Abstract (en)
[origin: GB2408405A] A sonic emitter comprises a transducer 4, eg a micro-speaker, in a housing. The transducer has an emission surface facing a frontal resonant cavity 7, 8 and an opposed surface facing a rear resonant cavity 6. An acoustic conduit 9 links the transducer 4 to a sound outlet S2. The emitter may be incorporated in a pendant or other fashion-related article, or a mobile phone, digital camera, portable games console or hand-held computer. The conduit 9 may be flared and the cavities may contain acoustic damping material.
