Description

[0001] This application is a divisional application of the invention patent application with the application number 201910894078.5, the application date of September 20, 2019, and the invention creation name of "Electronic Device", which was submitted to the China National Patent Office. Technical Field

[0002] The present invention relates to the technical field of speakers, and in particular to an electronic device. Background Art

[0003] Speakers are sound - emitting components set in many multimedia electronic devices such as televisions, tablet computers, and touch - all - in - one machines, and are important components related to the user experience. The position of the speaker sound outlet directly affects the final sound quality of the speaker. In the prior art, the sound outlet of the speaker is generally set on the front or below of the electronic device; if the sound outlet is set on the outer side of the bottom frame of the multimedia electronic device, the sound wave will first be emitted to the ground and then reflected to the human ear, thus greatly affecting the sound quality. Therefore, the sound outlet is mostly set on the front for display of the multimedia electronic device to significantly improve the sound quality.

[0004] Figure 1 For the structural schematic diagram of the speaker in the electronic device in the prior art; as Figure 1 shown, the electronic device 1000 can be, for example, a television, which includes a display screen and a housing assembly.

[0106] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention.

[0107] All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0108] A speaker is a sound - generating component provided in many multimedia electronic devices such as televisions, tablet computers, and touch - all - in - one machines, and is an important component related to the user experience. Generally, the front side of an electronic device facing the user is mainly a display area. If the sound outlet of the speaker is set on the front side of the electronic device, it is necessary to appropriately increase the width of the border. At this time, if the area of the display area is to be maintained, the overall volume of the machine will increase; if the overall volume of the machine is not to be increased, a part of the display area will be occupied. In the prior art, there is no solution that can achieve front - facing sound output without increasing the border width and without occupying the area of the display area.

[0109] To solve the above problems, the present application provides a sound - guiding device, a sound - guiding component, and an electronic device having the sound - guiding component. Among them, Figure 2 is a schematic diagram of the structure of a speaker in an electronic device according to an embodiment of the present invention; Figure 3 is a schematic diagram of the structure of a sound - guiding component in a first perspective according to an embodiment of the present invention; Figure 4 is a schematic diagram of the structure of a sound - guiding component in a second perspective according to an embodiment of the present invention; Figure 5 is an exploded view of a sound - guiding component according to an embodiment of the present invention; Figure 6 is a schematic diagram of the structure of a sound - guiding component after removing the front shell of the sound - guiding device according to an embodiment of the present invention; Figure 7 is a schematic diagram of the structure of a sound - guiding device according to an embodiment of the present invention.

[0110] First, the names involved in the present application are described:

[0111] "Installation reference plane" refers to a reference plane that can be used as a reference plane when the electronic device is installed, and this reference plane is perpendicular to the display surface of the electronic device. For example, when the electronic device needs to be installed vertically, the installation reference plane should be a horizontal plane, and the bottom of the entire electronic device after installation just touches this horizontal plane, and the display surface is set vertically, and the display surface is perpendicular to this installation reference plane.

[0112] "Vertical" refers to the direction perpendicular to the installation base surface. Due to the relationship definition between the aforementioned display surface and the reference surface, it can be determined that the display surface extends along the vertical direction.

[0113] As Figure 2 shown, an embodiment of the present embodiment provides an electronic device 2000, including a display component, a housing, a main board disposed in the housing, and various accessories (such as speakers, display indicators, various interfaces, etc.). The display component includes a backlight module 2500 and a display screen 2600. The backlight module 2500 is disposed on the front surface of the housing. An accommodation cavity 2100 is formed between the backlight module 2500 and the back surface of the housing. A speaker bracket 2400 and a sound guiding component are disposed in the accommodation cavity 2100. The sound guiding component includes a speaker 2200 and a sound guiding device 2300. The speaker 2200 is disposed on one side of the accommodation cavity 2100 close to the lower frame 2700 of the housing. The speaker 2200 is fixedly disposed on the speaker bracket 2400. Specifically, the fixing of the speaker 2200 can be achieved by means of hoisting in cooperation with bolt connection or clamping. For example, a card slot for fixing the speaker 2200 can be provided on the speaker bracket 2400, and the through-hole clamping portion at the upper end of the speaker 2200 is fixed in the card slot.

