(First embodiment)
Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a sound reproducing device 1 according to the first embodiment of the present invention.

  In FIG. 1, the sound reproduction device 1 includes an addition unit 101, a measurement unit 102, a control unit 103, a reception unit 104, and a notification unit 105, and inputs such as a sound source 2, operation buttons and / or a touch panel. It is connected to a device 3, a display device 4 such as a liquid crystal display, and a speaker 5.

  The adding unit 101 is configured by a plurality of sound effect adding units, stores information representing a valid, invalid, or unset state for each sound effect, and further, for an effective sound effect, its effect amount Is stored. Here, “effective” means that an acoustic effect is added to the acoustic signal from the sound source 2, “invalid” means that no acoustic effect is added to the acoustic signal, and “unset” means that the acoustic signal is not added. Indicates whether the sound effect is enabled or disabled for the signal. Further, the adding unit 101 performs a process of adding a sound effect to the sound signal from the sound source 2 under the control of the control unit 103, and outputs the sound signal to the speaker 5.

  The measurement unit 102 measures, for example, a reproduction time as the reproduction amount of the acoustic signal to which the acoustic effect is added. In addition, the measurement unit 102 stores the amount of reproduction measured at the time when reproduction is stopped due to temporary stop or power off, and continues measurement after resumption of reproduction.

  The control unit 103 controls each unit constituting the sound reproduction device 1.

  The accepting unit 104 acquires information input to the input device 3 by the user and transmits the acquired information to the control unit 103.

  The notification unit 105 displays various information on the display device 4 under the control of the control unit 103.

  The operation of the sound reproducing device 1 configured as described above will be described with reference to FIG. Note that the sound reproduction device 1 starts the following operation while the sound signal output from the sound source 2 is being reproduced.

  First, the control unit 103 controls the adding unit 101 to forcibly add an unset sound effect to the sound signal regardless of the user's selection, and the sound signal to which the sound effect is added is transmitted to the speaker 5. (S11).

  Next, measurement of the reproduction time T is started by the measurement unit 102 (S12).

  When the reproduction time T measured by the measuring unit 102 is equal to or longer than the predetermined time T1 (YES in S13), the acoustic effect is added to the acoustic signal reproduced in step S11 and information about the acoustic effect ( For example, the description of the acoustic effect) is displayed on the display device 4 by the notification unit 105 (S14).

  Next, information for inquiring the user about whether to enable or disable the acoustic effect in the future and the effect amount in the case of enabling the sound effect is displayed on the display device 4 by the notification unit 105, and the user inputs the input device 3. Is received by the receiving unit 104 (S15).

  When the information indicating the effect of the sound effect and the effect amount is transmitted from the reception unit 104 (YES in S16), the adding unit 101 is controlled by the control unit 103, and the sound effect is transmitted with the transmitted effect amount. Is added to the audio signal from the speaker 5 (S17).

  On the other hand, when information representing that the acoustic effect is invalidated is transmitted from the receiving unit 104 (NO in S16), the adding unit 101 is controlled by the control unit 103, and an acoustic signal to which the acoustic effect is not added is transmitted to the speaker 5. (S18).

  In the above operation, the predetermined time T1 is a time that is considered sufficient for the user to feel the effect for each sound effect. Meanwhile, in the case of an acoustic effect that is easy to feel the effect, it is determined in advance such as 3 days.

  Such an acoustic reproduction device 1 allows the user to unknowingly experience the acoustic effect for a predetermined reproduction time, and then notifies the user of information regarding the experienced acoustic effect to effectively make the acoustic effect effective. Let the user choose whether to disable or enable. As a result, the sound reproduction apparatus 1 allows a user who is not interested in the sound effect to experience the sound effect for a predetermined reproduction time and easily understand the explanation of the sound effect, and to deepen interest in the sound effect. The possibility that the acoustic effect is used can be increased.

  In the present embodiment, the measurement unit 102 measures the reproduction time as the reproduction amount of the acoustic signal to which the acoustic effect is added, but represents how much the user has experienced the acoustic effect. If there is, the reproduction amount may be measured using another scale. For example, the reproduction amount may be the number of reproductions of the acoustic signal to which the acoustic effect is added. Specifically, the measurement unit 102 may measure the number of music breaks represented by the acoustic signal after the acoustic signal to which the acoustic effect is added is reproduced as a reproduction amount. In this case, the sound reproducing device 1 starts measuring the number of times C of song separation in step S12 in FIG. 2, and determines in step S13 whether the number C is equal to or greater than the predetermined number C1.

