Abstract

A wireless microphone is provided. The wireless microphone includes: a transmitter wirelessly transmitting audio signals converted from sound collected with a microphone unit; and a receiver receiving said audio signals. A clip is provided on one surface of the transmitter in which the microphone unit is attached to the other surface thereof; and the transmitter is capable of being mounted on a plane using the clip.

Claims

1. A wireless microphone comprising:

a transmitter wirelessly transmitting audio signals converted from sounds collected with a microphone unit, the microphone unit being provided inside of an upper portion of said transmitter and attached on an inner surface of said transmitter, an engaging groove being provided on an outer surface of said transmitter; and

a receiver receiving said audio signals, wherein

a clip is detachably attached to said transmitter by engaging with at least one engaging groove, and wherein the transmitter is configured to be attached to a fixing belt using the clip, the fixing belt having a string-shaped member configured to be hooked onto an upper portion of the clip to prevent the clip from being detached.

2. A wireless microphone according to claim 1, wherein

said clip is detachable from said transmitter by disengaging with the at least one engaging groove.

3. A wireless microphone according to claim 1, wherein

the at least one engaging groove comprises at least one stopper portion, and said clip is engaged with the at least one engaging groove by sliding up to the at least one stopper portion.

4. A wireless microphone according to claim 1, wherein

a strap hole is provided at one end of a casing of said transmitter;

and a strap is attached to said strap hole.

9. A wireless microphone according to claim 3, further comprising two engaging projections provided on a surface of the clip, wherein the at least one engaging groove comprises two engaging grooves, the two engaging projections causing the clip to be engaged with the two engaging grooves.

10. A wireless microphone according to claim 9, wherein the at least one stopper portion comprises two stopper portions.

11. A wireless microphone according to claim 1, further comprising a first engaging piece disposed on a rear surface of the transmitter and a second engaging piece disposed on the clip, the first engaging piece including an ascending slope and a first engaging portion, the second engaging piece including a descending slope and a second engaging portion, wherein the descending slope of the second engaging piece is configured to ascend along the ascending slope of the first engaging piece, and wherein the first engaging portion and the second engaging portion are configured to be fixedly engaged with one another.

14. A wireless microphone according to claim 4, wherein the strap hole is provided at the upper portion of the casing of the transmitter, the strap being configured to hang around a neck of a user of the wireless microphone.

15. A wireless microphone according to claim 1, further comprising a wind screen covering the transmitter, the wind screen being configured to reduce noise caused by wind.

17. A wireless microphone according to claim 1, wherein the receiver is attached to a camcorder, the receiver including an antenna positioned in a direction corresponding with a direction of a light axis of the camcorder.

5. An apparatus for fixing a transmitter of a wireless microphone including a transmitter wirelessly transmitting audio signals converted from sounds collected with a microphone unit and a receiver receiving said audio signals, the microphone unit being provided inside of an upper portion of said transmitter and attached on an inner surface of said transmitter, an engaging portion being provided on an outer surface of said transmitter, wherein:

a clip is detachably attached to said transmitter by engaging with the engaging groove and said transmitter is capable of being mounted on a plane using the clip; and

said clip is attached to a clip attached portion of a fixing belt using said clip; and

a string-shaped member configured to be hooked onto an upper portion of the clip to prevent the clip from being detached is provided on the clip attached portion of the fixing belt.

6. An apparatus for fixing a transmitter of a wireless microphone according to claim 5, wherein

said clip attached portion of said fixing belt is a belt-shaped body whose both ends are locked to the fixing belt or a pocket-shaped body in which both ends and an opposite side to a clip inserting side are locked thereto.

7. An apparatus for fixing a transmitter of a wireless microphone according to claim 5, wherein

a belt portion of said fixing belt includes a plurality of hook-and-loop fasteners, and portions between said plurality of hook-and-loop fasteners are at least made of an elastic member.

8. An apparatus for fixing a transmitter of a wireless microphone according to claim 5, wherein

said fixing belt includes:

a buckle fixed at one end, the clip attached portion being fixed next to the buckle;

engaging surfaces forming one side of a plurality of hook-and-loop fasteners fixed next to the clip attached portion; and

an engaging surface forming the other side of said hook-and-loop fasteners fixed at the other end of said fixing belt.

12. An apparatus for fixing a transmitter of a wireless microphone according to claim 6, wherein the clip attached portion of said fixing belt is the belt-shaped body whose both ends are locked to the fixing belt.

13. An apparatus for fixing a transmitter of a wireless microphone according to claim 6, wherein the clip attached portion of said fixing belt is the pocket-shaped body, the pocket shaped body comprising a cloth, wherein both ends and the opposite side to the clip inserting side of the pocket shaped body are sewn to the fixing belt.

16. An apparatus for fixing a transmitter of a wireless microphone according to claim 5, further comprising a wind screen covering the transmitter, the wind screen being configured to reduce noise caused by wind.

18. An apparatus for fixing a transmitter of a wireless microphone according to claim 5, wherein the receiver is attached to a camcorder, the receiver including an antenna positioned in a direction corresponding with a direction of a light axis of the camcorder.
