10:30 - 11:30 Designing Transducers for Compact Active Speakers, Peter Larsen, LOUDSOFT
The LOUDSOFT FINE software suite for Loudspeaker Design and Test & Measurement is a circle of design tools, where each component supports the other. With these powerful FINE programs you can design all parts of the speaker system. The FINE R+D analysis/measurement system and the FINE QC control system supplement the design software. The Rub & Buzz function is the best on the market finding 100% failures of both active USB speakers and micro speakers. These tools are rapid and effective in modern transducer and speaker system development and the simulations very closely matches measurements of the devices when built.
11:30 - 12:30 Optimizing Compact Loudspeaker Performance—The Role of DSP, John Richards, Oxford Digital
The form factor of all consumer devices from cell phones to flat panel TVs is shrinking and often the design is under the control of a stylist rather than anyone who understands acoustics. This, together with pressure on the Bill of Materials cost and increasing customer expectations, creates real challenges in obtaining good, differentiating audio quality in the product. DSP can mitigate many of the inherent deficiencies present. The tutorial shows how a combination of an integrated suite of audio effects together with automated frequency correction can be used to radically improve sound quality whilst providing rapid time to market.
