Title:
ELECTROMECHANICAL TRANSDUCER AND ELECTROACOUSTIC TRANSDUCER
Document Type and Number:
Japanese Patent JP2019193218
Kind Code:
A
Abstract:
To provide an electromechanical transducer, etc., that suppresses inclination relative to the center shaft of an armature and which is suitable for improving performance and reducing the size.SOLUTION: The electromechanical transducer comprises: a structure part in which a magnet (15), yokes (10, 11) and a coil (12) are integrally arranged; an armature (13) having an inside part penetrating the inside space of the structure part along the center shaft (13c) in a direction X and outside parts on both sides thereof, the armature constituting a magnetic circuit with the structure part and displacing in a direction Z; and elastic members (14) for adding resilience to the armature. A first engaging part (E1) and a second engaging part (E2) are formed in each elastic member, the width where a force in the direction Z acts between each elastic member and the structure part via the first engaging part having a first distance (2b), the width where a force in the direction Z acts between each elastic member and the outside parts via the second engaging part having a second distance (2a), both being set to the dimension condition 2a>2×2b.SELECTED DRAWING: Figure 10
