It should also be understood that the term "and / or" used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0044] The acoustic device of this specification is described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0045] See also Figure 1 and Figure 2 As shown, an embodiment of this specification provides an acoustic device 100, which can be an audio product such as a smart speaker, and can be applicable to acoustic design projects such as mobile screens. The acoustic device 100 may include: a support structure 10, a display screen 20, and a sound module. The display screen 20 can be movably arranged on the support structure 10. The sound module includes a plurality of sound units 30. Among them, at least part of the sound units 30 are distributed on the support structure 10, and another part of the sound units 30 are distributed on the display screen 20. Optionally, the display screen 20 can be a smart screen with touch functions. The sound unit 30 can be a speaker.

[0046] It can be seen from the above technical solutions that the acoustic device 100 of this specification achieves a more all-round sound package by distributing the sound units on the support structure 10 and the display screen 20, solving the problems of sound-image separation, unclear human voice, and dark timbre. The distributed stacking design is adopted to realize the surface acoustic design of the display screen 20, produce a better sound experience, and better solve the poor visual experience of sound-image separation of existing market products, and enhance the user's viewing experience. The acoustic development of a new category of speakers is realized, bringing a better sound experience and giving users a better acoustic experience. In addition, the sound unit is not blocked by the screen, avoiding the situation in the related technology where the front sound is small and the back sound is large at the same volume due to the single speaker position setting.

[0047] The acoustic device of this manual adopts the above-mentioned distributed innovative architecture design, which can solve the following problems:

[0048] 1) Solve the problem that the sound from the front of the mobile screen product is low, the sound from the back is loud, the human voice is unclear, and the tone is dark.

[0049] 2) Solve the problem of poor viewing experience caused by the separation of sound and picture in mobile screen products.

[0050] See also Figure 3 As shown, in some optional embodiments, the plurality of sound emitting units 30 include at least one first sound emitting unit 31, at least one second sound emitting unit 32, and at least one third sound emitting unit 33, and the audio emitted by the first sound emitting unit 31 and the audio emitted by the second sound emitting unit 32 are both smaller than the audio emitted by the third sound emitting unit 33. The first sound emitting unit 31 and the second sound emitting unit 32 are both disposed on the support structure 10, and the third sound emitting unit 33 is disposed on the display screen 20.

[0051] In this way, the first sound unit 31, the second sound unit 32 and the third sound unit 33 for emitting different audio frequencies are distributed at different positions of the acoustic device to form an acoustic design of a surface sound field, achieve a more all-round sound wrapping, and have a better sense of sound image and sound field envelopment.

[0052] Optionally, the audio emitted by the first sound unit 31 is smaller than the audio emitted by the second sound unit 32. It can be understood that the first sound unit 31 can be used to achieve bass sound effects (low frequency part below 200Hz). The second sound unit 32 can be used to achieve mid-range audio effects (mid-frequency part 200Hz-3kHz). The third sound unit 33 can be used to achieve treble audio effects (high frequency part above 3kHz). In this embodiment, the first sound unit 31 is one, which is arranged at the lower half of the support structure 10, and the sound direction is directed upward to achieve the sound effect of a subwoofer. The second sound unit 32 is one, which is arranged at the top of the support structure 10 and the sound direction is directed upward to achieve the sound effect of sky sound, solve the problem of human voice being backward and dark, and solve the problem of viewing loudness. There are four third sound units 33, which can be distributed around the display screen 20, such as four sides or four corners, so that the display screen can achieve stereo sound effects in both horizontal and vertical screen states. It should be noted that the third sound-emitting unit 33 can be set according to actual needs, and this specification does not limit this.

[0053] In this way, the acoustic equipment can adopt a 3.1-channel three-way distributed design, with sound output around the display screen to ensure mid- and high-frequency effects; the sound output from the top of the bracket structure realizes the sky sound effect and enhances the mid-frequency hearing sense; the sound output from the lower half of the bracket structure realizes the acoustic effect design of the subwoofer, thereby achieving a more all-round sound package. It solves the problems of sound and picture separation, unclear mid-frequency human voice, and dark timbre, while the bass provides a strong and shocking low-frequency effect. It should be noted that three-way refers to the sound of low frequency, mid-frequency, and high frequency in three speaker systems. 3.1 channels refer to the acoustic system consisting of a left channel and a right channel of two-channel stereo + a mid-range channel + a bass channel.

