Title: Speaker device
Inventor: FUJIHIRA MASAO
IPC: H04R9/02
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To limit excessive sensitivity vibrations of a vibration system and to secure good low frequency characteristic by forming an airtight space by means of a damper and a magnetic circuit part and coupling the inside and outside of the airtight space via the magnetic circuit. SOLUTION: When the drive current is supplied to a voice coil 23 and a voice coil bobbin 24 moves toward the back of a speaker device 1, a damper 26 is displaced and an airtight space 27 is compressed. At the same time, the quantity of the air flowing to the outside is limited by its narrow path 17 and the internal pressure of the space 27 temporarily increases. Accordingly, the load is applied to the bobbin 24 moving toward the back of the device 1. Meanwhile, the internal pressure of the space 27 temporarily decreases due to the extension of the space 27 when the bobbin 24 moves toward the front of the device 1. Thus, the load is applied to the bobbin 24 moving to the front of the device 1. In such a constitution, the load is applied to the movement of the bobbin 24 due to the variance of both internal and external pressure of the space 27.  As a result, the excessive sensitivity vibrations of a vibration system 20 can be limited.
