Phone with vibrating speaker to transmit sound in the bone to the middle ear

Question

Audio

Please help me find a topic, as I came across a topic on Habré about a phone with a vibration speaker for transmitting sound through the bones of the skull to the inner ear or specific devices. Interested in both mobile phones and headsets. I want to buy for my grandmother, although I would buy for myself.

I think many will be interested in the topic of devices with similar functionality. A phone equipped with a "vibration speaker" is convenient for use in noisy environments, or for people with hearing impairments. If I buy something, I'll be sure to write a review.

Answer 1

It was not a phone that was considered, but an external vibration speaker.

Answer 3

Smart Sonic Receiver technology - transmits sound without the speaker or bones being heard.
