How Do 1cm Headphone Speakers Provide Deep Bass?

The speakers inside our headphones are not even 1 cm away! Despite this if If we have good headphones, we can feel the bass wonderfully. isn’t it?

With such small speakers The answer to how our headphones produce bass is lies in the physics of sound!

First, let’s remember how sound propagates.

When we talk about the propagation of sound, there is an image that comes to our mind: propagating vibrations. Sound, waves in a pool It moves by spreading like. Bass frequency has long wavelengths and periods.

Upper, high frequency; lower, low frequency

Therefore, it is more likely to spread and disappear. The larger the speaker, the better the chance of creating big waves. So what makes headphones different?

Headphones don’t work outdoors like large speakers.

Many of the headphones are between our ears. a small tunnel It creates. So there isn’t much air in between. An in-ear speaker placed in our ear canal fits with our eardrum and can produce plenty of bass despite its small size.

In addition, the situation called “bone conduction” plays a big role in the bass production of our headphones. sound vibrations, directly into the bones of our skull being sent. While our eardrums do not react much to frequencies below 80 Hz, our brain can perceive frequencies up to 20 Hz. Bass frequencies resonate (in simple terms, vibrate) in our body cavities such as the chest and stomach.

In-ear headphones press directly on our skull, transmitting bass frequencies, directly to the inner ear via bone conduction transmitting. On-ear headphones, on the other hand, do not come into direct contact with the skull. Therefore, to get the best bass experience, you can choose in-ear headphones that will fully enclose your ear.

Headphones are already designed with the bass factor in mind.

Many headsets use specially designed cabinets or acoustic chambers. More effective sound at low frequency can produce. In addition, headphones with low external noise and blocked air intake ensure that bass frequencies become clearer.

When all these factors come together, our tiny headphones can produce impressively deep bass frequencies. Of course from brand to brand, from model to model changes occur.
