Boom microphone

Microphone

An interconnect ring is used in attaching the leadwires to the coil wire ends of a microminiature sensor. The interconnect ring is affixed directly to an outside surface of either the core or the coil wire of the microminiature sensor. At least the two flexible ends of the coil wire are electrically joined to metal pads on the interconnect ring. Thereafter, the microminiature sensor can be handled with minimal risk of breakage, shorting or dislodging of the ends of the coil wire. Two other metal pads on the interconnect ring are left open for subsequent attachment of leadwires which can run the length of the catheter device in which the microminiature sensor is used.

Communication headset

An earset microphone includes an earpiece having a wedge portion wherein the wedge portion is positioned between a back side of the ear and a scalp to secure the earpiece in a selected position. A mounting bracket is positioned within the wedge portion. A boom is secured to the mounting bracket and extends from the earpiece such that the boom positions from below an ear lobe towards a mouth of the speaker. A microphone is positioned at the distal end of the boom proximate the speaker's mouth such that the microphone converts the speaker's voice into an electronic signal. An end of a cable is secured to the mounting bracket such that the cable remains secured to the mounting bracket during use and wherein the cable transfers the signal from the microphone to an external component.

A microphone construction for use in a hearing aid wherein a faceplate separates a switching mechanism from a microphone having first and second acoustic ports. The first and second acoustic ports are placed into acoustic relationships with first and second acoustic opening within the faceplate by first and second acoustic passages, respectively. The switching mechanism is positionable between a first position wherein the first and second acoustic ports are in an acoustically receptive state and a second position wherein either the first or second acoustic port is in an acoustically receptive state and the other acoustic port is in an acoustically unreceptive state.

Miniature microphone housing and switch

A wet-mateable fiber optic connector includes mateable and demateable plug and receptacle parts having opposite end housings. The housings mount inner sleeves which interfit with one another when the connector parts are assembled together. Guide and latch fingers attached to the receptacle part facilitate interfitting of the sleeves together and latching and retaining the connector parts in mated condition. A pair of elongated wand structures mounted at outer ends to the end housings receive and hold end portions of respective optical fibers. The wand structures are mounted at inner ends to centering and sealing members in the respective inner sleeves. When the parts are mated together, one of the centering and sealing members mounts in axially aligned and a butting relation respective inner ends of the wand structures and positions in axially aligned and optically coupled relation the respective ends of the optical fiber end portions extending through the wand structures. Pressure compensating bladders in the respective inner sleeves contain an index matching fluid about inner end portions of the wand structures and inner ends of the optical fibers for equalizing the pressure of the index matching fluid therein with that of a fluid of the environment in which the mated connector will be submerged.
