There were also reports of device instability from some users on iPhone 6 and iPhone 6S models, including situations where the device would unexpectedly shut down once its battery capacity reached 30% (with one user having described the battery percentage as unexpectedly jumping down to 1% before doing so, but still appearing as 30% after the ...
In audio systems, parasitic oscillations can sometimes be heard as annoying sounds in the speakers or earphones. The oscillations waste power and may cause undesirable heating. For example, an audio power amplifier that goes into parasitic oscillation may generate enough power to damage connected speakers. A circuit that is oscillating will not ...
Violent, triggering or sexual content isn’t your best choice to listen to out loud. When exercising outside, it can also be a safety issue to use your phone’s speakers and not headphones (and ...
The braking effect is critical to speaker design, in that designers leverage it to ensure the speaker stops making sound quickly and that the coil is in position to reproduce the next sound. The electrical signal generated by the coil travels back along the speaker cable to the amplifier.
A speaker 3 dB more sensitive than another produces double the sound power (is 3 dB louder) for the same electrical power input. Thus, a 100 W driver (A) rated at 92 dB for 1 W @ 1 m sensitivity puts out twice as much acoustic power as a 200 W driver (B) rated at 89 dB for 1 W @ 1 m when both are driven with 100 W of electrical power.
Apple is blaming a software bug and other issues tied to popular apps such as Instagram and Uber for causing its recently released iPhone 15 models to heat up and spark complaints about becoming ...

A noise-cancellation speaker emits a sound wave with the same amplitude but with an inverted phase (also known as antiphase) relative to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out – an effect which is called destructive interference.