  Here, the predetermined number of times C1 is the number of times considered to be sufficient for the user to feel the effect for each sound effect. For example, in the case of a sound effect that is difficult to feel, the effect is felt 30 times. In the case of an easy sound effect, it is predetermined such as 5 times.

  The sound reproducing apparatus 1 configured as described above adds a sound effect to various music pieces until a predetermined number of music pieces is reached, thereby allowing the user to apply the sound effect only to a specific music piece. Can be prevented from having a biased and bad impression. As a result, the sound reproducing device 1 can make the user experience the sound effect without giving a biased bad impression even to a user who is not interested in the sound effect, and can increase the possibility that the sound effect is used. it can.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  FIG. 3 is a block diagram showing the configuration of the sound reproducing device 10 according to the second embodiment of the present invention. In FIG. 3, the sound reproduction device 10 is different from the above-described sound reproduction device 1 in that a measurement unit 1020 is provided instead of the measurement unit 102. Regarding other configurations, there is no difference between the sound reproducing apparatuses 1 and 10. Therefore, in FIG. 3, the same reference numerals are assigned to the components corresponding to the configuration shown in FIG. 1, and the descriptions thereof are omitted.

  The measurement unit 1020 measures the elapsed time t after the effect amount of the acoustic effect is changed, in addition to the reproduction time T of the acoustic signal after the acoustic effect is added.

  The operation of the sound reproducing device 10 configured as described above will be described with reference to FIG. In FIG. 4, steps that operate in the same manner as the sound reproducing device 1 are denoted by the same reference numerals and description thereof is omitted. In addition, the sound reproducing device 10 starts the following operation while the sound signal output from the sound source 2 is being reproduced.

  First, the control unit 103 controls the adding unit 101 to add an unset sound effect to the sound signal with the minimum effect amount, and the sound signal to which the sound effect is added is reproduced from the speaker 5 (S21). .

  Next, measurement of the reproduction time T and the elapsed time t is started by the measurement unit 1020 (S22).

  Next, when the reproduction time T measured by the measurement unit 1020 becomes equal to or longer than the predetermined time T1 (YES in S13), the sound reproduction device 10 operates in the same manner as the sound reproduction device 1 from step S14 to S18.

  On the other hand, when the reproduction time T measured by the measuring unit 1020 is less than the predetermined time T1 (NO in S13), the control unit 103 determines whether or not the elapsed time t is equal to or longer than the predetermined time T2 (S23). ).

  When it is determined that the elapsed time t is equal to or longer than the predetermined time T2, the control unit 103 determines whether or not the current effect amount is less than the specified value M (S24).

  When it is determined that the current effect amount is less than the specified value M, the control unit 103 controls the adding unit 101 so that the effect amount of the sound effect added to the sound signal is increased by a predetermined value. At the same time, the measurement of the elapsed time t is started again from zero by the measuring unit 1020 (S25).

  Here, T2 is determined in advance such that the effect amount reaches the specified value M from the minimum value at time T1. That is, from the minimum effect amount to the specified value M, the user can set the effect amount step by step for each sound effect. If the number of steps is N, T2 is determined by the following equation (1). .

T2 = T1 / (N-1) (1)
Such a sound reproducing device 10 increases the effect amount stepwise when adding an unset sound effect to the sound signal, so that the user can experience the sound effect without a sense of incongruity. As a result, users who are not interested in the sound effect can select whether to enable or disable the sound effect after experiencing the sound effect without feeling uncomfortable, and the sound effect can be used. Sexuality can be increased.

  Note that, as with the measurement unit 102 in the first embodiment, the measurement unit 1020 represents the amount of reproduction using a measure other than the reproduction time as long as it represents how much the user has experienced the acoustic effect. You may measure. For example, the measurement unit 1020 may measure the number of music breaks represented by the acoustic signal as the reproduction amount after the acoustic signal to which the acoustic effect is added is reproduced.

  As described above, the sound reproducing device and the integrated circuit according to the present invention have the effect that the possibility of using the sound effect can be increased even for a user who is not interested in the sound effect. Useful as.
