Abstract

Disclosed is a low-noise, shock-absorbing speaker cabinet, which includes a cabinet body, a face panel fixedly provided at the front side of the cabinet body for holding a speaker in a hole thereof, a line of first floor bearing portion formed on the bottom side of the face panel and a line of second floor bearing portion formed on the rear end of the bottom side of the cabinet body for supporting the speaker cabinet on the floor, and a suspension open space defined between the front bottom side of the cabinet body and the face panel to reduce floor contact area of the speaker cabinet so as to effectively eliminate noises and shocks and improve the output quality of the speaker.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates speaker systems and more specifically, to a speaker cabinet, which effectively reduces resonant noises and shocks, thereby improving the output quality of the speaker.
2. Description of the Related Art
Music is animal activity which involves structured and audible sounds, which is used for artistic or aesthetic, entertainment, or ceremonial purposes. Listening music is the best simple way to release pressure. Following fast development of technology, CD stereo systems have been intensively used in every family to substitute for conventional big-sized transistor radios. Nowadays, people are more critical on sound quality. Except the factor of the quality of the speaker, the quality of the cabinet is also an important factor that determines the sound quality of the speaker system.
Speaker cabinets vary in price. A pair of simple speaker cabinets may value only few ten US dollars. However, a high quality speaker cabinet may cost more than one thousand US dollar. The quality of a speaker cabinet has a great concern with the measure of eliminating resonant noises during output of sound. A high quality speaker cabinet has means to eliminate shocks and to absorb/isolate sounds, thereby achieving perfect reproduction of original sound.
Speaker cabinet manufacturers are trying hard to keep creating new quality products. Taiwan Patent Publication No. M263706 discloses a shock-absorbing foot member for speaker cabinet. According to this design, the shock-absorbing foot member comprises a stem and footpad. The stem has a threaded body and a conical tip at one end of the threaded body. The threaded body is mounted with a block, a cushion, and nuts. The footpad has a top center hole for receiving the conical tip of the stem. Further, the conical tip of the stem is mounted with a shock-absorbing cap. The shock-absorbing cap has a center through hole fort the passing of the threaded body of the stem. The top center hole of the footpad fits the contour of the shock-absorbing cap so that the shock-absorbing cap with the stem can be tightly secured to the footpad. During operation of the speaker, the shock-absorbing cap absorbs shocks. This design of foot member allows the user to shift the position of the speaker cabinet.
Further, FIG. 1 illustrates a speaker cabinet constructed according to the prior art. According to this design, elastic footpads are directly adhered and fastened to the bottom wall of the speaker cabinet at different locations. When the speaker cabinet is placed on the floor, the footpads support the speaker cabinet above the floor. These footpads can absorb shocks in vertical direction. However, they cannot eliminate resonant vibration during sound output performance of the speaker. Because this design of speaker cabinet cannot eliminate resonant vibration, the speaker cannot achieve the best performance.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a speaker cabinet, which effectively reduces resonant noises and shocks, thereby improving the output quality of the speaker. To achieve this and other objects of the present invention, the speaker cabinet comprises a cabinet body and a face panel fixedly provided at the front side of the cabinet body for holding a speaker in a hole thereof. The cabinet body has a cross section smaller than the face panel. The speaker cabinet further has a line of first floor bearing portion formed on the bottom side of the face panel and a line of second floor bearing portion formed on the rear end of the bottom side of the cabinet body for supporting the speaker cabinet on the floor, and a suspension open space defined between the front bottom side of the cabinet body and the face panel to reduce floor contact area of the speaker cabinet. Because the speaker cabinet is kept in contact with the floor through the line of first floor bearing portion and the line of second floor bearing portion, the speaker cabinet effectively eliminates noises and shocks and greatly improves the output quality of the speaker.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 2˜7, a low-noise, shock-absorbing speaker cabinet in accordance with the present invention is shown comprised of a face panel 1 and a cabinet body 2. The face panel 1 is provided at the front side of the cabinet body 1, having at least one speaker 4 in at least one speaker hole thereof. The cabinet body 2 is fixedly connected to the back side of the face panel 1, having a cross section smaller than the face panel 1.
The speaker cabinet further has a first floor bearing portion 31 formed on the bottom side of the face panel 1, a second floor bearing portion 32 formed on the rear end of the bottom side of the cabinet body 2, and a suspension open space 33 defined between the face panel 1 and the front end of the bottom side of the cabinet body 2.
Referring to FIGS. 2 and 3 again, when the speaker cabinet is placed on the floor, the first floor bearing portion 31 and the second floor bearing portion 32 are disposed in contact with the floor. This linear contact between the speaker cabinet and the floor results in excellent shock-absorbing and low-noise effects. Therefore, the design of the present invention effectively improves the output quality of the speaker 4, eliminating the self-shocking drawback of the prior art multiple contact points design during output of sound.
Referring to FIG. 4 again, the face panel 1 can be made having two recessed holes 11 respectively formed on the two opposite lateral sides thereof and two ornamental strips 12 respectively fitted into the recessed holes 11 to enhance the sense of beauty of the speaker cabinet.
Referring to FIGS. 4˜7 again, the face panel 1 can be made in a circular, square or rectangular shape illustrated in the drawings. Alternatively, the face panel 1 can be shaped like a star or flower. The cabinet body 2 can be made in the shape of a cylinder, cube, quadratic prism, or triangular prism. Alternatively, the cabinet body 2 can be shaped like a star or flower.
A prototype of speaker cabinet has been constructed with the features of FIGS. 2˜7. The speaker cabinet functions smoothly to provide all of the features discussed earlier.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
