Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a sound-generating component and an electronic device. Background Technology

[0002] In related technologies, loudspeakers typically include dynamic loudspeakers and ceramic loudspeakers.

[0003] like Figure 1 As shown, the ceramic loudspeaker includes a diaphragm 102', a ceramic disc 104', and a circuit board 106'. Compared to a moving-coil loudspeaker, the ceramic loudspeaker does not require a coil or magnetic circuit assembly. However, due to the high rigidity of the ceramic material, the ceramic disc 104' lacks sufficient vibration flexibility when emitting mid-to-low frequency sounds, thus affecting the sound quality. Utility Model Content

[0004] This application aims to provide a sound-generating component and electronic device that can solve the technical problem of unsatisfactory sound generation effect of ceramic loudspeakers when emitting mid-to-low frequency sounds in the related art.

[0005] In a first aspect, embodiments of this application provide a sound-generating component, comprising:

[0006] Diaphragm;

[0007] The first vibration component includes a plurality of first piezoelectric diaphragms, which are arranged at intervals on the diaphragm.

[0008] The second vibration component includes a plurality of second piezoelectric diaphragms, which are spaced apart on the diaphragm and the extension direction of the second piezoelectric diaphragms is not parallel to the extension direction of the first piezoelectric diaphragm.

[0009] A control component is electrically connected to a first piezoelectric diaphragm and a second piezoelectric diaphragm. The control component is used to receive an audio signal and drive the first target diaphragm and the second target diaphragm to vibrate at their natural frequencies according to a first frequency of the audio signal.

[0010] The first target diaphragm is one of a plurality of first piezoelectric diaphragms, and the second target diaphragm is one of a plurality of second piezoelectric diaphragms. The natural frequency of the first target diaphragm is the same as that of the second target diaphragm, and the natural frequencies of the first and second target diaphragms are matched with the first frequency.

[0011] Secondly, embodiments of this application provide an electronic device including a sound-generating component as described in the first aspect.

[0012] This embodiment of the application, by setting multiple first and second piezoelectric diaphragms with different inherent frequencies on the diaphragm, allows the sound-generating component to transmit audio signals to corresponding first and second target diaphragms according to a first frequency of the audio signal when sound generation is required. The first and second target diaphragms have the same inherent frequency and match the first frequency, enabling them to have high amplitude vibrations during operation. This ensures the loudness of the sound emitted by the sound-generating component, guaranteeing high loudness across all frequency bands, thus widening the frequency response bandwidth of the sound-generating component. This ensures effective sound generation regardless of whether the sound is high-frequency or mid-to-low-frequency. Furthermore, by cross-arranging the first and second piezoelectric diaphragms, the diaphragm can be connected as a whole, allowing the entire diaphragm to vibrate, avoiding sound distortion and further ensuring the sound generation effect of the component.

[0030] The following is combined Figures 3 to 9 This application describes a sound-generating component and an electronic device according to embodiments thereof.

[0031] In some embodiments of this application, a sound-generating component is provided. Figure 3One of the structural schematic diagrams of the sound-generating component according to an embodiment of this application is shown; Figure 4 A second schematic diagram of the structure of the sound-generating component according to an embodiment of this application is shown; Figure 5 The third schematic diagram of the structure of the sound-generating component according to an embodiment of this application is shown; Figure 8 The fourth schematic diagram of the structure of the sound-generating component according to an embodiment of this application is shown; as follows: Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the sound-generating assembly 100 includes: a diaphragm 102; a first vibration assembly 104 including a plurality of first piezoelectric diaphragms 1042, the plurality of first piezoelectric diaphragms 1042 being spaced apart from the diaphragm 102; a second vibration assembly 106 including a plurality of second piezoelectric diaphragms 1062, the plurality of second piezoelectric diaphragms 1062 being spaced apart from the diaphragm 102, the extending direction of the second piezoelectric diaphragms 1062 being non-parallel to the extending direction of the first piezoelectric diaphragms 1042; and a control assembly 108 electrically connected to the first piezoelectric diaphragms 1042 and the second piezoelectric diaphragms 1062, the control assembly 108 using... The device receives an audio signal and drives a first target diaphragm 10422 and a second target diaphragm 10622 to vibrate at their natural frequencies according to a first frequency of the audio signal. The first target diaphragm 10422 is one of a plurality of first piezoelectric diaphragms 1042, and the second target diaphragm 10622 is one of a plurality of second piezoelectric diaphragms 1062. The natural frequencies of the first target diaphragm 10422 and the second target diaphragm 10622 are the same, and the natural frequencies of the first target diaphragm 10422 and the second target diaphragm 10622 are matched with the first frequency.

