A kind of combined type stethoscope diaphragm unit, comprise that the encapsulate body divides 1 and diaphragm 4, and diaphragm 4 is circular film, is a kind of fiberglass resin sheet, and its diameter is 37.5mm.
The encapsulate body divides 1 to comprise the first endless belt platform 2 and the second endless belt platform 3.Wherein, the diameter of the first endless belt platform 2 is less than the diameter of the second endless belt platform 3, between the first endless belt platform 2 and the second endless belt platform 3, the first annular sidewall 5 is set, edge at the second endless belt platform 3 is provided with the second annular sidewall 6, the second annular sidewalls 6 towards the extension of the direction away from the first endless belt platform 2.Wherein, the first end of the first annular sidewall 5 is connected with the external diameter edge of the first endless belt platform 2, and the second end of the first annular sidewall 5 is connected with the internal diameter edge of the second endless belt platform 3.
The first endless belt platform 2 is 2.0mm with the vertical height sum H of circular film, thereby makes the detection audio frequency more press close to the actual audio that patient's internal organs send.The impact of diaphragm deformation on hearing effect when simultaneously, it also can avoid contacting skin surface.
The first endless belt platform 2 and the second endless belt platform 3 are parallel to each other and are coaxial and the first endless belt platform 2, the second endless belt platform 3, the first annular sidewall 5 and the second annular sidewall 6 are one-body molded.
The external diameter of circular film equates with the external diameter of the first endless belt platform 2, and circular film is pasted on the first endless belt platform 2, to guarantee that circular film contacts with the direct of patient body.
In conjunction with Fig. 1 and 6, the combined type stethoscope diaphragm unit in embodiment 1 and high-tension transmutability combined membrane of the prior art are carried out to audio-frequency test.
The sound source decibel is 114dB, and the testing audio frequency is respectively 1000Hz, 500Hz, 250Hz.
The circular film specification: circular film is fiberglass resin sheet, and diameter is 38mm, and thickness is 0.2mm.
In prior art, the dimensions of circular film top encapsulate thickness d is respectively: 0.7mm, 0.55mm, 0.40mm, 0.25mm.
In embodiment 1, the dimensions of the encapsulate thickness d on circular film top is 0mm, and there is not encapsulate in circular film top.
Audio-frequency test the results are shown in Table 1, and table 1 is as follows:
Table 1
The encapsulate thickness d on the audio value after the decay and circular film top is roughly linear as shown in Table 1, the encapsulate thickness d on circular film top is less, audio value after decay is larger, be that audio damping is less, until the encapsulate thickness d on circular film top is 0mm, when there is not encapsulate in circular film top, the audio value maximum after decay, be the audio damping minimum, now the acoustic effect is best.
Below only with embodiment, this utility model is illustrated, but this utility model is not limited to above-mentioned size and outward appearance illustration, more should not form any restriction of the present utility model.As long as within any improvement that this utility model is done or modification all belong to the protection domain of this utility model claim opinion.
