Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention will be explained in greater detail based on the drawing. As can be seen:

(2) FIG. 1 shows a schematic view of a prior-art boom microphone,

(3) FIG. 2 shows a schematic view of a first embodiment of a boom microphone according to the present invention,

(4) FIG. 3 shows a second embodiment, and

(5) FIGS. 4 to 8 show more embodiments.

DETAILED DESCRIPTION

(6) As can be seen, FIG. 1 shows the front portion of the boom microphone which overall is designated by 1. On the end of the boom 2, a miniaturized microphone 3 is positioned, and in the area adjacent to, but at a certain distance 4 from, the microphone 3, a center of a circular silicone disk 5 is disposed on the boom 2. Beads of perspiration flowing along the boom 2 are stopped by this disk 5 and are intended to drip off said disk instead of continuing on their path to the microphone 3. Although this occurs frequently, it does not occur always and therefore poses a risk to broadcasts and/or performances, not to mention the risk to the microphone. The thickness of the disk 5, i.e., its extension L (mm) in the direction of an axis of the boom 2 is considerably shorter than its diameter D (mm); L/D is considerably lower than 1.

(7) FIG. 2 shows a drip control device according to the present invention, i.e., a silicone screw 5 which is provided in place of the disk 5. As can be readily seen, the extension of this screw perpendicular to the boom 2, again expressed by the diameter D (mm), in comparison to its longitudinal extension along the boom 2 with a length L (mm), is considerably lower, in other words, L/D is considerably greater than 1.

(8) In the lower end region of the silicon screw 5, which is adjacent to the microphone 3, a bead of perspiration 6 is indicated, which bead, on the silicone screw 5, has grown to a considerable size due to the helical and/or loose screw-like structure of said screw and which, because of its high mass, much more readily tends to drip off instead of continuing to run along the boom into region 4 of the boom. It should be noted that the proportions of the microphone 3 relative to the bead of perspiration 6 accurately reflect the proportions actually encountered with boom microphones 1 which are the subject matter of the present invention.

(9) With respect to the conventional prior-art drip control disks, the extension in the radial direction (best described by the diameter relative to the fictitious axis of the boom 2) is comparable to the dimensions of the diameter D of the drip control device according to the present invention; however, because of the character of the small disk, the extension in length is reduced to nearly zero and significantly shorter than D. This has the effect that only very small droplets are formed which tend to climb over the disk and subsequently continue to run along the boom 2 until they reach the microphone. The physical cause of this phenomenon is that the surface forces are greater than the inertial forces.

(10) The use of a silicone thread or band that is wound around the boom 2 is a very simple and inexpensive variation; it is, of course, also possible to use structures which by nature have, broadly speaking, (essentially) the shape of a hollow cylinder and a radial cut 7 across the entire length and thickness (FIG. 4) and which, through elastic deformation, are pushed in an approximately radial direction onto the boom 2. Such a cut can also have a screw-like design so as to reliably prevent the formation of a longitudinal gap. The outer jacket surface of such a hollow cylinder can have the most varied kind of grooves, nubs, ribs, ridges, wells, dents, indentations and other structural elements of a general type so as to make sure that the device can receive and hold the growing size of the beads of perspiration. A few potential embodiments are shown in FIGS. 3 to 8.

(11) The material to be used can be silicone identical to that of the prior-art drip control disks. It is also possible to use a hydrophilic, or at least a non-hydrophobic material, as the surface material of such a drip control structure, especially in combination with a hydrophobic boom surface, in particular, in the region 4 between the drip control device 5 and the microphone 3, so as to ensure the formation of large, and therefore readily dropping, drops. An absorptive material does not offer any better results since, given the normal accumulation of perspiration, the absorptive capacity is rapidly exhausted and subsequently does nothing to contribute to the performance.