[0114] The sound guiding device 2300 includes a sound receiving portion 2310 for connecting with the speaker 2200 and a sound guiding body 2320 for guiding out sound; an incoming sound port 2311 is provided on the end surface of the sound receiving portion 2310, and an outgoing sound port 2321 is provided at the end of the sound guiding body 2320 facing away from the sound receiving portion 2310; the bottom of the sound guiding body 2320 is located on an installation reference surface 3000, the sound receiving portion 2310 and the sound guiding body 2320 are on the same side of the installation reference surface 3000, and the bottom of the sound receiving portion 2310 is located within the installation reference surface 3000 or at a preset distance from the installation reference surface 3000; the vertical height of the end of the sound guiding body 2320 is less than the vertical height of the sound receiving portion 2310.

[0115] Among them, the vertical height refers to the height in the direction perpendicular to the installation reference surface 3000.

[0116] Specifically, the speaker 2200 may specifically include a speaker housing 2210 and a speaker 2220 disposed at the lower part of the speaker housing 2210, and sound is emitted from the speaker. The structure of the sound receiving part 2310 can cooperate with the side of the speaker housing where the speaker is provided. Specifically, the sound receiving part 2310 may be formed at the starting end of the sound guiding body 2320 and have an end face 2312 that cooperates with the surface of the speaker housing 2210 on the side where the speaker is provided. An sound inlet 2311 is provided on the end face 2312. The sound receiving part 2310 abuts against the surface of the speaker housing 2210 through the end face 2312 and aligns the sound inlet 2311 with the speaker 2220, and the sound receiving part 2310 and the speaker housing 2210 can be connected together by screws 2313 or snap connections. A sound cavity is formed in the sound guiding body 2320, and the sound cavity communicates with the sound inlet 2311. In this way, all the sound output by the speaker can be transmitted to the sound outlet through the sound inlet.

[0117] The end face of the sound receiving part 2310 is provided with a sound inlet 2311, and the end of the sound guiding body 2320 facing away from the sound receiving part 2310 is provided with a sound outlet 2321. One end of the sound cavity in the sound guiding body 2320 communicates with the sound inlet, and the other end communicates with the sound outlet. Thus, the sound emitted by the speaker 2220 is output after being led out to the sound outlet through the sound cavity in the sound guiding body 2320.

[0118] Both the sound receiving part 2310 and the sound guiding body 2320 are located on the same side of the installation reference plane 3000. In this embodiment, the installation reference plane 3000 is Figure 2 a horizontal plane shown in the figure. Among them, the bottom of the sound receiving part 2310 may be located on the installation reference plane 3000 (that is, the lowest point or line or surface of the sound receiving part is located within the installation reference plane), or there is a preset distance from the installation reference plane 3000; the bottom of the sound guiding body 2320 may be located on the installation reference plane 3000 (that is, the lowest point or line or surface of the sound guiding body is located within the installation reference plane). The end face of the sound receiving part 2310 connecting the speaker 2200 and the end face of the sound guiding body 2320 (that is, the end of the sound guiding body facing away from the sound receiving part) may be parallel or have a certain angle, so that the sound inlet and the sound outlet are parallel or have the said certain angle, and this embodiment does not limit this. And, in this embodiment, the vertical height of the end of the sound guiding body 2320 is less than the vertical height of the sound receiving part 2310. In other words, according to the previous definition of "vertical", it means that in the direction perpendicular to the basic plane 3000, the height of the end of the sound guiding body provided with the sound outlet is less than the height of the sound receiving part provided with the sound inlet. And the heights here respectively refer to the maximum dimension in the vertical direction of the outer contour of the end of the sound guiding body, and the maximum dimension in the vertical direction of the outer contour of the sound receiving part.

[0119] It should be noted that the specific shape of the sound conductor 2320 is related to the positions of the sound receiving part 2310 and the sound outlet 2321; at the same time, the relative positions of the components inside the electronic device are fully considered to optimize the layout. However, no matter how the layout is further optimized, by setting the vertical space occupied by the end of the sound conductor 2320 with the sound inlet to be smaller than the vertical space occupied by the sound receiving part, it is possible to set the sound outlet on the front side of the frame and the display surface, thereby ensuring better sound quality. At the same time, since the vertical space occupied is very small, the design requirements of the narrow frame can be fully met, so that the overall space occupied by the electronic device is smaller, and the user is more convenient to install and use, while the display area of ​​the electronic device is not affected.