[0032] In this embodiment, the sound-generating component 100 may include a diaphragm 102. It is understood that the main principle by which the sound-generating component 100 generates sound is through the mechanical vibration of the diaphragm 102. During the vibration of the diaphragm 102, friction occurs between the diaphragm 102 and the surrounding air, thereby generating sound. Simultaneously, the pitch of the emitted sound can be adjusted by regulating the vibration frequency of the diaphragm 102, and the loudness of the emitted sound can be adjusted by regulating the amplitude of the diaphragm 102.

[0033] Furthermore, the sound-generating component 100 also includes a first vibration component 104, a second vibration component 106, and a control component 108. The first vibration component 104 may include a plurality of first piezoelectric diaphragms 1042, and the second vibration component 106 includes a plurality of second piezoelectric diaphragms 1062. Both the first and second piezoelectric diaphragms 1042 and 1062 are electrically connected to the control component 108. Specifically, the control component 108 can receive and transmit audio signals to drive the first and second piezoelectric diaphragms 1042 and 1062 to vibrate according to a first frequency of the audio signal. Specifically, when the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062 receive an audio signal, that is, when they receive a voltage signal, based on the piezoelectric effect of the piezoelectric diaphragms, the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062 generate mechanical vibration. At the same time, the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062 drive the diaphragm 102 to vibrate, thereby causing the diaphragm 102 to generate mechanical vibration, and then emitting sound during the vibration of the diaphragm 102.

[0034] It should be noted that the natural frequencies of the multiple first piezoelectric diaphragms 1042 are not the same. Specifically, the natural frequencies of the multiple first piezoelectric diaphragms 1042 can be X, 1X, 2X, 3X...NX, where X is a frequency value, which can be set according to the actual sound generation requirements of the sound-generating component 100. For example, X can be 300Hz, and N is the number of first piezoelectric diaphragms 1042. Correspondingly, the natural frequencies of the multiple second piezoelectric diaphragms 1062 can also be X, 1X, 2X, 3X...NX.

[0035] It is understandable that the natural frequency of the piezoelectric diaphragm can be calculated using formula (1):

[0036]

[0037] Where F0 is the natural frequency, K is the elastic modulus of the piezoelectric diaphragm (in N / m), and m is the mass of the diaphragm 102 (in kg). It is evident that the natural frequency of the piezoelectric diaphragm is related to its elastic modulus and mass. Since the multiple first piezoelectric diaphragms 1042 are made of the same material, their elastic modulus is identical. Therefore, different natural frequencies can be achieved by setting different masses for the multiple first piezoelectric diaphragms 1042. Simultaneously, the mass of the first piezoelectric diaphragm 1042 is related to its length, width, and thickness. Thus, different natural frequencies can be achieved by setting different lengths, widths, and thicknesses for the multiple first piezoelectric diaphragms 1042. Correspondingly, different natural frequencies can be achieved by setting different lengths, widths, and thicknesses for the multiple second piezoelectric diaphragms 1062.

[0038] Furthermore, the control component 108 can specifically drive the first target diaphragm 10422 and the second target diaphragm 10622 to vibrate at their natural frequencies according to the first frequency of the audio signal. It should be noted that the first target diaphragm 10422 is one of a plurality of first piezoelectric diaphragms 1042, and the second target diaphragm 10622 can be one of a plurality of second piezoelectric diaphragms 1062. At the same time, the natural frequencies of the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062 are the same, and the natural frequencies of the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062 are both matched with the first frequency of the audio signal.

