The electro-mechanical resonances strongly affect the current that must be supplied, in order to maintain a flat (controlled) output voltage over the specified frequency range. For example, the current in the voice-coil reaches a null at time 0.1 seconds, which corresponds to the effective "spring-mass" resonance frequency (60 Hz). The loudspeaker reaches its minimum impedance around 600 Hz, or at 0.6 seconds where the peak load current is observed.</p> <p>The simulation results also show that the average power (q1/npn/pwr_avg) in the BDP947 BJT exceeds its 5 Watt rating across the entire range, but especially at lower frequencies. The red "hot part monitor", with the junction to ambient thermal resistance set to 10 C/Watt, as given in the datasheet, shows the part temperature rising to over 100 C. These diagnostic indicators make it obvious that we need a bigger transistor!</p> <p>All of the parameters in blue can be changed by the user and a new simulation run. The updated scope waveform results will show the effect of that change. You can change the electrical resistance and inductance of the voice-coil, as well as the speaker cone mass and linear spring rate that affect the resonance frequency.</p> <p>* Note: Please refer to this companion example, that shows the input impedance frequency response of the loudspeaker alone:</p> <p>https://www.systemvision.com/design/loudspeaker-only-frequency-response</p> About text formats Tags LoudspeakerAmplifierelectro-mechanical resonanceBDP947NCV20071 Op-AmpBDP947 NPN TransistorMechatronicsmagnetic actuator Select a tag from the list or create your own.Drag to re-order taxonomy terms.