[0120] When the electronic device layout adopts the sound-conducting device provided in this embodiment, the speaker 2200 can be set in the space enclosed by the rear side of the display screen and the shell, or in the space of the bottom of the display screen near the rear shell. These positions have more space not used by other components, and will not lead to an increase in the overall volume of the electronic setting. The sound of the speaker is further transmitted to the front of the display surface by the sound-conducting device of this embodiment to ensure the sound quality effect, thus overcoming the difficulty of taking into account the layout, sound quality effect and narrow frame design at the same time. The specific height of the frame 2000 on the front of the electronic device is limited by the height of the sound outlet 2321. Preferably, the electronic device adopting the sound-conducting device 2300 of this embodiment can make the frame height 1.5-5mm while ensuring the volume and sound quality of the front sound, thereby realizing a visually ultra-thin frame.

[0121] Since the sound-conducting device 2300 is added to the electronic device, the sound-conducting device can conduct sound and thus enhance the sound waves emitted by the speaker 2200, thereby increasing the propagation distance of the sound waves.

[0122] In an optional implementation, the projection width of the sound inlet 2311 in the installation reference plane 3000 is smaller than the projection width of the sound outlet 2321 in the installation reference plane 3000, wherein the projection width refers to Figure 2 The length perpendicular to the paper.

[0123] Through the above arrangement, the sound waves can be propagated gradually from a narrow space to a wider space in the sound guiding device 2300, thereby improving the propagation range of the sound waves and the directionality of the sound propagation.

[0124] Furthermore, the sound guide 2320 in this embodiment includes a first part 2322 and a second part 2323 connected to each other, the first part 2322 is connected to the sound receiving part 2310 , and the sound outlet 2321 is arranged on a side of the second part 2323 away from the first part 2322 .

[0125] Among them, the vertical height of the first part 2322 on the installation reference plane 3000 gradually decreases from the sound inlet 2311 to the sound outlet 2321, and the vertical height of the first part 2322 on the installation reference plane 3000 is greater than or equal to the vertical height of the second part 2323 within the installation reference plane 3000.

[0126] The projected width of the first part 2322 within the installation reference plane 3000 gradually increases from the sound inlet 2311 to the sound outlet 2321, and the projected width of the first part 2322 within the installation reference plane 3000 is less than the projected width of the second part 2323 within the installation reference plane 3000.

[0127] By setting the vertical height of the first part 2322 into a gradually decreasing structure, the sound wave can be compressed in the vertical direction. By setting the width of the first part 2322 into a gradually increasing structure, a smooth transition can be achieved on the inner surface of the first part 2322, avoiding dead corners, which is beneficial to the transmission of sound waves within the sound guide 2320 and reduces the volume loss during propagation.

[0128] Optionally, in this embodiment, the vertical height of the second part 2323 on the installation reference plane 3000 is equal everywhere. Optionally, the vertical height of the second part 2323 on the installation reference plane 3000 gradually changes along a certain direction, and the specific situation depends on the engineering implementation; the projected width of the second part 2323 within the installation reference plane 3000 is equal everywhere, or approximately equal, or gradually changes in a certain direction, and the specific situation depends on the engineering implementation.

[0129] Optionally, setting the second part 2323 into the above-mentioned generally cuboid-like structure can facilitate the processing of the accommodation cavity 2100 of the electronic device, reduce the processing difficulty, improve the production efficiency, and at the same time facilitate its installation on the electronic device.

[0130] In this embodiment, a shock-absorbing foam 2330 is further provided on the outer edge of the sound outlet 2321 and a speaker net 2340 is provided at its mouth. Among them, the shock-absorbing foam 2330 surrounds the outer wall of the sound outlet 2321 and can be adhesively bonded to the outer wall of the sound outlet 2321 by means such as adhesion for reducing the mechanical vibration between the speaker and the electronic device; the speaker net 22340 is arranged at the end of the sound outlet 2321. Through the above settings, the functions of shock absorption and uniform sound conduction can be achieved.

[0131] Furthermore, the sound guide device of this embodiment further includes an equalizer 2350. The sound inlet 2351 of the equalizer 2350 is connected to the sound inlet 2311, and the equalizer 2350 is used for uniformly transmitting the sound emitted by the speaker 2200.

[0132] That is, the sound inlet 2351 of the equalizer communicates with the sound inlet 2311 of the sound receiving part 2310, and the sound outlet 2352 of the equalizer communicates with the sound outlet 2321 of the sound guiding body 2320. Among them, there may be a certain angle, such as ninety degrees, between the sound inlet 2351 and the sound outlet 2352 of the equalizer. That is, in this embodiment, the equalizer 2350 can compress the sound emitted by the speaker 2200 in the vertical direction and diffuse it in the horizontal direction. The equalizer 2350 can be arranged on one side of the sound guiding body 2320 close to the sound receiving part 2310, and specifically can be arranged in the first part 2322 of the sound guiding body 2320.

[0133] A plurality of sound guiding plates 2353 are arranged in the sound inlet 2351 of the equalizer. The intervals between adjacent two sound guiding plates 2353 are equal, and the gaps between adjacent two sound guiding plates 2353 form the sound inlet holes of the equalizer. By arranging the uniformly distributed sound guiding plates 2353, sound waves of various frequencies can be uniformly distributed in the equalizer 2350, so that the sound waves enter the sound guiding body 2320 uniformly, and the consistency of the volume at each part in the sound guiding body 2320 is realized.

[0134] In this embodiment, the equalizer 2350 and the first part 2322 can be integrally injection-molded. A plurality of draft holes 2354 are also arranged on the equalizer 2350, so as to facilitate the implementation of the molding process. The sound outlet 2352 of the equalizer is formed between adjacent two draft holes 2354.

[0135] Specifically, Figure 5 is an exploded view of the sound guiding assembly provided by an embodiment of the present invention; please refer to Figure 5 . In an optional embodiment, the sound guiding device 2300 of this embodiment can be composed of two parts. The sound guiding device 2300 includes a front shell 2360 of the sound guiding device and a rear shell 2370 of the sound guiding device. The sound guiding plate 2353 can be arranged on either the front shell 2360 of the sound guiding device or the rear shell 2370 of the sound guiding device. In this embodiment, it can be arranged on the rear shell 2370 of the sound guiding device. The front shell 2360 of the sound guiding device and the rear shell 2370 of the sound guiding device are connected and fixed by a snap connection method, so as to facilitate installation and disassembly.

[0136] Specifically, the front shell 2360 and the rear shell 2370 of the sound guiding device in this embodiment are provided with matching clamping parts.

[0138] As Figure 8 shown, another embodiment of the present embodiment provides an electronic device 4000, including a housing. A receiving cavity 4100 is provided at the lower end of the housing. A sound guiding component is provided in the receiving cavity 4100. The sound guiding component includes a speaker 4200 and a sound guiding device 4300. The sound guiding device 4300 is generally L-shaped in the Figure 8 shown direction. The sound guiding device 4300 includes a sound input part 4310 and a sound output part 4320. The sound input part 4310 and the sound output part 4320 are communicated. The sound input port 4311 of the sound input part 4310 and the sound output port 4321 of the sound output part 4320 are arranged side by side. The height at the sound input port 4311 of the sound input part 4310 is greater than the height at the sound output port 4321 of the sound output part 4320.

[0139] Specifically, as Figures 8 - 12 shown, the electronic device 4000 generally includes a backlight module 4500 arranged in the housing and a display 4600 arranged on the surface of the housing. The backlight module 4500 is arranged at one end of the housing close to the display 4600. A receiving cavity 4100 is formed between the backlight module 4500 and the other end of the housing. A speaker bracket 4400 and a speaker 4200 are provided in the receiving cavity 4100. The speaker 4200 is arranged on one side of the receiving cavity 4100 close to the lower border 4700 of the housing. The speaker 4200 is fixedly arranged on the speaker bracket 4400. Specifically, the fixing of the speaker 4200 can be realized by means of hoisting, bolt connection, clamping or the like.

[0140] Specifically, the speaker 4200 may include a speaker housing 4210 and a speaker 4220 arranged at the lower part of the speaker housing 4210. The sound input port of the sound guiding device 4300 is connected to the speaker 2220, so as to conduct the sound emitted by the speaker 2220.

