Description

Technical Field

[0001] The invention relates to the technical field of sound boxes, and in particular to a mid-high frequency integrated common-mouth horn. Background Art

[0002] In existing linear array speakers, there are generally two ways to set up the mid-range speaker. The first setting method is to set the mid-range speaker behind the tweeter; the second setting method is to set the mid-range speaker on both sides of the tweeter; for example, a patent document with application number 202022582707.1 in China and announcement date 2021.8.20 discloses a linear array speaker structure, which includes a box body, two inclined walls are arranged at the front of the box body, a tweeter horn is arranged between the two inclined walls, a mid-range unit and a woofer are arranged on the inclined wall, and a diffusion plate is provided on the mid-range unit.

[0003] This speaker structure is provided with midrange units on both sides of the tweeter horn. The midrange unit transmits sound waves outward through a diffusion plate, and the tweeter horn transmits sound waves outward alone. In this way, the midrange unit and the tweeter horn transmit sound waves outward through different outlets respectively, and interference is likely to occur between the midrange and the tweeter. At the same time, the two midrange units transmit sound waves outward through different diffusion plates respectively. The center distance between the two midrange units is long, which will cause interference. The high-end cutoff frequency of the midrange is limited, so the midrange cannot be normally connected with the tweeter. At the same time, the sound source positions of the two midrange units are inconsistent, and mutual interference will occur between the two midrange units. At the same time, a midrange unit, a tweeter horn and another midrange unit transmit sound waves outward independently, and there is no convergence between the three. The directivities of the three sound waves are inconsistent, which leads to low sensitivity of the output sound waves and short propagation distance of the sound waves. Backfield sound filling and delay adjustment are required to achieve long-distance projection of the sound waves. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a mid-range and treble integrated common-mouth horn, in which the mid-range output by the first mid-range horn, the mid-range output by the second mid-range horn, and the treble output by the treble horn are input into the diffusion horn together and then diffused outward, without interference between the sound waves, and the directivity of the output sound waves is consistent, thereby improving the sensitivity of the output sound waves and extending the propagation distance of the sound waves.

[0005] In order to solve the above technical problems, the technical solution used in the present invention is:

[0006] The mid-range and treble integrated common-mouth horn described in the present invention comprises a first mid-range horn, a second mid-range horn, a treble horn and a diffusion horn. The first mid-range horn, the second mid-range horn and the treble horn are all connected to the diffusion horn. The sound waves output by the first mid-range horn, the second mid-range horn and the treble horn are combined by the diffusion horn and then diffused outward.

[0007] Preferably, the treble horn is located between the first alto horn and the second alto horn; the first alto horn and the second alto horn are symmetrically arranged with respect to the treble horn.

[0008] Preferably, the included angle between the first mid-range horn and the treble horn, and the included angle between the second mid-range horn and the treble horn are both θ, and 27°<θ<30°.

[0009] Preferably, the sound wave paths of the first midrange horn and the second midrange horn are consistent.

[0010] Preferably, the first alto horn, the second alto horn and the treble horn are respectively provided with more than two sound wave channels; and the sound wave paths of the more than two sound wave channels are consistent.

[0011] Preferably, the first alto horn includes a first outer wall, a first inner wall, a second outer wall and a second inner wall; the first outer wall and the first inner wall form a sound wave channel, and the second outer wall and the second inner wall form another sound wave channel; the first outer wall and the second outer wall are symmetrically arranged, and the first inner wall and the second inner wall are symmetrically arranged.

[0012] Preferably, the first inner side wall includes a first wall surface and a second wall surface; the second inner side wall includes a third wall surface and a fourth wall surface.

[0013] The first wall and the third wall are arranged close to the input end of the sound wave channel, and the second wall and the fourth wall are arranged close to the output end of the sound wave channel; along the length direction of the sound wave channel, the first outer wall and the second outer wall are arranged to be inclined outward, the first wall and the third wall are arranged to be inclined outward, and the second wall and the fourth wall are arranged to be inclined inward.

[0014] Preferably, the first midrange horn and the second midrange horn are respectively connected to the compression midrange unit; and the treble horn is connected to the compression treble unit.

