Title:
HEADPHONE
Document Type and Number:
Japanese Patent JPS5910093
Kind Code:
A
Abstract:

PURPOSE: To ensure hearing of a sound added with an indirect sound component, by providing a diaphragm in addition to a speaker, connecting the diaphragm to a spring and obtaining a reverberation sound from the diaphragm when a sound is produced from a speaker of a headphone.

CONSTITUTION: For a headphone, the 2nd diaphragm 4 is set beside a speaker unit 3 consisting of the 1st diaphragm 1 and a magnetic circuit 2. An end of an elastic matter, e.g., a spring 5 is connected to the diaphragm 4. In such a constitution of the headphone, the sound wave radiated from the unit 3 reaches directly the ears and at the same time vibrates the diaphragm 4. The vibrations of the diaphragm 4 repeat reflections many times via the spring 5 and are radiated again by the diaphragm in the form of a reverberation component.
