DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A speaker system according to one embodiment of the present disclosure comprises a housing having an opening, a partition plate dividing an internal space of the housing, a first speaker disposed in the internal space and having a front portion fixed to a first surface of the partition plate, and a second speaker disposed in the internal space and having a front portion fixed to a second surface of the partition plate opposite the first surface at a position different from that of the first speaker, wherein the housing has (i) a first space in which the first speaker is disposed, (ii) a second space in which the second speaker is disposed, and (iii) a third space including a first front space formed in front of the first speaker, a second front space formed in front of the second speaker, and a communicating space communicating with the first front space and the second front space, and the first speaker and the second speaker are driven in phase.

[0010] According to this, the front part of the first speaker and the front part of the second speaker are fixed to the first surface and the second surface, which are both surfaces of the partition plate, respectively, and the first speaker and the second speaker are driven in the same phase, so that the vibration transmitted from the first speaker to the partition plate and the vibration transmitted from the second speaker to the partition plate can be made to be in opposite phase. Therefore, the vibration transmitted from the first speaker and the vibration transmitted from the second speaker cancel each other out at the partition plate. Therefore, it is possible to reduce vibration of the housing of the speaker system and to reduce vibration transmitted to the structure on which the speaker system is installed.

[0011] The first speaker and the second speaker may be disposed at positions overlapping each other when one of the first speaker and the second speaker is viewed from the side.

[0012] This allows the housing of the speaker system to be made thinner.

[0013] The first speaker and the second speaker may be arranged to face in opposite directions to each other.

[0014] As a result, the first speaker and the second speaker are arranged in positions where they overlap each other on their respective sides, and thus the width of the housing of the speaker system in the front-to-rear direction of each speaker can be reduced while ensuring the volumes of the first space and the second space, making it possible to make the housing thinner.

[0015] The partition plate may also have a first plate to which the first speaker is fixed, a second plate that is approximately parallel to the first plate and located away from the first plate in a direction perpendicular to the first plate and to which the second speaker is fixed, and a connecting plate that is positioned between the first speaker and the second speaker and connects the first plate and the second plate.

[0016] Therefore, even in a configuration in which the first speaker and the second speaker are arranged facing in opposite directions and are arranged in overlapping positions on each side, the front of the first speaker and the front of the second speaker can be fixed to both sides of the partition plate.

[0017] The opening may communicate the third space with an external space of the housing.

[0018] Therefore, the sounds emitted from the first speaker and the second speaker can be effectively emitted from the housing.

[0019] The opening may be a slit.

[0020] This makes it possible to make the opening less noticeable.

[0021] The third space may have a volume in which a resonance frequency is set higher than a predetermined band to be used.

[0022] This effectively improves the quality of the sound emitted from the speaker system.

[0023] The device may further include a sound absorbing material disposed in the third space.

[0024] Therefore, the resonance frequency based on the third space can be adjusted, and the quality of the sound emitted from the speaker system can be effectively improved.

[0025] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A speaker system according to an embodiment of the present invention will now be described in detail with reference to the drawings.

[0026] Note that the embodiments described below each show a specific example of the present invention. The numerical values, shapes, materials, components, the arrangement and connection of the components, steps, and the order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, components that are not described in an independent claim showing a superordinate concept are described as optional components.

[0027] (Embodiment) The configuration of a speaker system according to an embodiment will be described.

[0028] FIG. 1 is a diagram showing an example of installation of a speaker system according to an embodiment.

[0029] As shown in Fig. 1, the speaker system 1 is installed in a state of being embedded in a wall 400 inside a room. An opening 401 is formed in the wall 400, and sound of the speaker system 1 is emitted from the opening 401 into the space inside the room. The opening 401 may be formed so as to overlap with an opening through which the speaker system 1 emits sound. The speaker system 1 may be embedded not only in the wall 400, but also in other building materials such as a ceiling or a floor. The surface on which the opening through which the speaker system 1 emits sound is provided may be covered by a building material such as a wall material, ceiling material, or floor material, or may form a surface of the indoor space such as a wall surface, ceiling surface, or floor surface.

[0030] Next, a specific configuration of the speaker system 1 will be described.

[0031] FIG. 2 is an external perspective view of the speaker system.

