Abstract

To avoid the disadvantages of known headsets, and in particular to ensure comfortable use, a sound playback system for wearing as a headset (1) is equipped with at least one sound source (3) for example a small speaker, in which the sound source (3) or sources (3) is (are) combined with a soft head piece (9) or overlay, and a connection (5) is incorporated therein for a tape recorder.

Description

assigned to the head of a person audio playback device

The invention relates to a the head of a person designated zugeord¬ audio playback device with at least one Schäll¬ source, such as a speaker.

The known headphones have a range of len Nachtei¬. This includes in particular that the headband are un- beqehm, bulky clothes hindrance and yet an un¬ desired influence or pressure .. in the free Bewe¬ supply to the head and especially the pinna field exercise. Even their close 'pinna system often results in unwanted heat and perspiration in the area around the ears.

Although there are known non-iron headphones, but having to headphones be made very small to be trapped inside the entrance of the ear canal to. Creating an unpleasant pressure at this point occurs, so that they will not be able to be used in succession as well. In addition, the ears of the person DER surrounding noise are completely soundproof completed, so that the user of which is totally disconnected and eg is not any more or any risk-noise can not perceive.

Two known headphone forms nor the downside is like lonely also that it more or less completely block the auditory canal so that the natürli¬ che air circulation in this area is not possible.

Above all, it is with these known Kopfhörer¬ forms for the above reasons very unbeqehm. this lying eg for plant or support of the head - to use it on a soft pillow, so that in lying ent stressed form, because, especially in a lying position on the side of the head, the pressure on the pad ear is unbearable while at the other ear, the reproduction for a to both ears of uniform thickness Ton¬ necessary firm contact is not provided on the auricle area.

pillow speaker also cause other, flat-shaped unilateral so-called head either unerträg¬ union bearing pressure on the head or the ear or act -. located beneath the pillow - too dull and too low and are especially suitable for stereo playback.

Object of the invention is to provide a the head of a son Per¬ associated audio playback device that avoids these drawbacks, ie in particular allows sound reproduction really relaxed and beqehmer Kopfanläge. Above all, will the. erfindungs¬ contemporary furnishings and for use for children or be suitable as a toy.

Accordingly, the invention is characterized by the combination of at least one sound source, for example a loudspeaker, in particular a small or headphone loudspeaker with a soft head unit or head rest, sowieeiner-- so An¬ integrated circuit on a tape recorder.

Here, the sound source transformer as Schwingungsdruck¬ - similar to the verwen- of airlines *: Deten headphones - to be formed, wherein the means of a flexible hollow conduit to the ear DES user über¬ transmitted Tonschwingύng either in an auxiliary device for tape recorder or is integrated in the tape recorder itself generates.

Preferably, the sound source is within the Kopf¬ plant ,. for example, a pad or a head part, close to its *. Kopfanlageόberfläche arranged.

usic for also stereo moderately reproduced sounds, for example, or surround sound reproduction is least two sound sources arranged according to the invention at min¬ each one of which is reasonable in one of the sound to the respective ear of the person passtem distance on both sides of Kopfanläge- or head contact area.

In detail, the Kopfanläge or Kopfaufläge as a pillow, preferably formed as an elongated pillow or head roller, wherein the sound sources near the ears of the user side of hin¬ th or angularly turn by the pad or roller under the head pad printing comparable forms and areas of their protruding laterally from the head terminally high arch.

A so-called. Quadro-effect, ie an improved Raumklang¬ effect can be achieved in that two sound sources are provided on both sides of the Kopfanläge or Kopfaufläge, and indeed in pairs longitudinally arranged to the body of the person distance from each other, wherein the sound sources laterally above and below each ear. In this case, each of the four corners of a pillow beneath the head contact pressure arch to the head of the user. An increased attention of the sound sources in the direction parallel to the ears arrangement can himself erajeichen when the sound emission direction of the sound sources within the head unit or Kopf¬ pad is directed obliquely on both sides in the direction of the head aus¬.

In the sense of said tape recorder also each ande re reproducing apparatus such as disk player or radio with the invention is applicable.

Ensuring the local Läge of the sound sources can take place in that the sound sources positionally or in the filling of the cushion are fixed .. of the roller, the sound sources are in addition to Kopfanlage- or head support surface covered back with a thin cushioning layer - which preferably directly durchge Henden sound passage openings is provided.

In order to avoid slipping of the sound sources within the Kis¬ sens or role is also contemplated that the sound sources are fixed to the inside of the Kopfanlage- or head support surface.

A further improved sound is given when the Kopfanläge- or head support surface in Ab¬ deck area of ​​the sound sources with large pores, preferably is formed net-like.

Cheap allocations of the sound sources arising he find in accordance with when the pad or the head roller has articulated elements on both sides of the head, with those where the side portions of the pad or roller un¬ ter head contact pressure amplified facing the ears wer¬ the.

