いう欠点があつた。 Conventionally, in a vehicle-mounted sound field correction device, a microphone for detecting a signal sound is installed at the front of the device body. Normally, sound field correction is performed to optimize the listening position, but when using conventional equipment in a car, there are restrictions on the mounting position of the main unit, such as under the dashboard of the passenger seat or in the console box. It is often installed in departments. FIG. 1 is a perspective view of such a conventional detection microphone device for a vehicle-mounted sound field correction device. 1 is the main body of the sound field correction device installed under the dashboard board, and the detection microphone 2 is built-in as shown. There is. Figure 2 is a frequency response curve showing an example of the correction characteristic. When the detection characteristic shown by the solid line 3 is obtained, if the correction is made to have the correction characteristic shown by the dotted line 5, the ideal characteristic 4 should be obtained. , 1st
If correction is performed using signals detected using a sound field correction device as shown in the figure, the actual listening position and acoustic conditions (such as the influence of surrounding reflected sounds) will be significantly different, so it is necessary to perform appropriate sound field correction. The drawback was that it was difficult to

れた音場補正を行なうことができる。 As shown in the figure, by integrally embedding one or more signal detection microphones in the headrest of a vehicle, effective sound field correction can be performed at the actual listening position. If a signal detection microphone is embedded in each headrest part of the vehicle interior and the correction characteristics of each part are recorded in the variable equalizer control part, music that is effectively corrected according to each listening position can be produced by switching. I can hear it. For example, by electrically processing the signals detected by the microphones 1 and 2, balanced sound field correction can be performed for the listening positions of both the front seats 5 and 6.
