    Abstract: A horn speaker system includes a dome-shaped diaphragm, a coil bobbin, a phase equalizer, and a magnetic circuit. The coil bobbin is integral with the dome-shaped diaphragm, and a voice coil is wound on the coil bobbin near a free end thereof. The magnetic circuit coacts with the voice coil for producing forces to actuate the dome-shaped diaphragm. The magnetic circuit includes a cylindrical magnet, a first annular yoke attracted to one end of the cylindrical magnet and having a central opening, a plate cooperating with the first yoke in defining a gap in which the coil bobbin is inserted, and a second yoke attracted to an opposite end of the magnet. The magnet, the first yoke, the first plate, and the second yoke jointly make up a closed magnetic circuit. The phase equalizer serves to keep sounds outputted from the dome-shaped diaphragm in phase. The phase equalizer is mounted on the first yoke and has a plurality of slits defined therein. The magnet, the first yoke, the phase equalizer, and the dome-shaped diaphragm are stacked coaxially with each other.

    Abstract: This invention provides an acoustic vibrational material containing various fibers as the reinforcement material and having the epoxy resin as the matrix resin, wherein the epoxy resin is modified by a polybutadiene base elastomer containing not less than 90 mole percent of 1,2-linked units. The epoxy resin modified with the above polybutadiene elastomer exhibits a maximum value of loss coefficient at the temperature region near the room temperature. This region is much higher than that of the conventional epoxy resin modified with polybutadiene elastomer mainly including 1,4-linked unit. Decrease in elastic modulus of the epoxy resin with increase of temperature is lesser in the epoxy resin of the present invention, whereas larger in the conventional one. Thus compatibility between large internal loss and high elastic modulus is achieved.

    Abstract: A miniaturized electrodynamic sound generator comprises a diaphragm, a permanent magnet with pole pieces, a magnet yoke, and a coil. The yoke is designed such that is constitutes a housing or a cabinet of the sound generator. The permanent magnet and the pole pieces are provided in a recess in the cabinet or the yoke and surrounded by the coil, which is connected to the diaphragm at a peripheral area thereof. The diaphragm is provided above the magnet system of the recess and fastened to the outside of the cabinet. The dynamic response of the sound generator is determined by the magnetic, electrical, mechanical, and acoustic parameters which are used in the design of the sound generator. By varying some of these parameters, the frequency and amplitude of a resonance may be chosen such that the sound generator may reconstruct the natural acoustic transfer function in the range of 2-4 kHz in the human meatus. This makes the sound generator particularly suitable for use in hearing aids.

    Abstract: An improved audio transducer includes a diaphragm having a pair of cylindrically-shaped webs that provide greater bandwidth, reduced distortion and greater horizontal dispersion of sound. The audio output of the transducer is further improved by forming the diaphragm of a polyvinyl fluoride film. Other improvements include the use of damping pads to damp internal sound waves and damping strips on the diaphragm to minimize distortion at the resonant frequency of the transducer. In one alternative embodiment a laminated diaphragm is used to damp resonance in the high-frequency end of the transducer operating range.

    Abstract: A waterproof ground audio speaker apparatus has a speaker housing having a cylindrical sidewall, one open end and a closed end. A hollow cylindrical inner housing has a pair of open ends and is attached to the speaker housing with its walls in a spaced relationship to the walls of the speaker housing to form a passageway between the walls of the inner housing and the walls of the speaker housing. A loud speaker is mounted in the hollow inner housing facing one open end thereof for directing acoustical energy out the open end of the speaker housing and directing the backwave of the speaker through the hollow inner housing and through the passageway between the inner housing and the speaker housing to the open end of the speaker housing. A rigid domed supporting cover extends over the opening of the speaker housing and a filter membrane cover covers the open end of the speaker housing to protect the inside of the speaker enclosure. Annular flanges on either end of the speaker housing helps support the speaker housing in the earth and a special filter membrane made of laminated polyester and a polytetrafluoroethylene (TEFLON) sheet which allows the acoustical energy to pass therethrough while blocking the ingress of fluids and other materials into the speaker housing.
