Abstract: A hearing aid includes a microphone, an electro-acoustic transducer, and a housing that supports the electro-acoustic transducer such that the housing and the electro-acoustic transducer together define a first acoustic volume and a second acoustic volume. The electro-acoustic transducer is arranged such that a first radiating surface of the transducer radiates acoustic energy into the front acoustic volume and such that a second radiating surface of the transducer radiates acoustic energy into the second acoustic volume. The hearing aid is configured such that the first and second acoustic volumes are acoustically coupled to the microphone when the hearing aid is worn. The housing supports an acoustic element that is acoustically coupled to the microphone and the second acoustic volume and is arranged such that acoustic energy radiated from the acoustic element sums with acoustic energy leaked from the first acoustic volume at the microphone so as to cancel each other.

Abstract: A wearable audio device including first and second transducer modules is provided. The first transducer module may include a first transducer. The first transducer module may further include a first enclosure having a top side defining a first slit and a bottom side defining a second slit. The first enclosure may be configured to guide a first sound pressure through the first slit, and a second sound pressure through the second slit. The second transducer module may include a second transducer. The second transducer module may include a second enclosure having a top side defining a third slit and a bottom side defining a fourth slit. The second enclosure may be configured to guide a third sound pressure through the third slit, and a fourth sound pressure through the fourth slit. The third and fourths slit may be arranged diagonally opposite the first and second slits, respectively.

Abstract: A sound outputting apparatus is provided. The sound outputting apparatus includes: a main body; and a loudspeaker accommodated in the main body. The loudspeaker includes: a vibration member configured to generate sound waves; and a sound guide having a first end connected to the vibration member, a second end having an open structure, a first surface between the first end and the second end, and a plurality of openings formed through the first surface along a longitudinal direction of the sound guide. The plurality of openings increase in size as distance from the vibration member increases.

Abstract: The invention is a heated container for carrying water and which permits water to be heated to a controlled temperature. The heated container has safety features to prevent burns and other damage from exposure to heated surfaces, while enabling one handling tools and working with the water from experiencing discomfort of working with cold water or overly hot water. Similarly a utility organizer and a brush holder are shown to demonstrate that the container may be used as a transport means for carrying tools and as means of keeping said tools at an ambient temperatures while in storage.

Abstract: The present invention is therefore designed provide a handsfree concentrated light beam that is directed at a targeted location. The light source is integrated with a head harness, which also houses a battery pack that is positioned in a such a way that creates a perfectly balanced device. The positioning of the battery pack ensures that the harness may be worn continuously without the risk of self-displacement on account of unbalanced weight. The battery back may be easily and quickly replaced. As an additional benefit, the head harness may be weather protected with a hat adornment that accommodates controls for the harness. The invention provides for weather proofing the harness by wrapping within a warm fabric wrap.

Abstract: A speculum tool that adds a lower strap at a point that does not interfere with the with the movement of the jaws of the speculum. The lower strap provides a low point of attachment for the tool. Until now, equine speculums were tethered by the upper strap, with the tether secured onto an immobile structure, such as a wall of a barn. The rear strap would then be looping behind the ears of the patient and back to the opposite side of the speculum's upper jaw. In this way the upper strap provided an overhead attachment that elevated the animal's head during procedure, while the ear strap provided a lower attachment to keep the speculum from slipping off the head and to keep the upper strap from raising the head of an animal too high. The present invention adds additional low point attachment to an already improved rear strap for additional tethering security and as an additional factor in minimizing the risks of harming eyesight and spinal cords of equine patients.
