Description

  The present invention relates to a speaker device that is mounted on a door of, for example, an automobile and has improved sound quality emitted from the speaker.

  For example, as shown in FIGS. 9 and 10, a speaker 130 is attached to an inner panel 171 of an automobile door. The door of the automobile includes an outer panel 191 made of a steel plate which is a panel 170 on the outdoor side of the automobile, an inner panel 171 made of a steel plate which is fitted to the outer panel 191 and is an inner panel 170 of the automobile, and an inner panel. A wood fiber-containing plate material 171 and a woven fabric door trim 150 (FIG. 9), so-called door lining 150, are installed on the indoor side of 171. A speaker 130 is attached to the inner panel 171.

  The speaker 130 converts an input electric signal into an acoustic signal and radiates it as a sound wave to the space. The speaker 130 includes a magnetic circuit unit 135 (FIG. 9) such as a magnet (not shown) or a voice coil (not shown), and a diaphragm 133 (FIG. 10) such as cone paper. . By vibrating the diaphragm 133 (FIG. 10) back and forth by the magnetic circuit unit 135 (FIG. 9), air is vibrated and sound is emitted from the speaker 130.

  The front-rear direction of the speaker 130 will be described. As shown in FIG. 10, the side on which the diaphragm 133 is provided is the front side 130 a or the front side 130 a of the speaker 130. Further, the side on which the magnetic circuit unit 135 (FIG. 9) for driving the diaphragm 133 of the speaker 130 is provided is the back side 130 b or the rear side 130 b of the speaker 130. Note that the definitions of “front”, “back”, and “front and rear” in this specification are for convenience in explaining the speaker.

  The state when sound is emitted from the speaker 130 will be described. Sound is emitted from the front and rear of the speaker 130 by the operation of the front and rear of the diaphragm 133 provided in the speaker 130. When the diaphragm 133 of the speaker 130 is moved back and forth to generate a dense wave, a sound is emitted from the speaker 130. Sounds emitted before and after the speaker 130 when the speaker 130 is driven are the same sound with opposite phases.

  In order to enjoy music with high sound quality in an automobile, it is important to prepare an environment around the speaker 130 that is a sound generation source. For example, if the board that separates the front and rear of the speaker is omitted and the surroundings of the speaker are not maintained, the sounds before and after the speakers will cancel each other out, and the bass generated by the speakers is difficult to hear It will be a thing.

  As shown in FIGS. 9 and 10, in most vehicles, the door speaker 130 is incorporated in the inner panel 171 of the door, so that the door panel 170 itself functions as an enclosure that improves the sound of the speaker 130. It is supposed to be. An enclosure means what surrounds the speaker 130. Examples of the enclosure include a box surrounding a speaker.

  In order to further improve the sound quality in the vehicle, as shown in FIG. 10, service holes 175A, 175B, 175C, and 175D opened in the door panel 170 are closed with vibration-proof materials 185A, 185B, 185C, and 185D. ing. Further, in order to prevent the speaker 130 and the door panel 170 from being resonated when the speaker 130 attached to the door panel 170 is sounded at a high volume or when it is sounded at a heavy bass. As shown in FIG. 9, the inner baffle board 110 is incorporated between the speaker 130 and the door panel 170. The inner baffle board 110 is a vibration absorbing member.

  As shown in FIGS. 9 and 10, the inner baffle board 110 corresponds to the speaker 130 assembled to the door inner panel 171, and can be attached to a door in which the speaker 130 is incorporated into the inner panel 171. It is said that.

  The sound quality emitted from the speaker 130 is improved by incorporating the inner baffle board 110 between the speaker 130 and the door panel 170. In this way, the sound quality inside the vehicle can be improved when the door speaker 130 is attached to the door panel 170.

