Description

  The present invention relates to a speaker.

  In-vehicle speakers are usually mounted on a plurality of parts such as an inner surface of a front door and an inner surface of a rear door. Even if the plurality of in-vehicle speakers attached to these parts have the same size (for example, a diameter of 16 cm) and the same shape, types such as grades may be different.

As described above, when in-vehicle speakers having the same size and shape and different grades are attached to the vehicle, it is necessary to identify the in-vehicle speakers. Conventionally, an identification structure for changing the color of a cushion provided on the front surface of a vehicle-mounted speaker frame (the surface on the inner side of the vehicle when mounted) or an identification structure for providing a marking on the front surface of the frame is known.

  However, the conventional speaker identification structure that changes the color of the cushion has a problem that the types of colors that can be used for the cushion are limited, and the types of speakers that can be identified are also limited. In addition, in the speaker identification structure in which the marking is provided on the front surface of the frame, it is necessary to take out the vehicle-mounted speaker from the packing box and check the marking on the front surface of the frame, which is troublesome. With the marking on the front, when the speaker is stood in a packing box, only the side of the speaker can be seen even when the box is viewed from above, and the front of the speaker cannot be confirmed. Such a problem occurs not only in a vehicle-mounted speaker but also in various speakers.

  The present invention has been made in view of such problems, and provides a speaker that can identify various types of speakers with a simple configuration, and that can be identified by simply opening the lid of the box without removing the speaker from the packaging box. Is an issue.

The present invention employs the following means in order to solve the above problems.
That is, the present invention
In a speaker having a sound generator and a frame surrounding the outer periphery of the sound generator,
A rib-shaped or groove-shaped identifying means is provided on the outer peripheral surface of the frame.

  According to the present invention, the configuration can be simplified because only the rib-shaped or groove-shaped identifying means is provided on the outer peripheral surface of the frame. Further, by packing the outer peripheral surface of the speaker and the identification means toward the lid of the packing box, the identification means can be visually recognized only by opening the lid.

  Here, a connector may be provided on the outer peripheral surface of the frame, and the identification unit may be provided on both sides of the connector in the circumferential direction of the outer peripheral surface. In this case, since the identification means is provided at two places with a gap, even when one of the identification means is hidden by the cord connected to the connector when the speaker is attached to a vehicle or the like, for example. The other identification means can be visually recognized, and thereby the type of speaker can be determined.

  In addition, a flange for attachment may be provided, and the identification means may be provided on the front surface of the flange.

  Moreover, the said identification means can be set as the structure arrange | positioned substantially parallel with respect to the center axis line of the said flame | frame. The identification means may be configured to identify the type of the speaker according to the number.

  As described above, according to the present invention, various types of speakers can be identified with a simple configuration. For example, the speaker can be identified simply by opening the lid of the packaging box.
