Loudspeaker – definition


A mobile phone or other communication device’s loudspeaker is a tiny sound driver that is installed within the device and utilised to generate sound. Historically, sound warnings for events like incoming calls, incoming texts, and alarms have been produced by loudspeakers on mobile phones.

Users have started listening to music on their mobile phones’ built-in speakers as a result of their becoming portable music players in recent years. Manufacturers are starting to outfit their music- or video-focused mobiles with more potent loudspeakers, or even a pair of loudspeakers, enabling perfect stereo reproduction and improved spatial effects as a result of this new sort of usage for the mobile phone loudspeaker.

Moreover, loudspeakers are utilised to amplify voice calls, enabling users to conduct calls hands-free or even have conference calls with other people in the same space (that use of the mobile phone is called a speakerphone, which is not to be confused with a loudspeaker).

The way loudspeakers are implemented might differ between models. For instance, some manufacturers opt not to employ a separate loudspeaker and instead use the earpiece speaker to emit sound warnings in order to conserve space and make phones slimmer.

There is just one thing that matters, regardless of whether you use it for entertainment, conferences, or just for ringing: volume. In addition to the casual subjective comment, we had gone into great detail about this in our assessments, but in 2007 we thought it was time to adopt a more methodical approach.

Thus, in order to begin measuring objectively that crucial component of current phones—how loud the loudspeaker actually is—we acquired a handy piece of equipment called a digital noise/loudness metre.

This is a record of how our test setup works. We conduct our testing in a single, silent room while recording the sound levels with the handset speaker facing the microphone exactly 1 m away.

We carry out three distinct tests. We take multiple successive measurements for each test; typically, we ignore the highest and lowest values and use the average of the remaining data to get the result.


  • 1) A ringing telephone. We employ a vintage ringtone that sounds like an ancient phone would ring. Most phones seem to function fine when we use them.
  • 2) Pink noise. We make use of a pink noise sample. Our results show how well the handset speakers would perform when playing common music. Teens undoubtedly value a phone that allows them to turn up the volume all the way.
  • 3) Male human voice. This is a crucial test since volume matters a lot if you frequently use the loudspeaker as a speakerphone, whether you’re in a conference room or your automobile.
