Abstract

PURPOSE: A sound wave generating method of a mobile communication terminal is provided to create a relaxation mood by outputting a sound wave data stored in a memory. CONSTITUTION: A microprocessor stores a sound wave data obtained by suitably mating an alpha wave, a theta wave and a delta wave to a relaxation mode, a sleep mode and a mind-concentration mode according to a sound wave generation program in a memory(S1,S2). When a user manipulates a key pad and outputs a key signal to select one of the relaxation mode, the sleep mode and the mind-concentration mode, the microprocessor recognizes the input key signal, reads a corresponding sound wave data of the selected mode, and transfers it to a sound generator(S3-S7). The sound generator converts the sound wave data into a digital pulse stream and outputs it(S8). A booster amplifiers the digital pulse stream. A sound output unit outputs a sound(S10).

Description

Sound wave generation method of mobile communication terminal {ACOUSTIC WAVE GENERATION METHOD FOR MOBILE TELECOMMUNICATION TERMINAL EQUIPMENT}

The present invention relates to a technology for generating sound waves that help relaxation, sleep and mental concentration, and in particular, it can help to create a relaxing atmosphere, induce sleep, or improve concentration, which makes you feel free from various stresses. The present invention relates to a sound wave generating method of a mobile communication terminal suitable for providing a sound wave.

A sound generating technology of the conventional mobile communication terminal will be described with reference to FIGS. 1 and 2 as follows.

When the desired value is recorded in the registers of the M / N counters 11A and 11B, the signal F_ref of the reference frequency (for example, 307.5 KHz) to which the M / N counters 11A and 11B are input is clocked. The signal is used to generate a signal of the required frequency. The output signals of the M / N counters 11A and 11B and the signal F_ref of the reference frequency are AND-combined by the AND gates AD11, AD12, and AD13, and then the OA gate OR11. The digital pulse stream is combined into a single tone or a dual tone multiple frequency (DTMF).

The digital pulse stream output from the ringer generation circuit as shown in FIG. 1 is amplified by the booster 21 as shown in FIG. 2 and then output to the outside through the sound output unit 22.

However, in the mobile communication terminal according to the prior art, it is possible to simply output various types of buzzer sounds or music for notifying that an incoming call has been received, and thus it is simply an electronic device because it does not provide a service to help the user's life. There was a difficulty in ignorance.

Accordingly, an object of the present invention is to generate a sound wave of a mobile communication terminal that combines alpha waves, theta waves, and delta waves to create a relaxing atmosphere, to induce sleep, or to improve concentration. In providing a method.

As shown in FIG. 3, a keypad 31 for outputting a key signal for setting a sound wave generation mode of a user desired form and ; A microprocessor (MSM) 32 that reads sound wave data of a resting mode, a sleep mode or a concentrated mode from a memory 33 to be described later according to a key signal input from the keypad 31 and generates a corresponding sound; ; A memory 33 for storing sound wave data suitable for creating a comfortable relaxation atmosphere, sound wave data suitable for inducing sleep, and sound wave data that can help improve concentration; A booster (34) for amplifying the digital pulse stream output from the sound generator (32A) of the central processing unit (32) to a level suitable for outputting to the outside; The sound output unit 35 outputs the sound signal of the base band output from the booster 34 to the outside, and will be described in detail with reference to FIG. 4 attached to the operation of the present invention.

The study of sound in the modern sense began in earnest in the mid-1930s, and scientists found that the electrical signals of the brain had a habit of assimilation from regular external stimuli of sound. Dr. Gray Walter, a British neurologist, found that sound acts on brain waves and induces deep physical relaxation and a vibrant mental state.

The human brain emits electric current in the process of processing information received from external sensory organs, called brain waves. The types of brain waves are divided into alpha waves, beta waves, and theta waves, depending on the frequency. 12 Hz) and theta waves (4 7 Hz) is a low frequency brain brain that is closely related to the exercise of memory, creativity, and learning ability, and is primarily a beta wave (13) in high arousal levels, such as when excited or nervous. 30Hz) and delta wave (1) during sleep 3 Hz)

Accordingly, the present invention stores the sound wave data in which the alpha wave, theta wave and the delta wave are appropriately set for the resting mode, the sleep mode, and the mental concentration mode in a storage medium, and reproduces and outputs the sound wave data of the corresponding mode according to the user's request. As one example, the processing thereof is as follows.

The microprocessor 32 stores, in the memory 13, sound wave data that is appropriately combined with the alpha wave, theta wave, and the delta wave in the resting mode, the sleep mode, and the mental concentration mode by the sound wave generation program (S1, S2).

In this state, when the user operates the keypad 31 to output a key signal for selecting any mode among the rest mode, the sleep mode, and the mental concentration mode, the microprocessor 32 recognizes the input key signal. The sound wave data is read from the sound wave data of the resting mode, the sleep mode, and the mental concentration mode stored in the memory 33 and transferred to the internal sound generator 32A. (S3-S7)

Accordingly, the sound generator 32A converts the input sound wave data of the corresponding mode into a digital pulse stream form and outputs the digital pulse stream to a level suitable for outputting the digital pulse stream to the outside by the booster 34. After the amplification process is output to the outside through the sound output unit 35, such as earphone. (S8-S10)

Therefore, the user can listen to the sound of the mode selected by the user through the earphone.

As described in detail above, the present invention stores sound wave data of a resting mode, a sleep mode, and a mental concentration mode in combination with an alpha wave, theta wave, and delta wave in a storage medium, and reproduces the sound wave data of the corresponding mode according to a user's request. By outputting, there is an effect that can create a relaxing atmosphere that makes you feel free from various stresses, induce sleep, or help improve concentration.