[0015] Compared with the prior art, the beneficial effects of the mid-high frequency integrated common-mouth horn described in the present invention are mainly reflected in:

[0016] The first midrange horn, the second midrange horn and the treble horn share a diffusion horn; the midrange output by the first midrange horn, the midrange output by the second midrange horn, and the treble output by the treble horn are input into the diffusion horn together and then diffused outward, so that there is no interference between the midrange and the treble; at the same time, there is no interference between the midrange output by the first midrange horn and the midrange output by the second midrange horn. The two midranges merge in the diffusion horn, and there is no distance difference between the midrange output by the first midrange horn and the midrange output by the second midrange horn, which will not affect the high-end cutoff frequency of the midrange.

[0017] At the same time, the sound waves output by the first alto horn, the second alto horn and the tweeter horn are combined by the diffusion horn and then diffused outward, so that the directivity of the sound waves output by the first alto horn, the second alto horn and the tweeter horn is consistent, thereby improving the sensitivity of the output sound waves and extending the propagation distance of the sound waves.

[0018] By arranging the treble horn between the first midrange horn and the second midrange horn, and symmetrically arranging the first midrange horn and the second midrange horn with respect to the treble horn, uniformity is improved.

[0019] The angle θ is set to limit the diffusion angles of the midrange output by the first midrange horn, the midrange output by the second midrange horn, and the treble output by the treble horn in the diffusion horn, thereby improving the directivity of the sound waves after merging.

[0020] The first alto horn and the second alto horn are arranged with the same sound wave path, so that the sound waves emitted by the first alto horn and the second alto horn have the same propagation distance, and then the mid-tone output by the first alto horn and the mid-tone output by the second alto horn can be input into the diffusion horn at the same time. At the same time, the sound wave paths of the first alto horn and the different sound wave channels in the first alto horn are also consistent, so that the distances of the sound waves in different sound wave channels are the same, and then the multiple sound waves output by the first alto horn through different sound wave channels can be input into the diffusion horn at the same time, and the multiple sound waves output by the second alto horn through different sound wave channels can be input into the diffusion horn at the same time; the convergence effect of the sound waves is ensured.

[0021] Through the cooperation of the first outer wall, the first inner wall, the second outer wall and the second inner wall, the sound wave diffuses outward along the inclined surface in the sound wave channel, so that the direction angle of the sound wave in the vertical direction can be controlled. At the same time, the first outer wall is inclined outward, the second wall surface is inclined inward, the second outer wall is inclined outward, and the fourth wall surface is inclined inward, so as to increase the size of the output end of the sound wave channel, improve the sound generation efficiency, reduce distortion and increase the dynamic range; at the same time, the sound wave output from the sound wave channel can be projected and concentrated, the volume can be increased, and the sound wave propagation distance can be further.

[0022] At the same time, a first wall surface and a second wall surface inclined in opposite directions are provided to increase the length of the first inner wall so that the length of the first outer wall is close to that of the first inner wall; while ensuring a large size of the output end, the transmission paths of sound waves on different side walls of the first alto horn are close.

[0023] Compared with the prior art, the present invention describes an integrated mid-range and high-frequency common-mouth horn, in which the mid-range output by the first mid-range horn, the mid-range output by the second mid-range horn, and the high-frequency output by the high-frequency horn are input into the diffusion horn together and then diffused outward. There is no interference between the sound waves, and the directivity of the output sound waves is consistent, thereby improving the sensitivity of the output sound waves and extending the propagation distance of the sound waves. At the same time, by increasing the size of the output end of the sound wave channel, the sound generation efficiency is improved, the distortion is reduced, and the dynamic range is increased; the sound waves output by the sound wave channel are concentrated, thereby further increasing the volume and extending the sound wave propagation distance.

[0032] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used in the present invention are for illustrative purposes only.

[0033] This embodiment provides a mid-high frequency integrated common port horn, such as Figure 1-6 As shown; it includes a first alto horn 1, a second alto horn 2, a treble horn 3 and a diffusion horn 4. The first alto horn 1, the second alto horn 2 and the treble horn 3 are all connected to the diffusion horn 4. The sound waves output by the first alto horn 1, the second alto horn 2 and the treble horn 3 are converged by the diffusion horn 4 and then diffused outward.

