Detection device

Abstract

This invention provides a technology to facilitate the application of the detection device to the subject. [Solution] The detection device for detecting vibrations of a subject comprises a diaphragm that deforms in response to the vibrations of the subject, a chestpiece including the diaphragm, and a gripping portion including a part that is gripped by a user of the detection device, wherein the chestpiece is coupled to the gripping portion so as to be pivotable relative to the gripping portion, the outer surface of the gripping portion includes a pressing surface for the user of the detection device to apply force to press the chestpiece against the subject, and the chestpiece is pivotable relative to the gripping portion such that the pressing surface is parallel to the outer surface of the diaphragm.

Claims

[Claim 1] A detection device for detecting vibrations of a subject, A diaphragm that deforms in response to the vibration of the subject, A chestpiece including the diaphragm, The device comprises a gripping portion including a part that is grasped by a user using the detection device, The chestpiece is coupled to the gripping portion so as to be pivotable relative to the gripping portion, The outer surface of the gripping portion includes a pressing surface for the user of the detection device to apply force to press the chestpiece against the subject, The detection device wherein the chestpiece is pivotable relative to the gripping portion such that the pressing surface is parallel to the outer surface of the diaphragm. [Claim 2] The detection device according to claim 1, characterized in that, in a plan view of the outer surface of the diaphragm, the pressing surface coincides with the center of the diaphragm. [Claim 3] The detection device according to claim 1, characterized in that the pressing surface is flat. [Claim 4] The detection device according to claim 1, characterized in that the pressing surface has rigidity. [Claim 5] The detection device according to claim 1, characterized in that, when the pressing surface is parallel to the outer surface of the diaphragm, there is a gap of 20 mm or more between the portion of the gripping part that is gripped by the user and the plane passing through the outer surface of the diaphragm. [Claim 6] The chestpiece includes a pivot shaft attached to the gripping portion, The detection device according to claim 1, characterized in that the chestpiece is pivotable about the pivot axis relative to the gripping portion. [Claim 7] The detection device according to claim 6, characterized in that, in a plan view of the diaphragm with respect to the outer surface, the axial direction of the pivot axis is perpendicular to the longitudinal direction of the gripping portion. [Claim 8] The detection device according to claim 6, characterized in that, in a plan view of the outer surface of the diaphragm, the pressing surface overlaps the pivot axis. [Claim 9] The diaphragm includes a reflective surface that moves in response to the vibration of the subject, The detection device is A light-emitting element that emits light toward the reflective surface, The detection device according to claim 1, further comprising a light-receiving element that receives reflected light reflected by the reflective surface and outputs a signal corresponding to the reflected light.
