在耗散系统中,摩擦功率和弹性形变能量是线性相关,为了增大耗散,通常方法是增大能量密度,而利用共振结构130中的导音通道134可以达到这一目的。In a dissipative system, frictional power and elastic deformation energy are linearly related. In order to increase dissipation, the usual method is to increase energy density, which can be achieved by using the sound guiding channel 134 in the resonant structure 130 .

共振结构130包括导音口132和多个导音通道134,导音口132与导音通道134均相连通,其可以是直接连通或间接连通,并且,导音口132还与前腔112相连通,进而前腔112中的声波可以通过导音口132进入到多个导音通道134中,从而利用声波在多个导音通道134内的反射,吸收目标频率的声波,降低频响曲线中的高频峰,提升扬声器音频播放的效果。The resonance structure 130 includes a sound guide port 132 and a plurality of sound guide channels 134. The sound guide port 132 is connected to the sound guide channels 134, which can be directly connected or indirectly connected, and the sound guide port 132 is also connected to the front chamber 112. The sound wave in the front cavity 112 can then enter the multiple sound guide channels 134 through the sound guide port 132, so that the sound wave of the target frequency can be absorbed by the reflection of the sound wave in the multiple sound guide channels 134, and the frequency response curve can be reduced. High-frequency peaks to enhance the effect of speaker audio playback.

其中,发声单元120包括振膜,振膜振动使得前腔112内的空气振动,形成声波,再有出声口116传播到扬声器100的外部。Wherein, the sound generating unit 120 includes a diaphragm, and the vibration of the diaphragm makes the air in the front cavity 112 vibrate to form sound waves, which are transmitted to the outside of the speaker 100 through the sound outlet 116 .

以及,目标频段可以是4kHz到6kHz的频段,本申请中采用的共振结构130能够实现在较小空间占用下,吸收4kHz到6kHz频段共振峰的声波能量,降低重放音频中齿音部分能量,提升音频播放效果,提升用户的听感。And, the target frequency band can be the frequency band from 4kHz to 6kHz. The resonant structure 130 used in this application can absorb the sound wave energy of the formant in the frequency band from 4kHz to 6kHz in a small space occupation, and reduce the energy of the tooth sound in the playback audio. Improve the audio playback effect and enhance the user's sense of hearing.

如图4和图5所示,作为一种可能的实施方式,共振结构130还包括:共振膜136,设置在导音口132处。As shown in FIG. 4 and FIG. 5 , as a possible implementation manner, the resonant structure 130 further includes: a resonant film 136 disposed at the sound guide port 132 .

具体地,在共振结构的导音口132处设置有共振膜136,利用共振膜136和入射的声波的共振,达到阻抗匹配,提升整个共振结构130的吸声效率。Specifically, a resonant film 136 is provided at the sound guide port 132 of the resonant structure, and the resonance between the resonant film 136 and the incident sound wave is used to achieve impedance matching and improve the sound absorption efficiency of the entire resonant structure 130 .

其中,共振膜136的共振频率和需要吸声的特点的频段抑制,使得目标频段声波与共振膜136发生共振耦合。由于导音口132的小尺寸特性,可能导致声波在导音口132处的传播截面发生突变,影响阻抗匹配,通过在导音口132添加一层共振膜136,利用共振膜136与入射声波的共振,来达到阻抗匹配,提升共振结构130的吸声效率。Wherein, the resonant frequency of the resonant membrane 136 and the frequency band suppression that requires the characteristics of sound absorption make the sound wave of the target frequency band resonantly couple with the resonant membrane 136 . Due to the small size of the sound guide port 132, it may cause a sudden change in the propagation section of the sound wave at the sound guide port 132, which affects impedance matching. Resonance is used to achieve impedance matching and improve the sound absorption efficiency of the resonant structure 130 .

并且,共振膜136覆在导音口132处,共振膜136的材质可以为金属或者橡胶,固定方式可以利用胶水将共振膜136黏合固定于导音口132的内壁上。Moreover, the resonant film 136 covers the sound guide port 132 , the material of the resonant film 136 can be metal or rubber, and the fixing method can use glue to fix the resonant film 136 on the inner wall of the sound guide port 132 .

