How to access built-in speaker to listen to podcasts, music, etc, with others?

Hi Edward M. Baum,

welcome to the Apple (user-to-user) Community.

Re: "How to access built-in speaker to listen to podcasts, music, etc, with others?

What is the best way to access the built-in speaker (iPhone 12 mini) for group listening?"

The best way with group-listening would likely be to use the iPhone with a wireless speaker

Use Siri to play music and podcasts - Apple Support

Play audio from iPhone on HomePod and other wireless speakers - Apple Support

How to pair iPhone with a non-Apple bluetooth speaker:

Else:

Wondering if this Apple Support article can help : ie: switch to the speaker:

While on a call on iPhone - Apple Support

Eg: says

"When you’re on a phone call, you can switch the audio to the speaker or a Bluetooth device.

"Tap the audio button, then choose an audio destination".

Clearer sound ?

You might want to check the speaker grill for any obstructions or see if it needs cleaning

and

What to do: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

All the best :-)
