Description

Technical Field

[0001] This utility model belongs to the field of audio technology, and more specifically, relates to a composite horn and an audio system. Background Technology

[0002] Speakers are typically equipped with horns to improve sound radiation efficiency, control the direction of sound propagation, and optimize the listening experience.

[0003] The horn includes a mounting base for connecting to the audio driver head and a horn body in the shape of a trumpet connected to the mounting base. The horn body diffuses the sound, but the sound produced by existing horns is not clear and bright enough, and the timbre is poor. Utility Model Content

[0004] The main purpose of this invention is to provide a composite horn, which adds a diffuser tube to make the sound clearer and brighter, and the tone better.

[0005] According to a first aspect of the present invention, a composite horn is provided, comprising a mounting plate, a horn body, and a diffuser tube.

[0006] The mounting plate is provided with through holes;

[0007] The horn body gradually contracts along the first direction, and the smaller end of the horn body is fixed on the mounting plate and covers the through hole;

[0008] The diffuser tube includes a tapered tube and a straight tube that are sequentially joined together along the first direction. The inner diameter of the tapered tube gradually decreases along the first direction, and the straight tube passes through the through hole.

[0009] The distance from the end of the tapered tube away from the straight tube to the mounting plate is greater than or equal to the distance from the end of the horn body away from the mounting plate to the mounting plate.

[0010] In the aforementioned composite horn, the diffuser tube is made of polyethylene.

[0011] In the aforementioned composite horn, the thickness of the diffuser tube is 0.3–1 mm.

[0012] In the aforementioned composite horn, the inner diameter of the straight tube is 15–100 mm.

[0013] In the aforementioned composite horn, the tapered tube has an annular flange at the end furthest from the straight tube.

[0014] According to a second aspect of the present invention, an audio system is provided, comprising a composite horn as described in the first aspect.

[0015] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0016] In this invention, a diffuser tube is added. The horn body and the mounting plate do not need to be modified. Assembly can be completed simply by inserting the diffuser tube into the through hole of the mounting plate. The cost is low. The diffuser tube is narrower and longer than the horn body, which allows the sound to propagate more clearly and brightly, resulting in a better tone. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0026] Example 1

[0027] Reference Figures 1 to 2As shown, a composite horn includes a mounting plate 1, a horn body 2, and a diffuser tube 3. The mounting plate 1 has a through hole 11. The horn body 2 gradually tapers along a first direction, and the smaller end of the horn body 2 is fixed to the mounting plate 1 and covers the through hole 11. The diffuser tube 3 includes a tapered tube 31 and a straight tube 32 connected sequentially along the first direction. The inner diameter of the tapered tube 31 gradually decreases along the first direction, and the straight tube 32 passes through the through hole 11. The distance from the end of the tapered tube 31 away from the straight tube 32 to the mounting plate 1 is greater than or equal to the distance from the end of the horn body 2 away from the mounting plate 1 to the mounting plate 1.

[0028] The horn body 2 and the mounting plate 1 do not need to be modified. Simply insert the diffuser tube 3 into the through hole 11 of the mounting plate 1 to complete the assembly. The cost is low. The diffuser tube 3 is narrower and longer than the horn body 2, which allows the sound to propagate more clearly and brightly, resulting in better tone. This method of modification is the simplest, requiring only the addition of a diffuser tube 3.

[0029] Preferably, the distance from the end of the tapered tube 31 away from the straight tube 32 to the mounting plate 1 is greater than the distance from the end of the horn body 2 away from the mounting plate 1 to the mounting plate 1.

[0030] In this embodiment, the diffuser tube 3 is made of polyethylene.

[0031] In this embodiment, the thickness of the diffuser tube 3 is 0.3 to 1 mm; preferably, the thickness of the diffuser tube 3 is 0.5 mm.

[0032] In this embodiment, the inner diameter of the straight tube 32 is 15-100mm, and the tapered tube 31 is directly connected to the straight tube 32. Therefore, the minimum inner diameter of the tapered tube 31 is the inner diameter of the straight tube 32. This allows the inner diameter of the tapered tube 31 to gradually decrease along the first direction, which is more conducive to sound transmission. The inner diameter of the straight tube 32 is designed according to the size of the horn. Since the size of the horn body 2 is larger, the through hole 11 needs to be larger, and the inner diameter of the straight tube 32 is also larger.

[0033] In this embodiment, the tapered tube 31 is provided with an annular flange 33 at the end away from the straight tube 32, which facilitates the handling of the diffuser tube 3.

[0034] Example 2

[0035] Reference Figures 3 to 4 As shown, a speaker includes a speaker body 4 and a composite horn as described in Embodiment 1. The horn body 2 is fixed to the speaker body 4. The speaker body 4 is also provided with a protective net 5. The protective net 5 can prevent foreign objects from entering the horn body 2 and the diffuser tube 3, and can also prevent the diffuser tube 3 from detaching from the mounting plate 1.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