如图1和图4所示,作为一种可能的实施方式,出声口116位于前腔112的侧壁,共振结构130位于出声口116背离后腔114的一侧。As shown in FIGS. 1 and 4 , as a possible implementation, the sound outlet 116 is located on the side wall of the front chamber 112 , and the resonance structure 130 is located on the side of the sound outlet 116 away from the rear chamber 114 .

具体地,出声口116设置在前腔112的侧壁,并不正对发声单元120,进而高频声波可以在前腔112形成共振峰,拓展有效频带,提升扬声器100的发声效果。Specifically, the sound outlet 116 is set on the side wall of the front cavity 112 and is not facing the sound unit 120 , so that high-frequency sound waves can form a formant in the front cavity 112 to expand the effective frequency band and improve the sound effect of the speaker 100 .

并且,共振结构130设置在出声口116背离后腔114的一侧,由于声波的传递是有前腔112内通过出声口116向外部的,因此,将共振结构130设置在出声口116背离后腔114的一侧,可以更便于声波通过导音口132进入到导音通道134中,提升共振结构130对目标频段声波的吸收效果。And, the resonant structure 130 is arranged on the side of the sound outlet 116 away from the rear cavity 114, since the transmission of the sound wave is in the front cavity 112 through the sound outlet 116 to the outside, therefore, the resonant structure 130 is arranged on the sound outlet 116 The side away from the rear cavity 114 can make it easier for sound waves to enter the sound guide channel 134 through the sound guide port 132 , and improve the absorption effect of the resonant structure 130 on sound waves of the target frequency band.

以及,这样的设置方式使得共振结构130远离后腔114,降低共振结构130和后腔114之间的相互影响的可能性。And, such an arrangement makes the resonant structure 130 far away from the rear cavity 114 , reducing the possibility of mutual influence between the resonant structure 130 and the rear cavity 114 .

作为一种可能的实施方式,多个导音通道134沿着出声口到前腔的方向分布。As a possible implementation manner, multiple sound guide channels 134 are distributed along the direction from the sound outlet to the front cavity.

具体地,多个导音通道134沿着出声口到前腔的方向分布,使得整个共振结构130的厚度更薄,从而可以降低扬声器100的整体厚度,减少扬声器100的体积,并且,这样的共振结构130可以提升壳体110的厚度,提升扬声器100的结构强度。Specifically, a plurality of sound guide channels 134 are distributed along the direction from the sound outlet to the front cavity, so that the thickness of the entire resonant structure 130 is thinner, thereby reducing the overall thickness of the speaker 100 and reducing the volume of the speaker 100, and such The resonance structure 130 can increase the thickness of the casing 110 and increase the structural strength of the speaker 100 .

如图1和图4所示,作为一种可能的实施方式,导音口132设置在共振结构130朝向后腔114一侧。As shown in FIG. 1 and FIG. 4 , as a possible implementation manner, the sound guide port 132 is disposed on the side of the resonance structure 130 facing the rear cavity 114 .

具体地,导音口132设置在共振结构130朝向后腔114的一侧,也就是导音口132对着发声单元120,从而便于声波通过导音口132进入到导音通道134中,提升共振结构130对声波的吸收效果。Specifically, the sound guide port 132 is arranged on the side of the resonant structure 130 facing the rear cavity 114, that is, the sound guide port 132 faces the sound unit 120, so that sound waves can enter the sound guide channel 134 through the sound guide port 132 to enhance resonance. The absorption effect of the structure 130 on sound waves.

以及,这样的设置方式使得共振结构130远离后腔114,降低共振结构130和后腔114之间的相互影响的可能性。And, such an arrangement makes the resonant structure 130 far away from the rear cavity 114 , reducing the possibility of mutual influence between the resonant structure 130 and the rear cavity 114 .

作为一种可能的实施方式,多个导音通道134依次相连通,形成折弯状。As a possible implementation manner, a plurality of sound guiding channels 134 are sequentially connected to form a bent shape.

