Abstract

The utility model provides an electronic tuning fork, includes the casing, is equipped with speaker, mainboard and battery on the casing, battery respectively with mainboard, speaker electric connection, be equipped with electric connection's CPU module, audio module, preamplification module and power amplifier module in proper order on the mainboard, power amplifier module and speaker electric connection. The utility model discloses in, the CPU module is used for controlling the audio frequency that the audio frequency module selected different frequencies, then plays out through the speaker after handling via pre-amplification module and power amplifier module to make the electron tuning fork can play the sound of different frequencies, realize changing the function of frequency.

Description

Electronic tuning fork

Technical Field

The utility model relates to a tuning fork technical field especially involves an electron tuning fork.

Background

The tuning fork is often used for hearing and deep-sense examination in clinical examination, particularly for the deep-sense examination, which belongs to the important content of sensory function examination, the common method is that a doctor closes eyes of a patient, uses the vibrating tuning fork to be placed at the bone ridge of the limb of the patient, and knows whether a deep-sense conduction path of the patient is influenced or not according to the existence of the vibration sense of the patient, so as to detect whether the hearing of the patient is influenced or not.

The existing common tuning fork can only emit one frequency during inspection, so that the inspection needs to replace tuning forks with different frequencies, which is inconvenient to some extent.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above-mentioned technical problem, provide an electronic tuning fork, this electronic tuning fork can realize changing the function of frequency.

In order to realize the utility model discloses an aim, the technical scheme who adopts is: the utility model provides an electronic tuning fork, which comprises a housin, be equipped with speaker, mainboard and battery on the casing, the battery respectively with mainboard, speaker electric connection, be equipped with electric connection's CPU module, audio module, preamplification module and power amplifier module in proper order on the mainboard, power amplifier module and speaker electric connection.

As a further improvement, the casing is further provided with a button, and the button is electrically connected with the CPU module.

As a further improvement, the casing is further provided with a display screen, and the display screen is respectively connected with the battery and the CPU module electrically.

As a further improvement of the utility model, be equipped with the protective sheath on the speaker.

The utility model has the advantages that: the CPU module is used for controlling the audio module to select audio frequencies with different frequencies, and then the audio frequencies are played through the loudspeaker after being processed by the pre-amplification module and the power amplification module, so that the electronic tuning fork can play sounds with different frequencies, and the function of changing the frequencies is realized.

Detailed Description

The present invention will be further described with reference to the following embodiments and accompanying drawings.

As shown in fig. 1-3, an electronic tuning fork comprises a housing 1, and a speaker 2, a main board 3 and a battery 4 are disposed on the housing 1. The battery 4 is electrically connected with the main board 3 and the speaker 2, respectively. The main board 3 is provided with a CPU module 31, an audio module 32, a pre-amplification module 33 and a power amplification module 34. CPU module 31, audio module 32, preamplification module 33 and power amplifier module 34 are connected with each other electrically in turn, and power amplifier module 34 is connected with loudspeaker 2, and loudspeaker 2 is provided with protective sheath 21.

The CPU module 31 is configured to control the audio module 32 to select audio with different frequencies, and then play the audio through the speaker 2 after being processed by the pre-amplification module 33 and the power amplification module 34, so that the electronic tuning fork can play sound with different frequencies, thereby implementing a frequency replacement function.

Still be equipped with button 5 and display screen 6 on the casing 1, CPU module 31 still respectively with button 5 and display screen 6 electric connection, display screen 6 and battery 4 electric connection. The frequency selection, play, pause, etc. are controlled by the keys 5. The current frequency, power and other information are displayed through the display screen 6.

The embodiment is only used to conveniently illustrate the present invention, and is not intended to limit the present invention in any form, and any person who knows the knowledge in general in any field of the art can use the disclosed technical content to make local changes or modified equivalent embodiments without departing from the technical features of the present invention, and the technical features of the present invention are not separated, and all the equivalent embodiments belong to the technical features of the present invention.
