Thermoacoustic device with flexible fastener and loudspeaker using the same

A loudspeaker comprising:

• a base;
• a plurality of first fasteners, each of the plurality of first fasteners comprising a body engaging with the base and a flexible element extending from the body;
• at least one linear first electrode having a first end and a second end, wherein the first end engages with the flexible element of one of the plurality of first fasteners, and the second end is secured on the base;
• at least one linear second electrode substantially parallel to the at least one linear first electrode, the at least one linear second electrode having a third end and a fourth end, wherein the third end engages with the flexible element of one of the plurality of first fasteners, and the fourth end is secured on the base;
• and
• a sound wave generator comprising a carbon nanotube structure electrically connected to the at least one linear first electrode and the at least one linear second electrode;
• wherein the flexible element has elasticity in a direction from the first end to the second end of the at least one linear first electrode, and the first end and the third end are not engaged to the same flexible element.
