An inertial force sensor may comprise: a base; a first block including an inclined surface that is inclined with respect to a base surface; a second block including an inclined surface that is inclined with respect to the base surface; a third block including an inclined surface that is inclined with respect to the base surface; a fourth block including an inclined surface that is inclined with respect to the base surface; and a connector configured to physically connect the first, second, third, and fourth blocks. In this inertial force sensor, the first and second blocks are aligned along a first direction parallel to the base surface with their inclined surfaces both facing inward or outward, and the third and fourth blocks are aligned along a second direction parallel to the base surface and orthogonal to the first direction with their inclined surfaces both facing inward or outward.

An electronic device and a sound recording method for the electronic device are provided. The electronic device includes a housing; a camera module, where the camera module is disposed in the housing and includes a movable support, and the movable support is provided with a lens assembly and is movably disposed on the camera module; and a microphone module, where the microphone module is disposed on the movable support.
