Wirelessly linking a portable audio device to an external audio system permits the external audio system to generate audible signals that enhance local playback of audio by the portable device. For example, the portable device wirelessly transmits lower frequency components of an audio signal to a subwoofer system for reproduction of bass frequencies extending below the playback capability of the portable device. In this manner, the external audio system provides bass enhancement for the portable audio device. Wireless transmissions between the portable audio device and the external audio system may be, but are not limited to, optical or radio frequency (RF) transmissions. Where RF signaling is used, the wireless link may be based on wireless network links, such as those supported by Bluetooth and 802.11b standards, or based on, for example, dedicated RF interfaces.

An apparatus, system, and method for an entertainment chair provide a high fidelity audio system incorporated in an entertainment chair. The entertainment chair is relatively independent from an acoustical environment in which it is placed, and enables repeatable high fidelity sound with a wide variety of recording types and qualities. The entertainment chair has high transparency and excellent imaging. Mid-range speakers and/or tweeters are placed in or near the armrests, forward of the seat occupant, and are oriented to face inward and upward. In one embodiment the mid-range and/or tweeters also angle rearward. A subwoofer is placed in the backrest and a shaker is placed in the seat bottom. The subwoofer and shaker are separately tunable through a control panel ergonomically placed at a forward end of an arm rest. The control panel includes a universal iPod dock. Other inputs may also be connected to the entertainment chair.

A furniture unit including a compartment that contains and conceals a subwoofer, wherein the compartment has vent openings that allow air and sound to pass freely between the subwoofer compartment and the outside of the furniture unit while concealing the subwoofer from the view of a person sitting within a typical viewing angle of a television that is placed on top of the furniture unit or mounted on the wall above the unit.

A mobile electronic device protective cover consists of hinged front panel and rear panel. The rear panel includes a holder portion adapted for holding a mobile electronic device, for example, tablet PC, two pop-up type flat speaker sleeves receivably fastened to the holder portion at two opposite lateral sides for holding one respective speaker driver, a connection portion bonded to the back wall of the holder portion, a box accommodating therein an acoustic transducer module, a subwoofer and a rechargeable power source, a support portion adapted for supporting the holder portion on the front panel in a standing position, and a folding line connected between the connection portion and the support portion.

In the invention there is being combined the back cavities of two speakers so that one speaker is used as a general speaker and the other one provides a boosting effect to the general speaker. For example, the other speaker can act as a subwoofer to the general speaker. The back cavity of the speaker is extended by a tubular cavity. The tubular cavity can extend to either the front or back panel of the mobile phone, thereby boosting the other speaker located at the respective panel.

Embodiments of the present invention comprise a battery charging jobsite audio unit that is particularly useful at construction and other jobsites are disclosed which provides important desirable features and functionality comprise a housing, at least one charger for charging a removable battery pack, an audio unit that includes a speaker system for providing substantially 360° sound, as well as subwoofer, a cord and plug for connecting the unit to a source of AC power, and circuitry for selectively applying power to the audio unit and the charger. The preferred and alternative embodiments also preferably have a unique protective frame structure that is connected to the housing of the unit.

A narrow-profile balanced subwoofer or similar speaker includes a number of drivers placed side by side in the same lateral plane, with a first set of drivers facing one direction and second set of drivers facing the opposite direction. Their orientation is such that the sum of the forces from the first set of drivers is equal and opposite the sum of the forces from the second set of drivers, thus cancelling, and the sum of the moments from all of the drivers about a center or pivot point substantially equals zero. The speaker may include three or more drivers, symmetrically or asymmetrically spaced. The drivers may be of the same or different sizes, and the audio signal amplitudes may be adjusted to help balance the speaker. Each set of drivers may output sound into separate sound ducts, which may output sound from one or more apertures.

A hexagonal speaker with six edges (sides) and four drivers. A pair of drivers is embedded on adjacent edges and another pair of drivers is embedded on the opposite edges, while two opposing edges in between each pair of drivers do not have a driver. A down-firing subwoofer is located on the bottom of the speaker. The speaker is raised off the ground so that the subwoofer can output sound without touching the ground. An air vent tube is also located on the bottom of the speaker adjacent to the subwoofer.

A system and method for minimizing the complex phase interaction between non-coincident subwoofer and satellite speakers for improved magnitude response control in a cross-over region. An all-pass filter is cascaded with bass-management filters in at least one filter channel, and preferably all-pass filters are cascaded in each satellite speaker channel. Pole angles and magnitudes for the all-pass filters are recursively calculated to minimize phase incoherence. A step of selecting an optimal cross-over frequency may be performed in conjunction with the all-pass filtering, and is preferably used to select an optimal cross-over frequency prior to determining all-pass filter coefficients.

An audio chair includes a plurality of speakers and a sound absorbing material. The audio chair may be designed with an egg-shaped body resting on a pedestal. The egg-shaped body may include a hollow region under the seat. A subwoofer may be mounted in this hollow region, while speakers may be mounted around the sides of the inside of the egg-shaped body. The audio chair may provide 5.1 surround sound, 7.1 surround sound, or standard stereo (2.1) sound in the space within the egg-shaped body with very little sound being delivered outside of the audio chair.

The present disclosure relates to a piece of furniture, particularly an adjustable bed, having a speaker system. The bed includes a base having an outer peripheral edge. At least one speaker is mounted to the base of the piece of furniture, typically to the legs. The at least one speaker is mounted to face outwards from a center portion of the bed. The at least one speaker is mounted inboard of the outer peripheral edge of the base of the bed so as to conceal the speakers from a top view. The speaker system may also be used with various other pieces of furniture such as couches, chairs, tables, etc. A subwoofer may also be mounted to the base of the bed.
