We mentioned two design changes during the Evaluation of Samsung Galaxy Note10.

One is a hidden earpiece. In fact, Note10 has three speakers: one at the bottom, one at the top of the middle frame, and one hidden at the top of the front camera, which is the gap of the frame. Location, because its location is too hidden, so many users have thought that Note10 uses screen sound technology.

There is also a linear motor. We actually found in the hand that, compared with the S10, the Note10 has a significantly lower amplitude at the same vibration intensity, and the subjective feeling is “softer”.

At the same time, Samsung officially stressed that the cancellation of the 3.5mm headphone jack also brings better tactile feedback to Note10, because the headphone hole is also equivalent to a part of the fuselage cavity, which is equivalent to changing the phone by adjusting the sealing structure. The sense of vibration feedback.

However, behind these design changes, what adjustments has Samsung made in its internal structure? Today, we can see some clues from the disassembly report of iFixit .

The first is the hidden earpiece. As you can see from the disassembly diagram, this earpiece is really only as wide as a slit, and the real speaker module is not placed behind the earpiece, but below the front camera module.

So how is the sound transmitted? In fact, this speaker module is embedded inside a metal frame. When the sound is emitted, the sound wave can be guided by the metal material to the small gap at the top of the frame.

This also explains why we feel that the sound is emitted from the inside when we use Note10, but its external effect is still amazing, even the screen and the upper part of the fuselage can feel continuous and slight vibration.
