Disclosed is subject matter that proposes a system and method for a media device to automatically detect the characteristics of an attached speaker. Speakers have many different characteristics, for example, power, impedance, frequency response, etc. With knowledge of the speaker characteristics, audio output can be equalized appropriately, and an amplifier of the media device, for example, can prevent exceeding the maximum power handling capability of the speaker. Described is a device and method for retrieving information about the speaker from a memory that is coupled to the speaker. A media device can read the data from the memory over existing speaker wires. Software and / or hardware in the media device can optimize the output to the attached speaker. Accordingly, the media device can interrogate the speaker directly over speaker wire to obtain the characteristics of the speaker.

An elastic headband device with integrated audio system is disclosed. The device includes a stretchable cloth member sized and shaped for positioning about the head and ears of an individual wearer. The cloth member includes a central cavity throughout with first and second side portions and a rear portion. A pair of audio speaker elements are removably disposed within the central cavity of the cloth member at the first and second side portions thereof. A mechanism is also provided for adjusting the relative position of each audio speaker element within the central cavity at its respective side portion to position each element opposite an ear opening of an individual wearer. A central aperture is positioned at the cloth member rear portion for accessing the central cavity. Finally, a plurality of speaker wires are attached to the audio speaker elements within the cloth member central cavity and exit through the central aperture at the rear portion for connection to an audio generation system.

The present invention relates in general to ear muffs and in particular to an earmuff that are to be used in conjunction with headphones for portable radios, cassette players and the like. The outer surface of the earmuff is a solid shape resembling a standard earmuff while the inner side that faces the ear breaks apart into 2 C-shape donut halves to accommodate the placement of the headphone speaker. This design allows the earmuff to be positioned around the headphone speaker by means of the 2 C-shape donut halves and reconnect together around the headphone speaker in order to stabilize against the headphone and allow space for the headphone band and speaker wire between the connected respective halves of the donut. The earmuff makes use of the unique donut design to accommodate various styles of portable headphones while providing maximum insulation to the ear. The earmuffs are detachable and can be exchanged. The earmuff in this invention can be made of various materials customary to cold weather clothing accessories, such as wool, cotton and the like. The earmuff is designed to encompass and protect the headphone speaker from weather elements as well as being made of materials high in insulating capacity and being of a size to envelop the ear of the wearer as well as the surrounding part of the head as is similar to the coverage and insulation provided by typical earmuffs on the market.

A device for housing an electronic device and which is removably secured to a hat such as a baseball hat. The device includes a front portion and two arm portions, with the electronic device preferably secured to the front portion and a speaker member disposed near the end of each arm portion. Speaker wires running from the speakers to the electronic device can be hidden by disposed the wires within the arm portions. As the device is removable it can be easily and quickly removed from securement to a first hat for use with another hat. No modifications, alterations or adjustments to the hat are required for securing the device from one hat to another.

A multi-element single enclosure loudspeaker system uses all of the available driver elements in a linear array of loudspeaker drivers for purposes of reproducing center channel program material, whether discrete within a multichannel mix (such as Dolby Digital 5.1™) or derived from a 2-channel mixdown via any appropriate means (such as SRS™ or Dolby ProLogic™ algorithms), in a manner that provides optimized intelligibility of dialog, improved overall clarity, natural timbre and dynamics of music or other effects and wide bandwidth for a wide range of seating / viewing locations for (domestic) home theater environments.

An impedance matched connection is provided between a load and a power source that outputs signals within a predetermined frequency range. A coaxial line has a predetermined characteristic impedance, an inner conductor, an outer conductor, and an insulator between the conductors. Each conductor has a first end electrically connectable to output terminals of the power source. A compensation circuit has an adjustable impedance, a first terminal electrically connected to a second end of the inner conductor and to a first terminal of the load, and a second terminal electrically connected to a second end of the outer conductor and to a second terminal of the load. The compensation circuit is adjustable to attain, for a pulse having a rise time / fall time faster than the rise / fall times associated with the predetermined range of frequencies, a combined impedance and load that is substantially equal to the characteristic impedance of the coaxial line.

The invention relates to a lung lobe breath sound monitoring and automatic analyzing device which comprises a breath sound signal collecting system, a power supply management module, a breath sound input module, a filter module, an audio power amplifier, a waveform conversion module, a loudspeaker, a CPU processor, a touch screen and an LCD display, wherein the power supply management module is connected with the input end of the breath sound input module by virtue of a wire; the output end of the breath sound input module is connected with the filter module by virtue of a wire; the output end of the filter module is connected with the input ends of the audio power amplifier and the waveform conversion module by virtue of wires; the output ends of the audio power amplifier and the waveform conversion module are connected with the CPU processor; the CPU processor is connected with the touch screen and the LCD display by virtue of wires; and the audio power amplifier is connected with the loudspeaker by virtue of a wire. The device provided by the invention is of non-invasive measurement. Compared with common stethoscopes, the device can capture weak breath sound changes sensitively and objectively, can be used for precisely and dynamically analyzing the result for lung lobe breath sounds and not only is time-saving and labor-saving, but also can reduce the number of times of radiographic inspection on the chest of the patient.

A combination camera and loudspeaker is described herein. The combination camera and loudspeaker includes a lens for selectively manipulating an image and a loudspeaker assembly disposed proximate the lens for projecting audible sounds. In one embodiment, a transparent piezo-electric aligned with at least a portion of the lens projects audible sound based on electrical signals applied to the piezo-electric diaphragm. In another embodiment, a speaker coil and magnet within the loudspeaker assembly encircles an outer perimeter of the lens, while a transparent diaphragm connected to the speaker coil and aligned with at least a portion of the lens projects audible sound based on the interaction between the speaker coil and magnet. The camera captures an image when light is transmitted through the transparent diaphragm to the camera lens. Further, the combination camera and loudspeaker may include a controller for selectively controlling optical properties of the transparent diaphragm.