In another embodiment, the central portion of the Kis¬ sens or the roller may be smooth or, preferably, thinner than their more preferably aufge¬ arched side parts.

An amplified high curvature of the side portions of the pad or roller may also be achieved by be¬-actuated from the head-pad printing devices, for example, when an air bubble is provided within 'the pad or roller in its central part, which with air bubbles in both side parts in connection, where the air is displaced below the head contact pressure in each case in the side parts and these are highly curved on its base.

To facilitate the high curvature of the side portions of the cushion or the role they may have a material reduction in the head-facing Knickbereich- and at the respective back to a zone erleichter¬ ter Materialstrecküng or Expanse have.

For holding the Tonwiedergabeein¬ device according to the invention, the invention provides that on bei¬ the sides of the head unit or head rest two sound sources are provided 'respectively, namely in pairs along arranged to body of the person distance zueinan¬ of where the sound sources laterally above and below each ear.

If the connection for the tape recorder as a socket attached to the pad or roller, then the holding force of the plug in the socket can ein¬ set such that the connecting cable automa¬ from the pad solves table as soon as a higher train is applied thereto , for example when accidental winding around the head - or the neck of the person - by the Anschlu߬ cable. In addition, the pad or roller may be used in this form without the connecting cable. ;

In order to keep the holding force of the plug and also better controlled to disable a print option by the plug on the person's head, respectively according to the of invention should also connection for the plug into the profile of the pad; be the role countersunk. Similarly, such a safety separation device may also elsewhere in the Union or the connecting cable can be provided for tape recorder.

For automatic switching of the sound sources depending on the head position, a switch can be mounted according to the invention within the pad or roller with which the sound sources for displacement of the head dergabe on one of the side areas of the pad or roller to mono How-alone on the pressure moderately from the head te side beaufschlag¬ switchable are.

To automatically compensate for even small displacements head on the pillow or the roller, in addition, can Be¬ area of ​​the system or pad of the head be a Vor¬ direction provided with which the Sterep effect depending on a given head rest between the left and right of head arranged sound source is variable or adjustable center (automatic balance control).

In an advantageous modified form, a generic erfinde¬ use of the fact that the figure as Kopfanläge Symbol¬ z. B. dolls - animal or fantasy character is formed. When installing the sound source in z. B. ei¬ nen teddy bear or a puppet figure or derglei¬ chen, can be educational effects such Märchenwieder¬ reproducing etc. for children - even falling asleep - or achieve a playful communication of subject matter, specifically including language teaching. A switched to die¬ se manner by subject matter such. As a wei¬ chen stuffed animal as a reference entity is considered significantly leich¬ ter and more thoroughly by children. In order to enable a stereo reproduction via Schmusetiere for Kin¬ of a sound source may be located respectively in the two hands or feet of the figure, the figure having an arm length, with which the two sound sources collapsing to a respective ear of the benüt¬ person can be held. So that the effect is achieved that the child feels embraced simultaneously by sei¬ ner "favorite character". By a Schal¬ ters possibly a short-return switch or Lauf¬ speed change, the child can the Tonwiederga¬ begeschehen follow relieved.

In this case also a combination of several, more particularly two sondere dolls (eg. Kasperletheater) can verwirk¬ union, which indeed have a sound source, which separated from each other with one of * Stereo ribbon. Zwiege¬ sprächsstimmen be controlled on each track. Mit¬ means of a switch for turning on and off of the tape device Ton¬ within one or both can be carried out arbitrarily in Doll da¬ dergabe even a temporary interruption of the Bandspurwie¬.

The invention is described below in more Ausführungsbei "play described in detail.

In accordance with the figures 1-8 are in a Kopfanläge - or auflage¬ surface with schematically given head of a person with -Ohren 4 on both sides Chern 8 sound sources 3 in the form of, for example, speakers, especially Kleinlautspre¬ at a certain distance or incorporated headphone heads or . stored.

In this case, the distance between which is dimensioned such 8 from the head 1 so as to position of the rear side on both sides of the region C of the An¬ or support of the head 1 are arranged to form a op¬ timale sound to the ears of the person 4 of the head 1 to ensure that is not obscured by the head 1 or shaded and the head 1 is also not limited to a possible be¬ to close contact or contact area C, but uf rests the back of the head. '

The Kopfanläge- or supporting surface 2 can .or as a head roll 10 (so-called. Bolster) as a pillow 9 (. Fig. 1 and 2, and Fig. 4) or in particular to the invention ab¬ asked mold (10 ') formed be , Within the Kopfanlage- or head support surface 2, not only the sound sources 3, but also their dung Verbin¬ lines 6 in the filling 24 or also in their Rarid- mounted sewed laid, and the female terminal 5k; namely der¬ art that they do not impair the convenience of Kopfanläge- or auf¬ bearing surface 2, including the Anschlu߬ socket for the tape recorder 5 in sunk least hinderli¬ cher location within the Kopfanlage- or au bearing surface 2 arranged is.

