Embodiment approach 1

[0032] [1-1. Overall composition]

[0033] The audio signal processing device according to Embodiment 1 will be described. In this embodiment, for example, audio content such as music recorded on a CD (Compact Disc) etc. is provided to the passenger seated in the passenger seat with a good volume balance, and the driver's ear is alerted. Audio content for alarm tones etc. Hereinafter, the audio signal processing device according to this embodiment will be described with reference to the drawings.

[0034] figure 1 It is a block diagram showing a schematic configuration of the audio signal processing device 100 according to this embodiment.

[0035] The audio signal processing device 100 is a device that processes first audio content and second audio content. The audio signal processing device 100 is used in vehicles such as automobiles, for example.

[0036] The first audio content includes a first left signal and a first right signal, and is processed to be reproduced a...

Embodiment approach 2

[0075] Next, an audio signal processing device according to Embodiment 2 will be described. The audio signal processing device according to this embodiment is similar to the audio signal processing device according to Embodiment 1 in processing the third audio content and amplifying and attenuating the first audio content in addition to the first audio content and the second audio content. Devices are different. Hereinafter, the audio signal processing device according to the present embodiment will be described with reference to the drawings focusing on differences from the audio signal processing device 100 according to Embodiment 1. FIG.

[0076] [2-1. Overall composition]

[0077] Figure 4 It is a block diagram showing a schematic configuration of the audio signal processing device 200 according to this embodiment.

[0078] The audio signal processing device 200 according to this embodiment is a device that processes the first to third audio contents. The first audio ...

Embodiment approach 3

[0098] Next, an audio signal processing device according to Embodiment 3 will be described. The audio signal processing device according to the present embodiment differs from the audio signal processing device 200 according to the second embodiment in that it can amplify the first audio content and does not necessarily process the third audio content. Hereinafter, the audio signal processing device according to this embodiment will be described with reference to the drawings, focusing on differences from the audio signal processing device 200 according to Embodiment 2. FIG.

[0099] [3-1. Overall composition]

[0100] Figure 5 It is a block diagram showing a schematic configuration of the audio signal processing device 300 according to this embodiment.

[0101] The audio signal processing device 300 according to this embodiment is a device for processing first audio content and second audio content. The first audio content and the second audio content are the same as the ...

Abstract

This audio signal processing device (100) is provided with: a first amplifying unit (10) which amplifies first audio content; a mixing unit (11) which mixes an output signal from the first amplifyingunit (10) with second audio content; a second amplifying unit (12) which amplifies an output signal from the mixing unit (11); and a setting unit (14) which sets an amplification amount of the first amplifying unit (10). The setting unit (14) sets the amplification amount of the first amplifying unit (10) such that the amplification amount of the first amplifying unit (10) offsets the amplification amount of the second amplifying unit (12).

Description

technical field [0001] The present disclosure relates to an audio signal processing device that processes a plurality of audio contents. Background technique [0002] In recent years, due to the advancement of ADAS (Advanced Driving Assistant System: Advanced Driving Assistance System) technology, it can automatically detect the dangers that drivers of vehicles such as pedestrians and motorcycles should pay attention to and avoid, and can put these dangers Communicated to the driver by voice message. In this case, if the driver can hear the warning message from the direction where the dangerous object exists, the driver's attention to the dangerous object can be further increased. For example, when a dangerous object is on the driver's right side, the driver's right ear is warned. Figure 6 It is a diagram of a method of effectively conveying a caution warning message to the driver 61 of the vehicle 50 . Such as Figure 6 As shown, for the driver 61 driving in the driver's...
