Commentary
This is a speaker actuator unit that uses a diaphragm attached to a wall or desk.
In order to obtain sufficient driving force, a strontium magnet is used for the magnetic circuit.
In addition, a magnetic shielding structure using a cancel magnet is adopted to cope with leakage magnetic flux.
In addition to the high input resistance of 50W maximum input, the built-in limiter element protects the unit from excessive input to cope with unexpected excessive input.
Oxygen-free copper (OFC) superfine wires are used for the attached lead wires, and the jacket material is made of soft materials with less squeal.
It is a drip-proof design (JIS) to realize versatile setting free, and can be used in kitchens and outdoors.
