Conventionally, when assembling the speaker 18 in the head unit HY as described above, a space for arranging the control unit such as the display unit 19 and the operation unit 20 is left in the front panel 17. It was necessary, and the arrangement space of the speaker was limited.

When two speakers are provided for stereo reproduction, only extremely small speakers can be installed, and stereo reproduction is practically impossible. Furthermore,
Even if a diffuser, an equalizer, a high frequency speaker, or the like is installed on the front surface of the speaker 18, these have only individual functions, and the arrangement space of the speaker on the panel surface is not improved.

An object of the present invention is to solve the above-mentioned drawbacks of the related art, to effectively use the space for arranging the front panel of the head unit, and to provide a vehicle-mounted acoustic device capable of arranging a speaker on the entire panel surface. To provide.

[0007]

In order to achieve the above object, according to the present invention, one unit of a plurality of vehicle-mounted audio equipment units is mounted as a head unit on a center console of a vehicle and other units are mounted. In a vehicle-mounted audio device in which a control unit including an operation unit and the like are collectively arranged on a front panel section of the head unit, at least one speaker, preferably at least two or more for stereo reproduction, is provided on the front panel section. The speaker is arranged, and the control unit is mounted on the front surface of the speaker via a support member. Here, the control unit is an operation unit,
It includes a display unit, a remote control light receiving unit, a microphone, and the like.

In the above structure, the shape of the support member projecting from the yoke pole portion of the speaker may be a diffuser or an equalizer. Also,
As the control unit, in addition to the operation unit, the display unit, etc., a remote control light receiving unit or at least one or more microphones can be arranged, and the control unit is arranged so as to extend over two or more speakers. can do.

[0009]

Since one or a plurality of speakers are arranged on the front panel portion of the head unit, and the control portion such as the operation portion and the display portion is mounted on the front surface of the speaker through the supporting member, the head is constructed. The front panel portion of the unit does not require a space for arranging the control portion, and the speaker can be arranged on the entire front panel portion.

As a result, stereo reproduction can be performed by mounting the L channel and R channel speakers on the front panel of the head unit. That is, since a speaker having about half the size of the front panel can be installed, stereo reproduction can be sufficiently performed.

Further, if the shape of the support member is configured to be a diffuser or an equalizer, it is possible to control the spread and characteristics of the sound from the speaker, so that a desired sound field space can be reproduced, and the speaker can be installed in the center console. Since they can be arranged, the function as a center speaker for sound field reproduction can be provided, and the effect of front localization can be easily obtained. Also, by attaching a microphone to the display unit or the operation unit, it is possible to perform voice input and reverberation control in the vehicle interior.
