BRIEF SUMMARY
BRIEF DESCRIPTION OF THE INVENTION
Recognizing the need for a device to alter the moisture content of the air in the immediate area of the performer or speaker, we have designed a lightweight and convenient nebulizer or humififier which attaches directly to a microphone by means of an attaching device such as a hook and loop fabric strap. The nebulizer is a small cylindrical shaped device which, because of its shape and light weight, goes almost unnoticed by the performer when attached to the microphone.
Noticeable to the performer is the soothing mist emitted by this device which enhances his or her vocal performance. Precise engineering of this minature humidifier causes pressurized carbon-dioxide (CO.sub.2) to mix with distilled water and create a fog-like mist which is able to soothe the vocal chords. The density and quality of the fog-like mist is adjustable to meet the individual needs and preferences of all performers. This fog-like mist cannot be physically seen by the audience, cannot be detected by the sound system.
The carbon dioxide gas which serves as a nebulizer to the distilled water in this device also propels it outward to form a plume of moist air which is invisible except with strong back-liighting. The gas comes in a cartridge which powers the device from two to four hours depending on the setting of the mist control. The quantity of distilled water equals the carbon dioxide gas supply in that it will last from two to four hours, also depending upon the setting of the mist control. Refilling the water supply and changing the cartridge is a fast and easy procedure.
BRIEF DESCRIPTION OF THE DRAWINGS
This invention can be more clearly understood from the following detailed description and by references to the drawings in which:
FIG. 1 is a perspective view of an entertainer using the invention attached to a microphone;
FIG. 2 is a front and elevational view of the external features of this invention;
FIG. 3 is a longitudinal cross-sectional view of the invention showing the internal workings;
FIG. 4 is an enlarged fragmentary longitudinal sectional view of the emitter portion of this invention;
FIG. 5 is an even greater enlarged fragmentary longitudinal sectional view of the helical coil and absorbent disks forming the emitter portion of this invention;
FIG. 6 is a top view of the absorbent fabric disk used in this invention;
FIG. 7 is an enlarged fragmentary longitudinal sectional view of the valve portion of this invention;
FIG. 8 is an exploded view of the invention; and
FIG. 9 is an enlarged, fragmentary perspective view of the knurled filter of this invention taken from the section labelled 9--9 of FIG. 7.
DETAILED DESCRIPTION OF THE INVENTION
Looking now to the detailed drawings in which in FIG. 1, one sees a perspective view of the nebulizer 10 is attached to the handle 11 of a microphone 12 and in use by an entertainer 14. This figure illustrates the relative size and positioning of the nebulizer 10 on the microphone handle 11. The hand 13 of the entertainer 14 comfortably fits around both the nebulizer 10 and the microphone handle 11.
The exact placement of the nebulizer 10 can vary with the personal preference of the individual performer although generally placement of this device is on the upper surface of the microphone handle 11 with the face cap 15 located slightly below the sensitive portion 16 of the microphone 12. When a cardiod microphone is used, the nebulizer is located as close to the null region at the rear of the microphone as possible. This positioning of the nebulizer 10 contributes to a more effective dispersion of the mist emitted by this device into the facial region 17 of a performer where it is needed.
Referring now to FIG. 2 which illustrates the external features of this device. The major portion of the nebulizer 10 is made up of a main body 20 which houses a distilled water reservoir 21 and various emitting elements all of which are shown in FIG. 3.
Somewhat centrally located on the main body 20 is a reservoir filler cap 22 which provides easy access
