Abstract
An electro-acoustic transducer having a chassis with a plastic contact surface for attachment of a vibratory diaphragm. The diaphragm is attached by an ultrasonic weld between the contact surface on the chassis and the edge of the vibratory part.
Claims6
An electro-acoustic tranducer comprising a chassis having a contact surface, and a vibratory diaphragm having an edge, wherein said contact surface is formed of a plastic material, and said vibratory diaphragm is attached to the contact surface by an ultrasonic weld.
A method of manufacturing an electro-magnetic transducer having a chassis with a contact surface, and a vibratory diaphragm with an edge attached to the chassis, at least the contact surface consisting of a plastic material, comprising the steps of:
- placing a diaphragm onto a chassis with the diaphragm edge against a plastic contact surface of the chassis, and
- pressing the radiating surface of an ultrasonic generator against the edge of the diaphragm so as to weld the edge to the plastic.
