    Questions on Loudspeaker Diaphragm Movement

    Thanks i understand. Is an audio signal always sinusoidal or there are flat turns or edges? If it is not sinusoidal, how can I predict its displacement for a particular time?

    Questions on Loudspeaker Diaphragm Movement

    ok. But what I mean is what is the cone's movement,example, per 1 millisecond. Such that per millisecond there is a varying frequency and loudness. What I am looking for is a some kind of graph or line graph showing the cone's movement with varying frequency and loudness for certain time...

    Questions on Loudspeaker Diaphragm Movement

    Thanks berkeman. But if a speaker vibrates and moves very fast, how would I be able to measure the displacement of the cone with regards to a specific frequency and volume? Do you know where I can find a data of speaker movement for any speaker? Thanks Ü

    Questions on Loudspeaker Diaphragm Movement

    thanks for the reply. I don't have the instruments to measure the speaker's movement that is why I am looking for a data regarding that. Perhaps a loudspeaker manufacturing company can provide me one. Do you know a company that may give me such data that i need? thanks

    Questions on Loudspeaker Diaphragm Movement

    Good day to all! I just want to ask if someone here knows some data or measurement of speaker diaphragm movement(distance moved by the diaphragm relative to its resting position) of any speaker(any type or brand) when a certain frequency and volume is applied to it. I just badly need the...

    Speaker Questions

    Good day to all. I have some questions regarding speaker specifications: 1. What does RATED POWER of the speaker mean? 2. Why is the impedance of the speaker usually has a value of 4 ohms, 16 ohms etc, when speakers also contain inductors and capacitors in their drivers? 3. What is the...

    I'm not sure if my answer is correct, I need someone to help me solve this so I could check my answer.. 1.) 2 coils A and B are magnetically coupled. When connected in parallel-aiding, the total inductance is 2.33 H, and when connected in parallel-opposing the total inductance is 1.4H. The...

    Intro to Elec node analysis help

    using nodal analysis, i arrived with 2 equations: -(V2-V1)/100 - (V2-V3)/220 - V2/3900 = 0 <equation1> -(V3-V2)/220 - V3/1000 - V3/1200 = 0 <equation2> also: V1 = 5 <equation3> since the 3 equations...

    Plz help me in solving this circuit

    So did you get the answer? Using “Mesh Analysis” I arrived with 2 equations -6i2 - 2Ri2 + (9/2)R + 3 = 0 2Ri2 - (9/2)R + 6 + 2i2 = 0 You can easily solve R or i2 using a calculator. But I’m not sure if my equations are right because im so0o0ooo so0o0o0 sleEeEEeEEeeEpppyyyy :zzz...
