The present invention relates to an improvement of a speaker, and more particularly, to a seismic noise reduction structure of a speaker for enhancing output sound quality, which can effectively reduce resonance by effectively reducing resonance of a speaker box having a good damping effect.

Music is the simplest way to relieve stress in today's busy industrial society because it can cultivate the human mind, soothe mind and body, and cultivate culture. Related products are not broken with the progress of the times, and new ones have been made. For example, large-sized transistor radios have already been replaced by CD sound. As the income of modern homes increases, the demand for music is also relatively high, so that the sound itself is expensive, and the speaker, which is the output device of the device, is also an important factor in determining the good and bad sound quality. .

The difference between good and bad and value of speakers is quite large, and the simplest small speakers can be bought for thousands of dollars in a set, but high-end speakers require hundreds of thousands or even millions of dollars. In fact, whether or not it is high quality is related to whether or not the generation of resonance at the output can be avoided, and the more advanced speaker has good seismic resistance, sound absorption and soundproofing, and this achieves the original sound reproduction at the output, so that the noise by resonance Disappear.

For this reason, the relevant industry has made great efforts to study and improve this, for example, the seismic leg structure of the speaker of the Republic of China Patent Publication No. M263706 is one of its typical representatives, and it is appropriately composed of leg rests, The center of the aldan is formed by the top portion, the other end is formed by the bolt portion. On the bolt, parts such as a fastening frame, a washer, a fastening nut and a fitting nut are again installed. In the center of the surface of the leg rest, there is a center groove into which the popper is inserted. A feature of this feature is that a sensing cloth is provided on the outer periphery of the top, and the sensing cloth is provided with a hole for attaching a bolt to the center of the closed end, and an open end of the sensing cloth is fastened around the surface of the leg support. A concave fitting surface is formed to be attached so that the leg rests are integrally joined together by a dampened sheath. In use, the speaker box achieves both a damping effect and a convenient moving effect at the same time.

By the way, as shown in Fig. 1, in the design of the known speaker box to date, many of them use the intervals distributed in the form of dots by attaching or firmly tightening the elastic footrest to the selected part of the lower part of the speaker box. When sound is output by supporting the speaker box, noise caused by resonance of the speaker box and the contact surface can be avoided. By the way, the design of the elastic footrest at the bottom of this structure achieves the effect of avoiding vibration by adjusting up and down, but in fact, the design of this point-shaped elastic foot can effectively dissolve and eliminate the resonance of the speaker box. The main drawback is that, when the overall speaker box makes a voice, the vibration generated in itself still exists, so that optimum sound quality cannot be achieved at the time of output.

In view of this, the inventor of the present invention was able to conduct the research and design in depth, and after various experiments and improvements, the inventors could finally produce the present invention.

The main object of the present invention is to provide a seismic noise reduction structure of a speaker that can effectively reduce the resonance of a speaker box having a good damping effect to reduce noise and improve the output sound quality.

In order to achieve the above-mentioned object, the main configuration of the seismic noise reduction structure of the portable speaker designed in the present invention is installed in connection with the front part of the speaker box, and provided with a hole for installing and fixing the speaker,

Integrally molded and connected to the rear side of the cabinet, the speaker box being embedded at the rear side of the cabinet because it is smaller than the area of the cabinet,

A first landing portion is provided below the cabinet, a second landing portion is provided at the bottom of the rear end of the speaker box, and a locking portion is formed between the cabinet and the front end of the speaker box. The lower side of the speaker box constituted by this is in contact with the ground by a line formed by the first landing portion of the cabinet and the second landing portion of the speaker box, and the contact area is reduced to produce a good seismic effect, thereby reducing noise. The speaker's output sound quality can be effectively increased.

In order to fully understand the configuration and other features of the subject innovation, specific embodiments of the subject innovation will be described in detail with reference to the drawings as follows.

As shown in Fig. 2 to Fig. 7, the main configuration of the seismic noise reduction structure of the portable speaker designed by the present invention is provided in connection with the front part of the speaker box 2, and the speaker 4 is installed and fixed. Speaker boxes (2) which are integrally molded with the cabinet (1) in which the holes are provided and connected to the rear side of the cabinet (1), are embedded in the rear side of the cabinet because they are smaller than the area of the cabinet (1). ). The first landing part 31 is provided below the cabinet 1, and the second landing part 32 is provided in the bottom end of the speaker box 2, and the cabinet 1 and the speaker box 2 The engaging portion 33 is formed between the front ends of the).

As a result, as shown in Figs. 2 and 3, when the structure constituted as a whole is applied, the lower side contacts the ground by a line formed by the first landing portion 31 and the second landing portion 32, Since the contact area of the speaker box 2 is reduced and a favorable seismic effect is produced, noise is reduced, and the defect that its own vibration is present at the time of outputting the elastic support on the gap point conventionally provided can be greatly improved.

In addition, as shown in Figures 4 to 7, when the present invention is implemented, the concave hole 11 is installed around the rim of both sides of the cabinet 1, the molding decorative plate 12 is installed here Can enhance the sense of beauty. The cabinet 1 may be composed of plates shown in the drawings, such as circles, squares, rectangles, or various plates, such as ovals, triangles, polygons, stars, and petals, which are not shown in the drawings. The speaker box 2 is also composed of the same circular column, elliptical column, rectangular frame, rectangular frame, triangular frame, polygonal frame, star frame and petal frame, and the combination of the two forms a variety of different configurations to diversify the product. Can be increased.

In summary, the design of the present invention is simple in structure, has a good damping effect, can reduce noise by really reducing the resonance of the speaker box, and the function of improving the output sound quality is much higher than that of the conventional one. It is better, because of the progress and the useful value of the industry, the utility model registration is applied according to the law.

The specific embodiments described above are intended to describe in detail the purpose, features, and effects of the present invention, and illustrate some embodiments of the present invention, and are not intended to limit the scope of the present invention thereto, and will be described in detail by those skilled in the art. Unless a simple change or improvement from the structural features and effects described in the description does not depart from the spirit of the present invention, it should all be included in the claims of the present invention.
