Desktop Microphone Base

The present invention relates generally to a desktop microphone, and more particularly to a base of the desktop microphone.

As shown in FIG. 1, a desktop microphone of the prior art is provided with a base 1 having a flexible tube 2 fastened therewith for holding a retaining tube 3 to secure a microphone 4. Such a prior art desktop microphone as described above is defective in design in that the flexible tube 2 is vulnerable to fatigue, and that the microphone 4 can not be located precisely at a desired level.

It is therefore the primary objective of the present invention to provide an improved desktop microphone base, which enables a user to adjust the position of the microphone at will.

It is another objective of the present invention to provide an improved desktop microphone base which is simple in construction and can be assembled easily.

In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by a desktop microphone base, which is composed of a base body and a pivoting member. The base body is provided with a receptacle. The pivoting member is provided at one end thereof with a pivoting portion engageable with the receptacle of the base body, and at another end thereof with a neck for holding a microphone.

The foregoing objectives, features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention in conjunction with the accompanying drawings.

FIG. 6 shows a schematic perspective view of the pivoting member of the present invention.

FIG. 7 shows a sectional view of the present invention in combination.

As shown in FIGS. 2-7, a desktop microphone base embodied in the present invention is composed of a base body 20, and a pivoting member 40.

The base body 20 is made integrally of a plastic material and is provided with a flat underside 21 for making contact with a desk top. The base body 20 is progressively thickened towards one end which is provided with a circular protuberance 22 located on the upper side of the base body 20. The circular protuberance 22 has an upper side 221 provided with a receptacle 23 of a columnar construction. The receptacle 23 is provided in the brim thereof with three arcuate slots 223 separated equidistantly. The receptacle 23 is further provided with a plurality of furrows 231 extending downwards from both ends of each of the arcuate slots 223 for a predetermined depth. As a result, the receptacle 23 is provided with three retaining portions 233 which are separated equidistantly. Each retaining portion 233 is provided at the top edge thereof with a flat projection 234. The receptacle 23 has a radius R, which is slightly greater than a radius r of an imaginary circle (c) defined by the flat projections 234, as illustrated in FIG. 3. The receptacle 23 is still further provided in the bottom wall thereof with an arcuate recess 236, and in the periphery of the bottom wall thereof with three mold-releasing grooves 238 corresponding in location to the retaining portions 233.

The pivoting member 40 is provided at one end thereof with a pivoting portion 41 of a spherical construction. The pivoting portion 41 has a radius slightly greater than or equal to the radius R of the receptacle 23 of the base body 20. The pivoting portion 41 has a neck 43 extending obliquely therefrom. The neck 43 is provided at the free end thereof with a holding portion 45 tubular in shape for holding a microphone 50 on a desk top. The wall of the tubular holding portion 45 is split along the direction of a longitudinal axis of the tubular holding portion 45 into two portions between which a lengthwise slit 451 is formed.

In combination, the spherical pivoting portion 41 of the pivoting member 40 is forced into the resilient receptacle 23 of the base body 20 such that the spherical pivoting portion 41 is rested in the arcuate recess 236 of the bottom wall of the receptacle 23, as illustrated in FIG. 7. In view of the fact that the radius of the pivoting portion 41 is greater than or equal to the radius of the receptacle 23, the retaining portions 233 of the receptacle 23 are so squeezed as to accommodate the pivoting portion 41 of the pivoting member 40 when the pivoting portion 41 is forced into the receptacle 23. The pivoting portion 41 is therefore held securely by the retaining portions 233 of the receptacle 23 such that the pivoting portion 41 is effectively prevented from becoming disengaged with the receptacle 23. The position of the microphone 50 can be adjusted as desired by turning the pivoting member 40 until such time when the microphone 50 is located at a desired position. The pivoting member 40 is always retained securely by the retaining portions 233 of the receptacle 23 when the pivoting member 40 is turned.

It must be noted here that the pivoting portion 41 of the pivoting member 40 of the present invention is provided with a plurality of cavities 411 for preventing the deformation of the pivoting portion 41, which is subjected to the thermal stress during the molding process.

On the basis of the above detailed description of the present invention, it is readily apparent that the desktop microphone base of the present invention is simple in construction. In addition, a microphone mounted on the present invention can be located with ease and precision.

The embodiment of the present invention described above is to be deemed in all respects as being merely illustrative and not restrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scopes of the following appended claims.
