Description
Technical Field
The utility model relates to a neck-wearing type electronic artificial larynx.
Background
Speech is the most basic, effective and important means of communication for humans as a carrier of language. The voice can not only transmit the language information, but also transmit the personal information and the emotion information of the speaker. Statistical data at home and abroad show that millions of laryngeal cancer patients and serious laryngeal patients in the world lose vocal function and speech function due to laryngectomy and the like, and the number of the patients is increased year by year. Not only do they suffer from injury and pain caused by laryngectomy, but also the quality of life is significantly reduced due to the loss of voice function, and these patients can use speech rehabilitation assistive devices to rebuild the voice function. The electronic artificial larynx has been a speech assisting device for more than 50 years, the working principle of the existing electronic artificial larynx is simple, the electronic artificial larynx is held against the larynx by a handle when a patient uses the electronic artificial larynx, excitation pulses controlled by a switch are converted into mechanical vibration and then applied to the neck of the patient, the vibration is transmitted into a sound channel through neck tissues, and the sound channel is modulated to generate voice. The existing electronic artificial larynx is generally held by one hand of a patient and pressed on the neck, or a special neck support is required to be equipped, so that the electronic artificial larynx is inconvenient to use.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects that the existing electronic artificial larynx needs to be held by hands or a special neck support needs to be equipped, the utility model provides a design mode of a wearable electronic artificial larynx.
The scheme adopted by the electronic artificial larynx of the utility model is as follows: the neck-wearing type design mode is adopted, the electric-power conversion part of the electronic throat is installed at one end of the neck strap, the excitation generating circuit part is installed at the other end of the neck strap, the control switch is wirelessly connected with the excitation generating circuit in a Bluetooth mode, and a user remotely controls the excitation generating circuit to generate excitation pulses through the control switch.
When the electronic artificial larynx is used, a user only needs to press and touch the control switch by fingers, and a switch signal of the control switch is transmitted to the excitation generating circuit in a wireless mode to drive the electronic artificial larynx to work.
The beneficial effects of the utility model include: the user does not need to hold the electronic artificial larynx with hands specially, and the wearing type design makes the use of the electronic artificial larynx more convenient.
According to an aspect of the present invention, there is provided an electronic artificial larynx characterized by comprising:
a neck-band is arranged at the upper part of the neck-band,
an excitation generating circuit portion mounted at one end of the neck strap,
an electric-force converting part installed at the other end of the neck strap,
a control switch which is wirelessly connected with the excitation generating circuit in a Bluetooth mode,
wherein:
the control switch comprises a mechanical switch button, a microprocessor and a first Bluetooth module, the mechanical switch button generates a control signal when a user presses the mechanical switch button, the control signal is transmitted to the excitation generating circuit through the first Bluetooth module, the second Bluetooth module and the third Bluetooth module,
the excitation generating circuit drives the electric-power conversion part to generate vibration to generate electronic artificial larynx voice,
the neck belt is internally provided with a battery for supplying power to the electronic artificial larynx device.
