Description

HEADREST CONTAINING LOUDSPEAKERS FOR MOTORCAR FIELD OF THE INVENTION
The present invention relates to a headrest for motorcar, particularly to a neadrest containing loudspeakers therein by which it is made possible to provide a quiet and distinct sound for passenger.
DESCRIPTION OF THE PRIOR ART
In prior art, loudspeakers of an audio system for motorcar have placed in a right side and a left side of a front compartment and/or a rear compartment for a driver and passengers. Therefore the loud- speakers is relatively remote from the occupants who listen the sound transmitted from them. The sound from loudspeakers which is mounted in the compartment so that they can listen the sound such as music a announcement. Heretofore, there is no system from which the sound can be transmitted to a specific individual. Moreover, in case of an ownerdriver, it is desirble for him that the loudspeakers are mounted to a place adjacent to his ears in order to listen a quiet music as being transmitted from a headphone and drive the motorcar without missing a circumstantial judgment regarding to the driving.
Also, it is known that an audio system for motorcar is provided with loudspeaker which can be shifted in places. But, since the loudspeaker is exposed in the inside of motorcar, the loudspeaker is a hindrance for the driver or passengers, and the loudspeaker is not fixed so that one cannot expect to a good acoustic efficiency from it.
The applicant have found that it is desirable that the loudspeakers are housed in the inside of a headrest
SUMMARY OF THE INVENTION
An object of the present invention is to obviate the drawbacks of the prior art and to provide a headrest containing loudspeakers therein by which it is made possible to provide a quiet and distinct sound for a driver or passengers. In general, the headrest is provided with a frame to which two connecting rods are mounted, the connecting rods connects the headrest to the back of seat. The loud- speakers may be housed in the headrest using the frame. When the loudspeakers are housed in the headrest, the loudspeakers may be placed to adjacent to the ears so that one can listen a quiet and distinct sound from them even in low sound pressure level.
The present invention will become clear from the following description of the invention and with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is a perspective view of speaker units and a frame of headrest according to the present invention.
Fig. 2 is a cross-sectional view of the headrest according to the present invention. DETAILED DESCRIPTION OF THE INVENTION
In drawings, a headrest 10 is comprised of a frame 12, an enclosure 14 defining a space 16 with the frame 13, and an outer pad 13 covering the frame 12 and the enclosure 14. The frame 12 has a mount 20 at which a pair of clips 22 and 22' are attached for connecting a pair of connecting roos 24 and 24'. An upper bent end of connecting rods 24 and 24' is clamped of the clips nespectiveiy and the connecting rods connect the headrest 10 to a back of seat (not shown).
The frame 12 is formed with two circular holes 26 and 26' for attaching two speaker units 28 and 28', respectively. The speaker units 28 and 28' is housed in the space 16 with attaching at the backside of frame 12.
In a front portion of the headrest, two acoustic guide-holes 30, of which one is shown in Fig. 2, are opened at the outer pad 18 such that each of acoustic guide-holes 30 is aligned with each of the circular holes 26 and 26' of frame 12 and the speaker units 28 and 28' housed in the space 16.
Speaker units 28 and 28' are attached to the backside of the circular holes 26 and 26' which are formed at the frame 12 so that the speaker units 28 and 28' are firmly supported by the frame 12 and protected from vibration. Therefore, speaker units 28 and 28' can transmitt a stable sound to passengers. And the space 16 act as an acoustic enclosure causing to rise the acoustic efficiency of speaker units. 'Moreover, speaker units 28 and 28' according to the present invention are attached to the frame 12 with spacing each other so that the sound produced from speaker units is separated to enhence the stereophonic effect and transmitted to the passenger even in iow volume. Therefore passenger can listen the stereophonic souno with his head leaning against the headrest and delight in music without bothering a neighbor.
Since the speaker units are housed in the inside of the headrest, the speaker units cannot hinder the passengers from occupying the seat. The outer pad 18 covering the frame 12 is made of a foam material such as sponge and a cloth to have a permeability for transmitting sound from the speaker units.
In this manner, the headrest containing loudspeakers according to the present invention is made possible to provide a quiet and distinct sound for passengers and provide an advantage of arrangement for the speaker units without exposing out of the headrest.
It will be appreciated that the present invention is not restricted to the particular embodiment described hereinbefore, and that variations and modifications may be made therein without departing from the spirit and scope of the invention.