The laying of the connecting lines 6 should be fixed within the filling of the pillow or the roller 24 such that even for example by a crumpling of the head roller (bolster) 10 neither on the sound source 3 nor to the socket 5 is a destructive train can arise.

The connection to the tape recorder 35 via an insertable into the connection socket 5 plug of a Anschlußka¬ bels 29 and may be strength adjusted in accordance with the fact that the plug at a higher tensile stress on the An¬ slipping connection cable 29 by itself, so that a comparison schlingungsgefahr for may use for person is off.

When the connection lines 6 without separate Anschlu߬ bush 5 contact or of optionally reinforced place of Kopf¬ support surface 2 are led out of this and go directly to the connecting cable 29, then a similar safety separator in Anschluβkabel 29 may be provided. At the connection points to the connection socket 5 and the sound source 3, the Verbindungsleitu gen 6 zusätz¬ Liche loops may have a tear-off or • Bruchge¬ moving at this point to avoid the "bunching" of the pad.

This applies both to the execution as a pillow 9 (ins¬ particular Fig. 2), as well as the head pulley 10 and also those shown in Fig. 4 case in which gleich¬ sam the four corners of the preferably "elongated Kis¬ sens 9 separately on each side above and below the respective tube 4 this zuwölben and thus the - in this embodiment - are arranged in pairs on each side of the longitudinal distance 11 from sound sources 3 to the tube 4 with appropriate Tonwiedergaberichtung or sound-Abstrahl¬ direction 12 approaching

In order to increase this effect, the Kopfanlage- or support surface 2 in three parts connected Intended manner in accordance with such can. B. FIGS. 5 and 6 formed form ausge¬ leads his, wherein the average upward and contact region C are either softer and / or thinner than the side areas of the pad or roller A and B for the head 1 '. A similar structure, by forming the Kon¬ 24 consistency of the filling in the through pillow 9 or the head roller 10 are present. The effect of the kink regions 22 is still being ausgespro¬ chene kink elements 14 (Fig. 7) improves, which may have on the opposite side a Ma¬ terialverminderung 20 at the towards the head kink region 21, and a zone .erleichterter material stretching 23rd

Characterized the side parts of the pad 16 (or A + B) reinforced on both sides from the central portion of the pad 15 hochge¬ bulges.

For fixing the Kopfanlage- or support surface 2 at the upper part of the backrest of a seat (for example, passenger seat in a motor vehicle) can fasteners 27, beispiels¬ example in the form of bands or the Velcro fastener on the rear side of the Kopfanlage- or its contact surface 2 is provided.

Another type of gain of the high curvature of the side portions 16 of the pad (10 *) is shown in Figure 8 in which an air bubble 17 is mounted within the filling 24 in the central part of the pad or roller, which is in direct communication with air bubbles 18 is in each case in the side parts 16, which tightly fill under the head pad and the pressure Seiten¬ parts 16 against the base 19 high arch. Instead of a Luft¬ filling in the bubbles, water can also be used in special cases σgfalls.

The sound sources 3 and the loudspeakers are close to or disposed near the coverage area 26 within the Kopfanläge- or supporting surface 2 and preferably on the emission side Schall¬ covered with a lightweight cushion layer 25th Here, the sound sources 3 may be mounted stationary or elastic, either alone or combined within the filling 24 in conjunction with the cover portion 26 or so. For better and ungedämpfteren Schallabstrahlu g neither the cushioning layer 25 may be perforated in the area in front of the sound sources 3 with small Löqherπ and / or finished in rough porous or mesh-like form 26, this area of ​​the cover ent.

For improved alignment of the direction angle 13 of the sound emission direction 12, the sound sources 3 may also be arranged in a ears 4 more facing position within the filling 24, that is, obliquely to the surface 7 of the Kopfanläge¬ or supporting surface 2 '(Fig. 8), namely un¬ ter adjustment of. said distance. 8

For example by means of a pressure-responsive switch 30 is confined within the filling 24 of the side parts 16 in Ver¬ storage of the head 1 in its lateral position, the sound on only this one then applied to the head 1 Schall¬ source 3 and automatically ggnfalls of stereoisomers switched to mono mode.

Also, a device can in the Kopfanlage- or auflage¬ surface 2 to be installed, which causes an automatic volume control of both sides are arranged from the top of sound sources 3 with only a small displacement of the head 1, that is, works as an automatic balance control, so that in this the case remains the central stereo effect. The tape recorder 35 used should be an automatic

own limit switch, as well as at its terminal 28 and a recessed from one side accessible, Vsteckerbereich 36 have auf¬, so that the connector does not protrude beyond the contours of the device disturbing addition.
