International Classification:

H04R 25/00

US Classification:

381340, 381339, 381342

Abstract:

A speaker system including a first and a second horn, each having a respective acoustic driver and a respective planar mouth and a respective throat operationally connected between the respective acoustic driver and the respective mouth, wherein the mouths are substantially coplanar. The system is characterized by an acoustic dispersion angle of about thirty degrees in a first vertical dispersion plane and by an acoustic dispersion angle of at least about ninety degrees in a second horizontal dispersion plane oriented orthogonally to the first dispersion plane.

Abstract:

An improved ear tip for earphones and hearing protection is provided where comfort and occlusion of the ear are of most importance. The ear tip comprises an elastomer polymer resin material molded to form the material to the shape of the ear canal. A chamber is defined having a proximal and distal end, the distal end engages the acoustic exit of the transducer, sound source or sound attenuator and the proximal end of the bore is adapted to be disposed adjacent an eardrum. The inner body attaches to a nozzle, or audio playback orifice to naturally transition the acoustics from the transducer or sound attenuator to the eardrum via the ear canal. The ear tip can have a plurality of flexible annular flanges disposed at spaced intervals of the body with decreasing circumference as the flanges transition to the proximal end. Each flange tapers in a radius or curvilinear geometry as it progresses to the end of the object.

Abstract:

A balanced armature apparatus is disclosed that includes dual transducers for generating sound waves in response to electric audio signals. The dual transducers include a motor assembly coupled to a diaphragm. A housing defines an interior chamber and the motor assembly and the diaphragm are positioned within the interior chamber. A pair of acoustic output ports is located in a respective end of the housing. A low pass acoustic filter is in communication with one of the acoustic output ports that is operable to attenuate a predetermined range of frequencies from an audio signal produced by one of the diaphragms.
