Description

Technical Field

[0001] The utility model relates to the technical field of sound transmission, in particular to an auxiliary sound transmission device. Background Art

[0002] An assistive hearing device is a medical device designed to help people who cannot hear sound clearly through conventional hearing pathways due to inner or middle ear problems, allowing the patient to hear sounds more clearly.

[0003] After searching: Chinese patent publication number: CN213155993U, it relates to the field of medical device technology, and discloses a multifunctional stethoscope device for clinical cardiology, including a sound pickup part, a conduction part, a listening part and an auxiliary part. The multifunctional stethoscope device for clinical cardiology solves the problem that the doctor's ear will hurt after wearing the stethoscope for a long time by using a protective pad whose shape matches the shape of the auricle and a threaded sleeve for threaded connection. The protective pad is made of sponge material to isolate external noise, and solves the problem that the sound heard by the stethoscope is too small to be heard, which affects the diagnosis and listening effect. It ensures clear sound and intuitively reflects the patient's condition. Electrode 1 and electrode 2 are used to collect electrocardiograms of the human body, and the display box is used to intuitively display the information so that the doctor can better understand the patient's condition. At the same time, it cooperates with the timer inside the display box to better judge the condition, and the insulation ring is used to isolate the error caused by the stethoscope head.

[0004] The above patent embodiment states that "by using a protective pad 35 whose shape is adapted to the shape of the auricle and threadedly connected to the threaded sleeve 33", since the protective pad 35 is made of sponge material, it can isolate external noise and solve the problem that the sound heard by the stethoscope is too small to be heard, which will affect the diagnosis and hearing effect. However, external noise will still interfere with the user and affect the hearing. Therefore, in view of the above-mentioned deficiencies, a new auxiliary hearing conduction device is now proposed.
