摘要： A composite speaker is provided capable of obtaining larger sound output than that of a conventional flat panel speaker and flat speaker when input with an audio signal of the same strength. The composite speaker includes: one magnet or a plurality of magnets disposed at predetermined intervals to each other; a yoke for forming a magnetic circuit with a magnetic gap to the magnets; a voice coil disposed in a gap between the magnets and the yoke so as to interlink with the magnetic circuit; a diaphragm with the voice coil fixed to one face thereof; a frame that supports the diaphragm at peripheral edge portions of the diaphragm and houses the magnets and the yoke; a speaker base plate fixed to the frame at the side of the frame supporting the diaphragm or at the side of the frame opposite to the side supporting the diaphragm; and a phase rotation member configured by an elastic member provided between the speaker base plate and the yoke; wherein sound is generated from both the diaphragm and the speaker base plate.

摘要： A flat acoustic transducer (100) includes a permanent magnet (10) and a magnetic member (20), which are arranged adjacent to each other with a predetermined interval, a flat vibrating membrane (30), provided facing the permanent magnet (10) and the magnetic member (20), and at least one coil (40), fixed to the vibrating membrane (30). In the flat acoustic transducer (100), an electrical signal is applied to the coil (40), to obtain vibration force (F) on the vibrating membrane (30) by way of a magnetic flux Φ generated between a magnetic pole face (12) of the permanent magnet (10) and the magnetic member (20), a step (50) is provided between the magnetic pole face (12) and the upper face (22) of the magnetic member (20), while at least part of a winding (42) of the coil (40) at the time of no application of an electrical signal is arranged inside the step (50).
