Definitions
- the invention relates to a headphone with left and right support elements for a sound transducer.
- Headphones are known in supra-aural or circum-aural design in which the transducer is disposed in a baffle forming, among other things, its support member within left and right, half-open or closed earphone shells attached to and destined to the ends of a headband Headphone pads on the head of a headphone user either on its ears (supra-aural) or surrounding it (circum-aural).
- each baffle carries a single sound transducer in its center, so that sound emitted by it is radiated essentially in the direction of the baffle normal.
- a disadvantage of this classic centric arrangement of the transducer is that it favors the in-head localization of the sound event generated by the headphones.
- a disadvantage of these known headphones with reduced in-head localization is that due to the largely predominantly by reflection on the skull of the headphone user and his outer ears fed into the ear canal sound and mid-tone losses occur individually depending on the head and ear shape of the User are more or less pronounced, which not least leads in practice to the fact that the sound level at the expense of hearing is chosen excessively loud.
- An object of the present invention is therefore to provide a headphone of the type mentioned, which gently protects an improved out-of-head localization of sound events without significant high and mid-tone losses guaranteed.
- An optimized suppression of the in-head localization of sound events in favor of an out-of-place localization with predominant sound events perceived by the front through the sound guide according to the invention is achieved in that the sound center of the sound transducer relative to the inlet the ear canal of a headphone user in addition to its tilting about two axes with respect to the support member down and predominantly comes to lie forward.
- the sound guide body may have different shapes. Particularly preferred is a funnel-shaped and alternatively a tubular sound guide body. When funnel-shaped sound guide body of the transducer sits at the tip end of the funnel, which provides over its opposite, wide open end a large sound outlet opening, which allows to sonicate in addition to the entrance to the ear canal a large part of the outer ear.
- the tubular sound guide body allows the targeted sonication of a smaller ear area and also allows the use of several connected to the support element sound guide bodies by means of several tilted and staggered transducers.
- each support element including the sound guide body or the sound guide bodies as a one-piece injection molded part, preferably made of plastic.
- 1 is a plan view of the side facing away from the ear of a headphone user side first embodiment of a equipped with a single transducer transducer support member of the headphone according to the invention with a transducer accommodating tubular sound guide body
- 2 is a side view of the support member / transducer assembly of FIG. 1,
- FIG. 3 shows a plan view of the side facing away from the ear of a headphone user side second embodiment of a paired with two transducers transducer support element of the headphone according to the invention with two the two sound transducer receiving sound-conducting bodies,
- FIG. 4 is a side view of a support element / sound transducer arrangement of Fig. 3,
- FIG. 5 is a plan view of the directed to the ear of a headphone user side of a third embodiment of a equipped with a single transducer transducer support element of the headphone according to the invention with a transducer accommodating funnel-shaped sound guide body,
- FIG. 6 is a sectional view taken along the line A-A of the support member / transducer assembly of Fig. 5,
- Fig. 7 is a sectional view taken along line A-A of the support member / transducer assembly of Fig. 5, and
- FIG. 6 is a plan view of the Schallabstrahlseite the arrangement of Fig. 5th
- the left earphone shell is mirror-inverted to the arrangement shown in FIG.
- the support element 9 comprises a flat disc 10, at the circular edge of which an ear cushion (not shown) is arranged, and a hollow sound guide body 13 in the form of a tube with a circular cross section, the longitudinal axis 12 of which extends obliquely or tilted towards the disc 10.
- the tubular sound guide body 13 opens with one end in an eccentric elliptical breakthrough in the disc 10 and carries at the other end of the transducer 11, which has a general circular disk shape and whose longitudinal center axis is aligned with the longitudinal axis 12 of the sound guide body 13.
- the center Z of the support element disc 9 is located at the level of entry to the auditory canal of the right ear of the headphone user where conventional sound headphones the sound transducer is positioned. Starting from this central position, the center Z 'of the sound transducer 11 comes by the distance a on the horizontal axis H in Fig. 1 by the center Z to the right corresponding to the viewing direction of the headphone user and the distance b on the vertical axis V through the center Z to be offset down.
- the sound transducer 11 with respect to the support element disc 9 resulting in a corresponding tilting of the tubular sound guide body 13 so tilted about a vertical axis parallel to the vertical axis V and a horizontal axis parallel to the horizontal axis H - which means that the sound transducer (11, 14, 20) assumes a position tilted about a horizontal axis in the direction of viewing of a headphone user and a vertical axis intersecting the horizontal axis - that sound generated by it is aimed specifically at the right ear of the headphone user, in the case illustrated in FIGS. 1 and 2 the entrance to the auditory canal.
- the tilting and the displacement of the sound transducer with respect to the center Z of the support element disc 9 may be selected such that a larger part of the outer ear is specifically sonicated.
- the arrangement of the sound transducer 11 on the support element 9 according to FIGS. 1 and 2 and the mirror-image configuration of this arrangement on the left ear ensures a significant reduction in the in-head localization of sound events found in conventional stereo headphones in favor of out-of-head localization, especially the head-to-head localization of sound events.
- this type of sound for the headphone user produces an extremely clean, finely resolved and spatial sound based on the sound events reproduced by the headphones.
- FIGS. 1 and 2 show a modification of the support element / sound transducer arrangement of FIGS. 1 and 2 for sounding the left ear of a headphone user provided, in addition to the sound transducer 11 'in the position mirror image of the sound transducer 11 in Figs. 1 and 2 another transducer 14 eccentrically and tilted on the support element disc 10 'of the support member 9' is arranged. Starting from the center of the support element disc 10 'comes the additional transducer 14 predominantly up and forward offset over the transducer 11' to lie.
- the other transducer 14 is tilted on the support element disc 10' arranged so that the sound transducer 14 in Schallabstrahlraum centrally passing longitudinal center axis 15 as well as the longitudinal center axis 12 'of the transducer 11' in the direction of the entrance to the ear canal of the headphone user has.
- the support element / Schallwandler- arrangement shown in Fig. 6 to 7 for sonication of the left ear of a headphone user of the headphone according to the invention is a single transducer 20 in a tilt / offset position mirror image of that in Fig. 1 and 2 are used, the tip end of a funnel-shaped sound guide body 21 is seated, and with his wide open end in an oval inner edge 23 of a support element disc 22 of a support member 19 opens. Accordingly, the sound center of the sound transducer 20, in relation to the entrance to the auditory canal of a headphone user, comes down on its left outer ear via a support element disc 22 of the stereo headphone not shown above.
- the support element disc 22 and the funnel-shaped sound guide 21 form a one-piece injection molded part, preferably a plastic injection molded part, which at the outer edge of the support element disc 22 also includes a rearwardly projecting stabilizing collar 24 with a cable passage opening 25 and a circular arc-shaped flange 26 for connecting a headphone bracket, not shown.