[0054] In some optional embodiments, the support structure 10 includes a base 11 and a support assembly 12, and the support assembly 12 is connected to the top of the base 11. The first sound unit 31 is arranged on the side of the base 11 facing the display screen 20. The second sound unit 32 is arranged on the support assembly 12. The display screen 20 is movably arranged on the support assembly 12.

[0055] In this way, the first sound unit 31 and the second sound unit 32 for emitting different audio frequencies are distributed at different positions of the bracket assembly 12 to form an acoustic design of a surface sound field, achieve a more all-round sound wrapping, and have a better sense of sound image and sound field envelopment.

[0056] Optionally, the display screen 20 is rotatably disposed on the support assembly 12. Figure 1 and Figure 2As shown, the display screen 20 can rotate relative to the bracket assembly 12 to switch between the horizontal screen and the vertical screen to meet the different viewing needs of users. In this way, the following automatic switching function of the left and right channels can be realized after the screen is rotated by using a distributed design: after the display screen is rotated, the left and right channels can be automatically switched by switching the left and right signal input channels of the distribution amplifier.

[0057] The acoustic device of this specification, each sound unit is arranged according to the above-mentioned distributed stacking design, realizing the acoustic design of the intelligent mobile screen, solving the ID requirements of the full screen of such products, and can bring a higher screen-to-body ratio to mobile screen projects, while realizing an ultra-thin screen design. At the same time, the sound and screen are at a level of 0 degrees, reaching the human ear directly, improving the viewing experience. Through the distributed stacking of each sound unit, the objective effect of excellent loudness and better mid-high frequency extension can be achieved. When used in the near field, the acoustic effect of point sound field-surface sound field is achieved, which can provide a better sound image and sound field surround.

[0058] In this embodiment, there is one first sound unit 31, which is disposed at the lower half of the bracket assembly 12 and emits sound upward to achieve the sound effect of a subwoofer. There is one second sound unit 32, which is disposed at the top of the bracket assembly 12 and emits sound upward to achieve the sound effect of sky sound, solve the problem of human voice being biased backward and dark, and solve the problem of loudness when watching.

[0059] In some optional embodiments, the support assembly 12 includes a first support 13 and a second support 14, the first support 13 is connected to the base 11 along a first direction Y, and the second support 14 is connected to the first support 13 along a second direction X. The second direction X intersects with the first direction Y. The second sound unit 32 is disposed on at least one of the first support 13 and the second support 14, and the display screen 20 is movably disposed on the second support 14. In this embodiment, the first direction Y and the second direction X are perpendicular. The display screen 20 is rotatably disposed on the second support 14, and can be rotated relative to the support assembly 12 to switch between horizontal and vertical screens to meet different viewing needs of users.

[0060] In this way, the second sound unit 32 can be distributed at various positions of the first bracket 13 and the second bracket 14 of the bracket assembly 12 to form an acoustic design of a surface sound field, achieve a more all-round sound wrapping, and have a better sense of sound image and sound field envelopment.

[0061] In some optional embodiments, the audio frequency emitted by the first sound emitting unit 31 is smaller than the audio frequency emitted by the second sound emitting unit 32. It can be understood that the first sound emitting unit 31 can be used to achieve a bass sound effect, and the second sound emitting unit 32 can be used to achieve a mid-range audio effect.

[0062] Among them, see Figure 3 As shown, in the present embodiment, the second sound-emitting unit 32 is one and is arranged at the top of the first bracket 13, and the sound-emitting direction is upward, so as to realize the sound effect of sky sound, solve the problem of the human voice being biased backward and dark, and solve the problem of loudness when viewing.

