Example

This embodiment provides a fetal teaching instrument, as shown in FIG. 1, comprising:

- The housing 1 is formed by the two sides being engaged with a receiving cavity therein, and one side of the housing 1 is a circular arc surface 12 (this surface is used for prenatal education), in order to better approximate the curvature of the abdomen arc of the pregnant woman 0.06-0.1, such as 0.06, 0.08, 0.1, preferably 0.08, two arc-conducting speakers 3 are arranged on the arc surface, and the distance between the axes of the two bone conduction speakers 3 is 12-18 cm, such as 12 cm, 14 cm, 16 cm, 18 cm or the like, the bone conduction speaker 3 is composed of a front cover 31, a rear cover 32, and a vibrator located between the front cover 31 and the rear cover 32. The rear cover 32 includes a plurality of mounting holes around the center and a through hole through which the wire passes. The back cover bottom plate 321 is provided with a plurality of parallel ribs 322 disposed on the inner surface of the rear cover 32. The top surfaces of all the ribs 322 are coplanar and parallel with the inner bottom surface of the front cover 31.