具体地,多个导音通道134依次相连通,位于端部的导音通道134和出声口116相连通,并且,多个导音通道134的整体形成折弯状,在同等的空间占用下,折弯状的导音通道134具有更长的传播距离,从而增加声波的反射次数,提升对目标频率声波的吸收效率,并且,不仅在导音口132会产生粘滞衰减,在折弯状的导音通道134的折弯处,也就是相邻导音通道134的连通处,也能够产生粘滞衰减,降低了等效声速,降低了共振频率,提升对目标频率声波的吸收性能,有利于降低频响曲线中的高频峰,提升扬声器100音频播放的效果。Specifically, a plurality of sound guiding channels 134 are connected sequentially, and the sound guiding channel 134 at the end is connected to the sound outlet 116, and the whole of the plurality of sound guiding channels 134 is bent, and the same space is occupied. , the curved sound guide channel 134 has a longer propagation distance, thereby increasing the number of reflections of sound waves, improving the absorption efficiency of sound waves of the target frequency, and not only viscous attenuation will occur at the sound guide port 132, but also in the bent shape The bend of the sound guide channel 134, that is, the connection of adjacent sound guide channels 134, can also produce viscous attenuation, reduce the equivalent sound velocity, reduce the resonance frequency, and improve the absorption performance of the sound wave of the target frequency. It is beneficial to reduce the high-frequency peak in the frequency response curve and improve the audio playback effect of the loudspeaker 100 .

具体地,在同等空间占用下,折弯状的导音通道134相对于亥姆霍兹腔体等结构,要具有更长的导音通道134,因此,想要做到同样的吸声效果,折弯状的导音通道134具有更小的体积,占用的空间更小,有利于扬声器100的小型化,有利于电子设备的轻薄化。其中,基于采用了折弯状的导音通道134,因此,共振结构130的厚度H最小仅为目标共振频率波长的二百分之一,这种深度亚波长的共振结构130能够在达到吸声效率的同时,有效减小结构厚度。Specifically, under the same space occupation, the curved sound-guiding channel 134 should have a longer sound-guiding channel 134 than structures such as Helmholtz cavity. Therefore, in order to achieve the same sound absorption effect, The bent sound guide channel 134 has a smaller volume and occupies less space, which is beneficial to the miniaturization of the speaker 100 and thinner and lighter electronic equipment. Among them, based on the use of the bent sound-guiding channel 134, the minimum thickness H of the resonant structure 130 is only 1/200th of the wavelength of the target resonant frequency. While improving the efficiency, the thickness of the structure is effectively reduced.

作为一种可能的实施方式,多个导音通道134的延伸方向相同。As a possible implementation manner, the extension directions of the plurality of sound guiding channels 134 are the same.

具体地,多个导音通道134的延伸方向相同,从而降低导音通道134的空间占用,可以使得共振结构小型化,减小扬声器100的体积。Specifically, the plurality of sound guiding channels 134 extend in the same direction, thereby reducing the space occupied by the sound guiding channels 134 , making the resonant structure miniaturized, and reducing the volume of the speaker 100 .

其中,多个导音通道134并排的分布,相邻的导音通道134在靠近到端部的位置设置开口,从而使得相邻的导音通道134相连通,并且,同一导音通道134和两侧的相邻的导音通道134相连通的位置,位于其两端处,从而多个导音通道134形成折弯状。Wherein, a plurality of sound guide channels 134 are distributed side by side, and adjacent sound guide channels 134 are provided with openings at positions close to the ends, so that adjacent sound guide channels 134 are connected, and the same sound guide channel 134 and two The position where the adjacent sound guiding channels 134 on the side are connected is located at both ends thereof, so that the plurality of sound guiding channels 134 form a bent shape.

具体地,共振结构130包括围板138、盖板140和隔板142,围板138设置在壳体110上,盖板140盖设在围板138上,使得壳体110、围板138和盖板140围成一个空间,在该空间内设置有隔板142,从而将该空间分隔为折弯状的导音通道134,也就是将一个较大的空间分隔为折弯状的导音通道134,以上方式可以降低共振结构130的制造难度。Specifically, the resonant structure 130 includes a surrounding plate 138, a cover plate 140 and a partition 142. The surrounding plate 138 is arranged on the housing 110, and the cover plate 140 is covered on the surrounding plate 138, so that the housing 110, the surrounding plate 138 and the cover The board 140 encloses a space, and a partition 142 is arranged in the space, so as to divide the space into bent sound-guiding channels 134, that is, to divide a larger space into bent-shaped sound-guiding channels 134 , the above method can reduce the manufacturing difficulty of the resonant structure 130 .

其中,隔板142的设置可以提升结构强度,增大系统的鲁棒性,降低了结构失效的可能性。Wherein, the setting of the partition plate 142 can improve the structural strength, increase the robustness of the system, and reduce the possibility of structural failure.

并且,隔板142采用硬质材料,例如塑料或金属等。Moreover, the separator 142 is made of hard material, such as plastic or metal.

