Definitions

  • the present invention relates to a speaker pillow and more particular relates to a portable pillow that contains an independent, self-contained electrical power source for powering amplified stereo speakers in the pillow.
  • pillows of the type disclosed in the prior art are limited in their use with modern portable or other audio sources in that the headphone jacks of such sources are specifically designed to reduce the audio output to emit a low volume audio signal so as not to "blow" the small frequency speakers used in the headphones. Accordingly, a prior art speaker pillow used with a modern, compact audio unit (e.g. Sony “Walkman” Radio/Cassette Player) would produce an almost inaudible sound, if any at all.
  • a modern, compact audio unit e.g. Sony "Walkman” Radio/Cassette Player
  • a fully portable speaker pillow which can be used with a variety of audio sources, but which will, at the same time, produce high-quality sound at both extremely high and low volume levels. This allows the user to use the pillow either for privacy listening or as an auxialiary speaker system for group listening.
  • the present invention provides a speaker pillow which is fully portable and is capable of reproducing high-quality stereo sound in a full volume range from a wide variety of external audio sources. This is accomplished by providing within the pillow both a dual channel amplifier to amplify the incoming sound to a pair of stereo speakers and an independent, self-contained electrical power source for powering the amplifier.
  • the present invention is comprised of a foam rubber body which has a pair of spaced acoustical chambers formed therein.
  • a high-­quality stereo speaker is mounted in each of the acoustical chambers and are each connected to a respective channel of a dual channel amplifier which is also mounted in the body.
  • Leads connect the amplifier to an audio input jack and also to an internal electrical power source, e.g. dry cell batteries.
  • the body and all components are encased in a zippered jacket which has an opening to provide easy access to the audio input jack.
  • the jack is adapted to be connected to a variety of external audio sources, e.g. portable or conventional stereos, tape or recorder players, television sets, etc., by a standard, commercially-available patch cord.
  • the input jack can be plugged into the headphone jacks of almost any audio/video equipment since the internally-powered amplifier in the pillow will fully amplify the low level audio frequency emitted by the external source before it is fed to the speakers, thereby producing a full volume range sound, without either low frequency distortion or high volume distortion normally produced by the prior art unpowered, unamplified speakers.
  • the pillow of the present invention can be used by an individual in privacy situations or as an auxialiary speaker system for almost all audio equipment.
  • the present pillow can be used with the present day mini- or micro-audio portable equipment (e.g. Sony "Walkman") at a beach or picnic for high-­quality group listening.
  • mini- or micro-audio portable equipment e.g. Sony "Walkman"
  • the present invention is an advancement over the prior art in that it does not restrict a user to the home or automobile, but gives the user complete freedom due to its capability of functioning with commercially-available portable audio equipment without need for adapters or the like and provides high volume sound when desired.
  • FIG. 1 discloses a cross-sectional view of portable, self-amplified stereo speaker pillow 10 in accordance with the present invention.
  • Pillow 10 is comprised of a body 11 of soft, resilient material, e.g. foam rubber, having two acoustical chambers 12 and 13 formed through the upper surface thereof. Chambers 12 and 13 are each spaced an equi-distance from the middle (dotted line 14) with their respective longitudinal axis being angled upwardly and inwardly towards the middle 14 and with respect to the normal horizontal plane of body 11.
  • dotted line 14 the middle
  • FIG. 1 discloses a cross-sectional view of portable, self-amplified stereo speaker pillow 10 in accordance with the present invention.
  • FIG. 1 discloses a cross-sectional view of portable, self-amplified stereo speaker pillow 10 in accordance with the present invention.
  • Pillow 10 is comprised of a body 11 of soft, resilient material, e.g. foam rubber, having two acoustical chambers 12 and 13 formed through the
  • chambers 12 and 13 are substantially deeper than the speakers and accordingly, each act as acoustical chambers providing excellent acoustics for both the bass and treble ranges of the speakers.
  • the upper surface of body 11 has a preformed contour 15 in the center portion thereof for a purpose discussed below.
  • a high quality stereo speaker 16 and 17 is mounted in each of the chambers 12 and 13, respectively, and respective leads 18 and 19 therefrom pass through passages in body 11 and are connected to a proper channel of a dual channel audio amplifier 20, e.g. printed circuit board, which, in turn, is mounted in a preformed cavity in body 11.
  • the speakers 16 and 17 can be any of many commercially available stereo speakers, e.g. Model T105, distributed by JBL Company.
  • Stereo input jack 22, bass control 23, treble control 24, and on-off swithch 25 are built into the amplifier circuit 20.
  • the amplifier 20 is mounted at one side of the body 11, the input jack 22, and all other controls are accessable through openings in jacket 26.
  • An internal, independent electrical power source 21 is provided in body 11 and is connected to audio amplifier 20 by leads.
  • Power source 21 is preferably one or more commercially-available dry cell batteries, either disposable or as a rechargeable battery pack.
  • the body 11 with speakers 16 and 17, amplifier 20, power source 21 and the connecting leads therefor is enclosed or encased in jacket 26, which is shaped and contoured to receive same.
  • jacket 26 is of one piece construction with an opening access to the internal battery power source 21.
  • Jacket 25 may be comprised of any suitable material, e.g. leather, vinyl, cloth, etc. and may be of waterproof material if the pillow is to be used outdoors or near swimming pools or at the beach.
  • Jacket 26 has a padded upper surface 28, positioned to overlie speakers 16 and 17 without distortion or dampening.
  • jacket 25 has an external, pocket 27 thereon, in which, cassett tapes or the like can be stored.
  • External pocket 31 is for holding and protecting a small external audio source 29, e.g. (Sony "Walkman").
  • an external audio source 29 is plugged into input jack 22 by a standard patch cord 30.
  • audio source 25 is shown as a small portable stereo radio/cassette player but it should be understood that pillow 10 can be used with any audio source having an output jack or audio output cord, e.g. console or portable television sets, tape or record players, VCRs, etc.
  • input jack 22, separate bass control 23, and treble control 24, and on-off switch 25 are exposed from amplifier circuit 20 so that user can have easy access to all operating controls of pillow 10.
  • External audio source 29 will be plugged into input jack 22 by patch cord 30 and external audio source 29 can be placed into external pocker 31.
  • pillow 10 in an upright position can be used as an auxiliary speaker system for group listening.
  • External pocket 27 may be used for holding cassette tapes, etc. Rings or the like are sewn to jacket 26 for fastening adjustable carrying straps, not shown.
  • pillow 10 is a fully portable speaker system which can be used indoors or outdoors with almost any available audio source.
  • the low level audio frequency response from the input jack is adequately amplified so the listener can hear the sound without low frequency distortion or loud volume distortion thereby allowing the pillow 10 to be used at very low volume as well as extremely high volume. This allows a listener to lie on the floor or sit in a chair and listen to the speakers without disturbing those around him or he may boost the sound so that others can clearly hear the sound when desired.
