Ear microphone utilizing vocal bone vibration and method of manufacture thereof
First Claim
1. In a displacement type bone vibration ear microphone having a support member with end faces, an electroacoustic transducer element supported in one of the end faces of the support member and extending outwardly therefrom and having an outer free end, and a damper member formed so as to enclose therewith said electroacoustic transducer element, the displacement type bone vibration ear microphone characterized by a flexible reinforcing member disposed adjacent said electroacoustic transducer element and extending outwardly from the support member and having an outer end, the outer end of said electroacoustic transducer element and the outer end of said reinforcing member being adjacent to each other, and said damper member enclosing the periphery of said electroacoustic transducer element and said reinforcing member thereby providing protection for said electroacoustic transducer element and heightening the efficiency of electroacoustic conversion.

Abstract
This invention, directed to a displacement type bone vibration ear microphone possessing an electroacoustic transducer element planted in one of the end faces of a support member and a damper member formed so as to enclose therewith the electroacoustic transducer element, is characterized by disposing a flexible reinforcing member around or near the electroacoustic transducer element, allowing a free end of the electroacoustic transducer element and a outer end of the reinforcing member to be joined or juxtaposed to each other, and enclosing the periphery of the electroacoustic transducer element and the reinforcing member with the damper member thereby providing protection for the electroacoustic transducer element and heightening the efficiency of electroacoustic conversion.

12. A method for the manufacture of a displacement type bone vibration ear microphone, characterized by comprising the steps of providing a supporting member having at least one end, supporting an electroacoustic transducer element in the one end of the supporting member, the electroacoustic transducer element having an outer end, mounting a reinforcing member for said electroacoustic transducer element in said one end of said supporting member to form an assembly, the reinforcing member having an outer end, the outer ends of said electroacoustic transducer element and said reinforcing member being adjacent to each other, inserting the outer ends of the electroacoustic transducer element and reinforcing member of the assembly into a cylindrical die, filling said cylindrical die with liquid resin for formation of a damper member until at least said electroacoustic transducer element and said reinforcing member are completely submerged thereunder, and then curing said resin.