[0034] The first midrange horn 1, the second midrange horn 2 and the treble horn 3 share the diffusion horn 4; the midrange output by the first midrange horn 1, the midrange output by the second midrange horn 2 and the treble output by the treble horn 3 are input into the diffusion horn 4 and then diffused outwards, so that there is no interference between the midrange and the treble; at the same time, there is no interference between the midrange output by the first midrange horn 1 and the midrange output by the second midrange horn 2. The two midranges merge in the diffusion horn 4, and there is no distance difference between the midrange output by the first midrange horn 1 and the midrange output by the second midrange horn 2, which will not affect the high-end cutoff frequency of the midrange. At the same time, the sound waves output by the first midrange horn 1, the second midrange horn 2 and the treble horn 3 are merged by the diffusion horn 4 and then diffused outwards, so that the directivity of the sound waves output by the first midrange horn 1, the second midrange horn 2 and the treble horn 3 is consistent, thereby improving the sensitivity of the output sound waves and extending the propagation distance of the sound waves.

[0035] The treble horn 3 is located between the first alto horn 1 and the second alto horn 2; in a preferred embodiment, the first alto horn 1 and the second alto horn 2 are symmetrically arranged about the treble horn 3. By arranging the treble horn 3 between the first alto horn 1 and the second alto horn 2, and symmetrically arranging the first alto horn 1 and the second alto horn 2 about the treble horn 3, uniformity is better.

[0036] In a preferred embodiment, the sound wave paths of the first alto horn 1 and the second alto horn 2 are consistent; the first alto horn 1 and the second alto horn 2 are set with consistent sound wave paths so that the sound wave propagation distances emitted by the first alto horn 1 and the second alto horn 2 are the same, and thus the mid-tones output by the first alto horn 1 and the mid-tones output by the second alto horn 2 can be simultaneously input into the diffusion horn 4.

[0037] In a preferred embodiment, the first alto horn 1, the second alto horn 2 and the treble horn 3 are respectively provided with more than two sound wave channels 5; the sound wave paths of the more than two sound wave channels 5 are consistent. The sound wave paths of different sound wave channels 5 in the first alto horn 1, the second alto horn 2 and the treble horn 3 are also consistent, so that the distances of the sound waves in different sound wave channels 5 are the same, and then the multiple sound waves output by the different sound wave channels 5 of the first alto horn 1, the second alto horn 2 and the treble horn 3 can be simultaneously input into the diffusion horn 4, and the multiple sound waves output by the second alto horn 2 through different sound wave channels 5 can be simultaneously input into the diffusion horn 4; the convergence effect of the sound waves is ensured.

[0038] The first alto horn 1 includes a first outer wall 11, a first inner wall 12, a second outer wall 13 and a second inner wall 14; the first outer wall 11 and the first inner wall 12 form a sound wave channel 5, and the second outer wall 13 and the second inner wall 14 form another sound wave channel 5; the first outer wall 11 and the second outer wall 13 are symmetrically arranged, and the first inner wall 12 and the second inner wall 14 are symmetrically arranged.

[0039] The first inner side wall 12 includes a first wall surface 121 and a second wall surface 122; the second inner side wall 14 includes a third wall surface 141 and a fourth wall surface 142. The first wall surface 121 and the third wall surface 141 are arranged near the input end of the sound wave channel 5, and the second wall surface 122 and the fourth wall surface 142 are arranged near the output end of the sound wave channel 5; along the length direction of the sound wave channel 5, the first outer side wall 11 and the second outer side wall 13 are arranged to be inclined outward, the first wall surface 121 and the third wall surface 141 are arranged to be inclined outward, and the second wall surface 122 and the fourth wall surface 142 are arranged to be inclined inward.

[0040] The sound wave channel 5 of the first alto horn 1, the sound wave channel 5 of the second alto horn 2 and the sound wave channel 5 of the treble horn 3 are of the same shape and will not be described again here.

