Yang Ding-jun · Audio Engineering · 2009
Traditionally,technical requirements for loudspeakers used in electronics products which are for instance as TV sets and audio recorders are understood well by every one.Especially there are a lot of mature technical standards to guide so that it seems no doubts exist at all.But it becomes complicated these years in China because of market and RD reasons.A lot of loudspeakers need to supply to different countries.Therefore it is possible for Chinese manufacturers to meet different standards and technical requirements from different customers.Some basic questions,which are sine wave listening,power matching between loudspeaker and amplifier and so on become doubtful from tradition.Also there is a trend to demand loudspeaker with some technical specification beyond physics limitation.The suppliers often meet dilemma because of management reason.The positive and scientific discussion for related issues based on some observing and thinking is promoted.
