It should be noted that, through the formula of the target vibration frequency, it can be known that as long as the vibration frequency of the subsequent superimposed vibration component is reasonably controlled, the target vibration frequency of the target door can be changed to avoid the preset resonance frequency range, thereby alleviating the resonance between the door woofer and its fixings. Based on this, optionally, the vibration frequency can be less than the current vibration frequency. When controlling the vibration frequency of the vibration component, it can be considered to be less than the current vibration frequency of the target door, so that the superimposed target vibration frequency reaches below the lower limit of the preset resonance frequency range. The advantage of setting the vibration frequency of the vibration component in this way is that the vibration frequency of the vibration component is related to the transmitter power that drives its vibration. The smaller the vibration frequency, the smaller the required driving power. As a result, it can achieve the effect of both saving vehicle energy consumption and alleviating the resonance of the door.

[0052] In a specific implementation, after determining that the current vibration frequency of the target door is within a preset resonant frequency range, the vibration component on the target door is started to vibrate at a preset vibration frequency. Furthermore, based on the current vibration frequency and the vibration frequency of the vibration component, the vibration component and the target door vibrate together to determine the synchronous vibration function of the target door. By analyzing the synchronous vibration function, the target vibration frequency of the target door after the vibration component is started is determined, so that the target door continues to vibrate according to the target vibration frequency.

[0053] The technical solution of the embodiment of the present invention is to start the vibration component arranged on the target door when it is detected that the current vibration frequency of the target door is within the preset resonance frequency range. Further, based on the vibration frequency of the vibration component and the current vibration frequency, the target vibration frequency is determined so that the target door vibrates based on the target vibration frequency. This solves the problem in the prior art that filling a damping plate in the door may increase the thickness of the door, affect the overall heat dissipation of the door and the performance of related peripheral components; reducing the output frequency may cause the volume of the music to fluctuate when the user listens to music around the resonance frequency point, affecting the intuitive impression brought by the audio system to the user. This realizes that the vibration frequency of the door is changed by superimposing new vibrations to avoid the resonance frequency band between the target door and the door bass speaker, thereby achieving the effect of alleviating the resonance of the door. In addition, the vibration frequency of the subsequently superimposed vibration component is controlled as much as possible within a lower frequency range, which can further achieve the effect of saving vehicle energy consumption on the basis of alleviating the resonance.

[0054] Embodiment 2

[0055] Figure 2 This is a flow chart of a door vibration frequency adjustment method provided in the second embodiment of the present invention. Based on the above embodiment, this embodiment adds a process for determining a preset resonance frequency range. Figure 2 As shown, the method includes:

[0056] S210: Play a sound within a target low-frequency range through an audio system disposed on the target vehicle door to determine a vibration displacement curve of the target vehicle door.

[0057] The sound system may include a door bass speaker installed on the target vehicle door. The target low frequency range may be understood as a bass frequency band that is usually played in the sound system. For example, the target low frequency range may be 20 Hz-80 Hz, etc. The vibration displacement curve may be a curve for representing the corresponding relationship between the vibration displacement and time generated by the target vehicle door under the forced vibration of the bass vibration of the sound system.

[0058] In practical applications, in order to determine the resonant frequency band of the target door and the door bass speaker in the audio system, sounds of different frequencies within the target low-frequency range can be played, and the vibration displacement of the target door at different frequencies can be detected by a vibration sensor and sent to the processor to determine the vibration displacement curve of the target door.

[0059] Exemplarily, the vibration displacement curve can be determined by the following formula:

[0060] The process of the door bass speaker driving the target door to vibrate together can be regarded as applying a periodic external force to the target door, and the target door is forced to vibrate under the action of the periodic driving force. Therefore, the formula of the driving force can be set as:

[0061] F=F0cosω d t

[0062] Where F0 represents the magnitude of the driving force, ω d represents the angular frequency of the driving force, and t represents the action time of the driving force.

[0063] It should be noted that when the target door is forced to vibrate under the action of the driving force, since the target door will produce elastic deformation during the vibration process, a corresponding elastic force will be generated to restore the elastic deformation. Since the target door is forced to vibrate, there will be a corresponding resistance to prevent the vibration of the target door. Therefore, when the target door vibrates together with the door bass speaker, not only the driving force acts on the target door, but also the elastic force and resistance. The direction of the elastic force and resistance is opposite to that of the driving force. Therefore, according to Newton's second law of motion, that is, the acceleration of an object is proportional to the resultant external force, the motion equation of the target door can be:

[0064]

[0065] Wherein, m represents the mass of the target door, x represents the displacement of the target door, k represents the elastic coefficient of the target door, and γ represents the damping coefficient.

