Abstract: A microphone for converting sound into an electrical signal includes a generally cylindrical housing including an inlet for receiving sound, an inner backplate, and an outer backplate. The inner and outer backplates are generally cylindrical and substantially concentric with each other. A cylindrical membrane is disposed between the inner and outer backplates. The membrane divides an interior of said housing into a front volume and a back volume. The front volume is in direct communication with the inlet. The backplates and/or membrane are charged. Electronics are included for detecting movement of the membrane relative to the inner and outer backplates in response to the membrane moving when subjected to the sound. The backplates and membrane may be of a shape that approximates a cylinder, such as those that have a hexagonal or octagonal cross-section.

Abstract: A support for a behind-the-ear hearing aid, including a body and a sound tube that includes at least one pad positioned underneath the behind-the-ear hearing aid, and at least one attachment mechanism that connects the at least one pad to the behind-the-ear hearing aid. This support device can also include a moisture guard that includes a sweat pad located underneath the body of the behind-the-ear hearing aid and also includes a muffler pad located adjacent to the microphone of the hearing aid and is attached to the sound tube of the behind-the-ear hearing aid wherein the at least one attachment mechanism further includes a first attachment mechanism to attach the sweat pad underneath the body of the behind-the-ear hearing aid and a second attachment mechanism to attach the muffler pad to the sound tube and adjacent to the microphone of the behind-the-ear hearing aid. The support and sweat pads can, but are not necessarily, made of foam.

Abstract: A hearing aid comprising a case (1) and a horn (2) connectable to the case. The hearing aid also includes an acoustic input aperture and an acoustic output aperture (4). The horn (2) is rotatably supported in the case (1), and a detachable lid (3) is released by rotating the horn (2) from an operational hearing-aid position into a servicing position. In this manner, the lid (3) is simply removed from and/or inserted into the horn. The lid covers as well as forms the acoustic input aperture.

Abstract: A microphone battery case is disposed in the hand grip of the microphone and is provided with a battery slot for receiving removably a battery mount on which a plurality of batteries are mounted. The battery slot is provided with a slide rail and a spring. The battery case is provided with two elastic clamp pieces, each having a hook. The battery mount is provided with two hanging frames, and a projection. The battery mount is received in the battery slot such that the projection of the battery mount is guided by the slide rail of the battery slot, and that the spring is compressed by the battery mount, and further that the hanging frames of the battery mount are caught by the hooks of the elastic pieces of the battery case.

Abstract: A method for disposing a letter sequence onto the outer surface of a microphone wind shield made from foamed material includes the steps of producing at least one letter sequence element on a carrier; positioning the carrier onto the outer surface of the wind shield body by interposing a heat-activating adhesive; applying thermal energy using radiation, in particular, laser beams, for activating the adhesive; and removing the carrier after cooling and solidification of the adhesive. The letter sequence element thereby remains on the outer surface of the wind shield body.

Abstract: A microphone housing comprises a head screen and a head base for mounting a microphone on one end of a hand grip in conjunction with the head screen. The head base is provided in the outer edge with a plurality of elastic clamp pieces, each having a retaining projection. The head screen is provided in the inner edge with a retaining slot. The microphone is mounted on the head base which is detachably retained in the head screen such that the retaining projections of the elastic clamp pieces of the head base are retained in the retaining slot of the head screen. The head screen is detachably fastened with one end of the hand grip.

Abstract: The present invention relates to a directional microphone, in particular having symmetrical directivity, having an interference tube with a tube axis which is provided with a row of sound inlets arranged at least approximately parallel to tube axis, and which incorporates an electroacoustic transducer in its inside in the vicinity of its rear end face. It is further provided that the row of sound inlets is arranged non-symmetrically to tube axis opposite the outer periphery of interference tube.

Abstract: An acoustic damper for covering a housing inlet of a transducer is disclosed. The damper includes a mesh panel and a non-mesh periphery. The non-mesh periphery of the damper is adhesively attached to the housing of the transducer wherein the mesh panel covers the inlet. The non-mesh periphery of the damper inhibits the adhesive from wicking into the mesh panel. The damper is adaptable for attachment of a film. The film is capable of cooperating with a backplate to form a motor assembly of the transducer.

Abstract: The pressure-difference microphone is arranged in a housing, and there is provided in one of the housing walls a single opening, directed onto the front side of the microphone, for feeding voice commands which can be produced in the acoustic near field of the housing. According to the invention, the arrangement of the microphone and/or the air volume which surrounds the microphone in this case are such that the microphone can be irradiated with sound through the opening, using the pressure-difference principle.

Abstract: A transmitter structure which is resistance to wind noise and the like and allows a reduction in size is disclosed. A sound hole is formed in a case at an offset position with respect to a microphone, and a slit extending from the sound hole to the microphone is filled with an acoustic resistance cloth.

Abstract: The present invention provides a method (600) and device (400) for minimizing wind-induced noise in a microphone. The device includes: a housing (412) having a recessed area shaped to accommodate a microphone transducer (410); the microphone transducer (410), situated within the recessed area such that a thin film situated over the microphone transducer is flush with/overlaying a top of the recessed area and affixed at least to the sides of the recessed area, for receiving sound; and the thin film (402) has at least one aperture (404, . . . 406) for allowing sound to impinge on the microphone transducer (410), and has a minimal thickness that maintains structural integrity.
