Each module or element may be omitted or modified as required, and there may not be other modules or elements between any two modules.

In an embodiment of the present invention, the tinnitus sound frequency obtaining module 21 is used to obtain the sound frequency f of the user's tinnitus sound. How to obtain the frequency of the user's tinnitus sound will be described in more detail below, so I won't repeat it here.

In an embodiment of the present invention, the sound generating module 23 is used to play a plurality of pure tones with a frequency within a frequency range during the playing time. The plurality of pure tones include a plurality of first pure tones and a plurality of second pure tones, the sound frequency f of the user's tinnitus and the plurality of first pure tones are located in the first frequency region, and the plurality of second pure tones are located in the second frequency region. The first frequency zone covers the X frequency range, 100 Hz≦X≦12000 Hz, and the second frequency zone is a part of the frequency range that does not include the first frequency zone. The multiple first pure tones account for M% of the multiple pure tones, where 50<M≦90, that is to say, the number of times the first pure tones are played is greater than that of the second pure tones. In a specific embodiment of the present invention, multiple pure tones are randomly generated, and the probability of the first pure tone is twice that of the second pure tone, but the present invention is not limited thereto. How the first frequency zone and the second frequency zone are determined in specific implementation will be described in more detail below, and will not be repeated here.

Next, please refer to FIG. 1 to FIG. 3 together. 2 is a flow chart of the steps of the method for producing sound for alleviating the impact of tinnitus according to the present invention; FIG. 3 is a schematic diagram showing the frequency ranges covered by the first frequency zone and the second frequency zone. The steps shown in FIG. 2 will be described below with reference to FIG. 1 and FIG. 3 . It should be noted that although the tinnitus blocker 1 disclosed in FIG. 1 is taken as an example below to illustrate the method for generating sound that alleviates the effect of tinnitus in the present invention, the method for generating sound that reduces the effect of tinnitus in the present invention is not the same as that used above. Structure of the tinnitus blocker 1 is limited.

First, go to step S1: acquire the sound frequency of the user's tinnitus sound.

This step can be accomplished with existing tinnitus tone matching procedures. The tinnitus sound frequency acquisition module 21 can control the speaker 10 to send a pure tone similar to the tinnitus intensity to users with tinnitus symptoms, and requires the user to press a specific (entity or virtual) button to input a specific signal. At this time, the tinnitus sound frequency acquisition module 21 will use the frequency of the last pure tone emitted before receiving the specific signal as the sound frequency f of the tinnitus sound.

Proceed to step S2: play a plurality of pure tones with a frequency within a frequency interval within a playing time, the plurality of pure tones include a plurality of first pure tones and a plurality of second pure tones, wherein the sound frequency of the tinnitus sound and the plurality of first pure tones are located at A first frequency zone, a plurality of second pure tones are located in a second frequency zone, the first frequency zone covers the X frequency range, 100 Hz≦X≦12000 Hz, and the second frequency zone is not included in the frequency range of the first frequency zone Partly, multiple first pure tones account for multiple pure tones M%, 50<M≦90.

After obtaining the sound frequency f of the user's tinnitus sound, the user can start to use the tinnitus masker 1 . When the user turns on the tinnitus masker 1 to use, the sound generating module 23 will control the speaker 10 to play a plurality of pure tones with a frequency within a frequency range within a playing time. The multiple pure tones include multiple first pure tones and multiple second pure tones. A plurality of first pure tones and the sound frequency f of the user's tinnitus will be located in a first frequency region, and a plurality of second pure tones will be located in a second frequency region, the first frequency region covers the X frequency range, 100 Hz≦ X≦12000 Hz, and the second frequency zone is a part of the frequency interval not including the first frequency zone. Multiple first pure tones account for multiple pure tones M%, wherein 50<M≦90. In an embodiment of the present invention, the frequency range covered by the first frequency zone is dynamic. More specifically, the frequency band and bandwidth covered by the first frequency zone will vary depending on the frequency f of the user's tinnitus. ,described as follows.

In an embodiment of the present invention, when the obtained sound frequency f is F Hz, the sound generation module 23 will use the frequency range of 0.25F-4F Hz as the frequency interval mentioned above, and will use the frequency range of 0.5F-2F The frequency range of Hertz is regarded as the first frequency zone, and the second frequency zone is the part of the frequency zone not including the first frequency zone, that is, two frequency ranges of 0.25F-0.5F Hz and 2F-4F Hz are included. Taking the example shown in FIG. 3 , assuming that the sound frequency f obtained from the user’s tinnitus is 1760 Hz, the sound generating module 23 will use the frequency range of 440-7040 Hz as the frequency interval, and the frequency range of 880-3520 Hz As the first frequency region 30 , the frequency ranges of 440-880 Hz and 3520-7040 Hz are used as the second frequency region 40 . The sound generation module 23 will control the loudspeaker 10 to randomly play a plurality of pure tones whose frequencies are located in the frequency range, and the pure tone (ie, the first pure tone) located in the first frequency zone 30 has a probability of producing about the same as the pure tone located in the second frequency zone 40 (ie, the first pure tone). two pure tones), that is, the number of times the first pure tone is played will be greater than the number of times that the second pure tone is played.

In an embodiment of the present invention, the frequencies of the plurality of pure tones emitted by the sound generating module 23 conform to twelve equal law. And, a plurality of pure tones located in the same octave interval are chord inner tones of the same chord, that is, a plurality of second pure tones located in the frequency range of 0.25F Hz to 0.5F Hz are chord inner tones of the same chord, located at 0.5 Multiple first pure tones in the frequency range of F Hz to F Hz are chord inner tones of the same chord, and multiple first pure tones in the frequency range of F Hz to 2F Hz are chord inner tones of the same chord, located in 2F Hz to 4F The plurality of second pure tones in the frequency range of Hertz are inner tones of the same chord, so that the played pure tones can have musicality, so that users can have a better hearing experience.

It can be seen from the previous disclosure that the method for producing sound that slows down the impact of tinnitus and the tinnitus masker 1 of the present invention can not only play pure tones with frequencies close to the frequency of tinnitus, but also play other pure tones with dissimilar frequencies. According to human experiments, only a small volume can effectively relieve tinnitus symptoms. In addition, the method for producing sound for alleviating the impact of tinnitus and the tinnitus masker 1 of the present invention can make the generated pure sound have a musical auditory effect, providing better auditory experience for tinnitus sufferers.

It should be noted that the above implementations are only examples of preferred embodiments of the present invention, and all possible combinations of changes are not described in detail to avoid redundant description. However, those skilled in the art should understand that not all the above-mentioned modules or elements are necessary. And in order to implement the present invention, other more detailed existing modules or components may also be included. Each module or element may be omitted or modified as required, and there may not be other modules or elements between any two modules. As long as it does not deviate from the basic framework of the present invention, it should be within the scope of rights claimed by this patent, and the scope of the patent application should prevail.