[0039] For example, when it is necessary to control the sound-emitting component 100 to emit an audio signal of 300Hz, that is, when the first frequency of the audio signal is 300Hz, the control component 108 can drive the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062 with a natural frequency of 300Hz to vibrate, that is, the first target diaphragm 10422 and the second target diaphragm 10622. At this time, among the multiple first piezoelectric diaphragms 1042 and the multiple second piezoelectric diaphragms 1062, only the first target diaphragm 10422 and the second target diaphragm 10622 with a natural frequency that matches the first frequency of the audio signal will vibrate.

[0040] Understandably, when the sound-generating component 100 needs to emit an audio signal at the first frequency, the first target diaphragm 10422 and the second target diaphragm 10622 vibrate. At this time, since the natural frequencies of the first target diaphragm 10422 and the second target diaphragm 10622 match the first frequency of the audio signal, the amplitudes of the first target diaphragm 10422 and the second target diaphragm 10622 are relatively high, thereby ensuring the loudness of the audio signal at the first frequency emitted by the sound-generating component 100.

[0041] Furthermore, since the multiple first piezoelectric diaphragms 1042 and the multiple second piezoelectric diaphragms 1062 have different inherent frequencies, the corresponding first target diaphragm 10422 and second target diaphragm 10622 can be matched according to the first frequency of the audio to be emitted by the sound-emitting component 100. This ensures that the sound-emitting component 100 can match the vibration of the first target diaphragm 10422 and second target diaphragm 10622 corresponding to the audio signal, regardless of the frequency of sound to be emitted. In other words, it ensures that the first target diaphragm 10422 and second target diaphragm 10622 will generate a high amplitude regardless of the frequency of sound to be emitted, thereby ensuring that the audio in all frequency bands can have a high loudness.

[0042] Compared to sound-generating components in related technologies that use only a single piezoelectric diaphragm, the sound-generating component 100 of this application embodiment can achieve high loudness across all frequency bands, thus broadening the frequency response bandwidth of the sound-generating component 100. Therefore, regardless of whether the sound is high-frequency or mid-to-low-frequency, the sound-generating effect of the sound-generating component 100 can be guaranteed. Specifically, Figure 6 The frequency response curve of the sound-generating component according to an embodiment of this application is shown; as follows: Figure 6 As shown, the frequency response curve of the sound-generating component 100 of this application is obtained by fitting the frequency response curves of a plurality of first piezoelectric diaphragms 1042 or a plurality of second piezoelectric diaphragms 1062. Figure 6 and Figure 2 The comparison shows that, compared with the sound-generating components in related technologies that only use a piezoelectric diaphragm, the sound-generating component 100 of this application has a significantly larger frequency range with higher loudness, that is, it broadens the frequency response bandwidth of the sound-generating component 100 and improves the sound-generating effect of the sound-generating component 100.

[0043] Furthermore, such as Figure 5 As shown, the extension direction A of the first piezoelectric diaphragm 1042 and the extension direction B of the second piezoelectric diaphragm 1062 are not parallel, that is, the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062 are intersected. In this way, when the first target diaphragm 10422 and the second target diaphragm 10622 vibrate, the overall stiffness of the diaphragm 102 can be improved by the differentially arranged first target diaphragm 10422 and second target diaphragm 10622, that is, the diaphragm 102 is connected as a whole, thereby driving the diaphragm 102 to vibrate as a whole, ensuring that the diaphragm 102 can vibrate at the required frequency, that is, ensuring the sound production effect of the sound-generating component 100. This avoids only controlling the vibration of the first target diaphragm 10422, which would affect the first piezoelectric diaphragms 1042 on both sides of the first target diaphragm 10422, causing the first piezoelectric diaphragms 1042 on both sides of the first target diaphragm 10422 to vibrate at different frequencies, thereby causing the sound emitted by the sound-generating component 100 to be distorted.

