The invention will be described in detail below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1, an embodiment of the present invention provides a mobile terminal, including: a transducing unit 1, a sound wave encoding and decoding unit 2, and a central processing unit 3;

At least one

The acoustic wave codec unit 2 is connected to the transducing unit 1 and the central processing unit 3, respectively, configured to convert the analog electrical signal from the transducing unit 1 into a digital electrical signal and transmit it to the central processing unit 3;

The central processing unit 3, connected to the acoustic codec unit 2, is configured to process the digital electrical signals from the acoustic codec unit 2.

In the mobile terminal provided by the embodiment of the present invention, the transducing unit 1 can convert any one of an ultrasonic signal, an infrasound signal and an audible wave acoustic signal into an analog electric signal, and the analog electric signal can pass through the acoustic wave encoding and decoding unit 2 After encoding and analog-to-digital conversion, it is processed by the central processing unit 3 to form a series of digital electrical signals, thereby realizing conversion between three types of acoustic signals and electrical signals on mobile terminals such as ordinary mobile phones, tablets or personal digital assistants. It provides convenience for the application of ultrasonic and infrasound waves.

Since the transducing unit 1 is responsible for the conversion between the three acoustic signals and the electrical signals, in order to enable the sound conversion of each frequency band to be successfully completed, in a specific embodiment, the transducing unit 1 may include an ultrasonic transducer and a secondary acoustic transducer. The energy transducer and the audible wave transducer are three types of transducers. Preferably, each type of transducer may also include a different frequency response portion. For example, the ultrasonic transducer can be a piezoelectric ceramic of various frequency response characteristics, the audible wave transducer can be a microphone, and the infrasound transducer can be a capacitive infrasonic wave sensor or the like. These ultrasonic transducers, infrasound transducers, and audible wave transducers can be connected to the sonic codec unit 2 via a multiplexer, thereby enabling multi-way switching The control realizes the conversion of acoustic signals in different frequency bands.

The acoustic codec unit 2 is capable of converting an analog electrical signal into a digital electrical signal for central processing unit 3 to perform digital signal processing.

Specifically, the central processing unit 3 can perform various processes on the digital electrical signals transmitted from the acoustic wave decoding unit 2 to learn various characteristics of the acoustic signals corresponding to the digital electrical signals. For example, in one embodiment of the invention, the central processing unit 3 may be configured to process the digital electrical signals from the acoustic codec unit 2 to obtain amplitude and phase characteristics of the digital electrical signals.

The frequency characteristics are displayed so that the user can study the characteristics and laws of the object that emits ultrasound or infrasound more deeply. For example, using the infrasound generated by the aurora, the law of auroral activity can be studied; the position and size of the sound source can be detected by using the received infrasound generated by the measured sound source. In addition, many catastrophic natural phenomena, such as volcanic eruptions, tornadoes, typhoons, etc., may radiate infrasound waves before they occur, and these infrasound precursors can also be used to predict and predict the occurrence of these disastrous natural events. Certain organs of humans and other organisms also emit weak infrasound waves. By measuring the infrasound waves emitted by these organs, it is also possible to understand the activities of the corresponding organs of the human body or other organisms.
