Loudspeaker e.g. electromagnetic speaker, enclosure, has ports each extending along height of case and communicating with S-shaped baffle having input channel that converges so that output channel is terminated by diverging towards port |
摘要 |
<p>The enclosure has a back wall (12) whose inner curve is such that sound wave emitted in a case by a membrane of a loudspeaker and reflected by the wall does not come back along an axis of the loudspeaker. Ports (25) are constituted by a vertical oblong opening provided in an angular part (13) that connects a front wall (10) and branches (12a, 12b) of the wall (12). Each port extends along a height of the case and communicates with an S-shaped baffle (30) having an input channel (E) that converges so that an output channel (S) is terminated by diverging towards the port.</p> |
