Abstract

A bone conduction microphone assembly with a transducer mounted in a transducer mount supported from a surrounding support member by spring means which yieldably urges the transducer mount against the user'"'"''"'"'s head with predetermined pressure.

Claims

1. A bone conduction microphone assembly comprising an acceleration sensitive transducer, a transducer mount adapted to receive and hold said transducer, a transducer support having an opening larger than said transducer mount for receiving said transducer and mount, said support surrounding and spaced from said transducer mount and a plurality of spring means connected between said transducer mount and said transducer support to hold the transducer in said opening and yieldably urge the transducer against the head of a user with predetermined pressure when the transducer support rests against the head of a user.

2. A bone conduction microphone assembly comprising a transducer mount having upper and lower surfaces, a transducer of the type which provides an output responsive acceleration held in said mount, a support having upper and lower surfaces and an opening larger than said transducer mount for receiving said transducer and mount, said support surrounding and spaced from said transducer mount, spring means extending between said transducer mount and support serving to support said transducer mount in said opening with the lower surface of said transducer mount extending beyond the lower surface of said support whereby when the microphone assembly is placed on a user to pick up bone vibrations the transducer is yieldably urged against the user to move as the associated bones vibrate.

3. A bone conduction microphone assembly as in claim 2 wherein the upper surface of said support is above the upper surface of said transducer mount.

4. A bone conduction microphone as in claim 1 wherein said support, transducer mount and spring means are formed as a unitary molded assembly.

5. A bone conduction microphone assembly as in claim 4 wherein said spring means comprises a plurality of narrow radially extending members.

6. A bone conduction microphone assembly as in claim 1 including a mounting assembly cooperating with said support for mounting said assembly to associated head gear.

7. A bone conduction microphone assembly comprising an acceleration sensitive transducer, a transducer mount adapted to receive and hold said transducer, a support surrounding and spaced from said transducer mount, a plurality of spring means cooperating between said mount and said support to yieldably urge the transducer against the head of a user with predetermined pressure when the support rests on the head of a user, a mounting assembly including spaced mounting members secured to said support for mounting said assembly to associated head gear, and damping means sandwiched between said spaced mounting members.