[0141] The sound guiding device 2300 is bent into an L shape. The included angle between the upper surface of the sound input part 4310 and the upper surface of the sound output part 4320 is greater than or equal to ninety degrees. That is, from Figure 8Viewed from the shown angle, the sound input part 4310 and the sound output part 4320 are connected to form an approximately L shape, that is, along the thickness direction of the electronic device, the height of the sound guiding device 2300 gradually decreases to form an L shape; or the height of the sound guiding device 2300 is stepped somewhere in the middle to form an L shape, such as the connection part of the sound input part 4310 and the sound output part 4320 is stepped. The sound guiding device 4300 includes a sound input part 4310 for guiding sound in and a sound output part 4320 for guiding sound out. Among them, the sound input part 4310 is located on the right side of the sound guiding device 4300 in the shown plane, and the sound output part 4320 is located on the left side of the sound guiding device 4300 in the shown plane. The sound input part 4310 and the sound output part 4320 are communicated to realize the propagation of sound.

[0142] In this embodiment, the sound input port 4311 of the sound input part 4310 is parallel to the sound output port 4321 of the sound output part 4320, so as to ensure the horizontal propagation of sound; at the same time, the height of the sound input part 4310 at the sound input port 4311 is greater than the height of the sound output part 4320 at the sound output port 4321, so that the height occupied by the sound output part at the sound output port 4321 is lower, and the sound output port can be arranged on the front side on the same side as the frame and the display surface, ensuring better sound quality. At the same time, because the vertical space occupied is very small, it can fully meet the design requirements of a narrow bezel. On the premise that the display area of the electronic device is not affected, the overall space occupied by the electronic device is smaller, and it is more convenient for users to install and use. The sound input port 4311 of the sound input part 4310 is parallel to the sound output port 4321 of the sound output part 4320, and the height of the sound input part 4310 at the sound input port 4311 is greater than the height of the sound output part 4320 at the sound output port 4321, mainly to ensure that the sound propagates horizontally without change while having a large drop in the height direction, which is convenient to make the speaker outlet into a long strip-shaped micro slit on the front of the electronic device. In this embodiment, the sound input port 4311 of the sound input part 4310 and the sound output port 4321 of the sound output part 4320 are parallel to each other, specifically referring to that the sound input port 4311 of the sound input part 4310 and the sound output port 4321 of the sound output part 4320 are arranged side by side. When specifically implemented in engineering, the sound input port 4311 of the sound input part 4310 and the sound output port 4321 of the sound output part 4320 can be arranged in parallel, or the sound input port 4311 of the sound input part 4310 and the sound output port 4321 of the sound output part 4320 can be slightly inclined, as long as it does not affect the horizontal propagation of sound.

[0143] When arranging the electronic device adopting the sound guiding device provided in this embodiment, the speaker 4200 can be arranged in the space enclosed by the rear side of the display screen and the housing, or in the space at the rear part of the bottom of the display screen close to the housing. There is more unused space at these positions and it will not cause an increase in the overall volume of the electronic device. Further using the sound guiding device in this embodiment to transmit the sound of the speaker to the front where the display surface is located can ensure the sound quality effect and overcome the problem that it is difficult to balance the layout, sound quality effect and narrow bezel design at the same time. The specific height of the front bezel of the electronic device is limited by the height of the sound outlet 4321. Preferably, for the electronic device adopting the sound guiding device 4300 in this embodiment, while ensuring the volume and sound quality of the front sound output, the height of the bezel can be made 1.5 - 5 mm, achieving a visually ultra-thin bezel.

[0144] Adopting the solution of this embodiment, the sound guiding device 4300 can also enhance the sound wave emitted by the speaker 2200, thereby increasing the propagation distance of the sound wave.

[0145] The sound guiding device in this embodiment will be further described in detail below.

[0146] The height of the sound guiding device 4300 decreases along the direction from the sound inlet 4311 of the sound inlet part 4310 to the sound outlet 4321 of the sound outlet part 4320.

[0147] Specifically, in the above embodiment, the height of the sound inlet part 4310 decreases along the direction from the sound inlet 4311 of the sound inlet part 4310 to the sound outlet 4321 of the sound outlet part 4320.

[0148] Through the above settings, the sound can gradually converge in the sound guiding device 4300, achieving the effect of enhancing the sound effect; at the same time, since the height of the sound guiding device 4300 gradually decreases, the sound is first compressed, and the energy of the sound is concentrated. At the same time, the inner surface of the sound guiding device 4300 can achieve a smooth transition, avoiding dead ends, which is beneficial to reducing the volume loss during propagation.

