Description

  The present application belongs to the technical field of speaker units, speaker devices, and speaker systems used in various acoustic devices.

  In recent years, with the reduction in the thickness of video display devices, the speaker device is also required to be thin, and as a result, a small high-performance speaker device is required. Moreover, since the enclosure of the speaker device has recently been molded from synthetic resin, the degree of freedom in the shape of the enclosure has increased. Further, in recent speaker devices, it is desired to reduce the number of parts in order to improve productivity and reduce cost.

  As shown in FIG. 1, a conventional speaker device 1 includes an enclosure 2 formed into a rectangular box shape using wood or the like, a baffle plate 4 that constitutes one side surface of the enclosure 2 and has a sound emitting hole 3 formed thereon, And a speaker unit 5 fixed so as to cover the sound emitting hole 3 of the baffle plate 4. The speaker unit 5 has a frame 6 made of metal or the like, and the speaker unit 5 is fixed to the baffle plate 4 by tightening the frame 6 and the baffle plate 4 in the vicinity of the sound emission hole 3 with a plurality of mounting screws 7. is doing.

  On the other hand, speaker devices attached to thin televisions such as PDP (Plasma Display Panel) and LCD (Liquid Crystal Display) are required to have various installation layouts. Such speaker devices are thin and thin. Therefore, the bass reproduction capability is insufficient. Further, since the speaker device uses resonance of the space portion of the speaker stand, it may be acoustically coupled to the speaker stand.

Conventionally, a speaker device acoustically coupled to a speaker stand is disclosed in Patent Document 1. In this speaker device, a square-shaped through hole is formed at a substantially central position of the bottom plate of the speaker box, and the upper end portion of the speaker stand is inserted into the square-shaped through hole so that the speaker device is acoustically connected to the speaker stand. Is bound to.

  Incidentally, in the conventional speaker device 1 shown in FIG. 1, the speaker unit 5 is attached to the baffle plate 4 by a plurality of mounting screws 7, and the speaker unit 5 is fixed by the plurality of mounting screws 7 in this way. Therefore, the stress is very concentrated on the mounting portion of the mounting screw 7, and this stress concentration appears as a curved distortion of the frame 6 as shown in FIG.

  This distortion of the frame 6 generates a gap S between the frame 6 and the baffle plate 4, causing a reduction in the airtightness of the baffle plate 4. As described above, when the airtightness of the baffle plate 4 is lowered, the bass reproduction performance is lowered and the sound quality is lowered due to the generation of irregular vibrations in the gap S. In addition, the distortion of the frame 6 causes the divided vibration of the frame 6 to deteriorate the sound quality, and also causes a reduction in the acoustic energy conversion efficiency of the electric energy applied to the speaker unit 5, resulting in a decrease in speaker efficiency. is there.

  On the other hand, in the invention disclosed in Patent Document 1, when the speaker device is attached to the speaker stand, a mounting screw is necessary, and the acoustic energy of the speaker device is taken into the space of the speaker stand to reinforce the bass. However, there is a problem in that air leakage occurs from the connecting portion between the speaker device and the speaker stand, lowering the bass reproduction capability, and lowering the sound quality due to the occurrence of irregular vibration in the gap.

  The present application has been made in consideration of the above-described circumstances, and an example of the problem is a speaker unit, a speaker device, and a speaker system that enable a speaker component to be detachably sealed and coupled to prevent air leakage from the coupling portion. Is to provide.

  In order to solve the above-mentioned problem, the speaker unit according to claim 1 is characterized in that a speaker frame is provided with a coupling portion that is detachably sealed with respect to the coupled portion provided in the sound emitting hole of the enclosure. .

  According to a second aspect of the present invention, there is provided a speaker device comprising: an enclosure in which a coupled portion is provided in a sound emitting hole; and a speaker unit in which a coupled portion that is detachably sealed to the coupled portion is provided in a speaker frame. And

  According to a sixth aspect of the present invention, there is provided a speaker device comprising: an enclosure in which a sound emission hole is formed; a coupling means that is inserted from the sound emission hole of the enclosure and has one of a male screw portion and a female screw portion; A speaker unit in which the other of the male screw portion and the female screw portion is engraved along the inner or outer peripheral surface of the speaker frame, the coupling means is screwed into the speaker frame, and the enclosure and the speaker frame Are hermetically bonded.

  A speaker system according to a seventh aspect is characterized in that a coupled portion is provided in one speaker constituent member, and a coupling portion that detachably seals the coupled portion is provided in the other speaker constituent member.

  Embodiments of a speaker device and a speaker system according to the present application will be described with reference to the drawings.

(First Embodiment of Speaker Device)
First, the configuration of the speaker device according to the first embodiment will be described with reference to FIGS. 3 and 4. 3 is a cross-sectional view showing the speaker device before fixing the speaker unit in the first embodiment, and FIG. 4 is a cross-sectional view showing the speaker device after fixing the speaker unit in the first embodiment. 3 and 4, the enclosure is shown in cross section, but the speaker unit is shown in a plane.

  As shown in FIG. 3, the speaker device 10 includes an enclosure 13 in which a baffle plate 12 having a circular sound emitting hole 11 formed at a substantially central position is integrally formed so as to constitute one side surface, and the enclosure 13 And a speaker unit 14 that is coupled and mounted so as to cover the sound emission hole 11.

  The enclosure 13 is formed from a synthetic resin such as ABS resin into a square hollow box shape, and a female screw portion 11 a as a coupled portion is engraved on the inner peripheral surface of the sound emitting hole 11.

  Similarly to the enclosure 13, the speaker unit 14 has a frame 15 formed from a synthetic resin such as ABS resin. The speaker unit 14 can be attached to and detached from the female threaded portion 11 a of the enclosure 13 at a stepped portion on the back side in the sound emission direction of the frame 15. A male screw portion 15a is engraved as a coupling portion that is hermetically sealed and screwed together.