[0032] As shown in FIG. 2, the speaker system 1 includes a housing 10 having an opening 11, and a first speaker 21 and a second speaker 22 disposed in the internal space of the housing 10. The housing 10 has a flattened, generally rectangular parallelepiped shape with a width in the Y-axis direction smaller than its widths in the X-axis direction and Z-axis direction. The housing 10 is made of, for example, metal, resin, wood, or the like. In this embodiment, the X-axis direction is the front-rear direction, the Y-axis direction is the left-right direction, and the Z-axis direction is the up-down direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0033] Next, the internal space of the housing 10 of the speaker system 1 will be described.

[0034] FIG. 3 is a III-III cross-sectional view of the speaker system in FIG. 2 and FIG. 5. FIG. 4 is a IV-IV cross-sectional view of the speaker system in FIG. 2 and FIG. 5. FIG. 5 is a VV cross-sectional view of the speaker system in FIG. 2 and FIG. 3. The III-III cross-section is a plane parallel to the XY plane located at a position between the first speaker 21 and the second speaker 22 and the partition plate 33 as shown in FIG. 5. The IV-IV cross-section is a plane parallel to the XY plane passing through the opening 11 as shown in FIG. The VV cross-section is a plane parallel to the YZ plane passing through the partition plate 32 as shown in FIG. 3.

[0035] As shown in these figures, in the internal space of the housing 10, partition plates 12, 31 to 33 that divide the internal space, a first speaker 21 and a second speaker 22 are arranged.

[0036] The partition plate 12 divides the internal space of the housing 10 in the front-rear direction. The partition plate 12 is formed over a distance from the bottom surface of the housing 10 on the negative Z-axis direction side to a predetermined width in the Z-axis direction, and is disposed at a position away from the top surface of the housing 10 on the positive Z-axis direction side. In other words, the partition plate 12 has a predetermined height, which is shorter than the height of the internal space of the housing 10.

[0037] The partition plate 12 has a first plate 12a to which the first speaker 21 is fixed, a second plate 12b to which the second speaker 22 is fixed, and a connecting plate 12c that connects the first plate 12a and the second plate 12b. The first plate 12a and the second plate 12b are arranged, for example, parallel to the YZ plane. The first plate 12a and the second plate 12b are arranged at different positions in the X-axis direction. That is, the first plate 12a and the second plate 12b are arranged at positions separated from each other in the X-axis direction. The first plate 12a and the second plate 12b are also arranged at different positions in the Y-axis direction. The connecting plate 12c is arranged between the first plate 12a and the second plate 12b in the X-axis direction, and is fixed to an end of the first plate 12a on the positive side of the Y-axis and an end of the second plate 12b on the negative side of the Y-axis. That is, the first plate 12a, the second plate 12b and the connecting plate 12c are integrally formed in a stepped shape. The connecting plate 12c is disposed between the first speaker 21 and the second speaker 22 in the Y-axis direction.

[0038] The partition plate 31 further divides the space on the negative X-axis direction side of the partition plate 12 in the left-right direction. The partition plate 31 is disposed, for example, parallel to the XZ plane. Like the partition plate 12, the partition plate 31 is formed over a distance from the bottom surface on the negative Z-axis direction side of the housing 10 to a predetermined width in the Z-axis direction, and is disposed at a position away from the top surface on the positive Z-axis direction side of the housing 10. In other words, the partition plate 31 has a predetermined height.

[0039] The partition plate 32 further divides the space on the positive side of the X-axis of the partition plate 12 in the left-right direction. The partition plate 32 is arranged, for example, parallel to the XZ plane. Like the partition plates 12 and 31, the partition plate 32 is formed over a distance from the bottom surface on the negative side of the Z-axis of the housing 10 to a predetermined width in the Z-axis direction, and is arranged at a position away from the top surface on the positive side of the Z-axis of the housing 10. In other words, the partition plate 32 has a predetermined height.

[0040] Partition plate 33 vertically separates a space on the positive X-axis side of partition plate 12 and the negative Y-axis side of partition plate 32 from a space on the negative X-axis side of partition plate 12 and the positive Y-axis side of partition plate 32. Partition plate 33 is disposed, for example, parallel to the XY plane. Partition plate 33 is disposed at the end position of the positive Z-axis side of partition plates 12, 31, and 32 in the Z-axis direction.

[0041] The partition plates 12, 31 to 33 are made of, for example, metal, resin, wood, etc. The housing 10 and the partition plates 12, 31 to 33 may be made of the same material or different materials.

