Impeccable technically and charmingly visually, iPhone-4 lost the leading position in the popularity rating to its fellow iPhone-4s. But they still have a lot in common.
When is iPhone-4 speaker replacement necessary?
The sound emanating from the polyphonic speaker of the phone sometimes loses its juiciness and ability to give pleasure a pleasant tonal sound. Water, mechanical damage, and even frequent use of the phone as a player at the maximum volume level are to blame. Of course, factory defects should not be discounted, despite Apple's impeccable reputation. Replacing the dynamics of the iPhone in this case is an inevitable process, which after reading the article will become understandable and elementary to you.
Where can I get a speaker for a hoarse iPhone?
Today, this issue is resolved quite easily. In almost every city there are
specialized stores engaged in the sale of components for mobile phones. In the absence of such, you can resort to the help of a mobile phone repair workshop in which replacing the iPhone-4 speaker is a normal work operation. This fact simply obliges the workshop to have the required component available. Most likely, you will not be denied the sale of much-needed parts. The only difficulty can arise only if you do not sell the original speaker, but a copy of a third-party manufacturer, which can significantly affect the quality of the reproduced sound and, of course, the durability of the work. Usually a copy is much cheaper than the original.
We prepare the place and the working tool
The place where the iPhone-4 speaker will be replaced must be selected as convenient as possible. You should not be located in the aisle or near the doors, as at the most crucial moment you may be prevented or accidentally pushed. The surface of the table should be flat and without unnecessary objects, and the lighting should be sufficient so as not to strain your eyesight. Of the tools you will need: Phillips and iPhone-pentalobe (star) screwdrivers, tweezers and a plastic spatula. The last element is only desirable, since it can be replaced by a regular plastic card (it is needed to disconnect the cable connectors and protective shields).
Step-by-step instruction: direct replacement process
Replacing the speaker iPhone-4 is carried out in stages. All dismantling operations are described when the phone is facing down.
- At the bottom of the phone, unscrew the two bolts and remove the back cover.
- Disconnect the battery connector cable, located under the protective screen.
- Remove the protective screen from the bottom loop connector (near the removed battery cable).
- Disconnect the bottom cable from the system board.
It should be noted that the iPhone-4s repair associated with the replacement of the polyphonic speaker would be complete at this stage, since the polyphonic unit can be replaced with 4s without removing the motherboard. Let's continue.
- We turn off and remove the upper protective screen, the upper left corner.
- We remove the camera and snap off all the cables of the top of the phone.
- We take out the SIM-tray and dismantle the system board, which is mounted on four screws.
- We unscrew and remove the polyphony block, having previously disconnected the coaxial cable - a plastic module with two bolts. This is the polyphonic speaker.
- We install a new speaker, that is, a polyphony block, and with special attention we collect the phone.
Finally
Attention is first of all! Do not be distracted, you need to finish the job. Do not rush, you will surely succeed. Remember that the screws and parts remaining after assembling the phone on the table cannot be superfluous. Everything should be in place!
