The length of the shaft can be adjusted to adjust the depth of insertion of the shaft into the ear canal, customizing the tool for an individual user. Medial advancement of the shaft into the ear canal is limited by a base, side extension, or mold coupled to a proximal portion of the shaft or other proximal part of the tool. | 2012-11-22 |
20120294468 | HEARING AID MAGNETIC SENSOR WITH COUNTER WINDINGS - A hearing aid includes a magnetic sensor to sense a sound signal being a magnetic field. The magnetic sensor includes a telecoil to sensor the sound signal and a counter coil to cancel a noise signal resulting from electromagnetic interference. In one embodiment, a driver circuit for the counter coil allows for automatic adjustment of the hearing aid circuit for an interference null. | 2012-11-22 |
20120294469 | COVER FOR HAND-HELD ELECTRONIC DEVICE - A cover for a hand-held device, which has a device body and a speaker, includes a cover body configured for covering a portion the device body and for covering the speaker and a channel for positioning adjacent the device body. The channel is configured to form a sound duct when mounted adjacent the back side of the device body and to be in communication with the speaker when the cover is mounted to the hand-held device for redirecting at least a portion of the sound waves emitted from the speaker to a location remote from the speaker. | 2012-11-22 |
20120294470 | Multifunctional Electronic Light Emitting Removable Grip Sleeve For A Paintbrush - The present invention is a multifunctional electronic light emitting removable grip sleeve for a paintbrush. A paintbrush is to be inserted into an encasement to improve handling and control over the paintbrush. The encasement is ergonomic and smoothly contours to the hand of a painter or user. Within the encasement are two elastic walls that can be tapered to allow the handle of a paintbrush to become lodged as it is inserted. Atop the encasement is a plurality of illuminating sources, preferably LED's, which are used to direct light onto a painted surface. Additionally, a multitude of electronic components can be installed into the present invention in increase productivity and provide convenience for the painter. For example, Bluetooth technology can be implemented into the encasement, similar to cellular phones, along with a radio scanner, a stereo system, and a USB port. Painting is facilitated by using the present invention. | 2012-11-22 |
20120294471 | MULTI-CHANNEL SOUND PRODUCING STRUCTURE FOR HEADPHONES - A sound producing structure for headphones comprises an enclosure composed of a box and a perforated cover for sealing the box, the box defining a compartment for accommodating a low-frequency ceramic speaker therein, the low-frequency ceramic speaker being suspended between two opposing interior surfaces of the box respectively via a spring means, two ceramic speakers respectively mounted to a top interior surface and a bottom interior surface of the box respectively via a mounting means, the two ceramic speakers being slantingly mounted and facing toward the perforated cover. The low-frequency ceramic speaker and the two ceramic speakers can work together to deliver sounds of different frequency bands to produce a multi-channel sound effect. In addition, the sound producing structure can be employed to design a thinner headphone for increasing portability. | 2012-11-22 |
20120294472 | METHOD AND APPARATUS FOR A LOUDSPEAKER ASSEMBLY - The present invention relates to a loudspeaker assembly and a method of assembling a loudspeaker assembly. In one or more embodiments, the invention comprises forming a front baffle comprising a first driver mounting portion, an intermediate portion, and an edge mounting portion. A first driver is installed in the first driver mounting portion proximate to a first driver aperture. A rear baffle is formed from a second material, which, in one or more embodiments, is less stiff than the first material from which the front baffle is formed. The rear baffle comprises a top portion, sidewalls, a recessed mounting portion, and an edge portion. The edge mounting portion of the front baffle is attached to the recessed mounting portion of the rear baffle such that an entirety of said front baffle is recessed within said rear baffle spaced apart from said open bottom portion. | 2012-11-22 |
