[Detailed description of the invention] Recently, the number of cars equipped with audio equipment is increasing, but mounting of the speaker in the car cabin is often problematic in terms of method and place. Since a speaker box can not be installed on a large scale in a vehicle interior limited in space, usually, as shown in FIG. 5, a speaker is often attached to a rear tray of a car. In this case, since the speaker is mounted upward, it is emitted at a right angle to the detractor, and the acoustic effect is significantly reduced. Fig. 2 is a sectional view of a coaxial type 2-unissic force attached to a rear tray of a car. 11 is a car rear tray board, 21 is a speaker mounting grille, 31 is a woofer-speaker frame, 41 how-far cone paper, 5 'heat tweeter speaker frame, 61 is tweet cone paper. The woofer and the tweeter are connected and fixed by a nonmagnetic material 17. A wire mesh 141 is attached to the front of the speaker. Heretofore, such a coaxial type 2-way speaker has been mounted upward on the board of the rear tray. From the viewpoint of sound effects, although the bass range is not so severe in the position and direction of the speakers, the positional relationship between the listener and the loudspeakers is very important for the middle and high tones. For example, when the speaker is attached upward as in the conventional example of FIGS. 5 and 6, the high range attenuates the low range, and the sound effect is significantly reduced. In the case of stereo sound, in particular, if the treble range 03-05-2019 1 is insufficient, the sound spreads and the feeling of presence is lacking and there is a fatal problem that the sound deviates from the Hi-Fi directivity. The present invention has been made to solve the above-mentioned drawbacks. The embodiments will be described in detail with reference to the drawings. In FIGS. 1, 2 and 3, 1 is a board of a rear tray of a car, and in particular, a speaker mounting grill 2 is fixed. A woofer-speaker 3 is attached to the inside of the speaker attachment grille 2. The tweeter speaker 5 is housed in the mounting boxes 7 and 13. A wire mesh 15 is attached to the front of the tweeter speaker 5. A pillar 8 is provided from the mounting box 7. A cylinder 9 is T-shaped at the tip of the pillar 8 Is formed. A plurality of grooves 10 are formed on the outer periphery of the cylinder 9, and the cylindrical portion 9 is held between the bearing portion 15 provided on a part of the speaker mounting grille 2 and the mounting piece 11 and fixed by screws 12. Thus, the tweeter speaker 5 is configured to be rotatable around the support point of the speaker mounting grille. Since the projection 16 is provided on the inside of the mounting piece 11, it is possible to add a moderation to the rotation of the tweeter 5 where the projection 16 matches the groove 10 of the cylinder . The lead wire of the Chi tweeter speaker 6 is connected to the woofer-speaker 3 through the column 8 and the cylinder 9; 4 to prevent the lead wire from being seen from the outside. Although the wire mesh 14 is attached to the front of the woofer-speaker 3, the wire mesh 14 is recessed so that the tweeter portion, the mounting boxes 7 and 13 for storing the speaker 6 and the support 8 do not hit. In this case, it is needless to say that the wire mesh 14 does not hit the cone paper 4 of the woofer-speaker 3. In actual use in such a speaker device, the tweeter speaker 5 can be raised to a device substantially perpendicular to the mounting surface of the woofer-speaker 3 as shown in FIG. As described above, when the tweeter speaker 5 listens in a state of facing the listener, the sound is transmitted directly to the listener as compared with the case of upward, so that it is possible to hear efficiently with less attenuation. If you want to attenuate the high range slightly depending on the preference, source, place, etc. of the listener, the tweeter speaker 5 may be slightly inclined, or it should be completely laid (horizontally placed). There is also a feature that it can be heard with any sound quality. In some cases, the tweeter speaker 5 can be completely laid back and stored when loading luggage on the board 1 of the rear tray, etc. There is no need to Further, as shown in FIG. 4, in the case of a rear tray with a strong structure such as a light van or a hatchback type car, the tweeter portions are attached forward when mounted on both sides of the vehicle interior. A speaker system with a good sound effect will be obtained. It can be used not only as a car speaker system but also as a home speaker system. That is, according to the above-mentioned embodiment, even if the speaker box is laid sideways, if the tweeter portion is erected, there is an effect that it is possible to listen to the high sound range efficiently. Still, by configuring the tweeter portion to freely rotate as in the embodiment, one novel design can be realized, and a product 6 having high appeal in design can be manufactured. As described above, according to the speaker device of the present invention, the tweeter portion can be made substantially orthogonal to a part of the woofer according to the embodiment of the present invention, and it is practically possible to 03-05-2019 2 take various forms and obtain desired acoustic effects. Excellent effects can be expected. 03-05-2019 3
