4s speakers

4s speakers

Confirmed with Apple. There is one speaker the other speaker at the top does not play music it is only a receiver. Plays calls and works with Siri.

Someone at Apple doesn't know what they are talking about. I just tested ringtones and YouTube. Came out the bottom right and the top center ear piece. Clear as daye. Tested with my iPhone 4S.
 
Well then your phone is special or maybe you should be the tech support at Apple since your more knowledgable. I have tested mine as well and nothing happens. Everyone I know says the same thing & the actual iPhone user manual obviously isn't correct either.
 
I am inclined to agree that manual is wrong and that the Tech Support at Apple may not know the correct information because the manual is wrong.
 
Decided to download the iPhone pdf manual and search it. Only nine instances of the word speaker and two instances of the word speakers are in it. Not one of the references says that sound only plays thru the bottom right speaker.

Guess the manual doesn't clearly state that sound only comes out of just one area.
 
Here is a picture. The diagram shows 1 speaker.

Ok you realize that the receiver is a speaker? I'll see if I can find a decibel meter to close this mystery.
 
I understand that but it doesn't play music or You Tube videos as you claim. It is for calls and you can change the setting on Siri to work when you put it up to your ear. The iPhone has 1 speaker. As included in the picture from the manual and this from Apple's website. Just admit you were wrong it is ok to be incorrect sometimes! The Apple manual and website are correct. Enjoy listening to your music and videos from your 1 speaker located in the lower right hand corner.

LOL. Will get a decibel meter and see what is physically happening. But fair warning, I only need one hand to count how many times I have been wrong when it comes to Android and iOS devices. And I still have fingers left to use up :D
 
Exactly! Let's have fun, test and discuss the results. We all might learn something. Which in my book is always a really good thing.

My iPhone does the same exact thing yours does Skull One!
A ringtone will even blare in my ear while on a phone call. Quite annoying! :D
 
Anyone get any official results? I am using MLB at Bat 2012 right now listening to the Rockies game and saw this thread and for sure there is sound coming out of the bottom speaker and the receiver speaker. The bottom speaker is louder, if you cover it up it seems like the sound goes away but if you put it closer to your ear it you can hear the sound coming from the ear speaker.
 
After an hour of trying to make this test a clean as possible and reproduce-able, I found a way. :D

Lets get the funny and fun stuff out of the way before I reveal the testing and results.

Note to self: Take the Otterbox Case off the phone once a week and clean the iPhone 4S. What I found after probably 3 months of it being on was NOT pretty. LOL!

Never want to hear the lyrics "Am I better off dead. Am I better off a quitter" again.


Now for the thank yous.

First I want to thank 1WaySTREET for being a total gentleman (or lady) during this lively discussion. This is how discussions should be done. Respectful with as much factual data as possible. 1WaySTREET made me think. And that is how we learn.

Second I want to thank Apple's engineers for the iPad (3rd Gen). Without their mic design, this verifiable and repeatable testing would not have been possible.

Third I want to thank Fossil Software for writing App Store - AppZilla 2 - 120 in 1!. Their software has a built in decibel meter that was perfect for this testing.

I started with the following devices in front of me: iPhone 4S, iPhone 4, iPad (3rd Gen) and Droid X.

The first thing to do was find a mic that was not only consistent but could discriminant between a direct sound and a ambient/reflective sound. After an hour of testing the iPad (3rd gen) was the winner hands down. It could tell when I held the bottom of the iPhone, on volume level 1, between the left side (iPhone 4S mic) and the right side (Speaker). This was critical to remove any possibility of detecting sound that was bleeding from the speaker to other parts of the phone. Once I was 100% positive that the iPad mic, with the iPhone at that low of a level, was fit for the job I began my testing.

I ran three levels of tests using iTunes playing the song Nothing by The Script.

1st: At level 3 on the volume.
2nd: At level 8 with my finger covering the bottom right speaker. (Yes there is a good reason)
3rd: At level 8 without my finger covering the bottom right speaker.

The iPad was put on my computer desk with a book under it so that I could make sure the mic was isolated from vibrations and could be set out far enough so that I could hold all three testing points of the phone up to it without making contact. The decibel meter read a very steady 40.3 dB to 40.4 dB average with a peak of 40.9 dB.

1st test was done with my ear and then the iPad.

Ear (Subjective): Speaker - 10, Mic - 7, Receiver - 3.
iPad (Factual): Speaker - peak 98 dB, Mic - peak 44.7 dB, Receiver - peak 42.9 dB.

This test is the most conclusive that Receiver is NOT directly moving air. Which means that 1WaySTREET and Apple's documentation are correct and I was wrong. I did get one consolation prize out of this; I have really good hearing. After looking at some tear downs of the iPhone 4S, I can see areas that can be reflective sound channels.

The 2nd and 3rd test was to find out just how much air movement was actually being reflected so that the iPad mic would pick it up.

Ear (Subjective):
Uncovered; Speaker - 10, Mic - 8, Receiver - 7.
Covered; Speaker - 7, Mic - 9, Receiver - 8.

iPad (Factual):
Uncovered: Speaker - peak 100 db (maxed out), Mic - peak 70.3 dB, Receiver - peak 47.8 dB.
Covered: Speaker - peak 79.9 db, Mic - peak 80.9 dB, Receiver - peak 51.9 dB.

There you have it. If you own an iPad (3rd gen), iPhone 4S and buy AppZilla 2 you can reproduce what I have done here tonight.




And so 1WaySTREET has something to frame ;)

I was wrong.



Note to self: I think I only have one finger left to use up my first hand. Better be more careful. BWAHAHAHAHAHA
 
Awesome test results Skull One. :)
This was a great discussion and I'm glad you got to the bottom of it!
This discussion is a great example of how discussions should work. Friendly and factual!

Gotta love this Community. :)!!
