Non-electronic reverberation speaker

Abstract

To provide a non-electronic reverberation speaker that prevents the degradation of sound quality caused by the amplification of noise contained in a sound source using a non-electronic reverberation speaker that surrounds a conventional sound source with a reverberation board, and that surrounds a reverberation generator with a reverberation board in order to further improve sound quality.SOLUTION: The non-electronic reverberation speaker is composed of a body case 1 with a diaphragm left 2 and a diaphragm right 3 at each end. Multiple springs and coils 4 are supported by the diaphragms 2 and 3. A body case single-side hole 5 is provided on one side of a body of the body case 1. When sound vibrates the body case 1 and the diaphragm left 2 and the diaphragm right 3, the vibration is transmitted to the multiple springs and coils 4. The vibrations that are transmitted to the multiple springs and coils 4 are amplified after resonating and reflecting inside the body case 1, and the vibrations pass through the body case single-side hole 5, producing the effect of reverberant sound. The reverberant sound is diffused and amplified through the reverberation board, cancelling out noise and adding a reverberant effect to the main sound source, improving the sound quality.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a reverberation generator that does not use a power source and achieves a dramatic improvement in sound quality compared to non-electronic reverberation speakers that do not require a power source to diffuse and reverberate sound, and to a non-electronic reverberation speaker that uses the reverberation generator and is surrounded by a soundboard. [Background technology]

[0002] Conventional non-electronic reverberation speakers utilize a mechanism for diffusing and reflecting sound by surrounding the sound source with a sound reflecting board, but they also diffuse and reflect noise contained in the sound source in addition to the sound source. Summary of the Invention [Problem to be solved by the invention]

[0003] As mentioned above, conventional non-electronic reverberation speakers diffuse and reverberate noise contained in the sound source in addition to the sound source, which has the negative effect of canceling out part of the main sound source and resulting in a decrease in sound quality. In exchange for the diffuse reverberation of the sound source, it impairs the experience of feeling the spatial depth and sound quality of the sound source that should be expressed originally.

[0004] The present invention aims to solve the problems of the conventional configuration, and effectively solves the difficulty of the deterioration of the sound source quality caused by non-electronic reverberation speakers when listening to music outdoors without a power source by using a device that creates reverberation without a power source. In addition, since the present invention is a non-electronic item, it is economical as it does not require the purchase of batteries or an electricity contract, and aims to realize psychological uplifting and satisfaction through sound quality. [Means for solving the problem]

[0005] In order to achieve the above object, the present invention uses multiple springs or coils made of metal wires of different thicknesses (metal wire springs or coils, hereinafter referred to as springs or coils), which are covered in a cylindrical case, with a hole on one side of the body of the device, and is further surrounded by a soundboard that also has a passage for sound. In this invention, the word "plural" is used to exclude the word "singular."

[0006] In other words, it utilizes the phenomenon that resonance occurs when sound is transmitted through springs or coils, and by installing springs and coils of different thicknesses, the range of corresponding resonance sounds is increased, thereby generating a wide range of sound reverberation.

[0007] In addition, by drilling a hole on one side of the device's body, the resonant sound generated inside the cylindrical case is efficiently reverberated and amplified, passes through the hole, and is diffused to the outside as a reverberation sound. This device is called a reverberation generating device.

[0008] The reverberation generated from the main sound source and the reverberation generator tube is both amplified and diffused by the sound reflector surrounding the reverberation generator. Effect of the Invention

[0009] As described above, the present invention makes it possible to economically generate reverberation of a sound source without the need to purchase batteries or sign an electricity contract. The generated reverberation is amplified by the soundboard surrounding the reverberation generator. At the same time, the reverberation cancels out the diffused and amplified noise. This makes the main sound source stand out, and the added reverberation effect makes it possible to feel the spatial depth and improved sound quality of the sound source, providing a non-electronic reverberation speaker that brings about a psychological uplifting and satisfaction as an experience. [Brief description of the drawings]

[0010] [Figure 1] FIG. 1 is a cross-sectional view of a reverberation device according to an embodiment of the present invention. [Diagram 2] A diagram showing the reverberation device of the present invention installed inside an area surrounded by soundboards. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to FIG.

[0012] In Fig. 1, reference numeral 1 denotes a main body case, which has a left diaphragm 2 and a right diaphragm 3. A number of springs and coils 4 are supported by the diaphragms 2 and 3. A one-side hole 5 is provided on one side of the main body case 1.

[0013] The operation of the configuration in Fig. 1 will be explained below. When sound vibrates the main case 1, the left diaphragm 2, and the right diaphragm 3, the vibration is transmitted to multiple springs and coils 4. The vibration transmitted to the multiple springs and coils 4 resonates and reflects inside the main case 1, and is then amplified, passing through a hole 5 on one side of the main case, resulting in the effect of the vibration being heard as reverberation.

[0014] An embodiment incorporating the present invention will now be described with reference to FIG.

[0015] In FIG. 2, 6 denotes a non-electronic reverberation speaker body, and a reverberation device 7 according to the present invention is fixedly installed inside.

[0016] The operation of the configuration in Fig. 2 will be explained below. The reverberation device of the present invention does not require a power source and only generates reverberation, so using it alone does not provide any acoustic effect. Therefore, by surrounding the reverberation device 6 of the present invention with a sound board 7 and amplifying both the reverberation and the main sound source, it is possible to obtain effects of improving sound quality such as canceling noise and adding reverberation.
