POINT EXCITATION PLACEMENT IN AN AUDIO TRANSDUCER |
摘要 |
The present invention provides methods and apparatuses for an audio transducer. The audio transducer is excited by driving a paddle of a diaphragm. A plurality of node regions of a paddle is determined for the higher-order modal components, which correspond to resonance frequencies and have an order greater than one. An intersection region of at least two higher-order modal components is identified, in which an excitation point is located with the intersection region. The diaphragm of the audio transducer includes a frame, at least one hinge, and a paddle. The paddle connects to the frame by the at least one hinge and is excited by a signal source at an excitation point to produce an acoustic signal. |
