Abstract

A microphone device includes a base adapted to be installed in a given position, an arm mounted on the base for angular movement in a predetermined angular range with respect thereto, and a sound pickup unit mounted on a distal end of the arm for picking up sounds when the arm is angularly positioned at a predetermined angle with respect to the arm. The base may be installed on a pillar positioned obliquely in front of the driver'"'"'s seat of a motor vehicle, so that the microphone can be held in a good position with respect to the driver. The microphone is positioned in superposed relation or in the vicinity of the pillar that is present in the front vision of the driver on the driver'"'"'s seat, and hence does not essentially interfere with the front vision of the driver.

2. The navigation system according to claim 1, wherein said microphone assembly further comprises:

said base installed on said pillar;

said arm mounted on said base for angular movement over a predetermined angular range with respect to said base; and

said sound pickup unit mounted on a distal end of said arm.

3. The navigation system according to claim 2, wherein said arm is spaced apart by a predetermined distance from said pillar to form a gap when said arm is angularly positioned substantially parallel to said pillar.

4. The navigation system according to claim 2, wherein said microphone assembly further comprises switch means mounted on said arm proximate said sound pickup unit for effecting a predetermined operation on the navigation system upon manual actuation thereof.

5. The navigation system according to claim 2, wherein said arm and said sound pickup unit are located substantially within a space defined by a width of said pillar as viewed from the driver seated on the driver'"'"'s seat when said arm is angularly positioned most remotely from said pillar.

6. The navigation system according to claim 2, wherein said arm is angularly movable out of said predetermined angular range when subjected to an external force beyond a predetermined level.

7. A communication device in a motor vehicle for effecting radio communications with a radio station, the motor vehicle having a driver'"'"'s seat and a pillar positioned obliquely in front of the driver'"'"'s seat, the device comprising:

a microphone assembly pivotally mounted on the pillar for movement between a first position substantially parallel to the pillar and a second position substantially perpendicular to the pillar, wherein the microphone assembly in the second position does not interfere with the vision of a driver in the driver'"'"'s seat, for picking up a voice sound from a driver and processing the voice sound for transmission to the radio station through radio communications; and

wherein the microphone assembly includes a base mounted on the pillar, an arm pivotally attached at one end to the base, and a telephone hook switch housed in said base for controlling communication which is activated in response to movement of the arm into the second position.

8. The communication device of according to claim 7, wherein said microphone assembly further comprises:

said base installed on said pillar

said arm mounted on said base for angular movement over a predetermined angular range with respect to said base; and

a sound pickup unit mounted on a distal end of said arm.

9. The communication device according to claim 8 wherein said sound pickup unit is selectively energized and de-energized in response to said activation of said hook switch.

10. The communication device according to claim 8, wherein said arm is spaced apart by a predetermined distance from said pillar to form a gap when said arm is angularly positioned substantially parallel to said pillar.

11. The communication device according to claim 8, wherein said microphone assembly further comprises switch means mounted on said arm proximate said sound pickup unit for effecting a predetermined operation on the radio communications upon manual actuation thereof.

12. The communication device according to claim 8, wherein said arm and said sound pickup unit are located substantially within a space defined by a width of said pillar as viewed from the driver seated on the driver'"'"'s seat when said arm is angularly positioned most remotely from said pillar.

13. The communication device according to claim 8, wherein said arm is angularly movable out of said predetermined angular range when subjected to external forces beyond a predetermined level.

14. An audio device in a motor vehicle for outputting an audio signal from an audio signal source through a loudspeaker, the motor vehicle having a driver'"'"'s seat and a pillar positioned obliquely in front of the driver'"'"'s seat, the device comprising:
