Patent abstract
A speaker module for a personal communication device includes two transducers for generating sound on the basis of an electrical signal. One transducer outputs sound to the surroundings from a sound output thereof and the other transducer outputs sound to the surroundings via the first transducer. In this manner, two transducers require only one sound output. The sound from the second transducer may be transmitted through and filtered by an opening in a diaphragm of the first transducer. Filtering elements may be provided between the two transducers.
