Technical Field

[0001] The utility model relates to the fields of audio technology and acoustic engineering, and in particular to a sound amplification cover for audio equipment. Background Art

[0002] Music is a powerful tool for expressing emotions. It can convey various emotions such as joy, sadness, anger, calmness, etc. Music is an important part of social activities. It can promote interpersonal relationships and enhance group cohesion. Music can inspire people and boost morale. It is often used in sports, work and various activities. Listening to music can help relax the body and mind, provide entertainment and enjoyment, and learning music can promote brain development, enhance memory, concentration and creativity. Music plays an important role in our lives, affecting our emotions, thinking and social interactions.

[0003] Playing music in large venues like outdoor venues, gatherings, and stadiums often results in low volume. Some technicians use rough power amplifiers, which can effectively increase the volume but can significantly damage the sound source. The resulting sound is noisy and poor in quality, undermining the aesthetic appeal of the music. Replacing high-quality speakers or using power amplifiers are significant drawbacks and are only adequate for lectures and gatherings. When playing music, some speakers are too low in open spaces, making them inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-6 , the utility model provides a technical solution:

[0028] A sound amplification cover for audio equipment comprises a hollow cylinder 1, a connector 2, and a speaker 3. All of these components are made from solid wood. The hollow cylinder 1 is sleeved onto the outside of the speaker. A rotatable connector 2 is mounted above the hollow cylinder 1, and the speaker 3 is mounted on the connector 2 for easy assembly and disassembly. The hollow cylinder 1 is assembled from four zigzag blocks 4. This device fits over the outside of a sound-producing device such as a speaker. Rotating the connector 2 allows the speaker 3 to rotate in different directions, enhancing the sound intensity toward the opening and achieving amplification. The use of solid wood provides improved sound quality.

[0029] Furthermore, the zigzag blocks 4 are zigzag arc-shaped structures. A first hole 5 is formed below the upper protruding portion of the zigzag blocks 4, and a second hole 6 is formed through the lower protruding portion of the zigzag blocks 4. The first holes 5 of the zigzag blocks 4 align end to end with the second holes 6 of another set of zigzag blocks 4. The four sets of zigzag blocks 4 are combined into a hollow cylinder 1 by having the mortise and tenon columns pass through the second holes 6 and the first holes 5. The mortise and tenon columns between the three sets of zigzag blocks 4 can be inserted into the first holes 5 and connected to the second holes 6. The mortise and tenon columns of the last set of zigzag blocks 4 must enter the second holes 6 and extend into the first holes 5.

[0030] Furthermore, two sets of first hoops 8 are provided on the outside of the hollow cylinder 1, and first hoop grooves 7 are installed in both sets of first hoops 8. The hollow cylinder 1 is composed of four sets of zigzag blocks 4. The first hoops 8 are used to prevent the hollow cylinder 1 from falling apart and have a certain decorative effect.

[0031] Furthermore, an annular groove 9 is formed on the inner side of the hollow cylinder 1 , and a connecting piece 2 is installed in the annular groove 9 .

[0032] Furthermore, the connector 2 includes a left connector 10 and a right connector 11. A second hoop groove 12 is formed on one side of the left connector 10 and the right connector 11. A second hoop 13 is installed in the second hoop groove 12. It is recommended to glue the left connector 10 and the right connector 11.

[0033] Furthermore, a connecting post 14 is provided at the end of the connector 2 facing away from the second hoop groove 12, and a mounting surface 15 is provided at the end of the connector 2 proximal to the second hoop groove 12. A male ring 16 is provided at the bottom of the connecting post 14, corresponding to the annular groove 9. The male ring 16 slides and engages within the annular groove 9. The mounting surface 15 is provided with multiple sets of plug-in ports 17. The connector 2 can rotate relative to the hollow cylinder 1 using the male ring 16, allowing the mounting surface 15 to face various angles, even if the horn 3 is facing different angles.

[0034] Furthermore, the horn 3 is formed as a whole from logs, and a plug-in post 18 corresponding to a plurality of plug-in interfaces 17 is provided on one side of the small opening of the horn 3. The plug-in post 18 is plugged into the plug-in interface 17, and the horn 3 is plugged into the connector 2 via the plug-in post 18. Sound is a fluctuation generated by the vibration of an object. When an object vibrates, it causes the molecules of the surrounding medium to move, thereby forming pressure waves. These pressure waves propagate outward in the form of sound waves. This characteristic of sound causes sound to propagate in all directions. Using a horn-shaped structure can gather sound waves and propagate them in a certain direction, thereby amplifying the sound. According to demand, multiple horns 3 of different sizes, different opening angles, and different wood materials can be produced to achieve different sound quality effects. When in use, the opening of the horn 3 should be facing the user. The shape of the horn 3 can cause the sound to be reflected and collected by the wall of the horn, which can enhance the sound intensity in the direction the opening is facing.

[0035] Working principle: When the device needs to be used, cover the hollow cylinder 1 of the device on a sound-generating device such as a loudspeaker, select a suitable horn 3 and connect it to the hollow cylinder 1 and the connector 2, rotate and adjust the angle so that the opening of the horn 3 faces the user, which can achieve the sound amplification function and has excellent sound quality. Different horns 3 can be replaced to have different timbres according to the materials used to make the horn 3. Different sizes and opening angles can reflect different converged sound waves and are suitable for different music.

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