[0066] In order to facilitate calculation, we can Then the above formula can be transformed into:

[0067]

[0068] When solving the above linear homogeneous differential equation, the damping can be ignored, that is, the solution when the damping is small (γ = 0) is:

[0069]

[0070] From the above formula, we can know that: at the stage when the driving force begins to act, the vibration of the target door is relatively complex and can be regarded as the synthesis of two vibration processes. After a period of time, the first vibration will weaken to negligible, and the second is the constant amplitude vibration when the forced vibration of the target door reaches a stable state, that is, the harmonic vibration. Figure 3 As shown, the target door reaches a stable state after being forced to vibrate for a period of time.

[0071] S220: Determine a preset resonance frequency range of the target door based on the vibration displacement curve.

[0072] Generally, the vibration frequency corresponding to the highest point of the vibration displacement is determined by analyzing the vibration displacement curve of the target door, and the preset resonance frequency range of the target door is determined according to the vibration frequencies corresponding to the adjacent peaks on the left and right sides of the highest point of the vibration displacement.

[0073] Optionally, based on the vibration displacement curve, a preset resonant frequency range of the target door is determined, including: based on the vibration displacement curve, determining a target displacement peak value, and determining a first displacement peak value and a second displacement peak value adjacent to the left and right sides of the target displacement peak value; and taking a frequency range between a first frequency corresponding to the first displacement peak value and a second frequency corresponding to the second displacement peak value as a preset resonant frequency range.

[0074] In this embodiment, the target displacement peak value can be understood as the displacement corresponding to the highest point of the vibration displacement in the vibration displacement curve. The first displacement peak value can be the displacement corresponding to the relatively higher point of the vibration displacement on the left adjacent to the target displacement peak value. The second displacement peak value can be the displacement corresponding to the relatively higher point of the vibration displacement on the right adjacent to the target vibration displacement peak value.

[0075] In a specific implementation, after obtaining the vibration displacement curve of the target door, the target displacement peak value of the target door during the vibration process is determined by analyzing the curve. Furthermore, the first displacement peak value and the second displacement peak value adjacent to the left and right sides of the target displacement peak value are determined, and the frequency range between the first frequency corresponding to the first displacement peak value and the second frequency corresponding to the second displacement peak value is used as the preset resonance frequency range.

[0076] S230: When it is detected that the current vibration frequency of the target door is within a preset resonance frequency range, a vibration component disposed on the target door is activated.

[0077] S240: Determine a target vibration frequency based on the vibration frequency of the vibration component and the current vibration frequency, so that the target door vibrates based on the target vibration frequency.

[0078] The technical solution of the embodiment of the present invention is as follows: first, a sound within a target low-frequency range is played by an audio system arranged on a target door to determine a vibration displacement curve of the target door; then, based on the vibration displacement curve, a preset resonance frequency range of the target door is determined; further, when it is detected that the current vibration frequency of the target door is within the preset resonance frequency range, a vibration component arranged on the target door is started; finally, based on the vibration frequency of the vibration component and the current vibration frequency, a target vibration frequency is determined so that the target door vibrates based on the target vibration frequency, thereby solving the problem that filling a damping plate in a door in the prior art may increase the thickness of the door, affect the heat dissipation of the door as a whole, and the performance of related peripheral components; reducing the output frequency may cause the volume of the music before and after the resonance frequency point to fluctuate, thereby affecting the intuitive impression of the audio system on the user; and realizing that the vibration frequency of the door is changed by superimposing a new vibration to avoid the resonance frequency band between the target door and the door bass speaker, thereby achieving the effect of alleviating the resonance of the door; and the vibration frequency of the subsequent superimposed vibration component is controlled as much as possible within a lower frequency range, thereby further achieving the effect of saving vehicle energy consumption on the basis of alleviating the resonance.

[0083] The technical solution of the embodiment of the present invention is to start the vibration component arranged on the target door when it is detected that the current vibration frequency of the target door is within the preset resonance frequency range. Further, based on the vibration frequency of the vibration component and the current vibration frequency, the target vibration frequency is determined so that the target door vibrates based on the target vibration frequency. This solves the problem in the prior art that filling a damping plate in the door may increase the thickness of the door, affect the overall heat dissipation of the door and the performance of related peripheral components; reducing the output frequency may cause the volume of the music to fluctuate when the user listens to music around the resonance frequency point, affecting the intuitive impression brought by the audio system to the user. This realizes that the vibration frequency of the door is changed by superimposing new vibrations to avoid the resonance frequency band between the target door and the door bass speaker, thereby achieving the effect of alleviating the resonance of the door.