  The baffle means a plate that blocks the front and back surfaces of the diaphragm 133. Baffle means that the sound emitted from the back surface of the diaphragm 133 turns around in front of the diaphragm 133 in the opposite phase, so that the normal phase sound and the opposite phase sound cancel each other and the sound quality deteriorates. It is intended to prevent. In addition, the baffle may mean a “table” for vibration suppression to which the speaker 130 is attached. Reference numeral 180 denotes an inside handle 180 used when the door of the automobile is opened and closed.

  Incidentally, in the case where the door speaker is incorporated in the door trim 50 (substitute in FIG. 6), it is difficult to improve the sound quality. FIG. 6 shows a state in which the trim 50 in which the speaker is not attached is viewed from the back side. In order to improve the sound quality in the car, for example, a hole (not shown) is newly opened in the recess (73) corresponding to the speaker of the inner panel (71) (substitute in FIG. 8) constituting the door, When a speaker is incorporated in the hole, there is a concern that water leakage may occur in the vehicle through the hole or that rust is generated on the inner panel (71) of the door.

  Further, when sound is produced from the speaker mounted on the door trim (50) (substitute in FIG. 6), the sound is emitted from the front and rear of the speaker due to the operation toward the front and rear of the diaphragm of the speaker. The noises tend to wrap around each other at the door trim (50). Therefore, both sounds generated from the front and back of the speaker collide with each other and cancel each other. In addition, in the speaker attached to the door trim (50), since there is no enclosure that functions as a speaker box, sound is diffused to the rear side of the speaker. For these reasons, the sound emitted from the speaker mounted on the door trim (50) may be heard as a distorted sound or a muffled sound.

  Further, for example, when a speaker attached to the door trim (50) is played at a high volume or is played at a heavy bass, resonance may occur between the speaker and the door trim (50). . For these reasons, the speaker attached to the door trim (50) has not been able to fully exhibit the original performance of the speaker.

  The present invention has been made in view of such a situation, and an object of the present invention is to provide a speaker device with improved sound quality emitted from the speaker.

  In order to achieve the above object, a speaker device of the present invention includes a panel, a trim that is attached to the indoor side of the panel and has an opening corresponding to the front side of the speaker, and the panel and the trim. In the speaker device comprising the speaker mounted in between, a substantially cylindrical spacer extending from the speaker toward the panel is attached to the rear side of the speaker so that the rear side of the speaker is The spacer is surrounded by the panel (Claim 1).

  With this configuration, the rear side of the speaker is surrounded by the spacer and the panel, so that the sound emitted from the speaker is prevented from diffusing to the rear side of the speaker, and the sound emitted from the speaker is not It spreads from the front side of the speaker toward the front of the speaker. Therefore, the directionality of the sound is clarified, the sound quality is improved, and a bass is easily produced, so that a sound field full of a sense of reality is provided.

  Preferably, the spacer is provided with a seal member for preventing sound emitted from the speaker from being leaked from a gap between the spacer and the panel, and the seal member is in contact with the panel. 2).

  Thereby, the sound emitted from the speaker is further spread from the front side of the speaker toward the front of the speaker. Since the seal member provided in the spacer is in contact with the panel, sound is less likely to leak outside from the space behind the speaker formed by being surrounded by the spacer and the panel. Therefore, the sound emitted from the speaker is emitted toward the front side of the speaker, and the directionality of the sound is further clarified.

  It is preferable that the panel includes an inner panel constituting a door of an automobile, and the trim is formed as a door trim that covers the inner panel of the automobile.

  If a door provided with such a speaker device is assembled and used as an automobile door, it is possible to enjoy high-quality music in the automobile.

  According to the first aspect of the present invention, the directionality of sound is clarified, the sound quality is improved, and a low sound is easily produced, so that a sound field full of realism can be provided.

  According to the second aspect of the present invention, the sound emitted from the speaker is emitted toward the front side of the speaker, and the directionality of the sound can be further clarified.

  According to the invention described in claim 3, high-quality music can be enjoyed in the automobile.
