In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 3, the embodiment of the present invention provides an acoustic hole 111 including: the sound outlet unit 1111 is formed by parallelly arranging a plurality of long round holes 11111 with different lengths, and the length of the long round hole 11111 in the middle of the sound outlet unit 1111 is greater than that of the long round holes 11111 at the two ends; several sound emitting units 1111 are arranged in the same line to form the sound hole 111.

Based on the above embodiment, each sound emitting unit 1111 is formed by arranging a plurality of long circular holes 11111 in parallel, and the shape of the regular sound emitting unit 1111 can reduce the reflection of sound waves to a certain extent and improve the sound emitting effect; meanwhile, the length of the long round hole 11111 in the middle is larger than that of the long round holes 11111 at the two ends, so that the whole sound emitting unit 1111 is in a shuttle shape and basically consistent with the shape of a loudspeaker of sound equipment, the area of the sound hole 111 corresponding to the sound is increased, and the sound volume is improved.

As shown in fig. 1 and 3, the embodiment of the present invention also provides an acoustic assembly 1 including: a sound box 11 having a front surface provided with the sound hole 111 in the first embodiment; the speaker 12 includes speakers 121, and the center of each speaker 121 corresponds to the middle of one sound emitting unit 1111.

Based on the above embodiment, when the sound box 12 is in operation, since the center of the speaker 121 is closer to the middle of the sound emitting unit 1111, the sound wave emitted by the speaker 121 and transmitted through the middle of the sound emitting unit 1111 is stronger, so that the long oblong hole 11111 is provided to emit sound, and the influence on sound quality due to diffraction caused by blocking of the sound wave is reduced; correspondingly, the distance between the center of the loudspeaker 121 and the two ends of the sound emitting unit 1111 is relatively long, and the sound wave emitted by the loudspeaker 121 and transmitted through the two ends of the sound emitting unit 1111 is relatively weak, so that the short long round hole 11111 is arranged to emit sound, and the influence on sound emitting definition due to the fact that the sound is relatively small due to the fact that the hole is too large is avoided; it should be noted that the number of the sound output units 1111 may be the same as the number of the speakers 121, or may be larger than the number of the speakers 121 in order to keep the surface hole shape consistent and ensure a certain aesthetic appearance of the surface of the sound box 11.

Preferably, as shown in fig. 1 and fig. 2, the back of the sound box body 11 further includes an accommodating cavity 112 for accommodating the sound box 12, and the sound box 12 is fixed in the accommodating cavity 112, so that on one hand, the overall volume of the sound box assembly 1 is reduced, and on the other hand, the distance from the sound box 12 to the sound box hole 111 is also shortened, which is beneficial to improving the volume and the sound definition.

Preferably, as shown in fig. 1, the above-mentioned sound assembly 1 further includes a sound fixture 13, which is provided with an installation groove 131 for installing sound; the sound 12 is fixed in the mounting groove 131 and indirectly fixed with the sound frame 11 through the sound fixing frame 13, when the sound 12 works, the generated vibration is transmitted into the sound frame 11 through the sound fixing frame 13, compared with the vibration generated by directly fixing the sound frame 11 and directly generating the vibration on the sound frame 11, the vibration absorption and vibration reduction effects of the sound fixing frame 13 can effectively reduce the vibration generated by the sound frame 11, thereby reducing the vibration of the sound hole 111 and improving the quality of the sound generated through the sound hole 111; preferably, the sound fixing frame 13 is a concave thin plate structure, so that the sound box fixing frame is convenient to mount and labor-saving, more mounting space is provided for the sound box 12, specifically, materials such as cast iron or chrome steel alloy can be adopted, and high-damping materials are utilized to effectively absorb vibration generated by the sound box 12 and transmitted to the sound box fixing frame 13.

Preferably, as shown in fig. 1, a sound guide hole 1311 is formed at the bottom of the mounting groove 131 at a position corresponding to the speaker 121, and the shape of the sound guide hole 1311 also corresponds to the shape of the speaker 121, so that the sound emitted from the speaker 121 can be transmitted to the sound hole 111 without being blocked by the sound fixing frame 13.

Preferably, as shown in fig. 1, the sound equipment enclosure 14 is further included, and the sound equipment enclosure 14 is fixed to the sound equipment chassis 11 so as to limit the sound equipment 12 in the accommodating cavity 112 of the sound equipment chassis 11, protect the internal circuit of the sound equipment 12, and suppress backward diffraction of sound waves, thereby achieving the sound gathering effect.

As shown in fig. 4, the embodiment of the present invention further provides a whiteboard all-in-one machine 2, which includes the sound component 1 mentioned in the above embodiment, when the sound component 1 is applied to the whiteboard all-in-one machine 2, the overall sound output quality is high, which can give a good hearing feeling to a user, and meanwhile, compared with an external sound device, the sound component has a lower cost and a better market prospect; of course, the acoustic assembly 1 described in the above embodiment is not limited to be applied to the whiteboard all-in-one machine 2, and may be applied to multimedia devices such as televisions and computers to produce the same effect.

In summary, the specific installation process of the acoustic assembly 1 includes aligning the speaker 121 of the acoustic 12 with the sound guide hole 1311 of the acoustic mount 13, and then fixing the acoustic 12 with the acoustic mount 13; then, the sound fixing frame 13 is fixed in the accommodating cavity 112 of the sound box body 11, and the center of the loudspeaker 121 of the sound 12 is kept corresponding to the middle of the sound outlet unit 1111 of the sound hole 111 on the surface of the sound box body 11; finally, the acoustic enclosure 14 is fixed to the back of the acoustic enclosure 11.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
