This Audio Product Education Institute Workshop is targeted at product Development Organizations who develop and sell loudspeaker systems and transducers.

Every product that reproduces speech and/or music will have sound eventually be played out of a loudspeaker transducer. As this is the final stage before the sound reaches the listener’s ear, a poor audio experience is often blamed on the loudspeaker itself. However, there are many reasons why sound quality can be poor but yet the loudspeaker itself is an exceptional design. Bluetooth devices can have bugs with their Bluetooth stack, amplifiers may be underpowered, equalization, especially when using DSP, can be too excessive thereby exacerbating a loudspeaker transducer’s non-linearities.

This presentation will focus on the audio signal chain prior to the voice coil where audio degradation can occur thereby making the loudspeaker itself sound marginal-to-poor. Several examples will be presented where one or more portions of the audio signal chain degraded audio quality but yet the transducer designer had no awareness, let alone any control, of how there signal blocks were designed. Attendees will learn what questions to ask of those engineers (or vendors) responsible for these audio signal blocks that can ultimately make or break the success of a loudspeaker-based product.