[0149] In this embodiment, the sound outlet part 4320 is flat, which is beneficial to enhancing the sound effect.

[0150] Specifically, as Figure 8 shown, the above flat shape means that the overall thickness of the sound outlet part 4320 is less than the thickness of the sound inlet part 4310. For example, the thickness of the sound outlet part 4320 can be kept unchanged along the direction from the sound inlet 4311 of the sound inlet part 4310 to the sound outlet 4321 of the sound outlet part 4320. Such a setting is beneficial to the transmission of sound and is convenient for processing the supporting structure on the electronic device.

[0151] The sound outlet 4320 in this embodiment can be in the shape of a flat horn, which is conducive to the diffusion of sound and enhances the sound effect. The sound outlet 4320 is in the shape of a flat horn, which constitutes a horn, compresses the gathered sound, and then amplifies it through the flat horn-shaped sound outlet 4320, thereby improving the sound effect and the directionality of the sound.

[0152] The sound guiding device 4300 is also provided with an equalizer 4330, the sound inlet 4331 of the equalizer communicates with the sound inlet 4311 of the sound inlet portion 4310, and the sound outlet 4332 of the equalizer communicates with the sound outlet 4321 of the sound outlet portion 4320. The equalizer 4330 can evenly distribute the sound entering the sound guiding device 4300 into the sound guiding device 4300.

[0153] Specifically, the equalizer sound inlet 4331 includes at least two spaced sound inlet holes 43310, the sound inlet holes 43310 communicate with the sound inlet 4311 of the sound inlet portion 4310, and a first sound guide channel is formed between the sound inlet holes 43310 and the equalizer sound outlet 4332. The sound entering the equalizer 4330 passes through different first sound guide channels and is evenly transmitted to various places inside the sound guide device 4300.

[0154] Furthermore, the sound inlet hole 43310 is a vertically arranged sound inlet slit. The sound inlet hole 43310 is a vertically arranged sound inlet slit, which can better even out the sounds of various frequencies and can preliminarily compress the sounds.

[0155] In this implementation, the equalizer 4330 includes at least two sound guiding structures 4333 , and a sound inlet hole 43310 and a first sound guiding channel are formed between adjacent sound guiding structures 4333 .

[0156] Specifically, the sound guiding structure 4333 includes a first plate 43331 and inclined partitions 43332 respectively arranged on both sides of the first plate 43331, and the first plate 43331 and the inclined partitions 43332 respectively arranged on both sides of the first plate 43331 form a triangle shape.

[0157] The first plate 43331 and the inclined partitions 43332 respectively arranged on both sides of the first plate 43331 surround to form a hollow triangular prism with a draft hole 4334. The draft hole 4334 can facilitate processing and improve processing efficiency.

[0158] Further, the adjacent first plate members 43331 form the sound inlet hole 43310 of the equalizer, and the included angle between the adjacent inclined partition plates 43332 forms the sound outlet 4332 of the equalizer. The included angle between the two inclined partition plates 43332 is an acute angle, so the width of the sound inlet hole 4331 of the equalizer is smaller than the width of the sound outlet 4332 of the equalizer. The sound preliminarily compressed through the sound inlet hole 43310 is further compressed in the first half of the first sound guiding channel. At the same time, since the width of the sound inlet hole 4331 of the equalizer is smaller than the width of the sound outlet 4332 of the equalizer, it can be known that the outlet of the first sound guiding channel is larger than the inlet, making the entire first sound guiding channel in a horn shape, so that the compressed sound has a preliminary sound amplification effect after being transmitted in the first channel. Then it enters the flat horn-shaped sound outlet part 4320 for further sound amplification, so as to further enhance the sound effect and the sound directivity.

[0159] In this embodiment, the sound inlet hole 43310 and the sound outlet 4332 of the equalizer can be perpendicular to each other, so as to enhance the sound compression effect.

[0160] The height of the lower surface at the sound inlet hole 4331 of the equalizer is greater than the height of the lower surface at the sound outlet 4321 of the sound outlet part 4320, increasing the height difference between the sound inlet hole 4331 of the equalizer and the sound outlet 4321 of the sound outlet part 4320, which is convenient for making the thickness of the sound outlet part 4320 thinner.

[0161] Through the above settings, the sound wave propagates gradually from a narrower space to a wider space in the equalizer, thereby increasing the propagation range of the sound wave.