[0042] The internal space of the housing 10 is partitioned by partition plates 12, 31, 32, and 33 into a first space S10, a second space S20, and a third space S30. A first speaker 21 is disposed in the first space S10. The first space S10 is a closed space surrounded by the wall surface of the housing 10 and the partition plates 12, 32, and 33. The second space S20 is a closed space surrounded by the wall surface of the housing 10 and the partition plates 12, 31, and 33. The volume of the first space S10 and the volume of the second space S20 may be equal to each other.

[0043] The third space S30 includes a first front space S31, a second front space S32, and a communication space S33. The first front space S31 is a space on the negative X-axis side of the first plate 12a of the partition plate 12 and on the negative Y-axis side of the partition plate 31. The second front space S32 is a space on the positive X-axis side of the second plate 12b of the partition plate 12 and on the positive Y-axis side of the partition plate 32. The communication space S33 is a space on the positive Z-axis side of the partition plate 33. The communication space S33 communicates with the first front space S31 and the second front space S32. Therefore, the first front space S31, the second front space S32, and the communication space S33 constitute one third space S30 that communicate with each other. The volume of the first front space S31 and the volume of the second front space S32 may be equal to each other.

[0044] The third space S30 has a volume in which a resonant frequency is set higher than a predetermined band to be used in the speaker system 1. Therefore, the resonant frequency in the third space S30 can be set to a range outside the predetermined band to be used, and the quality of the sound emitted from the speaker system 1 can be effectively improved.

[0045] The first speaker 21 is fixed to the first surface 13 on the positive X-axis side of the partition plate 12, with the front of the first speaker 21 facing the negative X-axis side. The first speaker 21 is fixed to the partition plate 12 in a position where the front of the first speaker 21 faces the negative X-axis side. The first speaker 21 is fixed to the first plate 12a of the partition plate 12. An opening 12aa is formed in the first plate 12a, and the first speaker 21 is fixed to the first plate 12a so that a diaphragm (not shown) of the first speaker 21 is exposed from the opening 12aa to the negative X-axis side. Therefore, the first speaker 21 is disposed in the first space S10, and emits sound toward the first front space S31. The first space S10 also functions as an enclosure for the first speaker 21. The front side of the first speaker 21 is, for example, the side on which the diaphragm of the first speaker 21 is arranged, and the rear side of the first speaker 21 is, for example, the side on which the magnetic circuit (not shown) of the first speaker 21 is arranged.

[0046] The second speaker 22 has a front portion fixed to the second surface 14 of the partition plate 12 on the negative X-axis direction side. The second surface 14 is the surface opposite to the first surface 13 of the partition plate 12. The second speaker 22 is fixed to the partition plate 12 with the front side of the second speaker 22 facing the positive X-axis direction side. The second speaker 22 is fixed to the second plate 12b of the partition plate 12. An opening 12ba is formed in the second plate 12b, and the second speaker 22 is fixed to the second plate 12b so that a diaphragm (not shown) of the second speaker 22 is exposed from the opening 12ba to the positive X-axis direction side. Therefore, the second speaker 22 is disposed in the second space S20 and emits sound toward the second front space S32. Therefore, the second space S20 functions as an enclosure for the second speaker 22. The front side of the second speaker 22 is, for example, the side on which the diaphragm of the second speaker 22 is arranged, and the rear side of the second speaker 22 is, for example, the side on which the magnetic circuit (not shown) of the second speaker 22 is arranged.

[0047] The first speaker 21 and the second speaker 22 are disposed at positions where they overlap each other when viewed from the side (i.e., in the Y-axis direction). Moreover, since the front part of the first speaker 21 is fixed to the first surface 13 of the partition plate 12 and the front part of the second speaker 22 is fixed to the second surface 14 of the partition plate 12, the first speaker 21 and the second speaker 22 are disposed facing in opposite directions. Moreover, the first speaker 21 and the second speaker 22 are disposed at different positions in the Y-axis direction and are disposed at positions where they do not overlap when viewed from the X-axis direction.

[0048] The opening 11 of the housing 10 communicates the third space S30 with the external space of the housing 10. Specifically, the opening 11 is formed on the Z-axis plus side of the partition plate 33, and communicates the communication space S33 of the third space S30 of the internal space of the housing 10 with the external space. The communication space S33 communicates with the first front space S31 from which the first speaker 21 emits sound and the second front space S32 from which the second speaker 22 emits sound, so that the sound from the first speaker 21 and the second speaker 22 is emitted from the opening 11. The opening 11 is, for example, a slit that is long in the Y-axis direction. Note that the opening 11 is not limited to a slit, and may be a plurality of holes arranged in the Y-axis direction, or may be an opening of another shape such as a circle, an ellipse, or a square.

