Electromagnetic transducer

An electromagnetic transducer, comprising:

• a frame;
• a vibrating unit including a diaphragm and a voice coil;
• a magnetic circuit unit receiving in the frame;
• a pair of elastic members connected with the vibrating unit and separated from each other, each of elastic members including a first arm attached to the diaphragm and at least a pair of second arms extending outwards from the first arm and partially attached to the frame, respectively;
• wherein each of the second arms has a first part, a stress-relieving portion connected to the first part and protruding outwards from a plane where the first part is disposed, and a second part connected with the stress-relieving portion and the first arm;
• and
• wherein the first parts are coplanar with respect to the second parts.

An electromagnetic transducer, comprising:

• a frame;
• a magnetic circuit part accommodated in the frame and including a pair of magnetic gaps;
• a vibrating unit including a diaphragm attached to the frame and a pair of voice coils partially inserted into the magnetic gaps for driving the diaphragm;
• an elastic member including a first arm attached to the diaphragm and at least two pairs of second arms extending outwards from the first arm and partially attached to the frame, respectively;
• wherein each of the second arms has a first part, a stress-relieving portion connected to the first part and protruding outwards from a plane where the first part is disposed in, and a second part connected with the stress-relieving portion and the first arm;
• and
• wherein the first parts are coplanar with respect to the second parts.
