Definitions
- the invention relates to a headphone with surround effect to widen the stereo base width or to create a natural-looking 3D sound effect based on a stereo audio signal or multi-channel audio signal (multichannel stands above, for example, for surround sound). Especially The invention relates to a stereo headphone with surround effect or surround sound headphones based on the inventive stereo headphones.
- a headset is either ear-enclosing (on-the-ear or in the ear canal) system educated.
- Go to the inventor of the present application numerous headphone developments in favor of a vorortortiana Listening events based on a stereo headphone back.
- This pre-location replaces the ones used head-to-head localization from sound sources, and the front-end location is achieved by arrangement the sound transducer starting from the usual central Position at the level of the ear canal forward and down added.
- Such a switched headphone generated in the ear canal Directional linear distortion effects accordingly the directional filter "outer ear or auricle" at frontal sound incidence. In other words it can be a natural surround sound similar for any headphone users generate the surround sound, which can be generated by means of speakers is.
- An object of the present invention is given This prior art therein, a headset of the beginning mentioned type with simple means in such a way, that the reproduction of stereo sound signals or multi-channel sound signals (Surround sound sound signals) an improved, of course ensuring a pleasing space for the headphone user.
- each of at least one transducer pair a improved, natural-looking space when using headphones Ensures that each a sound transducer of the decentralized transducer pair with the original one Stereo audio signal is applied while the other Sound transducer of the decentralized transducer pair with the other Stereo sound signal is applied, but one Phase rotation and / or subjected to a level reduction becomes. In particular, this can be done without any electronic effort an improved natural-looking space for headphone reproduction be achieved.
- a stereo headphone builds up by the measures according to the invention in addition the normal "left / right" listening level a "front / back" listening level and another listening plane, which is essentially “vertical or vertical” runs.
- the listening level "front / back" comes then pronounced to the effect, if with an overhead sound transducer and a lower transducer, based on the normal Sound transducer position in front of the auditory canal, the upper one Sound transducer of the decentralized transducer pair around one predetermined amount is offset horizontally to the rear, while the downstairs sound transducer by a predetermined Amount is shifted horizontally forward.
- the decentralized transducer pair with top and bottom lying Sound transducer is preferably the lower sound transducer charged with the original stereo audio signal.
- Phase rotation which in one of the two arranged decentrally Sound transducer is provided according to the invention, is preferred essentially 180 °.
- phase rotation of 180 ° can be achieved by an extremely simple measure namely by swapping the hot and the cold conductor a usual two-wire signal line, the sound signal feeds the sound transducer.
- the inventively provided for natural Jardinklangeinrial contributing level reduction of the audio signal is at least two dB, preferably six to twenty dB. These Level reduction can be easily achieved by an actuator, achieved for example in the form of a potentiometer become.
- This level reduction potentiometer is preferred as Stereo potentiometer designed with which the level reduction "left” and "right” in the respective earpiece simultaneously is effected.
- Stereo headphone is the design of the scheme the additional transducer analogous to the design and Control of the sound transducers of the stereo headphone met, which are explained above.
- FIG. 1 the two headphone capsules of an inventive Stereo headphone shown. These capsules have oval Shape up.
- the headphone capsule designated by the reference numeral 1 puts the left earphone capsule of the stereo headphone and the headphone capsule designated by the reference numeral 6 makes the right earphone capsule of the stereo headphone
- the reference numeral 2 is a part of a headband denoted by a joint 5 with the left earphone capsule 1 is connected. A corresponding connection exists between the headphone strap 2 and the right earphone capsule 6 (not shown).
- Each headphone capsule 1, 6 is according to the invention with two Sound transducers fitted. Accordingly, the left earphone capsule 1 with a sound transducer 3 and a sound transducer 17th equipped and the right earphone capsule 6 is with a Sound transducer 7 and a transducer 8 fitted.
- the Sound transducer 3, 17 and 7, 8 of the respective transducer pair are decentralized with respect to a normal one central sound transducer position in front of the auditory canal of a user pipe, which sound transducer position is normal in that It is used with conventional stereo headphones.
- the two transducers 3, 17 and 7, 8 are at least at about the same distance from the central sound transducer position, which coincides in the illustrated embodiment with the joint of the headphone capsule (in the case of the left Capsule in the joint 5).
- the respective lower sound transducer 3, 7 of the transducer pairs 3, 17; 7, 8 is with respect to a perpendicular C in the viewing direction a headphone user offset forward, during the associated sound transducer of a Schallwandlercompetes the sound transducer 8 and 7 by the same amount in the direction a headphone user is offset to the rear.
- the centers of the sound transducers 3, 17 in the case of the left capsule
- the clockwise from the perpendicular C by the angle ⁇ is turned.
- This angle ⁇ although not in the drawing also exists between the horizontal and a straight line A, which cuts the straight line B at right angles.
- the straight line A turns clockwise twisted horizontal, starting from a horizontal Position below 90 ° to the vertical C.
- the sound signal supply device 9 to 11, 16 consists of a connector 16 with a hot Tonsignalanschluß R for the right channel and a hot Tonsignalanschluß L for the left channel, additionally with "+" designated. Furthermore, in the connection part 16 there is a minus or ground terminal, the reference potential for both hot connections R and L forms.
- the connections R, L and Grounds are via a wiring network with the sound transducers 3, 17; 7, 8 connected. In this case, a line 9 leads the hot Sound signal for the right channel, a line 10 hot Sound signal for the left channel and a line 11 for the Ground connection to the sound transducers.
- each of the lower Sound transducer of the decentralized sound transducer pairs 3, 17 and 7, 8 with the original sound signal of the left and right channel 1: 1 is supplied.
- 1: 1 means in original Phase position as well as with original level. Accordingly, it is the lower transducer 3 of the left capsule 1 in phase connected to the terminal R and ground of the terminal part 16.
- the underlying sound transducer 7 is the Right capsule 6 in-phase connected to the left terminal L and ground in the connection part 16.
- the overhead sound transducer 7 serve or 18 as a kind of space-effect channels, for a provide a pronounced 3D sound.
- These overhead transducers 8 and 17 are rotated by a 180 ° phase with connected to the terminals in the connection part 16 and also over Cross connected with respect to the left and right channels. That is, the overhead sound transducer 17 of Capsule 1 is powered in phase with the right tone signal and the overhead transducer 8 of the capsule 6 is phase-locked with the left tone signal from the connector 16 provided.
- phase position of the respective sound signals goes out of the drawing through schematic sine wave components, the before the right stereo headphone capsule with the reference numerals 12th and 13 are designated.
- the surround sound effects channels provided by the overhead transducers 17 and 8 of the two capsules 1, 6, are also according to the invention in terms of their level adjustable, over a range of preferably 6 dB up about 18 dB, and at least 2 dB by means of potentiometers 14, 15, lying in their "hot” leads. This will be the phase-turned and cross-connected to the overhead Sound transducer 17, 8 applied respective sound signal to the original Left-right sound signal mixed in a way and Way that results in an improved surround sound impression.
- switches that are in series are connected to the potentiometers 14, 15 for level adjustment. These switches ensure that the effect channels, i.e. the over the overhead transducers 17, 8 radiated sound signals on and off so that the user can assure himself of the effect at any time can, by the additional sound transducer 8, 17 provided.