[0044] This embodiment of the application provides multiple first piezoelectric diaphragms 1042 and second piezoelectric diaphragms 1062 with different inherent frequencies on the diaphragm 102. When the sound-generating component 100 needs to generate sound, the control component 108 can transmit the audio signal to the corresponding first target diaphragm 10422 and second target diaphragm 10622 according to the first frequency of the audio signal. The inherent frequencies of the first target diaphragm 10422 and the second target diaphragm 10622 are the same and matched with the first frequency, so that the first target diaphragm 10422 and the second target diaphragm 10622 can have a high amplitude during vibration, thereby ensuring the loudness of the sound emitted by the sound-generating component 100. This ensures that the audio in all frequency bands can have a high loudness, that is, it broadens the frequency response bandwidth of the sound-generating component 100, so that the sound-generating effect of the sound-generating component 100 can be guaranteed regardless of whether it is a high-frequency sound or a mid-low frequency sound. Meanwhile, by cross-arranging the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062, the diaphragm 102 can be connected into a whole, thereby driving the diaphragm 102 to vibrate as a whole, avoiding sound distortion, and further ensuring the sound production effect of the sound-generating component 100.

[0045] In some embodiments of this application, the control component 108 includes: a power amplifier 1082 for receiving and amplifying an audio signal; and a controller 1084 electrically connected to the power amplifier 1082. The controller 1084 receives the amplified audio signal and drives a first target diaphragm 10422 and a second target diaphragm 10622 to vibrate at their natural frequencies according to a first frequency of the audio signal. The controller 1084 is also used to drive at least one third target diaphragm 10424 and at least one fourth target diaphragm 10624 to vibrate at their natural frequencies according to the first frequency of the audio signal. The third target diaphragm 10424 belongs to the first piezoelectric diaphragm 1042, and the natural frequency of the third target diaphragm 10424 is an even multiple of the natural frequency of the first target diaphragm 10422. The fourth target diaphragm 10624 belongs to the second piezoelectric diaphragm 1062, and the natural frequency of the fourth target diaphragm 10624 is an even multiple of the natural frequency of the second target diaphragm 10622.

[0046] In the embodiments of this application, Figure 7 A schematic diagram of the control component in the sound-generating component of this application embodiment is shown; as follows: Figure 7 As shown, the control component 108 may include a power amplifier 1082 and a controller 1084. The power amplifier 1082 is used to receive audio signals and amplify the power of the audio signals to ensure that the audio signals can be effectively received and to avoid the audio signals being too weak to be effectively transmitted to the first target diaphragm 10422 and the second target diaphragm 10622.

[0047] Furthermore, the controller 1084 is electrically connected to the power amplifier 1082, enabling the controller 1084 to receive the amplified audio signal. Simultaneously, the controller 1084 is also electrically connected to multiple first piezoelectric diaphragms 1042 and multiple second piezoelectric diaphragms 1062, allowing the controller 1084 to drive the first target diaphragm 10422 and the second target diaphragm 10622 to vibrate at their natural frequencies according to the first frequency of the audio signal, thereby achieving the vibration of the first target diaphragm 10422 and the second target diaphragm 10622 to realize the sound-generating function of the sound-generating component 100.

[0048] For example, the control component 108 may also include a flexible connection port 1086, through which the controller 1084 and the power amplifier 1082 can be connected. Based on the flexibility of the flexible connection port 1086, the connection between the controller 1084 and the power amplifier 1082 is realized, making the setting positions of the controller 1084 and the power amplifier 1082 more flexible.

[0049] Furthermore, the controller 1084 can also be used to drive at least one third target diaphragm 10424 and at least one fourth target diaphragm 10624 to vibrate according to a first frequency of the audio signal, thereby causing the third target diaphragm 10424 and the fourth target diaphragm 10624 to vibrate. It should be noted that the third target diaphragm 10424 belongs to the first piezoelectric diaphragm 1042, and the natural frequency of the third target diaphragm 10424 is an even multiple of the natural frequency of the first target diaphragm 10422. For example, if the natural frequency of the first target diaphragm 10422 is Y, then the natural frequencies of the plurality of third target diaphragms 10424 can be 2Y, 4Y, 6Y, etc. Correspondingly, the fourth target diaphragm 10624 belongs to the second piezoelectric diaphragm 1062, and the natural frequency of the fourth target diaphragm 10624 is an even multiple of the natural frequency of the second target diaphragm 10622. For example, if the natural frequency of the second target membrane 10622 is Y, then the natural frequencies of the plurality of fourth target membranes 10624 can be 2Y, 4Y, 6Y, etc.

