Abstract: A resonator includes a first sub-resonator and a plurality of second sub-resonators. The first sub-resonator in vibration deforms in at least two non-parallel directions. The first sub-resonator is connected to the second sub-resonators in all the at least two non-parallel directions, and deformations in all the at least two non-parallel directions couple the first sub-resonator to the second sub-resonators. Then, the resonator can balance a Q value and Rm, and can have a higher Q value and lower Rm.

Abstract: A temperature control apparatus includes a first fastening structure, a second fastening structure, two first support beams, two second support beams, a fastening frame, and a target component. The first fastening structure and the target component are located on an inner side of the fastening frame. The second fastening structure is located on an outer side of the fastening frame. The first fastening structure is connected to the fastening frame through the two first support beams. The second fastening structure is connected to the fastening frame through the two second support beams. The target component is fastened to the first fastening structure. A temperature difference between a first connection position and a second connection position that are on the fastening frame and that are respectively for connection to the two first support beams is less than a first preset value.
