Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a speaker box mounting device capable of detaching a speaker box from a cabinet such as a television receiver.

(B) Conventional Technology Conventionally, as a speaker box mounting device of this type, there is one disclosed in, for example, Japanese Utility Model Laid-Open No. 58-164385.

This is a speaker box that is detachably attached to an exhaust hole of a handle portion provided on a side surface of a television body by using an attachment fitting.

However, in the case of the above-mentioned conventional example, when the speaker is attached, the external appearance is inferior, and in the detached state of the speaker, the management of the mounting bracket is troublesome.

Further, in the one disclosed in Japanese Utility Model Laid-Open No. 58-59272, since the image part and the speaker part are completely separated from each other, there is a limitation in the speaker arrangement for making a sound.
Placing the speaker behind the user causes a drawback that the image and the sound are unnaturally separated from each other.

(C) Problems to be solved by the present invention The present invention has been made in view of the drawbacks of the above-mentioned conventional example, and the speaker can be arranged in various directions and positions without spoiling the appearance, and the speaker can meet the user's preference. It is an object of the present invention to provide a speaker box mounting device capable of producing sound.

(D) Means for Solving the Problems A first side surface that is adjacent to the rear surface at a constant acute angle and includes a first speaker, and a second side surface that is adjacent to the rear surface at substantially the same angle as the constant acute angle. A speaker box, a voice outlet that faces outward from the front of the cabinet on the front, and an opening on the back, and the first side face or the second side face of the speaker box corresponds to the voice outlet from the opening. Accordingly, the present invention provides a speaker box mounting device including a storage part for storing the speaker box and a second speaker fixed to the cabinet body.

(E) Action As described above, since the orientation of the speaker box can be changed in the storage section provided in the cabinet, the direction of the speaker can be changed without changing the shape of the cabinet, and even if the speaker box is removed, The speaker fixed to the cabinet allows sound to be heard from the side of the cabinet.

(F) Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. 3A and 3B are a front perspective view and a rear perspective view, respectively, of the speaker box of this embodiment. The speaker box (1) is a rectangular prism having a trapezoidal cross section composed of an upper surface, a lower surface (1a) (1b), front and rear surfaces (1c) (1d), first and second side surfaces (1e) (1f). Are doing Also, the first
A full-range speaker (2) is attached to the side surface (1e), and a cord (4) is attached to the recess (3) of the rear surface (1d).

FIGS. 4 (a) and 4 (b) are a front perspective view and a rear perspective view, respectively, of the cabinet of the large television receiver of this embodiment. Front side surfaces (6) (6) facing outward from the front surface of the cathode ray tube on both sides of the cabinet (5), respectively.
And rear side surfaces (7) and (7) facing outward from the rear surface of the cabinet (5). A tweeter-type speaker (8) that emits high frequencies is provided on the front side surface (6).
And a woofer-type speaker (9) that emits a low tone are fixed, and a fully breathable net (10) is attached to the front surface of the speaker. The speaker (8) faces in the same direction as the front surface of the cathode ray tube, and the speaker (9) faces in the same direction as the front side surface (6), and both the speakers (8) and (9).
Covers the entire range.

Further, an opening of a speaker housing recess (housing part) (11) having the same shape as the speaker box (1) and a slightly larger size than the speaker box (1) is formed in the upper portion of the rear side surface (7), and the housing recess ( The surface corresponding to the first and second side surfaces (1e) and (1f) of 11) is parallel to the front side surface (6) and is provided with a voice output port. Incidentally, (12) and (12) are winding pieces for winding the cord (4).

When the speaker box (1) is housed and mounted in the housing recess (11) so that the speaker (2) faces forward as shown in FIGS. 1 (a) and (b), the sound becomes as shown in FIG. 5 (a). It is emitted only in front of the cabinet (5) as shown.

As shown in FIG. 2, the speaker box (1) is rotated by 180 ° so that the upper surface (1a) is located at the lower side and the lower surface (1b) is located at the upper side, so that the speaker (2) becomes the cabinet (5). When the speaker box (1) is housed and mounted in the housing recess (11) so as to be located on the rear side surface (7), the speaker (8) fixed to the cabinet (5) as shown in FIG. 5 (b). ) (9) emits sound to the front, and the speaker (2) of the speaker box (1) emits sound to the rear. The sound emitted backward is reflected by the wall (13) and reaches the viewer. Since this sound is reflected by the wall (13), a phase delay occurs as compared with the sound emitted in front, and the acoustic effect is improved.

Further, the speaker box (1) can be removed from the cabinet (5), and if the speaker box (1) is arranged behind the viewer as shown in FIG. 5 (c), the viewer can see the cabinet (5). ), The sound from the speakers (8) and (9) fixed to (4) and the sound from the speaker (2) of the speaker box (1) can be listened to.

Further, the volume of the speaker (2) of the speaker box (1) can be controlled on the main body side of the television receiver separately from the volume of the speakers (8) and (9) fixed to the cabinet (5). It is also possible to intentionally add a phase difference to the sound from the speaker (2) to improve the acoustic effect, and both of the phase differences can be adjusted on the receiver main body side.

In the television receiver using the speaker box mounting device as described above, the speaker box (1) is vertically
By rotating and moving it by 0 ° and storing and mounting it in the speaker storage recess (11), it is possible to selectively emit sound to both the front and the rear, and remove the speaker box (1) from the cabinet (5). It can also be arranged. In addition, a speaker (8) is separately provided for the cabinet (5).
Since the (9) is attached, the speakers (2) and (8) do not become unnaturally separated from the image and the sound.
Various acoustic effects can be obtained by the arrangement combination of (9). Further, the speaker box (1) is housed in the storage recess (11) regardless of whether the speaker (2) is directed forward or backward, and the storage recess (11) is located behind the cabinet (5). Even if the speaker box (1) is removed, the opening is not visible and the appearance is not spoiled.

Since the television receiver of this embodiment is large,
Since the speaker box (1) is not moved so much, the lock mechanism for preventing the speaker box (1) from coming off the speaker housing recess (11) is not provided for the reason of reducing the number of parts as much as possible, but it is often moved. When the above-mentioned speaker box mounting device is used in a small television receiver, a lock mechanism for preventing the speaker box from coming off is provided in the speaker accommodating recess to improve usability.

(G) Effect of the invention According to the invention, a simple structure can be used without damaging the appearance.
It is possible to change the arrangement of the speaker box, and even if the speaker box is removed from the cabinet, a fixed speaker is attached to the cabinet, so that the image and the sound are unnaturally separated. It is possible to provide a speaker box mounting device capable of preventing the noise and making sound according to the taste of the user.
