The op-amp output is connected to the center of diode-resistor biasing circuitry, and this signal manipulate the biasing point. At idle condition, when there is no signal in the input, the output should be bet at Vcc/2.

The input of the opamp should be at half the supply voltage which is ground with a dual polarity supply. If you use a single polarity supply then use two resistors and a filter capacitor to make a voltage divider that provides half the supply voltage. The output will also be at half the supply voltage so a coupling capacitor must feed the speaker.
Audio Designs With Opamps

When an opamp is operated in its linear mode (which is most of the time for audio and most other amplification circuits), the negative feedback circuit will cause a voltage to appear on the inverting input (-in) that is ( almost) exactly equal to that present on the non-inverting input (+in).

speakers have a low impedance, typically 8-Ohm. Even for a low-power 0.5W audio amplifier, PIR 2 /2 requires that the amplifier must be able to source a peak AC current of around 350 mA with an 8-Ohm load. This is a lot more than a typical op-amp is designed to provide. For example, the LM358 and LF353 (two op-amps used in this lab) can source

The proposed op amp MIC preamplifier circuit consists of a couple of stages, which includes IC1 as the non-inverting amplifier. and IC2 as an inverting amplifier. Each amplifiers are commonly available types. IC1's closed loop gain is fixed at around 45 times through a negative feedback circuit built using the R3 and R5 network.
