Description

Technical Field

[0001] This utility model relates to the field of speaker design, and in particular to a horn structure for a non-directional speaker. Background Technology

[0002] In on-site applications, the building structure and installation method are fixed. Traditional symmetrical horn speakers transmit sound waves symmetrically in the direction of the axis. Under fixed installation conditions, sound waves are easily reflected and consumed by the surrounding environment during transmission, and may even cause phase cancellation, resulting in a large loss of energy. This makes the energy utilization rate of the speaker itself low, thereby reducing the clarity, transparency and liveliness of the sound. The atmosphere of the scene is also greatly reduced, which urgently needs to be improved.

[0003] To address this, a novel asymmetric sound reinforcement compression directional horn is disclosed in the prior art (Announcement No.: CN209002192U, Announcement Date: 2019.06.18). The angle between the upper sidewall of the horn's diffusion surface and the horizontal plane is α, and the angle between the lower sidewall of the horn's diffusion surface and the horizontal plane is β, where α is less than β. This reduces environmental energy consumption, minimizes phase cancellation caused by environmental sound reflections, increases direct sound energy in the listener area, and improves sound clarity, transparency, and liveliness.

[0004] However, in existing technologies and the above-mentioned solutions, the structure of the horn is fixed, that is, it is a directional horn. This horn structure cannot achieve the effect of slight sound adjustment. Since its sound output effect is not adjustable, the application scenarios are limited. Different horn structures need to be set according to different application scenarios to achieve different sound amplification effects, which is inconvenient to operate. Therefore, it is necessary to design a non-directional horn structure that can be manually fine-tuned to be applicable to the existing horn structures. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A horn structure for a non-directional speaker includes a horn body and a speaker enclosure, wherein the horn body is fixedly installed in the speaker enclosure;

[0007] The front side of the speaker enclosure is integrally formed with multiple sound outlets, and the horn body is provided with multiple horn bodies, with each horn body correspondingly covering and installing on the front side of the sound outlet.

[0008] The horn body has mounting holes at all four ends, and sliding columns are slidably installed at all four ends of the sound outlet. A bolt hole is formed in the middle of the front end of the sliding column. The horn body is screwed through the mounting holes and screwed into the bolt holes.

[0009] A toggle lever is fixedly installed in the middle of the outer side of the sliding column. Multiple sliding grooves are formed on both the left and right sides of the speaker cabinet, and the toggle lever is installed in the sliding groove with a clearance fit.

[0010] Furthermore: each of the four ends of the sound outlet is formed with a positioning cylinder, and the sliding column is slidably installed in the positioning cylinder. The outer side of the positioning cylinder is formed with a sliding groove, and the actuating rod is fitted into the sliding groove with clearance. The sliding groove is set in the inner side of the sliding groove.

[0011] Furthermore: the inner side of the positioning cylinder is formed with a positioning groove, and the positioning cylinder is formed with a square groove. A U-shaped spring is fixedly installed in the square groove by screws. The end of the U-shaped spring away from the square groove is fitted into the positioning groove with a gap, and the end of the U-shaped spring inserted into the positioning groove presses on the sliding column.

[0012] Furthermore: a rubber block is fixedly installed at one end of the U-shaped spring sheet inserted into the positioning slot, and the U-shaped spring sheet is pressed against the sliding column by the rubber block.

[0013] Furthermore, the inner side of the horn body is formed with multiple reinforcing ribs, which are arranged in a circular array and staggered from each other with respect to the mounting holes.

[0014] Furthermore, the front surface of the horn body is formed with a tapered amplification surface.

[0015] Furthermore: the four ends of the rear side of the horn body are all formed with lifting cylinders, and the screws pass through the mounting holes and lifting cylinders one by one and are installed in the bolt holes with screw cooperation.

[0016] Furthermore: a speaker cover is fixedly installed on the front side of the speaker enclosure, the speaker cover covers multiple horn bodies, and a protective net is fixedly installed on the front side of the speaker cover.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The sliding column slides at four ends within the sound outlet, allowing for fine-tuning of the horn body's four ends. This can be adjusted according to different scenarios, enabling manual control of the speaker's sound output.

[0019] 2. The horn body is locked into the bolt holes of the sliding column by screws passing through the mounting holes at each of the four ends. Since the horn body is made of soft material, the horn body can make a slight change when the sliding column at each of the four ends moves to different positions, so as to achieve slight adjustment of the sound effect.

[0020] 3. The distance between the horn body and the sound hole can be adjusted by sliding the sliding column, making the sound clearer and more transparent, and achieving non-directional sound tuning.