[0049] FIG. 6 is a block diagram showing an example of the configuration of a speaker system.

[0050] The speaker system 1 includes a first speaker 21, a second speaker 22, and a control circuit .

[0051] The first speaker 21 and the second speaker 22 emit sound. The first speaker 21 and the second speaker 22 may be, for example, woofers. The first speaker 21 and the second speaker 22 may be, for example, full-range speakers. The first speaker 21 and the second speaker 22 are the same speaker.

[0052] The control circuit 40 drives the first speaker 21 and the second speaker 22 in phase (in-phase). The control circuit 40 outputs the same audio signal to the first speaker 21 and the second speaker 22.

[0053] According to the speaker system 1 of this embodiment, the front part of the first speaker 21 and the front part of the second speaker 22 are fixed to both sides of the partition plate 12, that is, the first surface 13 and the second surface 14, respectively, and the first speaker 21 and the second speaker 22 are driven in the same phase. Therefore, the vibration transmitted from the first speaker 21 to the partition plate 12 and the vibration transmitted from the second speaker 22 to the partition plate 12 can be made to be in opposite phase (opposite phase) to each other. As a result, the vibration transmitted from the first speaker 21 and the vibration transmitted from the second speaker 22 cancel each other out at the partition plate 12. Therefore, it is possible to reduce the vibration of the housing 10 of the speaker system 1, and to reduce the vibration transmitted to the structure on which the speaker system 1 is installed.

[0054] In addition, in the speaker system 1 according to the present embodiment, the first speaker 21 and the second speaker 22 are disposed at positions where they overlap each other when viewed from the side. This allows the housing 10 of the speaker system 1 to be made thinner.

[0055] In addition, in the speaker system 1 according to the present embodiment, the first speaker 21 and the second speaker 22 are arranged facing in opposite directions. Therefore, the first speaker 21 and the second speaker 22 are arranged in positions where they overlap each other on their respective sides. This makes it possible to reduce the width of the speakers 21, 22 in the front-rear direction of the housing 10 of the speaker system 1 while ensuring the volumes of the first space S10 and the second space S20, and thus makes it possible to make the housing 10 thinner.

[0056] In the speaker system 1 according to this embodiment, the partition plate 12 has a first plate 12a, a second plate 12b, and a connecting plate 12c. The first speaker 21 is fixed to the first plate 12a. The second plate 12b is substantially parallel to the first plate 12a, is spaced apart in a direction perpendicular to the first plate 12a, and has the second speaker 22 fixed thereto. The connecting plate 12c is disposed between the first speaker 21 and the second speaker 22, and connects the first plate 12a and the second plate 12b.

[0057] Therefore, even in a configuration in which the first speaker 21 and the second speaker 22 are arranged facing in opposite directions and are arranged in positions overlapping each other on their respective sides, the front of the first speaker 21 and the front of the second speaker 22 can be fixed to both sides of the partition plate 12, i.e., the first surface 13 and the second surface 14, respectively.

[0058] In the speaker system 1 according to the present embodiment, the opening 11 communicates the third space S30 with the space outside the housing 10. Therefore, the sounds emitted from the first speaker 21 and the second speaker 22 can be effectively emitted from the housing 10.

[0059] In addition, in the speaker system 1 according to the present embodiment, the opening 11 is a slit, which makes it possible to make the opening 11 less noticeable.

[0060] (Variation 1) In the speaker system 1 according to the embodiment described above, the partition plate 12 has a stepped shape, but the shape is not limited to this and may be a flat plate.

[0061] Fig. 7 is a cross-sectional view of the speaker system according to the first modification, corresponding to the cross-sectional views taken along line III-III in Fig. 2 and Fig. 5. Fig. 8 is a cross-sectional view of the speaker system according to the first modification, corresponding to the cross-sectional views taken along line IV-IV in Fig. 2 and Fig. 5.

[0062] The speaker system 101 according to the first modification is different from the speaker system 1 according to the embodiment in that it has a flat partition plate 112. The opening 111 corresponds to the opening 11. The partition plates 131 to 133 correspond to the partition plates 31 to 33, respectively. The first space S110, the second space S120, and the third space S130 correspond to the first space S10, the second space S20, and the third space S30, respectively. The first front space S131, the second front space S132, and the communication space S133 correspond to the first front space S31, the second front space S32, and the communication space S33, respectively. The housing 110 and the partition plates 112, 131 to 133 are made of, for example, metal, resin, wood, or the like. The housing 110 and the partition plates 112, 131 to 133 may be made of the same material or different materials.

