摘要：
A detection head of a stethoscope comprises a detection head body (1, 2, 8) and a sound guide channel in the detection head body (1, 2). The sound guide channel comprises a sound collecting surface (12, 23), a sound guide hole (D), and a side sound guide hole (4). The sound collecting surface (12, 23), the sound guide hole (D), and the side sound guide hole (4) are disposed on the detection head body (1, 2, 8), and in communication 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 guide 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.
