Abstract

A clamp-to-combine sound collector assembly mainly comprises an upper clamping arm, a lower clamping arm, a sound pickup cup, a weight block, and a spring, the sound pickup cup is disposed at a bottom portion of the front end of the upper clamping arm. The tail end of both the upper and the lower clamping arm are pivotally jointed with each other to form a pivotal joint structure for easy extending or closing the claming arms. The weight block and the spring are hidden in the pivotal joint structure for fixing and ensuring a predetermined included angle and positions of the upper and the lower clamping arm and for further adjustment of clamping tightness of the clamping arms clamped on a mobile phone set.

Claims

1. A clamp-to-combine sound collector assembly, comprising:

an upper clamping arm having a slip receptacle and a fixing piece disposed at a front end and a downwardly extended tail end thereof respectively, wherein a bearing socket is secured to the fixing piece transversely;

a circular shaft receptacle is formed in the bearing socket;

an annular tooth set is aligned on an inner bottom face of the circular shaft receptacle, and, a through hole is also reserved in the circular shaft receptacle;

a lower clamping arm having a tail end extended upwardly to form a fixing piece, which stands oppositely to the fixing piece of the upper clamping arm, wherein a shaft bushing is secured transversely to the fixing piece of the lower clamping arm for being inserted coincidentally in the circular shaft receptacle of the upper clamping arm, and a polygonal store cavity is formed in center of the shaft bushing;

a sound pickup cup, which is substantially a conic hollow body disposed in a slip receptacle of the upper clamping arm, and provided with a pipeline for extending outwardly;

a weight block, which is substantially a polygonal solid body disposed between the store cavity of the lower clamping arm and the circular shaft receptacle of the upper clamping arm, wherein an annular tooth set is formed on a right face of the weight block for engaging with the annular tooth set in the circular shaft of the upper clamping arm, and a protruding part disposed in center of a right end of the weight block penetrates the through hole of the circular shaft receptacle to poke outwardly; and

a spring loaded in the store cavity of the lower clamping arm having one end propped against the weight block for keeping engagement of the annular tooth set of the weight block with the annular tooth set in the circular shaft receptacle under normal conditions;

by abovesaid arrangement, the internal annular tooth sets being detached apart when the protruding part of the weight block is depressed so that the opening and closing angle of the upper and the lower clamping arm can be adjusted easily, or, the relative position of those two clamping arms can be fixed because of the engagement of the annular tooth sets when the protruding part is released.

2. The clamp-to-combine sound collector assembly according to claim 1, wherein a plurality of clamping pieces is disposed along the circumference of the shaft receptacle of the upper clamping arm, and a triangular barb is attached to each tip of the clamping pieces.

3. The clamp-to-combine sound collector assembly according to claim 2, wherein four discrete clamping pieces are equally distributed along the circumference of the shaft receptacle of the upper clamping arm.

4. The clamp-to-combine sound collector assembly according to claim 1, wherein a recessed annular groove is formed in the bottom rim of the shaft bushing of the lower clamping arm for the tip barbs of the clamping pieces to snap at to further keep the relative position of the upper and the lower clamping arm.

5. The clamp-to-combine sound collector assembly according to claim 1, wherein the slip receptacle further comprises three portions, from the top to the bottom, namely, a circular snap recess in a largest scale, a neck section, and a conical cavity, wherein the snap recess is shaped correspondingly with a top portion of the sound pickup cup, the neck section is shrinked to prevent the sound pickup cup from escaping, and the conical cavity is tapered upwardly to match the shape of the sound pickup cup and thereby allow the latter to locate at the slip receptacle of the upper clamping arm.

6. The clamp-to-combine sound collector assembly according to claim 1, wherein the cutaway section of the top end of the sound pickup cup resembles character T, and the top end is to be retained at the snap recess of the slip receptacle of the upper clamping arm when assembling.

7. The clamp-to-combine sound collector assembly according to claim 1, wherein a penetrable wire entry is arranged permitting a pipeline of the sound pickup cup to be extended outwardly.

8. The clamp-to-combine sound collector assembly according to claim 1, wherein a bumper, which is made of a soft material, such as sponge or the like, is arranged at the front end of the lower clamping arm.

9. The clamp-to-combine sound collector assembly according to claim 1, wherein the store cavity of the lower clamping arm is a hexagonal recessed body while the weight block is a hexagonal solid body so that the weight block can move in the store cavity transversely without rotation.

10. The clamp-to-combine sound collector assembly according to claim 1, wherein a circular cavity is recessively formed in the left end of the weight block, and when assembling, two ends of the spring prop against the inner bottom face of the store cavity of the lower clamping arm and that of the circular cavity of the weight block respectively.