围板138和隔板142可以是一体式结构,例如通过一体化注塑或者3D打印等技术先将围板138和隔板142制作出来,再将带有导音口132的盖板140粘合在围板138和盖板140上。The enclosure 138 and the partition 142 can be an integrated structure. For example, the enclosure 138 and the partition 142 are first produced by integrated injection molding or 3D printing technology, and then the cover 140 with the sound guide port 132 is bonded to the On the enclosure 138 and the cover 140.

如图2、图3和图5所示,其中,导音口132位于盖板140的一个角落,导音口132位于导音通道134的一端。As shown in FIG. 2 , FIG. 3 and FIG. 5 , the sound guide port 132 is located at a corner of the cover plate 140 , and the sound guide port 132 is located at one end of the sound guide channel 134 .

具体地,导音口132设置在盖板140的一个角落,也就是导音口132位于盖板140的一个角落,进而提升导音通道134的有效长度,提升对目标频段声波的吸收效率。Specifically, the sound guide port 132 is disposed at a corner of the cover plate 140 , that is, the sound guide port 132 is located at a corner of the cover plate 140 , thereby increasing the effective length of the sound guide channel 134 and improving the absorption efficiency of sound waves in the target frequency band.

具体地,前腔112中的声波通过盖板140一隅的导音口132进入由折弯状的折叠空间的多个导音通道134中,利用折弯状的结构不仅会在导音口132发生声波的粘滞损耗,同时在拐弯处也会发生粘滞损耗,而如亥姆霍兹共振腔的粘滞损耗大部分发生在导音口132附近。因此,在相同容积下,折弯状的导音通道134相比亥姆霍兹共振腔结构,具有着更大的粘滞损耗,意味着在相同频率点,折弯状的导音通道134对比相关技术中的共振结构130需要更小的空间,通过将折弯状的导音通道134的共振频率与扬声器100模组频响曲线中高频共振峰相匹配,降低共振峰强度,减小重放音乐中齿音部分声波能量,提升扬声器100的重放效果,同时也有效提升了电子设备的空间利用率。Specifically, the sound wave in the front cavity 112 enters the multiple sound-guiding channels 134 in the bent-shaped folded space through the sound-guiding opening 132 at the corner of the cover plate 140. The viscous loss of the sound wave also occurs at the corner, and most of the viscous loss of the Helmholtz resonant cavity occurs near the sound guide port 132 . Therefore, under the same volume, the bent sound guide channel 134 has a larger viscous loss than the Helmholtz cavity structure, which means that at the same frequency point, the bent sound guide channel 134 has a larger viscous loss than the Helmholtz cavity structure. The resonant structure 130 in the related art requires less space. By matching the resonant frequency of the bent sound-guiding channel 134 with the high-frequency formant in the frequency response curve of the speaker 100 module, the intensity of the formant is reduced, and the reproduction frequency is reduced. The sound wave energy of the sibilant part in the music improves the playback effect of the speaker 100 and effectively improves the space utilization rate of the electronic equipment.

由发声单元120的振膜振动产生的声波经过前腔112到达导音通道134,利用折弯状的多个导音通道134的共振吸声,降低频响曲线中的高频峰,降低音频中齿音部分能量,提升用户使用电子设备外放音频的使用体验。The sound waves generated by the vibration of the diaphragm of the sound unit 120 pass through the front cavity 112 and reach the sound guide channel 134, and use the resonant sound absorption of multiple bent sound guide channels 134 to reduce the high frequency peak in the frequency response curve and reduce the tooth sound in the audio Part of the energy improves the user experience of using electronic devices to play audio.

对比亥姆霍兹共振腔,本申请提供的扬声器100中的折弯状的多个导音通道134利用更小的容积降低了高频共振峰,不增加额外厚度的同时,提升电子设备的音频外放效果及对空间利用率,同时因为隔板142的存在增强了结构强度,提升了系统的鲁棒性,降低了结构的失效风险。Compared with the Helmholtz resonant cavity, the bent multiple sound-guiding channels 134 in the loudspeaker 100 provided by the present application use a smaller volume to reduce the high-frequency resonance peak, without adding additional thickness, and improve the audio frequency of the electronic device At the same time, because of the existence of the partition 142, the structural strength is enhanced, the robustness of the system is improved, and the risk of structural failure is reduced.
