The microcomputer 15 controls each component of the audio device, and when a user requests volume adjustment of the audio played through the key input unit 17, a corresponding control signal is transmitted to the volume control unit 12. To pass.

In addition, the microcomputer 15 collects the volume level selected by the user, the duration of the volume level, and the like, and uses the volume usage information such as the number of times of use of each volume level (frequency) and the cumulative duration of each volume level. It is processed and stored in the memory 16. In this case, if the volume usage information is sufficiently collected, a volume section preferred by the user is determined based on the volume usage information, and a volume step is set differently for each volume level or section to set the volume adjusting unit 12 based on this. To control.

The memory 16 stores basic volume intervals in which the intervals between the initially set volume levels are constant, and the information generated by the microcomputer 15, that is, the number of times each volume level is used and the accumulation of each volume level. It additionally stores volume usage information such as duration, user preferred volume section, and changed volume interval.

First, in the audio volume level adjusting method according to the present invention, for example, as shown in FIG. 3, in the microcomputer 15 of an audio device such as a car audio or the like, information related to a volume selected by a user when playing an audio signal is shown. In step S10, for example, the volume level selected by the user, the duration of the volume level, and the like are collected and processed into the number of times of use of each volume level (frequency), the cumulative duration of each volume level, and the like. 16). At this time, only the volume level that has been used for a predetermined time or more should be collected as valid volume information.

The microcomputer 15 checks whether the volume information has been sufficiently collected (S11), and adjusts the volume of the reproduced audio signal by applying a default volume setting value while not enough data is collected. The memory 16 The default volume setting value in which the interval between each volume level is set is stored.

When it is determined that the volume information has been sufficiently collected, the microcomputer 15 determines a volume section preferred by the user based on the volume usage information managed in the memory 16, and sets the volume interval for each volume level or The adjusted volume interval is adjusted differently for each section and stored in the memory 16 (S12).

For example, the microcomputer 15 searches for a section in which the number of times of use or a cumulative duration of each volume level is greater than or equal to a predetermined reference value, and determines the user's preferred volume section. As shown in FIG. The volume interval, which is the interval between the volume levels in the user preferred volume section, is fine and the volume interval in the other volume section is widened. The volume interval in the other volume section is set to the original basic volume as shown in FIG. 5. You can use the value as it is.

In the latter case, each volume interval is stored in the memory 16 in order of a new volume setting value, from the smallest volume level value (Volume 0) to the largest volume level value (Volume 40), or each volume. Level values may be stored in sequence.

Alternatively, as in the previous example, the volume interval is different from the volume level with the highest frequency of use or the volume level with the longest cumulative duration in the user preferred volume section, but the volume interval is constant in other volume sections. You may.

Thereafter, when the user selects the user preferred volume mode through the key input unit 17 (S13), the microcomputer 15 reads out a new volume setting value managed in the memory 16. At this time, when the volume up or volume down command is input from the user, the microcomputer 15 checks the current volume control section (S14), and if the identified volume control section is a user preferred volume section (S15), the memory A control signal corresponding to the user preferred volume section of the new volume setting value read out from (16) is applied to the volume adjusting unit 12 (S16).

In addition, as a result of checking the current volume control section in the microcomputer 15, when the volume is another volume section other than the user preferred volume section, a control signal corresponding to the basic volume setting value managed in the memory 16 is outputted to the volume. The control unit 12 is applied (S17).

Further, even when the volume of the audio is adjusted in the user preferred volume mode, the microcomputer 15 collects information related to the volume selected by the user, that is, the volume level, the duration of the volume level, and the like, and processes the same. In the memory 16, the volume setting value to be used in the user preferred volume mode may be continuously updated based on the memory 16.

As described above, the user preference volume section may be determined based on the accumulated volume usage information, or may be selected by the user in another way. That is, the user may select two volume level values on the boundary of the user preferred volume section, so that the volume interval in the selected user preferred volume section is different from the volume interval in the other volume section.

It is an illustration.

First, in the audio volume level adjusting method according to another embodiment of the present invention, for example, as shown in FIG. 6, a user selects a user preferred volume mode through the key input unit 17 of the audio device. In the state in which the preferred volume mode is set (S20), when a specific key (Fast Key) is input through the key input unit 17 according to a user's request (S21), the microcomputer 15 determines the current volume control section. Check (S22).

When the checked volume control section is identified as a user preferred volume section (S23), the microcomputer 15 reads a basic volume setting value managed from the memory 16, and outputs a corresponding control signal to the volume control section. Applies to (12), and changes the volume interval of the user preferred volume section as shown in Figure 7 (S24).

In addition, as a result of confirming the current volume control section in the microcomputer 15, in the case of a volume section other than the user preferred volume section, the basic volume setting value managed in the memory 16 is read out and correspondingly. A control signal is applied to the volume adjusting unit 12, and as shown in FIG. 7, the volume interval of the other volume section is maintained at the current setting state or the basic volume setting value read out from the memory 16 is read. By changing the setting to be wider, a control signal corresponding thereto is applied to the volume adjusting unit 12, and the volume interval of another volume section is changed and set as shown in FIG. 8 (S25).

As described above, according to the present invention, when a specific key is input in a state in which a user preferred volume mode is set in an audio device such as car audio, the present volume control section is checked by checking a current volume control section. If the user's preferred volume section is set to change the volume interval to the default volume interval to adjust the volume of the audio, and if the current volume control section is the default volume section, the volume interval is set to the currently set default volume interval You can adjust the volume of the audio by adjusting the volume or changing the volume interval to be wider than the default volume interval.
