Effect of Membrane Damage on Loudspeaker Performance

This paper deals with the effect of membrane damage on loudspeaker parameters. Tweeters with small dents in their metal membranes and with a perforation in their fabric membranes were tested. Acoustic parameters of the loudspeakers were investigated by measuring the sound pressure level frequency response and vibrations of loudspeaker’s membrane. A scanning laser Doppler vibrometer was used for the latter measurements. It was found that dents and a perforation in the tweeter’s dome may change its frequency response by more than 6 dB. As a rule, dents in the dome affect the tweeter frequency response at high frequencies while a perforation in the soft fabric dome affects the tweeter response at medium frequencies.
