    Abstract: A flat panel speaker has a construction in which an actuator 10 vibrates a panel to radiate sound, the panel being held at a peripheral portion thereof on a frame by gaskets, wherein the gasket provided at a position opposite from a position at which the actuator is placed has a higher hardness than that of the gasket provided at another position. The side on which the gasket having the higher hardness is placed is a substantially fixed end to facilitate vibration of the panel, thereby improving sound quality.

    Abstract: An ultra low frequency transducer or subwoofer for automotive speaker systems with a rectangular or square, concave diaphragm. The square periphery preferably is sized to be substantially coextensive with the front of the speaker housing or cabinet. In this way, air displacement in the subwoofer is maximized for a given size of enclosure, and thus so is the loudness of the speaker. The transducer typically includes a frame or basket with a square front for supporting the periphery of the diaphragm. The preferred diaphragm includes a convex surround with pleated corners. For increased durability, trusses are formed in the diaphragm.

    Abstract: The loudspeaker comprises a cone (2) and a beading (4) attached to the cone (2). The beading (4) is composed of a sprayable plastic layer which is soft in its solid state. The manufacture of the loudspeaker is facilitated by a process in which an open negative mold (16) is used in which the cone (2) is arranged and immobilized. Following this, the plastic is sprayed into the open negative mold (16) and the beading (4) is formed as a soft plastic layer which attaches itself to the cone (2).

    Abstract: A dynamic loudspeaker which operates over a wide band of audio frequencies is disclosed. The speaker includes a speaker cone and voice coil structure of very low mass. A configuration of ribs on the cone and dust cap is important to both high and low frequency performance. The rear suspension for the speaker is a bearing on the voice coil structure. The bearing encircles and slides on the magnetic center pole of the speaker. A method of fabricating the low mass coil structure is disclosed, including forming the bearing surface by heat shrinkage of a low friction tape.

    Abstract: A very small audio speaker is described which has a broad-band electrical-mechanical transducer, a broad-band mechanical-air-transducer, and a special suspension system which combine to produce a substantially flat frequency response over substantially the entire audio range from about 50 Hz to about 18,000 Hz.The broad-band electrical-mechanical transducer has either a voice coil with two axially spaced subsections, or a magnetic field with two axially spaced subsections, with the other being continuous between two effective boundaries. Each subsection of the coil, for example, is generally centered on the boundary of the magnetic flux field so that as one subsection moves into the flux field, the other subsection moves out of the flux field at the same rate, thus maintaining a linear force as the coil reciprocates through a much longer distance than is possible using conventional continuous coil and magnetic structures. The increased travel of the coil enhances low frequency performance while simultaneously preventing distortion of high frequency superimposed on the lows. The split coil achieves the long travel without increasing the weight of the coil or the inductance of the coil so that high frequencies can also be efficiently transformed.Both the high and low frequencies can also be efficiently coupled to the air by a broad-band radiating surface characterized by transmission ribs which transmit the motional energy through the plane of the radiating surface at substantially the velocity of sound in air. A membrane extends between the transmission ribs to couple the energy transmitted radially by the ribs to the air. The coil and radiating surface are guided through the long travel by an anti-friction bearing positioned between the voice coil form and the magnetic center pole of the voice coil which introduces no spring forces to distort or retard the movement of the reciprocating members. Additionally, the bearing permits the tolerance between the coil member and the magnetic structure to be significantly reduced, which permits either an increase in the number of turns in the coil, thus increasing the force for a given diameter coil, or a reduction in the size of the magnet to produce the same force. The outer edge of the radiating surface is connected to a peripheral mounting flange by an edge suspension system which seals the annular space, maintains the cone axially aligned, and also exerts a minimum spring biasing force which returns the coil to the center of the magnetic field in the quiescent state. The edge suspension system includes a plurality of non-creeping spring elements, preferably spring steel to maintain long-term stability which are attached to, and damped by, a flexible rolled edge of graduated stiffness. The mid-sized driver is mounted in an unusually small air suspension enclosure.
