If you are referring to a capacitor that connects to a 'tweeter' (the smaller high frequency speaker) it's function is to filter out the lower (bass) frequency signals, a capacitor 'blocks' direct currents (DC) and as a result the electrical 'signal' to a loudspeaker gets 'closer' to a direct current, the lower the frequency, so the capacitor is 'happy' to let high frequency (treble) signals pass through it, but resists the signal as the sound frequency decreases, down to the lower (bass) signals.

the capacitor and its associated resistor set the time constant.
To connect it to the circuit.
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
The function that describes the current through a capacitor as a function of time is given by the equation I(t) C dV/dt, where I(t) is the current at time t, C is the capacitance of the capacitor, and dV/dt is the rate of change of voltage with respect to time.
A fixed capacitor has a fixed capacitance (within certain limits influenced by aging). So it can fulfill any function that a (variable) capacitor fulfills, beside changing its capacitance easily (e. g. by turning a wheel).
The function of the speaker it to talk about the topic for which s/he was engaged, or to the common interest of the group. If you mean an electronic device , a speaker is to amplify sound.

In electronic circuits a capacitor is used to pass AC and block DC.

The two factors that determine the capacitive reactance of a capacitor are the frequency of the AC voltage applied to the capacitor and the capacitance value of the capacitor. At higher frequencies and with larger capacitance values, the capacitive reactance decreases.