[0063] Alternatively, see Figure 4 As shown, in this embodiment, there are multiple second sound-emitting units 32, one of which is arranged at the top of the first bracket 13, and the sound-emitting direction is upward, so as to achieve the sound effect of the sky sound coming out upward, solve the problem of the human voice being biased backward and dark, and solve the problem of the loudness of the viewing. At least one other is arranged on the second bracket 14. Optionally, two second sound-emitting units 32 are arranged on the second bracket 14, one of which is emitting sound upward (i.e., the speaker is output upward), and the other is emitting sound downward (i.e., the speaker is output downward), so as to enhance the effect of the sky sound and achieve a better mid-frequency performance.

[0064] Alternatively, see Figure 5 As shown, in this embodiment, there are multiple second sound-emitting units 32, one of which is arranged at the top of the first bracket 13, and at least one is arranged on the second bracket 14. In addition, at least one is arranged on the side of the middle section of the first bracket 13 facing the display screen 20. In this way, by adding a forward-facing mid-range speaker, the human voice can reach the human ear better, so that the sound effect can reach the human voice directly to achieve better mid-frequency performance. Optionally, two second sound-emitting units 32 are arranged on the second bracket 14, one of which emits sound upward (that is, an upward speaker), and the other emits sound downward (that is, a downward speaker), so as to enhance the effect of sky sound and achieve better mid-frequency performance.

[0065] In some optional embodiments, the first direction Y is a vertical direction, the second direction X is a horizontal direction, and the second bracket 14 is liftably connected to the first bracket 13 to achieve a lifting and lowering adjustment effect on the display screen 20. Optionally, a slide groove may be provided on the first bracket 13, and the second bracket 14 may be slidably disposed in the slide groove. Alternatively, the second bracket 14 may be liftably connected to the first bracket 13 through other intermediate structural members, which is not limited in this specification.

[0066] join Figure 1 and Figure 2 As shown, in some optional embodiments, the display screen 20 is rotatably disposed on the second bracket 14, and the rotation axis of the display screen 20 (such as Figure 2The second bracket 14 is perpendicular to the extension direction of the second bracket 14. In this way, the display screen 20 can be rotated relative to the second bracket 14 to switch between the horizontal screen and the vertical screen to meet the different viewing needs of users.

[0067] In some optional embodiments, such as Figures 3 to 5 As shown, the third sound emitting units 33 are multiple and are distributed around the display screen 20, such as at the four corners or four sides. Alternatively, the third sound emitting units 33 are multiple and are distributed on two opposite sides of the display screen 20 along the length direction or on two opposite sides of the display screen 20 along the width direction. Both of the above arrangements can enable the display screen to achieve stereo sound effects in both the horizontal and vertical screen states.

[0068] Or, if Figure 6 As shown, the third sound-emitting units 33 are multiple and are distributed on opposite sides of the display screen 20 along the length direction and opposite sides of the display screen 20 along the width direction, so that the display screen can achieve more comprehensive stereo sound effects in the horizontal and vertical screen states. In this embodiment, there are eight third sound-emitting units 33, which are distributed on opposite sides of the display screen 20 along the length direction and opposite sides of the display screen 20 along the width direction. It should be noted that the third sound-emitting units 33 can be set according to actual needs, and this specification does not limit this.

[0069] It should be noted that in some other embodiments, the first sound unit 31 and the second sound unit 32 may be provided selectively, that is, only the first sound unit 31 may be provided without the second sound unit 32, or only the second sound unit 32 may be provided without the first sound unit 31.

[0070] For example, see Figure 7 As shown, the multiple sound units 30 may include at least one first sound unit 31 and at least one third sound unit 33, and the audio emitted by the first sound unit 31 is smaller than the audio emitted by the third sound unit 33. The first sound unit 31 is arranged on the base 11, and the third sound unit is arranged on the display screen 20. In this way, a two-way distributed design is realized, and the sound is emitted around the display screen to ensure the mid- and high-frequency effects. The sound emitted from the lower half of the bracket structure (which can be understood as the base) realizes the acoustic effect design of the subwoofer, thereby achieving a more all-round sound package. It solves the problems of sound and picture separation, unclear mid-frequency vocals, and dark timbre, while the bass provides a strong and shocking low-frequency effect. Among them, the number and arrangement of the third sound unit 33 can be the same as Figure 3 or Figure 6 The embodiments shown are identical.

