Appl. No.:

16/817006

International Classification:

H04R 7/24

H04R 7/04

Abstract:

An electro-acoustic driver includes a diaphragm formed of a compliant material, a bobbin configured to hold a winding of an electrical conductor and a housing having a housing axis that is substantially coaxial with the bobbin. The diaphragm is fixed to one end of the housing and a stiffening element is fixed to an inner region of a surface of the diaphragm. A motion of the bobbin along a bobbin axis generates a movement of the inner region of the diaphragm to thereby generate an acoustic signal that propagates from the diaphragm.

Abstract:

An electro-acoustic driver includes a diaphragm formed of a compliant material, a bobbin configured to hold a winding of an electrical conductor and a housing having a housing axis that is substantially coaxial with the bobbin. The diaphragm is fixed to one end of the housing and has a substantially planar shape when the diaphragm is at rest. A stiffening element is fixed to an inner region of a surface of the diaphragm. A motion of the bobbin along a bobbin axis generates a movement of the inner region of the diaphragm to thereby generate an acoustic signal that propagates from the diaphragm.

Inventors:

- Framingham MA, US
Christopher A. Pare - Franklin MA, US
Lei Cheng - Wellesley MA, US
Nicholas John Joseph - Boston MA, US
Benjamin G. K. Peterson - West Boylston MA, US

International Classification:

H04R 1/10
H04R 3/04

Abstract:

An electro-acoustic transducer is provided that comprises a diaphragm and a magnet assembly comprising a magnet and a back plate. The back plate comprises at least one first vent. The diaphragm generates sound during a movement of the diaphragm relative to the back plate. The transducer further comprises a printed circuit board comprising at least one second vent and a cavity between the printed circuit board and the back plate that separates the at least one first vent from the at least one second vent.