[0050] Furthermore, while the control component 108 drives the third target diaphragm 10424 and the fourth target diaphragm 10624 to vibrate at their inherent frequencies, it can also adjust the voltage values ​​of the audio signals transmitted to the third target diaphragm 10424 and the fourth target diaphragm 10624. The voltage values ​​of the audio signals transmitted to the third target diaphragm 10424 and the fourth target diaphragm 10624 can be adjusted according to the actual sound production effect. Typically, the peak value of the voltage values ​​of the audio signals transmitted to the third target diaphragm 10424 and the fourth target diaphragm 10624 can be adjusted to be lower than the peak value of the voltage values ​​transmitted to the first target diaphragm 10422 and the second target diaphragm 10622, thereby further improving the sound production effect of the sound production component 100.

[0051] This embodiment of the application, by setting a power amplifier 1082, can amplify the audio signal, ensuring that the audio signal can be effectively received. The controller 1084 can distribute the audio signal, driving the first target diaphragm 10422 and the second target diaphragm 10622 to vibrate according to the first frequency of the audio signal, ensuring that the sound-generating component 100 can achieve high loudness across all frequency bands. Simultaneously, while the first target diaphragm 10422 and the second target diaphragm 10622 vibrate, the controller 1084 can also drive the third target diaphragm 10424 and the fourth target diaphragm 10624 to vibrate according to the first frequency of the audio signal. This causes the third target diaphragm 10424 and the fourth target diaphragm 10624 to vibrate simultaneously, thereby achieving simultaneous vibration of the piezoelectric diaphragm whose natural frequency is an even multiple of the natural frequency of the first target diaphragm 10422 and the piezoelectric diaphragm whose natural frequency is an even multiple of the natural frequency of the second target diaphragm 10622. This further enhances the sound-generating effect of the sound-generating component 100 and improves the user experience.

[0052] In some embodiments of this application, the sound-generating component 100 further includes: a plurality of connecting contacts 110 connected to a controller 1084, wherein the plurality of connecting contacts 110 are connected one-to-one with a plurality of first piezoelectric diaphragms 1042 and a plurality of second piezoelectric diaphragms 1062; wherein the controller 1084 is used to drive the first target diaphragm 10422 and the second target diaphragm 10622 to vibrate according to a first frequency of an audio signal through the connecting contacts 110.

[0053] In the embodiments of this application, such as Figure 3 and Figure 4As shown, the sound-generating component 100 may further include multiple connecting contact points 110, all of which are connected to the controller 1084. Each connecting contact point 110 is connected to a corresponding first piezoelectric diaphragm 1042 and a corresponding second piezoelectric diaphragm 1062. That is, the controller 1084 can use the multiple connecting contact points 110 to drive the corresponding first piezoelectric diaphragm 1042 and second piezoelectric diaphragm 1062 according to a first frequency of the audio signal, i.e., drive the first target diaphragm 10422 and the second target diaphragm 10622 to vibrate. This allows the first target diaphragm 10422 and the second target diaphragm 10622 to vibrate at their natural frequencies based on the piezoelectric effect of the piezoelectric diaphragms, thereby causing the diaphragm 102 to vibrate and realizing the sound-generating function of the sound-generating component 100.

[0054] In some embodiments of this application, the sound-generating component 100 further includes: a support portion 112 for supporting the diaphragm 102; wherein the edge of the diaphragm 102 is connected to the support portion 112, a plurality of contact points 110 are disposed on the support portion 112, and a controller 1084 is disposed on the support portion 112.

[0055] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, the sound-generating component 100 may also include a support portion 112. By providing the support portion 112, the diaphragm 102 can be supported, thereby ensuring that when the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062 vibrate, the diaphragm 102 can vibrate along with the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062, thereby realizing the sound-generating function of the sound-generating component 100.

