Technical Field

[0001] The utility model relates to the technical field of electroacoustics, in particular to a sound wave guiding device for improving treble quality. Background Art

[0002] A speaker is a device that can convert audio signals into sound. It is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space, making it easier for users to listen through their ears.

[0003] During the use of existing point source speakers, Figure 5 As shown in the figure, treble sound waves are easy to diverge, resulting in scattered radiation, which makes the treble difficult to concentrate, has weak coverage, and weak sound, thus affecting the treble quality of the point sound source speaker. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a sound wave guiding device for improving the quality of high-frequency sounds, so as to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a sound wave guiding device for improving the quality of treble, comprising a first waveguide plate, a speaker and a sound emitting tube, a sound receiving hole being provided on the outer surface of the first waveguide plate, a second waveguide plate being connected to the back of the first waveguide plate, and a reflection block being connected to the upper part of the outer surface of the second waveguide plate, a reflection strip being connected to the upper part of the back of the second waveguide plate, sound guide holes being provided on both sides of the outer surface of the second waveguide plate, a third waveguide plate being connected to the back of the second waveguide plate, and a sound emitting hole being provided on the back of the third waveguide plate.

[0006] By adopting the above technical solution, based on the characteristic of the short wavelength of high-frequency sound waves, after the speaker unit emits sound, the sound waves are reflected and compressed multiple times by the inner wall of the first waveguide plate, the inner wall of the third waveguide plate, the reflection block and the reflection strip, and the high-frequency sound waves of different frequency bands are bundled and then radiated out through the sound release hole, so as to achieve the purpose of improving the treble quality.

[0007] Furthermore, the reflective block is in a truncated cone shape, and the cross section of the reflective strip is in a triangular shape.

[0008] By adopting the above technical solution, the sound waves emitted by the speaker are reflected to the inner wall of the first waveguide plate by the reflection block, and the sound waves reflected from the inner wall of the third waveguide plate are reflected to the sound emission hole by the reflection strip.

[0009] Furthermore, both sides of the first waveguide plate and the third waveguide plate are sloped.

[0010] By adopting the above technical solution, the sloped inner sides of the first waveguide plate and the third waveguide plate can guide the sound waves reflected by the reflection block to the third waveguide plate, and then guide the sound waves to the reflection strip through the third waveguide plate.

[0011] Furthermore, there are two each of the sound receiving hole, the reflection block, the reflection bar and the sound releasing hole, and eight sound guiding holes.

[0012] By adopting the above technical solution, the sound waves pass through the sound receiving hole into the first waveguide plate, and are reflected and compressed by the reflection block and the inner wall of the first waveguide plate in turn, so that the sound waves pass through the sound guide hole into the third waveguide plate, and then are reflected and compressed again by the inner wall of the third waveguide plate and the reflection strip in turn.

[0013] Furthermore, the loudspeaker is connected to the first waveguide plate, and the sound playback tube is connected to the third waveguide plate.

[0014] By adopting the above technical solution, after the speaker emits sound, the sound waves pass through the sound receiving hole and enter the first waveguide plate. After the sound waves are concentrated, they are radiated out through the sound emitting hole and the sound emitting tube to improve the treble quality.

[0015] Furthermore, first limiting rods are provided on both sides of the first waveguide plate, second limiting rods are provided on both sides of the third waveguide plate, and grooves are provided at one end of the first limiting rod and the second limiting rod.

[0016] By adopting the above technical solution, after the first waveguide plate, the second waveguide plate and the third waveguide plate are produced, the staff will clamp the first waveguide plate and the third waveguide plate to the second waveguide plate. Then the staff will first pass the second limiting rod through the third waveguide plate and tighten it, and then pass the first limiting rod through the first waveguide plate and tighten it, and make the first limiting rod and the second limiting rod connected and fastened to each other. The setting of the groove makes it convenient for the staff to tighten the first limiting rod and the second limiting rod with a hexagonal wrench, thereby completing the limiting operation between the first waveguide plate, the second waveguide plate and the third waveguide plate. The contact area is large, the connection is stable and not easy to loosen, and the first limiting rod and the second limiting rod have no protrusions, so that the surfaces of the first waveguide plate and the third waveguide plate are relatively flat and without protrusions.

[0017] Furthermore, the groove is hexagonal.

[0018] By adopting the above technical solution, the provision of the groove makes it easy for the staff to tighten the first limiting rod and the second limiting rod using a hexagonal wrench.

[0019] Furthermore, the first limiting rod is threadedly connected to the first waveguide plate, and the second limiting rod is threadedly connected to the third waveguide plate.

[0020] By adopting the above technical solution, the first waveguide plate and the third waveguide plate clamp the second waveguide plate. Then the staff first passes the second limit rod through the third waveguide plate and tightens it, and then passes the first limit rod through the first waveguide plate and tightens it to complete the assembly of the first limit rod and the second limit rod.

[0021] Furthermore, the first limiting rod is threadedly connected to the second limiting rod, and both the first limiting rod and the second limiting rod are in contact with the second waveguide plate.

[0022] By adopting the above technical solution, the first limiting rod is threadedly connected to the second limiting rod, thereby holding the second waveguide plate in place to prevent the second waveguide plate from falling off.