[0034] like Figure 1-5 As shown, the present invention provides a horn structure for a non-directional speaker, comprising a horn body 1 and a speaker enclosure 2, wherein the horn body 1 is fixedly installed in the speaker enclosure 2.

[0035] The front side of the speaker enclosure 2 is integrally formed with multiple sound outlets 3, and the horn body 1 is provided with multiple horn bodies, and the horn bodies 1 are installed one by one on the front side of the sound outlets 3.

[0036] The horn body 1 has mounting holes 4 at all four ends, and sliding posts 5 are slidably installed at all four ends of the sound outlet 3. A bolt hole 6 is formed in the middle of the front end of the sliding post 5. The horn body 1 is screwed through the mounting holes 4 and screwed into the bolt hole 6.

[0037] A toggle lever 7 is fixedly installed in the middle of the outer side of the sliding column 5. Multiple sliding grooves 8 are formed on both the left and right sides of the speaker cabinet 2. The toggle lever 7 is installed in the sliding groove 8 with a gap fit in a corresponding manner.

[0038] The principle is as follows: by utilizing the sliding column 5 to slide at its four ends within the sound outlet 3, the position of the four ends of the horn body 1 can be finely adjusted. This can be adjusted according to different scenarios, allowing manual control of the sound output effect. The horn body 1 is locked into the bolt holes 6 of the sliding column 5 at its four ends by screws passing through the mounting holes 4. Since the horn body 1 is made of soft material, the horn body 1 can produce corresponding slight changes when the sliding column 5 at its four ends moves to different positions, achieving slight adjustment of the sound effect. At the same time, the distance between the horn body 1 and the sound outlet 3 can be adjusted by sliding the sliding column 5, making the sound clearer and more transparent, and achieving non-directional sound tuning.

[0039] Furthermore: each of the four ends of the sound outlet 3 is formed with a positioning cylinder 9, and the sliding column 5 is slidably installed in the positioning cylinder 9. The outer side of the positioning cylinder 9 is formed with a sliding groove 10, and the toggle rod 7 is fitted in the sliding groove 10 with clearance. The sliding groove 10 is set in the inner side of the sliding groove 8. This makes the sliding adjustment of the sliding column 5 more stable. The setting of the toggle rod 7 can facilitate the movement of the sliding column 5, thereby facilitating the adjustment of the installation position of the four ends of the horn body 1 and realizing non-directional sound tuning.

[0040] Furthermore: the inner side of the positioning cylinder 9 is formed with a positioning slot 11, and the positioning cylinder 9 is formed with a square slot 12. A U-shaped spring piece 13 is fixedly installed in the square slot 12 by screws. The end of the U-shaped spring piece 13 away from the square slot 12 is fitted into the positioning slot 11 with a gap, and the end of the U-shaped spring piece 13 inserted into the positioning slot 11 presses on the sliding column 5. After the sliding column 5 is adjusted, the U-shaped spring piece 13 can elastically reset itself, achieving the effect of pressing the sliding column 5 for self-locking, preventing the horn body 1 from automatically shifting, and realizing the self-locking position of the end of the horn body 1.

[0041] Furthermore: A rubber block 14 is fixedly installed at one end of the U-shaped spring 13 inserted into the positioning slot 11, and the U-shaped spring 13 is pressed against the sliding column 5 by the rubber block 14; the setting of the rubber block 14 can make the U-shaped spring 13 press against the sliding column 5 more stably, avoid slippage, and ensure that the sliding column 5 will not move on its own.

[0042] Furthermore, the inner side of the horn body 1 is formed with multiple reinforcing ribs 15, which are arranged in a circular array and staggered from each other with respect to the mounting holes 4. This effectively strengthens the horn body 1 and ensures that it can maintain its original amplification effect after multiple slight deformations, thereby ensuring its service life.

[0043] Furthermore, the front surface of the horn body 1 is formed with a conical amplification surface 16, which can achieve a better amplification effect.

[0044] Furthermore: the four ends of the rear side of the horn body 1 are all formed with lifting cylinders 17, and the screws pass through the mounting holes 4 and the lifting cylinders 17 respectively and are installed in the bolt holes 6; the lifting cylinders 17 can be used to abut against the end of the sliding column 5 for installation and fixation, so as to achieve precise locking of the horn body 1.

[0045] Furthermore, a speaker cover 18 is fixedly installed on the front side of the speaker enclosure, which covers multiple horn bodies 1. A protective net 19 is fixedly installed on the front side of the speaker cover 18, which can effectively protect the speaker and ensure its service life.

[0046] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
