Problems solved by technology

In addition, golfers feel the pleasure through the impact sound from a proper shot. If the impact sound cannot be heard, they cannot feel the pleasure even if they hit the ball properly.
[0005] Although Patent Documents 1 and 2 perform music reproduction and volume control according to the user's motion, they do not take into account that the user also listens to other sounds (for example, golf club heads and other sounds) during the music reproduction process. the impact of golf balls) needs
Therefore, Patent Documents 1 and 2 do not consider the fact that other sounds are covered by music due to the characteristics of human hearing.

Deformed example 1

[0060] Although in the above-mentioned embodiment, the sound reproducing device 2 and the volume control device 3 are provided separately, the volume control device 3 may also be installed in the sound reproducing device 2 so that both become a single device. That is, an application software that realizes the function of the volume control device 3 may be installed on a device having an acceleration sensor and a sound reproduction function (for example, a smartphone or the like). When the sound reproduction device 2 and the volume control device 3 are set as a single device, since the functions of the two can be mounted on the same circuit board, or the programs of the two can be executed by the same CPU, it can also be easily realized. The volume adjustment control unit 324 outputs the sound reduction signal AS to the sound reproduction unit 22 , and the sound reproduction unit 22 adjusts the volume of the reproduced sound according to the sound reduction signal AS. In this e...

Deformed example 2）

[0062] In the above-described embodiments, the volume is lowered in the entire frequency range of the reproduced sound in order to easily implement the volume lowering process, but the present invention is not limited thereto. That is, the volume may be reduced only in a part of the frequency range (volume reduction range) of the reproduced sound. In this case, the volume reduction process can be implemented by a circuit combining a filter and an electronic volume. In addition, volume reduction processing can also be implemented by installing a program with a FIR (Finite Impulse Response) filter function or a DSP (Digital Signal Processor).

[0063] At this time, the volume reduction range is determined in consideration of the frequency components of the impact sound and the frequency characteristics of the masking level such that the sound pressure decreases if the frequency difference caused by the masker (ie, reproduced sound) increases. Generally, in the impact sound, sin...

Deformed example 3）

[0069] In the above-mentioned embodiment, the acceleration sensor 34 equipped on the waist of the user detects the up-and-down swing movement during the swing of the golf club, but the present invention is not limited thereto. It is also possible to use various sensors (for example, motion sensors) that can be equipped on a predetermined part of the user to detect the up-down swing movement during the swing of the golf club. For example, an acceleration sensor or an angle sensor that can be equipped on the user's upper wrist or wrist can be utilized. Alternatively, a pressure sensor that can be equipped on a golf glove in the user's palm can be used.

Abstract

PROBLEM TO BE SOLVED: To provide technologies for preventing sound generated by the motion of a user from being masked by other sound. SOLUTION: The user 1 wears a sound reproducer 2 and a volume controller 3 integrated with the sound reproducer 2 on the waist, and practices golf while listening to the sound output from a headphone 4 connected to the volume controller 3. A volume adjusting part 32 of the volume controller 3 adjusts the volume of the sound reproduced during a subsequent downward swing motion, on the basis of an output from an acceleration sensor 34 for detecting the user's turning motion from the top. The user can listen to the impact sound generated when a golf ball is hit. COPYRIGHT: (C)2013,JPO&INPIT

Description

technical field [0001] The present invention relates to a volume control device for controlling the volume of the reproduced sound of a sound reproduction device, especially a volume control device for controlling the volume of the reproduced sound when the user performs physical exercise or sports competition while listening to the reproduced sound device. Background technique [0002] In recent years, it has become more and more popular for sports enthusiasts or sports players to carry portable sound reproduction devices while enjoying sports or concentrating on sports while listening to music. This tendency can also be seen in many sports personnel. For example, golfers can also relax mentally by using portable sound reproduction devices to listen to music, and can easily play golf while swinging golf clubs. Focus. Therefore, it can be seen that many golfers practice golf swing while listening to music through a portable sound reproduction device at a golf driving range...
