Embodiment Construction

[0020] As required, detailed embodiments are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of subject matter that can be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the inventive subject matter.

[0021] Embodiments disclosed herein include an inverted electromechanical transducer with a second front support ring positioned forward of the diaphragm, wherein the front support ring is attached to both the diaphragm and the front frame of the transducer. The front support ring prevents dust and particles from contacting the voice coil and bobbin in this reverse structure electromechanical transducer...

Abstract

An electrodynamic transducer includes a rear frame defining an open frame interior, and a front frame enclosing the open frame interior and attached to the rear frame, the front frame including a center hub disposed about a central axis of the transducer. A movable diaphragm is positioned within the open frame interior and operably connected to the rear frame. A magnet assembly is disposed forwardof the diaphragm and coupled to the center hub, the magnet assembly defining a magnetic air gap annularly disposed about the central axis. A voice coil is disposed in the magnetic air gap surroundingthe magnet assembly and operably connected to the diaphragm. A first spider is coupled between the voice coil and the rear frame behind the diaphragm, and a second spider coupled between the diaphragm and the front frame and disposed forward of the diaphragm.

Description

technical field [0001] Embodiments relate to an inverse electromechanical transducer, such as a low frequency woofer, with a second front support ring positioned in front of the diaphragm. Background technique [0002] Electrodynamic transducers can be used as components in loudspeakers or speaker systems to convert electrical signals into acoustic signals. In a typical loudspeaker system, the transducer includes a magneto assembly, which includes one or more permanent magnets mounted between the top and rear plates, and a voice coil, which is attached to the former and is movable relative to the motor assembly. axial movement. The bobbin and attached voice coil are inserted into the air gap of the motor assembly such that the voice coil is exposed to the magnetic field created by the motor assembly. The coil former is attached to a diaphragm constructed of a flexible material that responds to vibrational input such that the diaphragm is mechanically related to the voice c...