[0063] In this way, if the partition plate 112 is configured such that the front portion of the first speaker 21 is fixed to the first surface 113 of the partition plate 112 and the front portion of the second speaker 22 is fixed to the second surface 114 opposite the first surface 113 of the partition plate 112, the vibrations transmitted from the first speaker 21 and the second speaker 22 to the housing 110 can be reduced.

[0064] (Variation 2) In the speaker system 1 of the above embodiment, the first speaker 21 and the second speaker 22 are arranged facing in opposite directions to each other, but this is not limited thereto, and the direction in which the first speaker 21 faces and the direction in which the second speaker 22 faces may intersect.

[0065] Fig. 9 is a cross-sectional view of the speaker system according to the second modification, corresponding to the cross-sectional views taken along line III-III in Fig. 2 and Fig. 5. Fig. 10 is a cross-sectional view of the speaker system according to the second modification, corresponding to the cross-sectional views taken along line IV-IV in Fig. 2 and Fig. 5.

[0066] The speaker system 201 according to the second modification includes a partition plate 212 having a first plate 212a and a second plate 212b connected at a right angle to the first plate 212a. For example, the first plate 212a is arranged parallel to the YZ plane, and the second plate 212b is arranged parallel to the XZ plane. An end of the first plate 212a on the positive side of the Y axis and an end of the second plate 212b on the negative side of the X axis are fixed to each other, and the first plate 212a and the second plate 212b are integrally formed in a right-angled shape. The opening 211 corresponds to the opening 11. The partition plates 231 to 233 correspond to the partition plates 31 to 33, respectively. The first space S210, the second space S220, and the third space S230 correspond to the first space S10, the second space S20, and the third space S30, respectively. The first front space S231, the second front space S232, and the communication space S233 correspond to the first front space S31, the second front space S32, and the communication space S33, respectively.

[0067] The housing 210 and the partition plates 212, 231 to 233 are made of, for example, metal, resin, wood, etc. The housing 210 and the partition plates 212, 231 to 233 may be made of the same material, or may be made of different materials.

[0068] In this way, if the partition plate 212 is configured such that the front portion of the first speaker 21 is fixed to the first surface 213 of the partition plate 212 and the front portion of the second speaker 22 is fixed to the second surface 214 opposite the first surface 213 of the partition plate 212, it is possible to reduce vibrations transmitted from the first speaker 21 and the second speaker 22 to the housing 210.

[0069] (Variation 3) FIG. 11 is a cross-sectional view of a speaker system according to the third modification, corresponding to the cross-sectional views taken along line III-III in FIGS.

[0070] The speaker system 301 according to the third modification may include a sound-absorbing material 50 arranged in the first front space S31 and the second front space S32 of the housing 10. The sound-absorbing material 50 is not limited to being arranged in the first front space S31 and the second front space S32, and may be arranged anywhere in the third space S30.

[0071] According to this, since the speaker system 301 is provided with the sound-absorbing material 50 arranged in the third space S30, the resonant frequency based on the third space S30 can be adjusted, and the sound quality of the sound emitted from the speaker system can be effectively improved.

[0072] (Variation 4) In the above embodiment, the first space S10 and the second space S20 and the first front space S31 and the second front space S32 have the same width in the height direction at a predetermined height, but the present invention is not limited to this and may be set to different heights. In other words, the first height of the first space S10 and the second space S20 and the second height of the first front space S31 and the second front space S32 may be different.

[0073] (Variation 5) In the above embodiment, one first speaker 21 is fixed to the first surface 13 of the partition plate 12, and one second speaker 22 is fixed to the second surface 14 of the partition plate, but the present invention is not limited to this. For example, n (n is an integer of 2 or more) first speakers 21 may be fixed to the first surface 13, and n second speakers 22 may be fixed to the second surface 14. Even in this configuration, vibrations transmitted from the n first speakers 21 and vibrations transmitted from the n second speakers 22 cancel each other out at the partition plate 12, so that it is possible to reduce vibrations of the housing 10 of the speaker system 1 and to reduce vibrations transmitted to the structure on which the speaker system 1 is installed.
