The present invention relates to a point-pressed audio pickup apparatus applied to receive various physiological sounds (e.g., audio signals generated by the movement of heart, lungs, internal organs or internal tissues) thereby facilitating medical diagnoses.
It is well-known in conventional technologies that audio pickup devices can be used to receive various kinds of physiological sounds in the human body; in particular, the so-called stethoscope can be applied for medical purposes. Currently there are old-fashioned wired stethoscopes and wireless electronic stethoscopes, but no matter the wired stethoscope or the wireless electronic stethoscopes, they are mostly equipped internally with a contact-typed microphone in order to perform audio pickup when the stethoscope touches the human body.
However, during such sound pickup or reception processes, it is likely there may also exist certain rubbing sounds generated when the stethoscope moves or various environmental sounds during operations, and these unwanted noises may seriously affect the original physiological sounds and interfere with the medical staff for correct diagnoses. Therefore, the present invention provides a point-pressed audio pickup apparatus which adopts a type of point-pressures pickup method such that, as moving the audio pickup apparatus to a predetermined position, the user can receive the intended physiological sounds only when an external force is applied thereto at a single point so as to greatly reduce the noises generated during operations, thereby offering an effective solution for the aforementioned issues.
The present invention discloses a point-pressed audio pickup apparatus, comprising a deformation element and an audio pickup device, wherein the deformation element includes a first surface, a second surface and a joint block joined between the first surface and the second surface, in which any one or more of the first surface, the second surface and the joint block can induce deformation by an external force, and an audio pickup hole is openly configured at the central position of the first surface; the audio pickup device includes an audio pickup element installed inside the audio pickup hole, and a conduction element and a distance sensing element installed inside the deformation element, in which the audio pickup element and the distance sensing element are respectively electrically connected to the conduction element, and the distance sensing element is correspondingly installed by the side of the first surface; accordingly, the first surface is attached to the surface of an object in order to push or press the deformation element by an external force vertical to the first surface to induce deformation, such that the first surface or the second surface displaces in the vertical direction thereby reducing the distance between the first surface and the distance sensing element, so that the distance sensing element can operate to measure the distance length, and the audio pickup element will be triggered to receive sound when the measured distance length reaches more than 1 μm.
In a preferred embodiment, the deformation element is installed on an electronic device, the conduction element is also electrically connected to a control element within the electronic device, and the control element is further electrically connected to a sound playback device.
In a preferred embodiment, the distance sensing element and the conduction element are both installed on the second surface, and the distance sensing element corresponds to the first surface.

In a preferred embodiment, the first surface, the second surface or the joint block designed to have continuous bumpy wave forms are fabricated with flexible materials.
In a preferred embodiment, the first surface designed to have a continuous bumpy wave forms has a protrusion formed towards outside.
In a preferred embodiment, any one or more of the first surface or the second surface are openly configured with a plurality of holes at the same time.

Now, refer to
Herein the illustrated deformation element 1 includes a first surface 11, a second surface 12 and a joint block 13 joined between the first surface 11 and the second surface 12, in which any one or more of the first surface 11, the second surface 12 and the joint block 13 can induce deformation by applying an external force, and an audio pickup hole 111 is also openly configured at the central position of the first surface 11.
Meanwhile, the audio pickup device 2 includes an audio pickup element 21 installed inside the audio pickup hole 111, and a conduction element 22 and a distance sensing element 23 installed inside the deformation element 1, in which the audio pickup element 21 and the distance sensing element 23 are respectively electrically connected to the conduction element 22, and the distance sensing element 23 is correspondingly installed by the side of the first surface 11 or the second surface 12.
Herein, upon operating the deformation element 1 on human skins and sliding onto a predetermined position, it is possible to use an external force to vertically push or press the deformation element 1 such that it induces deformation to allow the first surface 1 or the second surface 2 to move in the vertical direction thereby reducing the distance between the first surface 11 and the distance sensing element 23, so that in case the distance sensing element 23 detects the length L of the distance reaches 1 μm or more, it triggers the audio pickup element 21 to start to receive various physiological sounds in the human body (e.g., audio signals generated by the movement of heart, lungs, internal organs or internal tissues). Moreover, the audio pickup element 21 then receives such physiological sounds and digitalizes them into an audio file to pass into the conduction element 22; subsequently, when operating once again the deformation element 1 on human skins and sliding onto the next predetermined position, the external force vertically pressing the deformation element 1 will be released so that it can restore to the original form thus canceling the operation condition for triggering the audio pickup element 21. Therefore, the physiological sounds can be received only when the external force is applied at a single point, which can greatly reduce noises generated during the operation.
