摘要：
A detection head of a stethoscope comprises a detection head body (1, 2, 8) and a sound guiding conduit in the detection head body (1, 2). The sound guiding conduit comprises a sound collecting surface (12, 23), a sound guiding pore (D), and a lateral sound guiding aperture (4). The sound collecting surface (12, 23), the sound guiding pore (D), and the lateral sound guiding aperture (4) are disposed on the detection head body (1, 2, 8), and in combination with each other. At least a part of the detection head body (1, 2, 8) is made of a second density material. The density of the material of a sound guiding layer (3, 5, 6, 7, 9A) on the sound collecting surface (12, 23) is greater than that of the second density material. The detection head (1, 2, 8) of a stethoscope has advantages of light in weight, low in cost, and not affecting the sound-listening performance.
