[0004] The sound detector used by women and children doctors in medical work requires precision in sound detection, and doctors usually place the sound detector randomly after use, so that the dust in the air will enter the hollow structure of the listening head, There is dust attached inside, which changes the diameter of the listening head cavity, hinders the transmission speed of the sound, and reduces the accuracy of sound detection, and the dust is easy to fall from the listening head into the sound transmission tube wrapped with piezoelectric film material, which is easy to sound detection impact

Abstract
The present invention discloses a wearable sound detector based on a piezoelectric film. The wearable sound detector is structurally provided with a sound detection frame, a triangular support, a soft connecting pipe, a displayer and a touch detection head, the triangular support is fixedly connected to the bottom end of the sound detection frame in an embedded mode, one end of the soft connecting pipe is fixedly connected with the triangular support, and the other end of the soft connecting pipe is connected with the bottom of the displayer; the touch detection head is installed below one end of the display instrument and is matched with the display instrument, the ear of a person exerts pushing force on the driving body, the rear end of the warping block is pressed downwards while the warping block moves backwards, the linkage end is driven to be pressed and deformed, and the arc supporting block serves as a sliding fulcrum at the lower end of the warping block so that the warping block can warp and swing conveniently and drive the common connecting shaft to move upwards. When one end of the magnetic rod moves upwards along with the joint shaft, the magnetic rod tends to be in a transverse state and attracts the door blocking rod, so that the communication cavity is in a through opening state, sound transmission of personnel is facilitated, and after the hearing head is taken off, the driving body resets under the elastic action of the spring, and the door blocking rod plays a role in blocking dust at the port of the communication cavity.
Description
technical field [0001] The invention belongs to the field of piezoelectric materials, and more specifically relates to a wearable sound detector based on a piezoelectric film. Background technique [0002] With the development of modern science and technology, the electronic products that are constantly being developed also pay attention to the convenience of use on the basis of practicality. The wearable sound detector is an electronic device that can detect sound. It is implanted with piezoelectric film materials to make it In terms of sound recognition and detection, it overcomes the defects and limitations of traditional sound detectors such as interference and unstable flow. [0003] Based on the inventor's discovery above, the existing wearable sound detector based on piezoelectric film has the following deficiencies: [0004] The sound detector used by women and children doctors in medical work requires precision in sound detection, and doctors usually place the soun...
