Definitions

  • the invention relates to an improved structure of headphones with a multichannel guiding mechanism, and more particularly, to headphones having different channel speakers positioned within each of earphones and separate sound-guiding chambers for receiving the different channel speakers.
  • the separate sound chambers are installed within the earphones according to characteristics of the sound effect of different channel speakers. Accordingly, a clear positioning of the acoustic field is achieved by different installation position of the speakers within the earphones. In addition, the interference of sound waves is avoided and the reproduction of original sound is achieved.
  • DVD players or the surround amplifiers include an analog output terminal of 5.1-ch sound signals for establishing a home theater system with TV, DVD player, surround amplifier and 5.1-ch speaker.
  • Multichannel or 5.1-channel output enables the listeners to enjoy a high quality of sound.
  • the original sound can't be reproduced by the conventional headphones.
  • the sound quality of multichannel or 5.1-channel output must be deteriorated to some extent.
  • the design of the sound chamber must be adapted to the characteristics of the respective channel speaker.
  • the front main channel speaker has to be larger than others.
  • its middle section belongs to the treble area while the periphery of the treble area belongs to the bass area. The inventor of the invention found that the treble and the bass are easily mixed and, thereby resulting in a worse sound quality when the treble and the bass are not properly separated.
  • the sound chambers are designed according to the characteristics of each channel speaker and in taking acoustic principles and transmission structure into account. This allows a clear positioning of the acoustic field.
  • the interference of sound waves is avoided and the reproduction of original sound is achieved.
  • the sound pressure is uniformly dissipated within each separate sound chamber, thereby enlarging the surround sound effect. So, the listener can enjoy high quality multichannel sound effect without electronic combination technique for 5.1-channel simulation.
  • the exit of the separate sound chamber is located at the rear side of the earphone.
  • the sound tube for defining the sound chamber can be extended for delaying the output of the sound waves, thereby resulting in a rear positioning of the sound.
  • a headphone with multichannel guiding mechanism in accordance with a first embodiment of the invention includes a pair of earphones 1 with a headband 2 for holding them on the top of the head. Meanwhile, an electric cord for transmitting multichannel sound signals is connected under the earphones 1.
  • the internal structure of the earphones 1, as shown in FIGS. 2 and 3, includes a main body 10, a cover portion 30 and an ear contact portion 40.
  • the main body 10 includes a first sound chamber 11 for receiving a front main speaker 21, a second sound chamber 12 for receiving a subwoofer 22, and a third sound chamber 13 for receiving a rear surround speaker 23, thereby forming a headset with a multichannel guiding mechanism.
  • the main body 10 can further include a fourth sound chamber 14 for receiving a middle speaker 24.
  • the cover portion 30 is attached to an outer side of the main body 10 for covering all of the sound chambers 11, 12, 13, 14 and the speakers 21, 22, 23, 24.
  • the ear contact portion 40 is attached to an inner side of the main body 10 and provides ears with a greater comfort.
  • the first sound chamber 11 is larger in size for installing the front main speaker 21.
  • the front main speaker 21 includes a treble area 211 in the middle thereof and a bass area 212 around the treble area 211.
  • an inner tube 111 for transmitting the treble and an outer tube 112 for transmitting the bass are disposed in the treble area 211 and the bass area 212, respectively.
  • the tube-in-tube (the inner tube 111 within the outer tube 112) arrangement in the first sound chamber 11 ensures an improvement of the sound quality.
  • the heavy bass speaker 22 is installed above the front main speaker 21. This is an optimal installation position for the subwoofer 22. Moreover, the subwoofer 22 within the second sound chamber 12 is disposed at a certain angle relative to a horizontal plane such that it is downwardly inclined to protect the human ears from direct exposure to the output sound wave and to create a surround spatial acoustic field for the user's ears.
  • the rear surround speaker 23 is disposed at an upper, a lower, or a central position behind the front main speaker 21.
  • the sound tube for installing the rear surround speaker 23 within the third sound chamber 13 can be extended as far as possible so as to create a sound wave delay effect. Since the sound passes through a long sound tube, more surround acoustic field will be produced and the surround sound quality will be enhanced. In order to make the elongated sound tube much longer, it can be formed in a curved shape. However, its shaped must not be restricted to the curved shape. In fact, the length of the sound tube is the key point of the surround effect. Since the internal room within the earphones 1 is much limited, the curved sound tube is therefore an optimal solution for a better sound effect without increase of the whole dimensions of the earphones 1.
  • the earphone 1 consisting of the front main speaker 21, the rear surround speaker 23 and the subwoofer 22 can reach multichannel sound effect by a special design of the separate sound chambers.
  • the middle speaker 24 is disposed at an upper, a lower, or a central position before the front main speaker 21.
  • the fourth sound chamber 14 for receiving the middle speaker 24 can be formed in a curved shape as well; however, the length thereof is much shorter than the third sound chamber 13 for receiving the rear surround speaker 23.
  • the internal structure of the fourth sound chamber 14 corresponds substantially to that of the third sound chamber 13.
  • the headphones of the invention take the sound transmission principles and the acoustic structure into account and feature separate sound chambers for different channel loudspeakers in accordance with their characteristics. Accordingly, all the loudspeakers can produce their unique sound quality and allow a clear positioning of their acoustic fields.
  • the sound chambers 11, 12, 13 designed in accordance with the characteristics of the front main speaker 21, the subwoofer 22, and the rear surround speaker 23 are integrated in an earphone 1, thereby allowing the front main channel (F) to have the treble area (H), the bass area (F), the subwoofer (W), and the rear surround channel (R).
  • a middle speaker 24 together with its sound chamber 14 is installed within the earphone 1 for creating a central channel, thereby forming a perfect 5.1-channel earphones with all different channel loudspeakers to show their own characteristics and achieving a clear, interference-free, and balanced reproduction of the original sound.
  • the dimension of the aforementioned earphones 1 of the invention can be reduced to form another embodiment of the invention.
  • a hook portion 2a for hanging the earphone 1 over the ear is provided for form a set of earphones without a headband 2 and similarly having several separate sound chambers.
  • the main body 10 includes a ear contact portion 40 that is tapered at the inner side thereof for adapting itself to the ear's shape.
  • the ear contact portion 40 is so big as an earplug and wearable over the outer ear.
  • the cover portion 30 is formed in a thinner way.
  • the first sound chamber 11 for receiving the front main speaker 21 is forwardly extended to form a slope.
  • the third sound chamber 13 for receiving the rear surround speaker 23 is also extended forwardly over a certain length so as to enhance the surround effect.
  • the other speakers as subwoofer, middle speaker and their sound chambers are designed as that of the aforementioned embodiment. Thus, no further descriptions are given hereinafter.
