Definitions

  • the present invention relates to headphone and more particularly to an improved headphone having several speakers.
  • Dolby effect disclosed by Dolby Company is a most frequently used audio processing format. Further, Dolby effect has evolved from mono sound to Dolby Stereo, Dolby Surround, Dolby Surround Pro Logic, and Dolby Digital. In response, the number of speakers of a stereo is increased in addition to requirements about locations of speakers and others. As a result, an optimum sound may be realized. In the case of Dolby Surround technique a front left, a front right, a rear left, and a rear right speakers are disposed around a stereo so as to form a sound surround effect.
  • signals of surround portion of sound are coded into left and right sound signals. Further, a decoding circuit is enabled to fetch such signals of surround portion of sound as stereo is playing. Hence, the front left, front right, rear left, and rear right speakers can output sound respectively. At the same time, complimentary portions of left and right sound channels may be processed by a predetermined circuit so as to enhance the surround effect and the orientation of sound. Moreover as to Dolby Surround Pro Logic technique, a central speaker is added into a stereo configured to play in a Dolby Surround environment wherein the coded playing of sound may increase the coding of the central portion of sound.
  • Dolby Digital technique is employed to record sound into six channels. Further, a destructive compression is performed to store sound signals in the channels in a digital manner so as to increase sound articulation. And in turn a better orientation and moving effect of sound may be obtained. Furthermore, such technique increases the surround range. In the example of playing a movie, each speaker installed in various locations of a theater may make a sound respectively. As a result, a stereo effect is brought onto viewers. Moreover, in the case of digital AV device, a Digital Theater System (DTS) is employed which is advantageous over Dolby Digital with respect to sound regeneration. Hence, such DTSs have been widely employed in Digital Versatile Discs (DVDs).
  • DTS Digital Theater System
  • signal lines between speakers and the stereo/AV device are required for signal communication. It may be messy. Hence, signal lines may be broken accidentally by person walking in the environment.
  • signal lines are typically extended from computer ports to ground vertically prior to coupling to speakers. The signal lines are subject to break in the narrow space accordingly. Thus improvement exists.
  • It is therefore an object of the present invention to provide a headphone comprising at least three speakers wherein two of the speakers are held to the ears and the other speaker is in contact with parts of the head other than the ears so that sound from speakers is audible by the ears; a signal line having a conductor and a power line both coupled to each speaker so that external signals are sent to the speakers through the conductor and an external electrical power of source is applied to the speakers through the power line respectively; and at least one signal receiver element formed on a headband being connectable to a sound reproducing device for receiving signals.
  • the headphone comprises a signal line 1 and at least three speakers 2 (five are shown in FIG. 1) wherein two speakers 2 are held to the ears and other speakers 2 are in contact with other parts of the head (e.g., the neck and the rear side of the head). Hence, sound from speakers 2 may be heard by the ears.
  • a conductor and a power line are provided in signal line 1 both coupled to each speaker 2.
  • signals from a sound reproducing device i.e., stereo
  • electrical power may be applied to speakers 2 through the power line respectively.
  • plug 3 is formed on the other end of signal line 1 away from speakers.
  • Plug 3 as signal receiver element is connectable to a sound reproducing device for receiving signals.
  • the number and specifications of ports of sound reproducing device may be varied depending on output signals having various sound processing formats.
  • the number and specifications of plugs 3 of sound reproducing device may be varied depending on the number of output ports and specifications required by the sound processing formats.
  • adapters available for adapting to various outputs having sound processing formats wherein one end of adapter is connectable to output end of plug 3 of headphone and the other end is connectable to output port of sound reproducing device.
  • headphones have sound processing formats different from that of sound reproducing devices may emulate the sound processing format of headphone through the adapter. As a result, speakers of headphone may make a sound.
  • plug is capable of receiving radio signals transmitted from transmitter of sound reproducing device (i.e., served as a radio signal receiver).
  • the circuit of plug may then process the received signals prior to sending it to speakers for output.
  • first headband 4 is flexible and comprises a connection member in one side, an adjustment member on the other side slidable in the connection member, and a fastening member so that user may adjust the length of first headband for adapting the heads of users by sliding the adjustment member in the connection member prior to fastening it by the fastening member.
  • there is a central brace Brace is in contact with the head or the neck while wearing headphone.
  • first headband having a plurality of coupled speakers may not fall.
  • a speaker e.g., woofer
  • a speaker may be provided in the brace for bringing a vibration effect while headphone is activated.
  • a plurality of spaced apart speakers 2 are coupled to second headband 5. At least one end speaker 2 is held to the ear and other remained speakers 2 are in contact with other parts of the body.
  • second headband 5 is a flexible arcuate member.
  • speakers 2 not held to the ears may be suitably disposed by arranging second headband 5.
  • sound from speakers 2 not held to the ears are indirectly transmitted to the ears, while speakers 2 held to the ears are directly transmitted to the ears.
  • sound from speakers 2 cannot be heard by the ears simultaneously if output powers of speakers 2 are the same. In other words, sound is distorted.
  • the output powers of speakers 2 not held to the ears are required to adjust to a number of times larger than that of speakers 2 held to the ears in the invention.
  • a power amplification circuit is provided in each of speakers 2 not held to the ears so that the amplification of output power thereof may be realized.
  • an adjustment circuit is provided in each speaker 2 for making a variety of sound effects (e.g., surround, speaker power, bass, etc.) Adjustment circuit is coupled to circuits in each speaker 2 via at least one knob of speaker 2 so that user may adjust knobs to send generated adjustment signals from the adjustment circuit. Circuits in speakers 2 may then process the received signal for making an optimum sound effect. As a result, an optimum surround effect is obtained from the speakers 2.
  • sound effects e.g., surround, speaker power, bass, etc.
  • two speakers 21 e.g., conventional front left and front right speakers
  • headband 4 there is a central brace on headband 4.
  • Another speaker 22 e.g., conventional woofer
  • Still another pair of speakers 23 e.g., conventional rear left and rear right speakers
  • Speakers 22 and 23 are in contact with other parts of the head other than the ears.
