What Does Auxiliary Port (AUX) Mean?

An auxiliary port (AUX) is a type of standard communications port on a device that accommodates audio signals for:

MP3 players.Headphones & headsets.Microphones.Speakers .And other audio devices, including some fairly traditional audio technologies.

If you plug speakers or mics or headsets into a primary device, with the possible exception of some types of USB setups, you’re typically connecting in through what you would call an auxiliary port.

Computer port 1 (COM1) on a traditional PC is typically configured as an audio aux port. Which is the first serial port with a preconfigured assignment for serial devices.

An RS-232 standardization applies lớn various PC audio attachments, many of which are converted lớn the 3.5mm or “1/8 inch” standard audio jack on a lot of peripheral hardware.

Generally, the use of these audio ports requires different types of adapters & fittings for backward compatibility as system components evolve from many different manufacturers.

Here’s more on how this type of system worked on traditional PC platforms: the general thiết kế involved system resource configurations on a PC where engineering selected these for each port, i.e.: COM1, COM2, COM3, COM4, etc.

Each COM location had an interrupt request (IRQ) address và input/output (I/O).

The IRQ address is a signal sent from a device lớn the central processing unit (CPU) specifying an event, such as an audio signal starting or stopping.

More recently, auxiliary ports and auxiliary jacks became important for the widespread distribution of digital music, through trang chủ or car speakers, or directly from a device. So the auxiliary jack và its corresponding port became extremely useful khổng lồ users.

That is particularly true in the điện thoại cảm ứng thông minh world, where the single auxiliary jack provides for so many different uses, for example, watching movies or television programming with high-quality audio direct to your headphones, playing music through headphones, participating in conference calls through a headset, etc.

With that in mind, one of the most significant pivotal changes in Apple’s điện thoại thông minh design philosophy occurred when táo bị cắn took the conventional auxiliary port away from newer iPhone models.

This required the purchase of specialized headsets and other gear that plug in through the lightning port. While defended vehemently by Apple, the move was unpopular with a wide range of users, và remains an example of unanticipated interface problems that are created by the manufacturer.

Generally speaking, now that many standard auxiliary reports are becoming obsolete, companies are finding ways lớn make new systems backward-compatible lớn older devices, or in other words, to lớn adapt older devices khổng lồ play music.

New điện thoại thông minh models have a universal audio port design, at least, they did until the idea of Lightning-port-audio came along.

Now, the debate around audio connectivity is a major interest in the thiết bị di động device world. Increasingly, wireless thiết kế is making the auxiliary port obsolete.

Another design principle is the “build in” of input devices and peripherals into primary devices. Examples include the shift from USB-connected webcams lớn cameras built into laptops, và the move from traditional mouse designs khổng lồ trackpads and touchscreen interfaces.

Now, we use auxiliary ports less, because there are fewer peripheral devices lớn connect them to.

All of this prefigures a new mix of interface paradigms that will continue to lớn evolve in the điện thoại thông minh era, where the auxiliary port is much less of a presence than it used to lớn be.
