A cell phone’s or any other communication device’s loudspeaker is a tiny sound generator that generates sound. Mobile phones’ loudspeakers are typically used to emit sound notifications for things like alarms, incoming texts, and incoming calls.
Users have started playing music through the built-in speakers on their mobile phones since they started acting as portable music players a few years ago. Manufacturers have started adding more potent loudspeakers, or even a pair of loudspeakers, to their music- or video-focused mobile phones in recognition of this new application for the loudspeaker. This allows for precise stereo reproduction and improved spatial effects.
In order to handle calls hands-free or even have conference calls with others in the same room, loudspeakers are also used to replicate voice calls out loud (this usage of the mobile phone is termed a speakerphone, which is not to be mistaken with a loudspeaker).
Model to model variations may exist in loudspeaker implementation. For instance, some manufacturers utilise the earpiece speaker to generate sound warnings instead of a separate loudspeaker in order to save bulk and make phones slimmer.
One thing matters regardless of how you use it—loudness—whether for leisure, conference calls, or just regular ringing. Aside from the occasional subjective comment, we had thoroughly examined this in our assessments; but, in 2007 we felt it was time to adopt a more scientific stance.
We then invested in a useful piece of gear, a digital noise/loudness metre, to begin objectively measuring that crucial component of contemporary phones: the loudspeaker’s actual volume.
For the record, this is the configuration of our test system. We conduct our testing in a single, silent room, measuring sound levels with the handset loudspeaker facing the microphone at precisely one meter’s distance.
Three distinct tests are conducted. We take many measurements in succession for every test; we often pick the average of the remaining values and ignore the top and lowest results.
The following are the three tests:
1) The sound of the phone ringing. We have a vintage ringtone that sounds like an old-fashioned phone. Most phones appear to function fine when we use them.
2) Noise in the pink. We employ a pink noise sample. Our measurements with it give us a good idea of how well the handset speakers would perform while playing regular music. Undoubtedly, teenagers value a phone that lets them turn up the volume to the maximum degree.
3. A manly human voice. This is a crucial test since, whether you’re in a conference room or your automobile, volume matters a lot when using a loudspeaker for speakerphone applications.
The outcomes of every phone test that was conducted are available right here.