[0071] Alternatively, see Figure 8As shown, the multiple sound units 30 may include at least one second sound unit 32 and at least one third sound unit 33, and the audio emitted by the second sound unit 32 is smaller than the audio emitted by the third sound unit 33. The second sound unit 32 is arranged on the bracket assembly 12, and the third sound unit 33 is arranged on the display screen 20. In this way, a two-way distributed design is realized, and the sound is emitted around the display screen to ensure the mid- and high-frequency effects. The sound is emitted from the top of the bracket structure (which can be understood as the bracket assembly) to achieve the sky sound effect and enhance the mid-frequency hearing. Among them, the number and arrangement of the second sound unit 32 and the third sound unit 33 can be the same as Figures 3 to 6 The embodiments shown are identical.

[0072] In some optional embodiments, the acoustic device 100 may further include a hinge assembly, which is disposed on the support structure 10, and the display screen 20 is rotatably disposed on the hinge assembly, so that the display screen 20 can rotate relative to the support structure 10 to achieve switching between horizontal and vertical screens to meet different viewing needs of users.

[0073] Among them, Fig. 9 As shown, the shaft assembly may include a support 41 and a shaft 42, wherein the support 41 is disposed on the support structure 10, the shaft 42 is rotatably connected to the support 41, and the display screen 20 is connected to the shaft 42, so that the display screen 20 can rotate relative to the support structure 10. Optionally, the support 41 is disposed on the second support 14 of the support structure 10.

[0074] Or, if Fig.10 As shown, the shaft assembly may include a shaft 42, the shaft 42 is connected to the support structure 10, and the display screen 20 is rotatably connected to the shaft 42. The display screen 20 can rotate relative to the support structure 10. Optionally, the support 41 is provided on the second support 14 of the support structure 10.

[0075] Or, if Fig.11 As shown, the hinge assembly may include a first seat body 43 and a second seat body (not shown) rotatably connected to the first seat body 43, the first seat body 43 is arranged on the support structure 10, and the display screen 20 is connected to the second seat body, so that the display screen 20 can rotate relative to the support structure 10.

[0076] It should be noted that the hinge assembly may also adopt other structural forms as long as it can realize the rotation of the display screen relative to the support structure, and this specification does not limit this.

[0077] See also Fig.12As shown, the acoustic equipment in this manual is based on a distributed acoustic architecture system design, which is upgraded from point acoustic design to surface acoustic design, producing a sound experience that is better than other mobile screen products, and better solving the poor visual experience of sound and picture separation of existing market products. In addition, the sky sound solution behind the screen is used to integrate the left and right channels of the large screen to achieve the brightness of the mid-high frequency and the effect of placing the human voice in front of the screen, which not only maintains the full-frequency loudness, but also makes the mid-high frequency more delicate and extended, and the timbre is sweeter.

[0078] Compared with the mobile screen products in the existing market, the acoustic objective frequency response is flatter and the performance is better. It has the following beneficial effects:

[0079] 1) The left and right tweeters of the large screen are used in stereo and the bracket sky sound design to improve the valley caused by the screen blocking the 300Hz-3000kHz. At the same time, the left and right tweeters can improve the high-frequency extension after 6kHz, which can reach 18kHz.

[0080] 2) Separate bass design can directly enhance low-frequency performance, improve low-frequency dive by 10Hz, and increase loudness by about 6dBSPL or more.

[0081] 3) The overall loudness of the whole machine is more than doubled relative to the loudness.

[0082] 4) The distributed design implements the surface acoustic design method, which solves the problem of the screen and sound reaching the human ear at the same level, bringing a better sound quality experience.

[0083] The above description is only a preferred embodiment of this specification and is not intended to limit this specification. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this specification should be included in the scope of protection of this specification.
