Sandwich speaker cabinet

Abstract

A sandwich speaker cabinet, which has an outer cabinet, an inner cabinet mounted inside the outer cabinet, and a flexible shock-absorbing filler layer sandwiched in between the outer cabinet and the inner cabinet to join the outer cabinet and the inner cabinet and to absorb shocks during operation of the speaker system so as to reduce distortion and vibrating noise created by the resonance of the speaker system. The ultimate purpose of this sandwich speaker cabinet is to reduce the distortion and vibrating noise created by the resonance of the cabinet when the speaker drivers are doing piston motion.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates speaker cabinets and more particularly, to a sandwich speaker cabinet, which effectively absorbs shocks during operation of the speaker system, thereby reducing the distortion and vibrating noise created by the resonance of the cabinet when the speaker drivers are doing piston motion.[0003]2. Description of the Related Art[0004]Following the improvement of people's living standard, stereo system has become one of the requisite electric appliances in every family. Music may be used as a human activity for artistic or aesthetic, entertainment, or ceremonial purposes. Innovative music related products have been continuously created following the progress of the time. For example, Taiwan Utility Model No. 568485, entitled “Combination speaker cabinet having fixed buffer means” is one of the typical exemplars.[0005]Early speaker cabinets are commonly made of wood. A wooden speaker cabinet is hea...

Benefits of technology

[0008]The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a sandwich speaker cabinet, which has a high structural strength. It is another object of the present invention to provide a sandwich speaker cabinet, which effectively absorbs shocks during operation of the speaker system, thereby reducing the distortion and vibrating noise created by the resonance of the cabinet when the speaker drivers are doing piston motion.

[0009]To achieve these and other objects of the present invention, the sandwich speaker cabinet comprises an outer cabinet, an inner cabinet, and a flexible intermediate shock-absorbing filler layer. The outer cabinet is made of a hard material, having an opening at the front side. The inner cabinet is made of a hard material and received inside the outer cabinet, having an opening at the front side corresponding to the opening of the outer cabinet. The flexible intermediate shock-absorbing filler layer is filled in the outer cabinet around the inner cabinet to join the outer cabinet and the inner cabinet. During operation of the speaker system, the flexible intermediate shock-absorbing filler layer absorbs shocks, thereby reducing the distortion and vibrating noise created by the resonance of the cabinet when the speaker drivers are doing piston motion.

Problems solved by technology

The angled contours of conventional wooden speaker cabinets are monotonous and do not show a streamline sense of beauty.

However, due to the limitation of wall thickness, size and shape, it is difficult to accurately control the quality when molding a speaker cabinet with polymer compounds.

Uneven wall thickness or local deformation of the cabinet wall may result in a defective product, affecting the sense of beauty and structural strength.

This design of speaker cabinet is not strong.

During voice output of the speaker system, a resonant noise will be produced, affecting the output quality of the speaker system.
