For the loudspeaker manufacturers, the long time spending on power test required by relative standards or buyers has deeply influenced the period of product design and development. The authors apply the theory of reliability to cut the duration of loudspeaker power test. On the basis of experiment data, a model of loudspeaker life distribution is propounded, from which an accelerated factor of loudspeaker power test is derived and then the characteristic of loudspeaker under normal working conditions can be estimated. The method can be used on relative power test conveniently and shorten the duration of the test effectively.