[0041] Through the cooperation of the first outer wall 11, the first inner wall 12, the second outer wall 13 and the second inner wall 14, the sound wave diffuses outward along the inclined surface in the sound wave channel 5, so that the direction angle of the sound wave in the vertical direction can be controlled. At the same time, the first outer wall 11 is inclined outward, the second wall surface 122 is inclined inward, the second outer wall 13 is inclined outward, and the fourth wall surface 142 is inclined inward, so as to increase the size of the output end of the sound wave channel 5, improve the sound generation efficiency, reduce distortion and increase the dynamic range; at the same time, the sound wave output by the sound wave channel 5 can be projected and concentrated, and the volume can be increased, so that the sound wave propagation distance is longer.

[0042] At the same time, a first wall surface 121 and a second wall surface 122 inclined in opposite directions are provided to increase the length of the first inner wall 12 so as to make the length of the first inner wall 12 close to that of the first outer wall 11; while ensuring a large size of the output end, the transmission paths of the sound waves on different side walls of the first alto horn 1 are made close.

[0043] A third wall 141 and a fourth wall 142 are arranged to be inclined in opposite directions, so as to increase the length of the second inner wall 14 and make the length of the first inner wall 12 and the second outer wall 14 close to each other; while ensuring a large size of the output end, the transmission paths of the sound waves on different side walls of the first alto horn 1 are made close.

[0044] In a preferred embodiment, the size of the diffusion horn 4 gradually increases along its own height direction; the diffusion horn 4 includes a first diffusion arc surface 41, a second diffusion arc surface 42, a first diffusion slope 43 and a second diffusion slope 44; the first diffusion arc surface 41, the second diffusion arc surface 42, the first diffusion slope 43 and the second diffusion slope 44 surround and form the diffusion horn 4. The treble horn 3 is arranged at the bottom of the diffusion horn 4; the first midrange horn 1 is arranged on the first diffusion arc surface 41, and the second midrange horn 2 is arranged on the second diffusion arc surface 42.

[0045] The size of the diffusion horn 4 gradually expands along its own height direction, so that the opening size of the diffusion horn output end is larger than the opening size of the diffusion horn 4 input end; the diffusion horn 4 has a secondary effect on the sound waves output by the first mid-range horn 1, the second mid-range horn 2 and the treble horn 3, further increasing the volume and extending the sound wave propagation distance.

[0046] In a preferred embodiment, the angle between the first midrange horn 1 and the treble horn 3, and the angle between the second midrange horn 2 and the treble horn 3 are both θ, 27°<θ<30°. Specifically, θ is 29°. Setting the angle θ limits the diffusion angle of the midrange output by the first midrange horn 1, the midrange output by the second midrange horn 2, and the treble output by the treble horn 3 in the diffusion horn 4, thereby improving the directivity of the sound waves after merging.

[0047] In a preferred embodiment, two first midrange horns 1 are provided, and each first midrange horn 1 is provided with two sound wave channels 5; two second midrange horns 2 are provided, and each second midrange horn 2 is provided with two sound wave channels 5; six treble horns 3 are provided, and each treble horn 3 is provided with two sound wave channels 5. The first midrange horn 1 and the second midrange horn 2 are respectively connected to the compression midrange unit; the treble horn 3 is connected to the compression treble unit. The compression midrange has low power, high sensitivity, and high maximum sound pressure level. By setting the compression midrange, the sound wave propagation distance can be increased; the output sound wave of the compression treble is large, the sensitivity is high, and the distortion is small. By setting the compression treble, the volume can be increased; by coordinating the compression midrange with the compression treble, the volume can be further increased and the sound wave propagation distance can be extended.

[0048] The mid-range and high-range integrated common-mouth horn provided by the present invention has the mid-range output by the first mid-range horn 1, the mid-range output by the second mid-range horn 2, and the high-range output by the treble horn 3, which are input into the diffusion horn 4 together and then diffused outwards. There is no interference between the sound waves, and the directivity of the output sound waves is consistent, thereby improving the sensitivity of the output sound waves and extending the propagation distance of the sound waves. At the same time, by increasing the size of the output end of the sound wave channel 5, the sound generation efficiency is improved, the distortion is reduced, and the dynamic range is increased. The sound waves output by the sound wave channel 5 are projected and concentrated, further increasing the volume and extending the sound wave propagation distance.
