Hosiden Has Developed Small-Sized 'Three-Magnet-Type Micro Speaker Unit' Which Has Secured Low Frequency Range
Hosiden has developed 'Three-Magnet-Type Micro Speaker Unit', which has been downsized to about 60% of our conventional products, while maintaining the same level of performance. As a three-layer structure has been adopted on the diaphragm, it is possible to acquire a low fo (the lowest resonance frequency) even if the back volume with this product is small. We have also mounted three magnets into the magnetic circuit to secure sound pressure.
Typical Features
Downsizing to about 60% of our conventional products, while maintaining the same level of performance.
The lowest resonance frequency is 830Hz. (when the back volume is 1cc)
Protection grade is IPX5 and IPX7.
With the adoption of three magnets, we have secured higher sound pressure than micro speaker units of the same size.
As this product is small-sized and has secured low frequency range, it can be used as a receiver unit, too.
