  • Patent number: 7510047
    Abstract: A complex speaker edge and asymmetric resonator panel in which the acoustic vibration damping capacity of the speaker edge varies longitudinally around the speaker edge. The resonator panel has an aspect ratio of approximately 1.3:1 or more, and is composed of top and bottom panels held in spaced apart relationship by a plurality of longitudinally extending ribs extending therebetween. The ribs extend at an angle of from approximately 5 to 35 degrees to the longitudinal axis of the panel. The angle is acoustically matched to the complex speaker edge to improve the accuracy with which said acoustic vibration is reproduced. The effectiveness of the differential damping capacity of the edge in improving the quality of sound output from a speaker assembly is determined by observing the average magnitude of the excursions of the sound level pressure versus frequency curves for comparable complex and single speaker edges, particularly in the 200 to 10,000 Hertz range.

The shape employed in the suspension element allows the suspension element to stretch more easily, creating a higher performance speaker of the same size by increasing the diaphragm excursion and voice coil movement.

  • Patent number: 7319774
    Abstract: A speaker includes: a speaker unit; a baffle fitted with the speaker unit; a cabinet fixed to the baffle, the cabinet covering a back of the speaker unit; a plurality of mounting bosses projected from at least one of the baffle and the cabinet; and a packing having elongated mounting holes, the packing located at an abutting part between the baffle and the cabinet, the packing sealing the abutting part. The abutting part includes a plurality of similar sealing areas, which are substantially common in size and shape as a whole except that at least one projecting position of the mounting boss is slightly shifted. The elongated mounting holes of the packing is used for the similar sealing areas. The elongated mounting holes of the packing correspond to the at least one projecting position of the mounting boss and compensate a position shift between the similar sealing areas.

  • Patent number: 7212646
    Abstract: The present invention is a wireless headset having a removable compliant polymer sheath that is retained in the ear of a user via friction. The wireless headset is reduced in size to earpiece, in which the comfort and sanitation of the user and the life span of the device may in increased by providing a replaceable compliant polymer sheath for the sound tube which is inserted into the ear canal. In alternative embodiments, the sheath and ear canal may mechanically cooperate to retain the wireless headset in the ear canal. The sheath may be easily removed and replaced so as to adapt the length and diameter of the device for the needs and comfort of different users, allow safe and sanitary use of one wireless device by more than one user, and allow for easy repairs and refurbishments.

  • Patent number: 7206428
    Abstract: The present invention is a receiver that includes electronics for converting an input audio signal to an output acoustic signal. The receiver has a housing for containing at least a portion of the electronics. The housing includes a port for broadcasting the output acoustic signal. A suspension system is coupled to the housing for dampening vibrations of the housing. In one preferred embodiment, the suspension system includes three resilient contact structures for contacting a surrounding structure in which the receiver is placed. The contact structures are positioned at specific locations to provide variable dampening levels. In another embodiment, the dampening is provided by a low-viscosity, gel-like material positioned between the housing and the surrounding structure.

  • Patent number: 7206422
    Abstract: An assembly (100) for acoustic sealing of a transducer (104) in a communication device is provided. The assembly (100) allows for assembly along one axis (112) and acoustical sealing along another axis (115). The assembly (100) allows for another transducer (106) to be acoustically sealed on a different plane than that of the first transducer (104). Through the use of a compliant member (204) and rigid member (108) coupled to the transducer (104) a floating seal is formed between the chassis (102) and the housing (103) of the communication device (100).