[0023] In summary, the present invention has the following beneficial effects:

[0024] The utility model arranges the first waveguide plate, the second waveguide plate, the third waveguide plate, the sound receiving hole, the reflection block, the sound guide hole, the reflection strip and the sound releasing hole. According to the characteristic that the wavelength of high-frequency sound waves is short, after the speaker unit emits sound, the sound waves are reflected and compressed multiple times by the inner wall of the first waveguide plate, the inner wall of the third waveguide plate, the reflection block and the reflection strip, and high-frequency sound waves of different frequency bands are bundled and then radiated out through the sound releasing hole, so as to achieve the purpose of improving the treble quality. The high-frequency sound waves are bundled by reflection and compression, thereby improving the treble quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following describes an embodiment of the present invention based on its overall structure.

[0034] Example 1:

[0035] A sound wave guiding device for improving the quality of high-pitched sound, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, it includes a first waveguide plate 1, a speaker 12 and a sound tube 13. The outer surface of the first waveguide plate 1 is provided with a sound receiving hole 4. The back of the first waveguide plate 1 is connected to the second waveguide plate 2. The upper surface of the second waveguide plate 2 is connected to a reflective block 5. The reflective block 5 is truncated. The upper back of the second waveguide plate 2 is connected to a reflective strip 7. The cross section of the reflective strip 7 is triangular. Both sides of the outer surface of the second waveguide plate 2 are provided with sound guide holes 6. There are eight sound guide holes 6. The back of the second waveguide plate 2 is connected to the third waveguide plate 3. The first waveguide plate 1 and the third waveguide plate 3 have two sides. They are all sloped, and a sound-releasing hole 8 is provided on the back of the third waveguide plate 3. There are two sound-receiving holes 4, two reflection blocks 5, two reflection strips 7 and two sound-releasing holes 8. The sound waves are reflected and compressed by the reflection blocks 5 and the inner wall of the first waveguide plate 1, so that the sound waves pass through the sound-guiding hole 6 and enter the interior of the third waveguide plate 3. Then, the sound waves are reflected and compressed again by the inner wall of the third waveguide plate 3 and the reflection strips 7 in turn. Since the sound waves are reflected and compressed multiple times, high-frequency sound waves of different frequency bands are bundled, and then the sound waves are concentrated and radiated through the sound-releasing hole 8 and the sound tube 13 to improve the treble quality.

[0036] See Figure 5 and Figure 6 In the above embodiment, the speaker 12 is connected to the first waveguide plate 1. After the speaker 12 emits sound, the sound waves pass through the sound receiving hole 4 and enter the first waveguide plate 1; the sound emitting tube 13 is connected to the third waveguide plate 3, and the speaker 12 corresponds to the sound emitting tube 13. The sound waves are concentrated and radiated through the sound emitting hole 8 and the sound emitting tube 13.

[0037] Example 2:

[0038] On the basis of the above embodiment 1, in order to facilitate the assembly of the first waveguide plate 1 , the second waveguide plate 2 and the third waveguide plate 3 , the following settings are adopted.

[0039] See Figure 1 、 Figure 3 and Figure 4In the above embodiment, first limiting rods 9 are provided on both sides of the interior of the first waveguide plate 1, and the first limiting rods 9 are threadedly connected to the first waveguide plate 1. Second limiting rods 10 are provided on both sides of the interior of the third waveguide plate 3, and the second limiting rods 10 are threadedly connected to the third waveguide plate 3. The first limiting rod 9 is threadedly connected to the second limiting rod 10, and the first limiting rod 9 and the second limiting rod 10 are both in contact with the second waveguide plate 2. The second limiting rod 10 is passed through the third waveguide plate 3 and tightened, and then the first limiting rod 9 is passed through the first waveguide plate 1 and tightened, so that the first limiting rod 9 and the second limiting rod 10 are connected and fastened to each other; a groove 11 is provided at one end of the first limiting rod 9 and the second limiting rod 10, and the groove 11 is hexagonal. The setting of the groove 11 facilitates the staff to tighten the first limiting rod 9 and the second limiting rod 10 with a hexagonal wrench.

[0040] The implementation principle of the present utility model is as follows: first, after the production of the first waveguide plate 1, the second waveguide plate 2 and the third waveguide plate 3 is completed, the staff clamps the second waveguide plate 2 with the first waveguide plate 1 and the third waveguide plate 3, and then the staff first passes the second limiting rod 10 through the third waveguide plate 3 and tightens it, and then passes the first limiting rod 9 through the first waveguide plate 1 and tightens it, and the first limiting rod 9 and the second limiting rod 10 are connected and fastened to each other. The provision of the groove 11 makes it convenient for the staff to tighten the first limiting rod 9 and the second limiting rod 10 with a hexagonal wrench, thereby completing the limiting operation between the first waveguide plate 1, the second waveguide plate 2 and the third waveguide plate 3, with a large contact area and a stable connection that is not easy to loosen, and the first limiting rod 9 and the second limiting rod 10 have no protrusions, so that the surfaces of the first waveguide plate 1 and the third waveguide plate 3 are relatively flat and have no protrusions;

[0041] During use, according to the characteristic of the short wavelength of high-frequency sound waves, after the speaker 12 makes a sound, the sound wave passes through the sound receiving hole 4 into the first waveguide plate 1, and is reflected and compressed by the reflection block 5 and the inner wall of the first waveguide plate 1 in turn, so that the sound wave passes through the sound guide hole 6 into the inside of the third waveguide plate 3, and then is reflected and compressed again by the inner wall of the third waveguide plate 3 and the reflection strip 7 in turn. Since the sound wave has been reflected and compressed multiple times, high-frequency sound waves of different frequency bands are bundled, and then the sound waves are concentrated and radiated through the sound emitting hole 8 and the sound emitting tube 13 to improve the treble quality.