[0056] Specifically, the edge of the diaphragm 102 is connected to the support portion 112, thereby enabling the diaphragm 102 as a whole to vibrate. Correspondingly, a plurality of connecting contact points 110 are provided on the support portion 112, so that the plurality of connecting contact points 110 can be connected to a plurality of first piezoelectric diaphragms 1042 and a plurality of second piezoelectric diaphragms 1062 located on the diaphragm 102.

[0057] In some embodiments of this application, the support 112 includes: a basin frame 1122, the edge of the diaphragm 102 is connected to one side of the edge of the basin frame 1122, and a plurality of contact points 110 are spaced apart on the basin frame 1122; a rear cover 1124 is connected to the other side of the edge of the basin frame 1122, and a controller 1084 is disposed on the rear cover 1124.

[0058] In the embodiments of this application, such as Figure 4As shown, the support portion 112 may include a frame 1122 and a rear cover 1124. The frame 1122 is used to support the diaphragm 102, that is, the edge of the diaphragm 102 can be connected to one side of the edge of the frame 1122. Specifically, the frame 1122 can be configured as an annular shape, which, while connecting to the edge of the diaphragm 102, also provides vibration space for the diaphragm 102, ensuring that the diaphragm 102 can vibrate effectively, thereby ensuring that the sound-generating assembly 100 can emit sound normally.

[0059] Meanwhile, multiple connecting contact points 110 can be disposed on the frame 1122. While the frame 1122 is connected to the edge of the diaphragm 102, the multiple connecting contact points 110 disposed on the frame 1122 can be electrically connected to the multiple first piezoelectric diaphragms 1042 and multiple second piezoelectric diaphragms 1062 disposed on the diaphragm 102, so as to realize the transmission of audio signals to the multiple first piezoelectric diaphragms 1042 and multiple second piezoelectric diaphragms 1062. Specifically, the multiple connecting contact points 110 can be distributed at intervals on the frame according to the specific placement positions of the multiple first piezoelectric diaphragms 1042 and multiple second piezoelectric diaphragms 1062 on the diaphragm 102, so as to ensure that each connecting contact point 110 can be electrically connected to the corresponding first piezoelectric diaphragm 1042 or second piezoelectric diaphragm 1062. Specifically, the contact point 110 can be electrically connected to the first piezoelectric diaphragm 1042 or the second piezoelectric diaphragm 1062 via a flexible circuit board, an ITO conductive film, or a copper wire lamp electrical connector. The electrical connector can be integrally set on the diaphragm surface or set independently of the diaphragm.

[0060] Furthermore, the other edge of the basin frame 1122 can be connected to the back cover 1124, thereby supporting the basin frame 1122 through the back cover 1124, preventing the basin frame 1122 from being deformed by impacts from external objects, thus ensuring that the shape of the diaphragm 102 does not change, thereby ensuring the sound effect emitted by the vibration of the diaphragm 102 and preventing sound distortion in the sound-generating component 100.

[0061] Meanwhile, the controller 1084 can be mounted on the rear cover 1124, thereby supporting the controller 1084 and ensuring the stability of its mounting position. Furthermore, the rear cover 1124 is connected to the edge of the basin stand 1122, allowing the controller 1084 to achieve electrical connection with multiple contact points 110 on the basin stand 1122 via wiring provided on the rear cover 1124.

[0062] In some embodiments of this application, the support portion 112 further includes a washer 1126 disposed between the basin frame 1122 and the rear cover 1124.

[0063] In the embodiments of this application, such as Figure 4As shown, the support portion 112 may further include a washer 1126, and the washer 1126 is disposed between the frame 1122 and the rear cover 1124. By providing the washer 1126, on the one hand, the rear cover 1124 can isolate vibration when the diaphragm 102 vibrates, preventing vibration from being transmitted to the rear cover 1124 and generating unnecessary vibration noise. On the other hand, it can also achieve insulation between the rear cover 1124 and the multiple contact points 110 on the frame 1122, preventing the contact points 110 from receiving unnecessary electrical signals that would affect the vibration frequency of the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062, thereby ensuring the sound-generating effect of the sound-generating assembly 100.

