发明名称 ELECTRONIC DEVICE HAVING A MULTI-MODE ACOUSTIC SYSTEM AND METHOD FOR RADIATING SOUND WAVES.
摘要 <p>An electronic device (100) having a multi-mode acoustic system (120) and a method (500) for radiating sound waves are described herein. The acoustic system (120) generally includes a transducer (530), a first port (510), and a second port (520). The first and second ports (510, 520) may be acoustically coupled to the transducer (530). The second port (520) may be acoustically symmetric relative to the first port (510) such that output from the second port (520) is substantially identical to output from the first port (510).</p>
