Wired microphone 3.5mm

A “wired 3.5 mm microphone” is a microphone that connects to a device (phone, laptop, PC, camera, etc.) using a standard 3.5 millimeter audio jack (also called a “3.5 mm plug

• <p class="ql-align-center"> <strong>Spec / Parameter</strong></p><p class="ql-align-center"> <strong>What it means / Typical Range / Notes</strong></p><p> Connector / Output</p><p> 3.5 mm jack (TRS or TRRS) — the physical plug that connects to PC, phone, camera etc.</p><p> Microphone type / Element</p><p> Often electret condenser (common for small 3.5 mm mics) or sometimes dynamic. Condenser mics tend to be more sensitive. &nbsp;</p><p> Polar / Pickup Pattern</p><p> Can be omnidirectional (picks up sound from all around) or cardioid / unidirectional (picks up mostly from front) — affects what sound you capture. &nbsp;</p><p> Frequency Response</p><p> Typical range: ~ 20 Hz – 20 000 Hz (some mics a bit narrower). This defines which frequencies (low bass to high treble) the mic can capture. &nbsp;</p><p> Sensitivity</p><p> Usually given in dBV/Pa (or mV/Pa). A typical value for 3.5mm condenser mics might be around −40 dBV/Pa, or similar. Lower (more negative) values = less sensitive. &nbsp;</p><p> Signal‑to‑Noise Ratio (SNR)</p><p> Indicates how much louder the desired sound (your voice) is compared to the mic’s self‑noise. Higher is better. Good mics often have SNR ≥ ~65–80 dB. &nbsp;</p><p> Maximum SPL (Sound Pressure Level)</p><p> The loudest sound the mic can handle without distortion. For decent condenser mics: often 110 – 140 dB SPL or more. &nbsp;</p><p> Output Impedance</p><p> Typical values might be in the hundreds to a few kilo-ohms (e.g. 150 Ω, 470 Ω, or up to ~2.2 kΩ depending on design). Lower impedance tends to be more compatible with many inputs. &nbsp;</p><p> Cable Length (if wired)</p><p> Usually around 1.5 m – 2.5 m for small 3.5 mm mics, enough for general PC / camera use. &nbsp;</p><p> Power Requirement</p><p> Most 3.5 mm “plug‑in” condenser mics draw a small voltage (plug‑in power, often a few volts) from the host device. &nbsp;</p><p> </p>
