Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a speaker device attached to the headrest of an automobile seat.

Prior Art and Problems In addition to car radios and car stereos, modern cars tend to be equipped with various wireless devices such as personal radios and special radios for road information, and the monitor speakers for these devices are installed in the headrests of the seats. It is considered to be installed. FIGS. 1 and 2 are first and second examples, in which 10 is the backrest of the driver's seat, 12 is a headrest, and 14 and 16 are small speakers with a monitor box. In FIG. 2, the speakers 14 and 16 are installed on both sides of the headrest, and the wiring is connected to the pair of supports 1 of the headrest.
It is carried out during the 8th and 20th. 22 and 24 are wiring terminals. In FIG. 2, a speaker mounting bracket 24 is installed between the pillars 18 and 20, and the speaker mounting bracket 24
Speakers 14, 1 are mounted on the pedestals 24a, 24b at both ends of the
6, and screws 26 and 28 are passed through the holes in the pedestal portion to fix the speaker. Wiring is done through the terminals on the back of the speaker box.

This speaker device works like a headphone for the listener, and since it is not attached to the head like a headphone, it is not bothersome and has an excellent design. In the speaker device shown in Figure 3, the headrest 12 is bent into a U-shape to accommodate the driver (listener).
The speakers 14 and 16 are attached to the inside of the bent end so as to surround the head 30 of the speaker. This type of device is functionally more similar to a headphone.

However, these proposed speaker devices have a fixed speaker, and there are various types of listeners, such as those with high sitting heights, those with low sitting heights, those with large heads, and those with small heads, so they have the disadvantage that they cannot be adapted to these types of listeners. Naturally, even when monitoring is not performed using a speaker, the previously proposed apparatus, particularly the apparatus shown in FIG. 3, has headrest bent portions 12a and 12b close to both sides of the head, and speakers are attached to these portions. This limits the driver's field of vision to above the chain line in Figure 3, and limits the range of movement of the driver's head to A1 and A2 in Figure 4.

Purpose of the invention The present invention aims to improve the above-mentioned problem that the optimal conditions cannot be obtained due to lack of compatibility with the user and usage conditions, and to provide a speaker device that can be adjusted to be optimal for the user. It is something to do.

Structure of the invention The present invention is a speaker device that is attached to the headrest of an automobile seat, in which the headrest is height-adjustably attached to the backrest of the seat, and both left and right ends of the headrest are attached to the center. Furthermore, the present invention is characterized in that speakers are attached to both end portions so as to be movable from side to side along the surfaces of the both end portions, which will be described below with reference to embodiments.

Embodiment of the invention As shown in FIG. 5, according to the invention, the speakers 14 and 16 are attached to a U-shaped headrest, and the base metal fitting 32 of this headrest has flexible arms 34 and 36 at both ends, which can be bent. The corners can be adjusted. FIG. 6 shows a state in which the bent portions 12a and 12b are opened and aligned with the central portion. The dotted line in FIG. 6 indicates a state bent into a U-shape. In addition, the speakers 14 and 16 are connected to the head rest base metal fittings 3.
It is movably attached to both ends 32a, 32b of 2.

FIG. 7 shows this moving mechanism, and 38 and 40 are speaker 14 and 16 mounting brackets that are slidably engaged with both ends 32a and 32b of the headrest base metal fittings, so that the positions of the speakers 14 and 16 are indicated by the arrows. Can move in the direction. In FIG. 8, a long groove 32c is provided at both ends 32b of the headrest base metal fitting, a threaded stud 44 of the speaker mounting metal fitting 38 is made to protrude from the long groove, and a thumbscrew 42 is screwed into the stud at the desired speaker position. Fix it. head rest 1
2 wraps the base metal fitting 32 with a cushion material such as urethane foam, and covers the surface with cloth, leather, etc.
The parts to which the parts are attached are exposed, excluding the cushion material. Also, some headrests are adjustable in height, but the present invention uses such a height-adjustable headrest. In this way, the height of the speakers 14 and 16 is adjustable, and the angle is that of both ends 32a and 32b relative to the center of the base metal fitting 32.
The angle formed by the two ends is adjustable, and the position of both ends 32 is adjustable.
A speaker device having three degrees of freedom in which the speaker positions on the speakers a and 32b are adjustable is obtained.

FIG. 10 shows a specific example of the present invention. The holes in the backrest part 10 fit loosely into the pillars 18 and 20 of the headrest 32, and they are fixed by a locking mechanism (not shown), so loosen the stopper, push in or pull out the pillars 18 and 20, and then lock the stopper. This allows the height of the headrest 12 to be adjusted as desired. By bending or stretching the headrest 12 at the flexible arms 34, 36, it becomes flat or U-shaped. Furthermore, the speaker position can be changed arbitrarily by moving the speaker on both ends 32a and 32b of the base metal fitting. In this way, according to the present invention, the speakers 14 and 16 can be placed at desired positions near the ears of listeners of various sitting heights and head sizes. Once the headrest is bent, both bent ends can be opened to form a flat plate, allowing the listener to concentrate on driving without being hindered by obstacles surrounding his or her head.

Effects of the invention As explained above, according to the invention, the condition of the headrest speaker can be optimized both when the listener concentrates on driving and when listening to the sound from the speaker for the purpose of listening to music or information gathering. It can be done. In addition, the positional relationship between the listener's ears and the speaker can be optimally adjusted to suit the listener, and the listener can enjoy good speaker sound.
