BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a device for mobile telephone apparatus, comprising at least one loudspeaker and at least one microphone arranged in connection with a headrest, the loudspeaker and the microphone being connected to the mobile telephone apparatus.
In the field of mobile telephones, there is a demand for allowing the user to use the telephone while at the same time having both hands free, particularly in order to be able to drive the vehicle in a safe manner. This is particularly the case in connection with so called "duplex" transmission, i.e. where signal transmission via the mobile telephone is carried out in two directions simultaneously.
A device which is directed towards this demand is previously known from patent document EP 0368291, which shows a mobile telephone apparatus with a loudspeaker 6 and a microphone 3. The loudspeaker 6 is integrated in the headrest, whereas the microphone 3 may be arranged either on the sun visor or on a flexible arm which is attached under the roof.
Another device of a similar type is known from Swedish patent no. SE 467681, in which an existing headrest may be provided with a separate loudspeaker unit comprising a loudspeaker element and a microphone.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an improved device for use in connection with mobile telephone apparatus, which device allows the user's hands to be free while at the same time providing an easily exchangeable unit which may be arranged on an existing vehicle seat. This is achieved by means of a device of the abovementioned type which is characterized in that the loudspeaker is integrated in the headrest and that the microphone is arranged on an arm, which arm is attached to the headrest.
Accordingly, the present invention provides a device for a mobile telephone apparatus having at least one loudspeaker and at least one microphone arranged in connection with a headrest. The loudspeaker and the microphone are connected to the mobile telephone apparatus. The headrest is adapted to be removably arranged on a vehicle seat. The loudspeaker is integrated within the headrest and the microphone is arranged on an arm which is attached to the headrest.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a mobile telephone apparatus in accordance with the present invention;
FIG. 2 shows the device in accordance with the invention in an assembled state;
FIG. 3 shows a side view of the present invention with the arm in its lowered position; and
FIG. 4 shows a front view of the present invention.
DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
The invention will now be described in greater detail with reference to the annexed drawings, in which FIG. 1 shows the invention in a dismounted state, FIG. 2 shows the invention mounted on a vehicle seat, FIG. 3 is a side view and FIG. 4 is a front view of the invention.
FIG. 1 shows a preferred embodiment of the invention, which is primarily intended to be used in connection with a mobile telephone apparatus in a vehicle. The invention comprises a removable headrest 1 intended to be mounted on a vehicle seat 2. Inside the headrest 1 there is arranged at least one loudspeaker element 3 which is preferebly placed adjacent to one of the user's ears. Two separate loudspeaker elements may of course be arranged adjacent to the user's respective ear. The loudspeaker element 3 is provided with connections (not shown) which are connected to the wiring 4, which in turn is connected to the fixed part of the mobile telephone apparatus via the connector 5. The fixed part of the mobile telephone apparatus may be arranged on the vehicle's dashboard in a conventional manner.
A microphone 6 is arranged on a flexible arm 7, preferably at its end section. The arm 7 is rotatably mounted on the headrest 1 via a pivotal joint 12, the axis of rotation of which is essentially perpendicular to the longitudinal direction of the vehicle seat (and the headrest 1) and also essentially parallel to the upper side of the headrest
