A volume adjustment unit 25 for adjusting the gain and an earphone 26 are provided. It should be noted that various known modes can be applied to the signal acquisition unit 21 and the like, and a detailed description thereof will be omitted.

(Grip shape)
Next, the shape of the grip of the electronic stethoscope 200 according to the embodiment will be described with reference to FIGS. FIG. 2 is an external view of a grip of the electronic stethoscope according to the embodiment. 2 (a) is a top view of the grip, FIG. 2 (b) is a front view of the grip, FIG. 2 (c) is a bottom view of the grip, and FIG. 2 (d) is a grip. FIG. 2E is a rear view of the grip. FIG. 3 is an enlarged cross-sectional view illustrating a part of the grip according to the embodiment.

  In FIG. 2, the grip 10 of the electronic stethoscope 200 includes a sensoring part 11, a neck part 12, and a handle part 13 as an example of the “sensor housing part” according to the present invention.

  As shown in FIG. 3, the sensor ring unit 11 covers the sensor module 20 of the electronic stethoscope 200 from the outer peripheral side. The sensor module 20 includes at least a signal acquisition unit 21 (see FIG. 1).

  As shown in FIG. 3, the sensor ring portion 11 has an opening 11 a formed so as to expose a part of the sensor module 20. In addition, the sensor module 20 is being fixed to the sensor ring part 11 via the damper 20a.

  For example, as shown in FIG. 2D, the neck portion 12 has a surface including the opening 11a from the side opposite to the side where the opening 11a of the sensor ring portion 11 is formed (that is, a horizontal plane in FIG. 2D). Extending along the normal line direction (that is, the vertical direction in FIG. 2D).

  Here, in particular, the diameter of the neck 12 is reduced from the end of the neck 12 toward the center of the neck 12 in the direction in which the neck 12 extends (see FIGS. 2B, 2D, and 2E). . For this reason, when the user grips the neck 12 of the grip 10 with, for example, the thumb and the index finger, the user's finger can be prevented from slipping.

  The handle portion 13 is connected to the end portion of the neck portion 12 opposite to the end portion to which the sensor ring portion 11 is connected. The handle 13 extends in a direction intersecting with the direction in which the neck 12 extends (that is, in the left-right direction in FIG. 2D). Here, the direction in which the handle 13 extends is preferably a direction upward to some extent from the horizontal plane so that the user can easily hold it.

  As shown in FIGS. 2A and 2B, the handle portion 13 is formed with a recess 15 that is recessed toward the sensor ring portion 11. By providing the recess 15, for example, when the electronic stethoscope 200 is pressed against the subject, the user can appropriately apply force to the electronic stethoscope 200. Further, the user can prevent the electronic stethoscope 200 from rotating by attaching a finger to the recess 15.

  When the grip 10 is viewed from above, the shape of the recess 15 (that is, the shape of the recess 15 in FIG. 2A) is various, such as a water drop shape, an ellipse, a rectangle, a circle, a rectangle, and the like. The shape can be taken. From the viewpoint of the degree of freedom of how to hold the grip 10, it is desirable that the recess 15 has an elongated shape in which the direction in which the handle 13 extends is the longitudinal direction. Moreover, it is desirable that the cross-sectional shape of the concave portion 15 in the short direction (for example, the left-right direction in FIG. 2B) is a shape that becomes deeper from the end of the concave portion 15 toward the center of the concave portion 15.

  The handle portion 13 is provided with a protruding portion 14 that protrudes in a direction away from the sensor ring portion 11 (for example, upward in FIG. 2D). The shape of the protrusion 14 can take various shapes such as a columnar shape, a hemispherical shape, and a frustum shape. By providing the projection 14, for example, when the electronic stethoscope 200 is pressed against the subject, the user holds the neck 12 between the thumb and forefinger and holds the projection 14 on the mother and child balls of the hand by three points ( 4 (a)) becomes possible, and the grip 10 can be held more stably.

  A hole 14a is formed in the protrusion 14 (see FIGS. 2B and 2E). For example, if a neck strap, a reel clip, a band clip, or the like is attached to the hole 14a, the electronic stethoscope 200 can be suitably prevented from falling, and it is convenient when the user carries the electronic stethoscope 200.

  The handle portion 13 is provided with a cannon connector 16 for attaching a power cable or a signal cable, for example. For example, when the battery is built in the grip 10 and a signal is transmitted to the earphone 26 or the like via wireless, the canon connector 16 is not necessary.

  Here, since the sensoring part 11, the neck part 12, and the handle part 13 are hollow, it is possible to improve the degree of freedom in arranging the electronic stethoscope 200, for example, an electronic circuit.

  An example of the size of the grip 10 according to the embodiment will be described. The distance d1 in FIG. 2D (that is, equivalent to the entire length of the grip 10) is 95 mm (millimeters). The distance d2 in FIG. 2D (that is, the distance from the lower surface of the sensor module 20 to the upper surface of the end connected to the neck 12 of the handle 13) is 48 mm. In FIG. 2D, the distance d3 (that is, the distance from the lower surface of the sensor module 20 to the upper surface of the protrusion 14) is 76 mm. The distance d4 in FIG. 2A (that is, the length in the longitudinal direction of the handle 13) is 86 mm. The distance d5 in FIG. 2E (that is, corresponding to the diameter of the sensor ring portion 11) is 45 mm.

(How to hold the grip)
Next, an example of how to hold the grip 10 configured as described above will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of how to hold the grip of the electronic stethoscope according to the embodiment.
