An acoustic (sound or ultrasound) wave transmitter having a plurality of waveguides is described, and a method of making such a transmitter is described. Each waveguide can have a cladded core. The core can be a liquid such as water, alcohol or mineral oil. Alternatively, the core can be a colloidal gel, such as gelatin dissolved in at least one of water, vinyl plastisol or silicone gel. The cladded core is capable of transmitting acoustic wave energy from a first end surface to a second end surface of the cladded core. The waveguides can be substantially fixed relative to each other by a binder. The binder can be formed by fusing the claddings together, potting a material between the waveguides and/or mechanically holding the waveguides.
