排气噪音的有源设计
摘要：
用于具有内燃机(6)的车辆(8)的有源噪音控制系统(9)的发声器(1)被公开。发声器(1)包括第一壳体(10)，其具有至少一个排气入口(11)和不同于所述至少一个排气入口(11)的至少一个排气出口(12)；以及根据电控信号产生噪音的至少一个电-声变换器(20)。至少一个电-声变换器(20)位于第一壳体(10)内或被直接附接到第一壳体(10)。另外，包括上述发声器(1)的有源噪音控制系统(9)和包括该有源噪音控制系统的车辆也被公开。
摘要（英）：

A sound generator (1) for an active noise control system (9) for a vehicle (8) with internal combustion engine (6) is disclosed. The sound generator (1) comprises: a first casing (10) with at least one exhaust gas inlet (11) and at least one exhaust gas outlet (12) different from the at least one exhaust gas inlet (11) and at least one electro-acoustical transducer (20) that is configured to produce sound in dependence on an electrical control signal. The at least one electro-acoustical transducer (20) is located within the first casing (10) or directly attached to the first casing (10). Furthermore, an active noise control system (9) comprising the above sound generator 1 and a vehicle comprising the active noise control system are disclosed.