[0064] For example, the washer 1126 may be made of a material that is elastic and has insulating properties, such as silicone.

[0065] In some embodiments of this application, a plurality of first piezoelectric diaphragms 1042 are arranged in parallel to each other, and a plurality of second piezoelectric diaphragms 1062 are arranged in parallel to each other. The angle between the extension direction of the second piezoelectric diaphragm 1062 and the extension direction of the first piezoelectric diaphragm 1042 is greater than or equal to 60 degrees and less than or equal to 90 degrees.

[0066] In the embodiments of this application, such as Figure 5 As shown, multiple first piezoelectric diaphragms 1042 can be arranged in parallel with each other. In this way, when the first target diaphragm 10422 among the multiple first piezoelectric diaphragms 1042 vibrates, it can effectively reduce the impact on other first piezoelectric diaphragms 1042, that is, avoid the first target diaphragm 10422 from driving other first piezoelectric diaphragms 1042 to vibrate, thereby avoiding the impact on the sound generation effect of the sound generation component 100.

[0067] Similarly, multiple second piezoelectric diaphragms 1062 can be arranged in parallel to each other. In this way, when the second target diaphragm 10622 among the multiple second piezoelectric diaphragms 1062 vibrates, the impact on other second piezoelectric diaphragms 1062 can be effectively reduced. That is, the second target diaphragm 10622 is prevented from driving other second piezoelectric diaphragms 1062 to vibrate, thereby avoiding the impact on the sound generation effect of the sound generating component 100.

[0068] Furthermore, the angle between the extension direction of the first piezoelectric diaphragm 1042 and the extension direction of the second piezoelectric diaphragm 1062 can be set to be greater than or equal to 60 degrees and less than or equal to 90 degrees. That is, the angle between the extension directions of the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062 is between 60 degrees and 90 degrees. In this way, during the sound generation process of the sound generation component 100, the diaphragm 102 can be connected into a whole by the first target diaphragm 10422 and the second target diaphragm 10622, which improves the overall stiffness of the diaphragm 102 and ensures that the diaphragm 102 can vibrate as a whole. At the same time, it can also avoid the impact of the vibration frequency of the diaphragm 102 when the first target diaphragm 10422 and the second target diaphragm 10622 vibrate simultaneously, thus ensuring the vibration frequency of the diaphragm 102 and the sound generation effect of the sound generation component 100.

[0069] In some embodiments of this application, the first vibration component 104 and the second vibration component 106 are respectively disposed on both sides of the diaphragm 102.

[0070] In the embodiments of this application, such as Figure 4 and Figure 8 As shown, the first vibration component 104 and the second vibration component 106 can be respectively disposed on both sides of the diaphragm 102. In this way, the first piezoelectric diaphragm 1042 of the first vibration component 104 and the second piezoelectric diaphragm 1062 of the second vibration component 106 can be avoided from direct contact, thereby avoiding mutual influence between the first piezoelectric diaphragm 1042 and the second piezoelectric diaphragm 1062 during vibration, that is, avoiding the impact on the sound generation effect of the sound generation component 100.

[0071] In some embodiments of this application, the sound-generating component 100 further includes: a buffer layer 114 disposed between the first vibration component 104 and the diaphragm 102, and / or disposed between the second vibration component 106 and the diaphragm 102.

[0072] In the embodiments of this application, such as Figure 4 As shown, the sound-generating component 100 may further include a buffer layer 114. The buffer layer 114 may be disposed between the first vibrating component 104 and the diaphragm 102, or between the second vibrating component 106 and the diaphragm 102. Alternatively, the buffer layer 114 may be disposed simultaneously between the first vibrating component 104 and the diaphragm 102, and between the second vibrating component 106 and the diaphragm 102. Thus, the buffer layer 114 isolates and buffers the first vibrating component 104 and the second vibrating component 106, preventing them from interfering with each other during vibration, thereby avoiding any impact on the sound-generating effect of the sound-generating component 100.
