Guide to Thermal Transfer Labels: Technology, Materials, Printers, and Direct Thermal Comparison
Publié par JiangDavid le
Have you ever dealt with a shipping label that smeared in the rain? Or a barcode that faded under warehouse lights, becoming unscannable? These common frustrations highlight the need for durable, reliable labeling. For many businesses, the answer lies in thermal transfer labels. Thermal transfer printing with the right label is key for durable, high-quality results. This guide explores the technology, compares it to direct thermal, details thermal transfer label types (like polyester and industrial), covers label printers, and highlights key applications. What Are Thermal Transfer Labels? Thermal transfer labels are printed using a process that involves a thermal printhead and a...

Speaker Horn | Define,Types&Choose
Publié par JiangDavid le
A horn speaker is a type of loudspeaker that utilizes a horn to enhance the overall efficiency of its driving element, typically a diaphragm or compression driver. The horn amplifies the sound produced by the driver by improving the coupling between the speaker driver and the air. This results in a more efficient energy transfer, leading to higher sound levels and better directionality. Currently, horn speakers are widely used in IP/ PA systems for their ability to deliver clear and powerful sound over long distances.

How a Loudspeaker Makes Sound
Speakers make sound by using magnetism and electric current to move air, creating sound waves.
Inside a speaker, there is a strong magnet that stays in place. A coil of wire, called the voice coil, sits in a small gap near this magnet and is attached to a thin surface called the diaphragm. When an audio signal is sent to the speaker, electricity flows through the voice coil. This creates a magnetic field, turning the coil into a temporary magnet.
Since the audio signal is always changing, the voice coil’s magnetism changes too. This makes it push and pull against the fixed magnet. As a result, the voice coil moves back and forth, carrying the diaphragm with it.
The diaphragm’s movement pushes the air, making areas of high and low air pressure—these are sound waves. When these waves reach our ears, we hear sound.
The speed of the voice coil’s movement depends on the audio signal. A fast-moving coil creates high-pitched sounds, while a slow-moving coil makes low-pitched sounds.
In short, electricity creates a magnetic force, which moves the voice coil, which moves the diaphragm, which moves the air—turning electrical signals into sound.
