On the iPhone, you can vibrate (vibrate) the body at the timing when a specific notification arrives, such as calling for telephone or e -mail, and AirDrop.However, depending on the condition of the iPhone, you may not notice the vibration.Maybe some people want to make the vibration sound a little louder.
Unfortunately, the vibration size, that is, the vibration created by Taptic Engine inside the iPhone cannot be adjusted.The vibration of successive iPhones, including the latest iPhone 13, does not have a function to adjust the degree of vibration, so the vibration sound itself cannot be enhanced.
The easiest way to take it is to put the iPhone in a place where vibration is easy to convey.Although the magnitude of the vibration cannot be changed, if the iPhone is attached to an object that is moderately light and easy to tremble, the sound of the vibration can be amplified and easier to hear.
I experimented with various materials, but thick glass tables seemed to rarely convey vibration, but rather counterproductive.It is a level that you do not even notice that the iPhone is vibrating.Wood products such as tables and flooring floors may not notice that the surroundings are noisy, although the vibration sound is louder than the glass.The same is true for magazines and books that are full of eyes.
The most effective was a polystyrene food tray that was often seen in supermarkets.If you put your iPhone on a desk and put your iPhone and vibrate it, you will hear a loud noise.Perhaps because the structure similar to the drums is amplified.
Recommended is a sofa.I tried it with a leather, but the moderate toughness enhances the sound of the vibration so that it does not get harsh.The sofa cushions also have the impression that the sound is likely to absorb the sound, but it has a loud noise than a wooden table.It is unrealistic to always put the iPhone on a food tray, but you can operate a sofa or cushion without difficulty.
