Problems solved by technology

[0004] Since existing sound output systems output sound based on a predetermined relationship between volume levels and sound output, conventional sound output systems cannot meet the needs of users for precise volume control, such as music experts who are sensitive to small changes in sound output

Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0023] figure 2 is a block diagram illustrating one embodiment of a volume control device according to the present invention. refer to figure 2 , the volume control device includes an instruction and information input unit 201 , a system control unit 202 , a memory 203 , and a sound output unit 204 .

[0024] The instruction and information input unit 201 inputs sound increase / decrease interval information desired by the user, or volume level information selected by the user, and volume control signals generated using volume control keys (+ / -).

[0025] If the instruction and information input unit 201 inputs the sound increase / decrease interval information, the system control unit 202 uses the preset minimum sound increase / decrease interval information MIN INTERVAL and the maximum sound increase / decrease interval information MAX INTERVAL to d...

Abstract

A volume control apparatus and a method enable the volume of sound output from a sound output system to be adjusted in units of an increase / decrease interval set by a user, the volume control apparatus controlling the volume of sound output from the sound output system on a basis of volume level information set by the user. The volume control apparatus includes a memory in which sound increase / decrease interval information which a user wants is stored, a command and information input unit that inputs the sound increase / decrease interval information and a volume control signal with respect to sound output from the sound output system, a sound output unit that outputs sound generated in the sound output system to an outside of the volume control apparatus, and a system control unit that stores the sound increase / decrease interval information input from the command and information input unit in the memory and controls the sound output unit such that sound output from the sound output unit is increased / decreased a basis of the sound increase / decrease interval information stored in the memory when the volume control signal is received.

Description

technical field [0001] The invention relates to a sound output system, in particular to a device and method for controlling the volume of output sound. Background technique [0002] figure 1 The general characteristics of the sound output from the sound output system are shown in . user pair figure 1 Changes in the sound output within the shown intervals (101) and (102) are insensitive. At this point, as figure 1 As shown in , a traditional sound output system is designed while considering the relationship between the volume level and the sound output so that the sound output varies linearly with the volume control. [0003] That is, in figure 1 In , the interval between S1 and S2, the time interval between S2 and S3, and the time interval between Sn-1 and Sn are the same. If the user increases the volume level from V1 to V2, the sound output level increases from S1 to S2, and if the user decreases the volume level from V3 to V2, the sound output level decreases from S...
