Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a car-mounted speaker that is attached to the inside of a car, for example, on the inner surface of a door.

[Technical background of the invention] In general, a car-mounted speaker has the following configuration. That is, a substantially conical frame is attached to the inner surface of a car door, and a low-to-midrange diaphragm (hereinafter referred to as a woofer) is attached concentrically to the expanding direction of the frame. A middle and high frequency range diaphragm (hereinafter referred to as a tweeter) is eccentrically mounted in the direction in which the woofer expands. Further, the tweeter is oriented in the same direction as the woofer, or is attached at an angle. If it is tilted, its position is fixed.

[Problems with the background art] However, with such a configuration, since the tweeter orientation is fixed in any case,
For example, when the tweeter was directed towards the driver's seat, people in the rear seats sometimes felt that the high-pitched sound was insufficient.

[Purpose of invention]

The present invention was developed based on the above points, and its purpose is to make it possible to appropriately change the direction of the tweeter in the direction of the occupants in the car, and to prevent situations where the occupants feel that the treble is insufficient. Our goal is to provide a car-mounted speaker that can be installed in a car.

[Summary of the idea]

In other words, the car-mounted speaker according to the present invention includes a substantially conical frame that is attached to an arbitrary position in the car, a woofer that is attached concentrically in the direction in which the frame expands, and a woofer that is attached in the direction in which the woofer expands. In a car-mounted speaker equipped with a tweeter attached eccentrically to the woofer, the tweeter is tilted at a predetermined angle with respect to the woofer, and the tweeter is made to revolve around the center of the woofer within a predetermined range. It is.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG. 1 is a front view of the speaker according to this embodiment, and reference numeral 1 in the figure indicates a frame. This frame 1 has a substantially conical shape and is attached to the inner surface of a car door 2. A woofer 3 is attached concentrically to the expanding direction (inside the vehicle) of the frame 1, and this woofer 3 also has a substantially conical shape. A grill 4 is attached to the outer periphery of the woofer 3 in the expansion direction. A rotating ring base 5 is attached to the inner circumference of the grille 4, and a tweeter 6 is mounted eccentrically on one side of the rotating ring base 5 (lower half position in Figure 2). It is attached. As is clear from FIG. 2, the tweeter 6 is mounted at a predetermined angle (for example, 30 degrees) with respect to the orientation of the woofer 3. The tweeter 6 is rotated at a predetermined angle (for example, 180 degrees) around the center of the woofer 3.
It is configured to rotate (revolution).

The rotational operation of the tweeter 6 will be explained below. That is, a gear portion 5A is formed on the inner half of the outer circumference of the rotary ring base 5 (upper half in FIG. 2), and a pinion 7 is formed in this gear portion 5A.
are meshing. This pinion 7 is integrated with a knob 9 via a shaft 8, and by operating this knob 9 from the outside of the grille 4, the tweeter 6 is activated.
It has a configuration that allows it to rotate within a 180 degree range. In the figure, reference numeral 12 indicates a damper, 13 indicates a holding ring, and 14 indicates a net.

The operation will be explained based on the above configuration. That is, the above-mentioned speaker is attached to the inner surface of the car door 2 near the bottom of the knob 9A, as shown in FIG. 4, for example. For example, if the driver 10 wants to hear better, the tweeter 6 is directed toward the driver 10 as shown by the broken line in FIG. As a result, the driver 10 can listen to music comfortably without feeling that the high-pitched sounds are insufficient as in the past. If the passenger 11 in the rear seat wants to hear the sound clearly, the tweeter 6 is rotated and directed toward the passenger 11 in the rear seat by operating the knob 9 as shown by the solid line in FIG. As a result, the passenger 11 in the rear seat can listen to music comfortably without feeling that the high-pitched sound is insufficient.

That is, the tweeter 6 is tilted at a predetermined angle (e.g., 30 degrees) with respect to the direction of the woofer 3, and at a predetermined angle (e.g., 180 degrees) around the center of the woofer 3.
Since it is rotated, it is possible to change the direction of the tweeter 6 to the optimal position according to the position of the occupants in the car, and the occupants will not feel the lack of high-pitched sounds as in the past, and will be in a comfortable state. I can listen to music.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the same effects as in the above-described embodiments can be obtained even if the woofer and tweeter are configured to be rotatable together through a grill (not shown). Further, in order to make the rotation of the rotation ring base 5 smooth, a roller may be interposed between the grille 4 and the rotation ring base 5.

[Effect of idea]

As described above in detail, the car speaker of the present invention is a car speaker comprising a substantially conical frame which can be attached at any position inside the car, a woofer which is attached concentrically in the direction of expansion of the frame, and a tweeter which is attached eccentrically in the direction of expansion of the woofer, the tweeter being inclined at a predetermined angle relative to the woofer,
The tweeter is configured to revolve around the center of the woofer within a predetermined range.

Therefore, the orientation of the tweeter can be changed appropriately according to the position of the occupant in the vehicle, and it is possible to provide the optimum condition for the occupant to listen to music.
