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 reproduction device 2 and the volume control device 3 are provided separately, the volume control device 3 may be installed in the sound reproduction device 2 so that the two 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, etc.). When the sound reproduction device 2 and the volume control device 3 are provided as a single device, the functions of both can be installed on the same circuit board, or the programs of both can be executed by the same CPU, so it can be easily implemented 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 in accordance with the sound reduction signal AS. In this example,...

Deformed example 2）

[0062] In the above embodiment, in order to easily implement the volume reduction process, the volume is reduced in the entire frequency range of the reproduced sound, but it is not limited to this. In other words, the volume may be reduced only in a part of the frequency range (volume reduction range) of the reproduced sound. At this time, the volume reduction process can be implemented by a circuit that combines a filter and an electronic volume. In addition, the volume reduction process can also be implemented by installing a program with FIR (Finite Impulse Response) filter function or 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, that is, if the frequency difference caused by the masker (ie, reproduced sound) increases, the sound pressure decreases. Generally, in the impact sound, since the frequency compo...

Deformed example 3）

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

Abstract

The invention provides a sound volume control apparatus for adjusting volume of regeneration sound of a sound regeneration apparatus. The sound volume control apparatus has an operation sensor (for example, an acceleration sensor) which is arranged on a user's setting part and is used for detecting the user's predetermined operation. A volume control unit is provided to adjust the sound volume based on the output from the operation sensor. For example, detecting upper-and-lower brassie conversion action, reducing the volume of regeneration sound, so that users can hear clash generated when a brassie head stricks a golf, namely, the volume control unit restricts the volume of regeneration sound in setting time, so that the clash can't be shielded by the regeneration sound. The sound volume is adjusted according to specific frequency band.

Description

Technical field [0001] The present invention relates to a volume control device for controlling the volume of reproduced sound of a sound reproducing device, particularly a volume control for controlling the volume of reproduced sound when a user is listening to the reproduced sound while performing body exercise or sports competition Device. Background technique [0002] In recent years, it has become more and more popular for sports enthusiasts or sports athletes to carry portable sound reproduction devices while listening to music while enjoying sports or concentrating on sports competitions. This tendency can also be seen in many sports players. For example, golfers can also relax mentally by listening to music using a portable sound reproduction device, and can easily swing a golf club to play golf. Focus. Therefore, many golfers can be seen in golf driving ranges and others while listening to music through portable sound reproduction devices while practicing golf club swi...
