Yes. You can demonstrate this for yourself. Use a small nail or screw to make a small hole in the bottom of each of two empty tin cans.

How is it that you can hear someone talking using a tin can phone?
Sound is caused by the vibration of the molecules in a medium. In most cases, this is air, but sometimes can be other materials (screaming underwater, metal on the traintracks). In the tin can phone, the string carries the vibration from one end to the other, where it vibrates the air and becomes normal sound again.
How does a tin can telephone work?
Required: Two tin cans, a length of string. A small hole is made in the bottom of each can large enough for the string diameter. The string is pushed through the hole in bottom of each can and a large knot tied to prevent it from pulling back through the hole. when the string is kept taught between the cans, it is possible to transmit and receive sounds from one can to the other via the taught string. The string acts as a mechanical sound conductor. Increased efficiency can be achieved by substituting suitable wire for the string. Of course if you want to cheat - just use your I-phone!
How do sound waves travel through string?
This is a complex question - or rather the answer could be.In a violin for example, the strings rotate as well as vibrate.In a simple 'string and tin can phone" the waves are transverse waves carried by the taut string.Basically, your string can vibrate back and forth, normal to the string;or it may rotate round the axis along the string;or a mass may swing suspended by the string as in a pendulum.
