Usually, the videos captured on the iPhone’s camera are of much better quality but occasionally the audio quality becomes poor due to the microphone. External microphones are very effective for getting quality audio with video.
So how to connect external microphone to iPhone?
You must have Wireless Bluetooth to connect Extra My to an iPhone. Or anyone connector such as a headboard or charger port. And these devices may require drivers or software to connect to your iPhone.
Now you may think you don’t know how to connect an external microphone? So for your convenience, I will give you some ways or guides, you can connect an external microphone to your iPhone.
How An External Microphone Will Connect To Your iPhone
Connecting an external microphone to your iPhone will not cause any problems with your phone’s internal microphone. It will only be used to maintain audio quality. I’ll tell you step-by-step how to connect an external microphone to your iPhone.
But yes, first of all you need to know that iPhone works with digital devices and digital audio like computer. However, whether the microphone is internal or external, it always produces Analog signals. Any information on the iPhone needs to be converted to Analog to digital in order to be properly placed and transmitted. Some devices are used to convert to analog-digital.
Indirectly, TRRS headphone jack or Bluetooth chips are used as external microphones in the devices. Again some devices can be used directly by connecting to the phone’s charging port.
Since iPhones work with digital audio, we need an external microphone. So I will tell you in detail how to connect the external microphones.
Connect The External Microphone Via Bluetooth
Bluetooth microphones have become very popular since many years ago. As Bluetooth connection is common, iPhone comes with Bluetooth device feature. Bluetooth is a wireless data protocol which transfers data and signals over short distances. It uses short-wavelength UHF radio waves (in the range of 2.400 to 2.445 GHz) to transmit it.
The Bluetooth mic is like any other wireless microphone and transmits signals. The Bluetooth device has a transmitter and a receiver. Transmits signals and data inside a Bluetooth microphone or connected to a microphone. A chip is found in a Bluetooth device or a receiver that acts as a receiver.
You can easily connect a Bluetooth mic to your iPhone. For that you have to follow some steps.
The first step is to turn on the transmitter of the Bluetooth device or Bluetooth microphone. Then the second step is to turn on the Bluetooth on your iPhone. If your Bluetooth device is next to your phone, it will show the name of your Bluetooth device in your iPhone’s Bluetooth list.
Then to connect the Bluetooth device to your iPhone, click on the name of your microphone shown in the Bluetooth list. After connecting Bluetooth, Bluetooth microphone will be connected to your iPhone.
If your microphone is designed using Bluetooth technology, it will connect a Bluetooth microphone.
And if the wired mic allows wireless transmission via Bluetooth, then Bluetooth will connect to the microphone transmitter.
Connect Directly Via The TRRS Headphone Jack
I think the easiest and clearest way is to connect an external microphone using the jack on the iPhone. The headphone jack will give the output signal when the microphone will give the input signal.
The iPhone’s headphone jacks are 3.5mm (1/8 ″) TRRS (tip-ring-ring-sleeve) specifically designed as a phone connection.
The TRRS is usually wired as a CTIA as a connection to the headphone jacks. Apple, the company in the iPhone brand, holds the highest position in the development of CTIA standards.
You may wonder how to configure the CTIA standard TRRS connection. I will help you to tell that.
The tip should be used for left side audio. The ring is used for the audio on the right side and also for the ground. And the sleeve is used for the microphone.
The TRRS device is designed to be used on the iPhone following the CTIA standard.
Needless to say, if you want to connect a microphone to your iPhone’s headphone jack, you’ll need a 3.5mm (1/8 ″) TRRS male phone connector.
Connecting Wirelessly Via TRRS Headphone Jack
The iPhone will be able to connect to a wireless external microphone without a Bluetooth connection. The wireless microphone can connect directly to the iPhone’s headphone jack or charger port. Wireless systems work just like Bluetooth systems. Wireless systems provide radio waves to transmit audio information.
A microphone transmitter translates audio information to a radio signal using a specific frequency. The transmitter transmits radio waves wirelessly to find its receiver. After the receiver is connected to the transmitter, the receiver receives the audio signal, delivers the output and decodes the radio signal.
So when the receiver connects the iPhone to the TRRS headphone jack, you can use any microphone successfully on your iPhone.
Connect Via Charging Port
There are some microphones that can be connected via the iPhone’s charging There are some microphones that can be connected via the iPhone’s charging port. These are commonly known as USB microphones. The use of USB microphones in computers has made them very popular. Moreover, this microphone is very effective. The microphone can be used on the iPhone in the same way that it is used on a computer.
After connecting the microphone to the iPhone’s charging port, the microphone converts the signal to digital audio. It works via ADC after connecting the charging port.
I hope you can use these methods to listen to the external microphone for your iPhone. Thank you!
