The invention discloses a kind of radio electron echometers, including sound transducer and supra-aural earphone, sound transducer is connected with supra-aural earphone using wireless mode, the display for real-time display acquisition data is provided on sound transducer, in the single-chip microcontroller that is internally provided with of sound transducer, sound transducer is connect with the single-chip microcontroller being arranged in inside sound transducer.It is the configuration of the present invention is simple, easy to use comfortable, low in cost.
Description
Technical field
The invention belongs to medical device technical fields, and in particular to a kind of radio electron echometer.
Background technique
Currently, common stethoscope is passed in ear through metal vibration diaphragm in stethoscope probe, then by the pipeline operatic tunes, doctor
It takes root and is judged according to its sound, this stethoscope occupies main positions in medical diagnosis, played an important role.But
It is this stethoscope is often hung on the neck of doctor, fatigue or uncomfortable is easy to produce, in use, cochlea is often subject to come from
The spring pressure of earphone, is affected to medical staff, has discomfort using more.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is that providing a kind of structure letter
Radio electron echometer single, low in cost, easy to use.
The invention adopts the following technical scheme:
A kind of radio electron echometer, including sound transducer and supra-aural earphone, sound transducer and supra-aural earphone
It is connected using wireless mode, the display for real-time display acquisition data is provided on sound transducer, in sound transducer
Be internally provided with single-chip microcontroller, sound transducer is connect with the single-chip microcontroller being arranged in inside sound transducer.
Further, it is provided with wireless transmitter module in sound transducer, wireless receiving module is provided in earphone, wirelessly
The tranmitting frequency of transmitting module and wireless receiving module to receive frequency identical.
Further, the outside of sound transducer is provided with switch, and switch is connect with wireless transmitter module.
Further, wireless transmitter module and wireless receiving module are using in bluetooth, 802.11b/g, 2.4GHz and 5GHz
One kind.
Further, sound transducer successively passes through preamplifier, high-pass filter and audio sample device and single-chip microcontroller
Connection, single-chip microcontroller are connected separately with display and wireless transmitter module, and the sound that display is used to acquire sound transducer passes through
It crosses after single-chip microcontroller is converted into waveform and diagnosis and shows.
Further, high-pass filter is 50Hz filter.
Compared with prior art, the present invention at least has the advantages that
1, using wireless transmission, remote transmission is realized, it can be achieved that more people are shared, is conducive to hold a consultation and impart knowledge to students.
2, high-pass filter is configured, transmission is more stable, and effect is more preferable.
3, the voice signal of acquisition is transformed into after enhanced processing figure signal, and is diagnosed, make to check diagnosis
More intuitive, analysis is more convenient.
4, structure is simple, easy to use comfortable, low in cost.
Below by drawings and examples, technical scheme of the present invention will be described in further detail.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the embodiment of the present invention；
Fig. 2 is stethoscope earphone schematic diagram of the present invention.
Wherein: 1. sound transducers；2. wireless transmitter module；3. switch；4. display；5. earphone；6. wireless receiving mould
Block.
Specific embodiment
Fig. 1 and Fig. 2 are please referred to, the invention discloses a kind of radio electron echometers, including sound transducer 1 and supra-aural
Earphone 5 is provided with wireless transmitter module 2 in sound transducer 1, wireless receiving module 6, sound transducer 1 is provided in earphone 5
It is wirelessly connected with earphone 5, the display 4 for real-time display acquisition data is provided on sound transducer 1, wirelessly
Transmitting module 2 is connect with the switch 3 being arranged in outside sound transducer 1, controls its work by switch 3, wireless transmitter module 2
Tranmitting frequency and wireless receiving module 6 to receive frequency identical.
Sound transducer 1 is successively by preamplifier, high-pass filter, audio sample device and single-chip microcontroller and wireless hair
Penetrate the connection of module 2, the sound for that will acquire after treatment, using high pass filter, processes,
Preferably, high-pass filter is 50Hz filter；
Wireless transmitter module 2 includes one of bluetooth, 802.11b/g, 2.4GHz, 5GHz, nRF2401, for wireless
Connect computer.
Display 4 is used to show the sound that sound transducer 1 acquires after single-chip microcontroller is converted into waveform and diagnosis
Show.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
According to technical idea proposed by the present invention, any changes made on the basis of the technical scheme each falls within claims of the present invention
Protection scope within.
