Detailed Description

The audio reproducing apparatus and the speaker apparatus according to the embodiments of the present invention will be described with reference to the audio apparatus 91 and the speaker apparatus 92 as examples.

First, the configuration of the audio device 91 will be described with reference to fig. 1 to 3.

Fig. 1 is an external perspective view of an audio device 91. Fig. 2 is a sectional view at positions S2-S2 in fig. 1, and fig. 3 is a sectional view at positions S3-S3 in fig. 2. For convenience of explanation, the directions of the upper, lower, left, right, front, and rear are defined as the directions indicated by arrows in fig. 1. In this example, the front-back direction is defined as a first direction, the left-right direction is defined as a second direction and an X-axis direction, and the up-down direction is defined as a third direction.

The audio device 91 is a so-called speaker-integrated stereo sound reproducing device.

As shown in fig. 1 and 2, the audio device 91 includes an outer casing 1, a main body 2, and a pair of left and

right speaker units

3L and 3R. The speaker net 4 is detachably attached to the

speaker units

3L and 3R, respectively.

The outer box 1 is made of, for example, wood, and is formed in a rectangular parallelepiped box shape. Specifically, the outer box 1 includes a front plate 11, a top plate 12, a left side plate 13, a right side plate 14, a rear plate 15, and a bottom plate 16.

The main body 2 is housed in the central portion of the outer box 1, and the front panel 2a is exposed to the outside through an opening 11a formed in the front plate 11. The main body 2 includes a CD player section, a tuner section, an amplifier section, and the like.

In fig. 2, a pair of left and right

speaker mounting holes

11b, 11b are formed on the front plate 11 of the outer box 1 on the left and right sides of the opening 11 a.

In the pair of speaker mounting holes 11b, the

speaker units

3L, 3R are mounted such that the exposed output surfaces of the diaphragms 3La, 3Ra, which are wide, face in the forward direction (first direction), respectively. The axes CL3L, CL3R of the pair of

speaker units

3L, 3R are parallel and extend in the front-rear direction. The pair of

speaker units

3L and 3R are electrically connected to the main body 2.

The audio device 91 outputs a stereo sound signal generated by a CD player unit or the like of the main body 2 and amplified by an amplifier unit as stereo sound to the front side through the pair of left and

right speaker units

3L, 3R.

As shown in fig. 2, inside the outer box 1,

partitions

51 and 52 are provided on the left and right rotation sides of the main body portion 2 disposed at the central portion in the left-right direction, and the

partitions

51 and 52 partition the internal space of the outer box 1 into the left and right sides.

That is, the audio device 91 has a speaker section 8L on the left side of the main body section 2, the speaker section 8L includes a housing 1L and a speaker unit 3L, and the housing 1L is formed by a front plate 11, a top plate 12, a left side plate 13, a rear plate 15, a bottom plate 16, and a partition wall 51.

The audio device 91 has a speaker section 8R on the right side of the main body 2, the speaker section 8R including a housing 1R and a speaker unit 3R, the housing 1R being formed by a front plate 11, a top plate 12, a right side plate 14, a rear plate 15, a bottom plate 16, and a partition wall 52.

The audio device 91 includes a pair of

speaker units

8L and 8R arranged apart from each other in the left-right direction, and a main body 2 arranged between the pair of

speaker units

8L and 8R. The audio device 91 is configured such that the

speaker units

3L and 3R of the pair of

speaker units

8L and 8R are oriented in the same direction in the front-rear direction.

Inside the speaker section 8L, a substantially closed space VL is formed as a rear chamber of the speaker unit 3L by the housing 1L.

Similarly, a substantially sealed space VR is formed as a rear cavity of the speaker unit 3R in the speaker unit 8R by the cover 1R.

Next, the internal structure of the

speaker units

8L and 8R will be described. The speaker unit 8R is configured to be bilaterally symmetric with respect to the speaker unit 8L. For this reason, the speaker unit 8L will be described as a representative example with reference to fig. 3 and 4. FIG. 3 is a cross-sectional view taken at the position S3-S3 in FIG. 2. Fig. 4 is a three-dimensional view of the sound reflection member 7 provided in the

speaker units

8L and 8R, where (a) is a front view, (b) is a plan view, and (c) is a right side view. Hereinafter, when the sound reflecting members 7 of the

speaker units

8L and 8R are distinguished from each other, the

sound reflecting members

7L and 7R are distinguished from each other.

As shown in fig. 2 to 4, the speaker unit 8L includes the housing 1L, the speaker unit 3L, the duct 17, the bottom reinforcing plate 18, and the sound reflecting member 7L.

The duct 17 is a so-called rear bass reflex type resonance tube in which the speaker portion 8L is formed. As shown in fig. 3, a rear end portion of the duct 17 is fixed to the rear plate 15 as an opening 15a, and the internal space Vd of the duct 17 communicates with the external space Vgb behind the speaker unit 8L through the opening 15 a.

The bottom reinforcing plate 18 is a rectangular thin plate-like member that is long in the front-rear direction in plan view, and is attached to the upper surface of the bottom plate 16 with an adhesive or the like.

The bottom reinforcing plate 18 is formed of, for example, wood, and is attached in a direction in which the orientation direction of the wood fibers becomes the front-rear direction. The bottom gusset 18 may be formed of a laminate having no orientation direction of the fibers.

The duct 17 has a function of adjusting reproduced sound of the speaker unit 8L, and the bottom reinforcing plate 18 has a function of indirectly adjusting reproduced sound of the speaker unit 8L by directly increasing the rigidity of the housing 1L and by making the housing 1L highly rigid.

A member disposed so as to protrude into the housing 1L, including the duct 17 and the bottom reinforcing plate 18, is referred to as a disposition member K, in addition to the speaker unit 3L. In addition, components (for example, sound absorbing material) accommodated in the cover 1L are also included in the arrangement member K.

The sound reflecting member 7L is a member that reflects sound, and is disposed inside the housing 1L. As shown in fig. 4, the sound reflection member 7L takes the shape of a triangular prism whose cross-sectional shape is, for example, a right triangle. The sound reflection member 7L is formed of, for example, wood.

The mounting surface 7Lb of the sound reflecting member 7L, which is one hypotenuse of the right triangle in the cross-sectional shape, is a flat surface, for example, a surface that is closely attached to the upper surface of the bottom plate 16.

The sound reflecting member 7 is attached so that a reflecting surface 7La, which is a plane of a hypotenuse of the right triangle in the cross-sectional shape, faces forward in the speaker unit 8L and faces the speaker unit 3L. The reflecting surface 7La reflects and refracts a part of the sound emitted rearward from the speaker unit 3L. The reflection surface 7La is inclined at an angle θ a with respect to the mounting surface 7 Lb. The cross-sectional shape of the sound reflecting member 7L may be a triangle or a quadrangle other than a right triangle. The angle θ a is, for example, 35 ° or more and less than 90 °.

As shown in fig. 2, in the speaker unit 8L, the sound reflecting member 7L is attached to the bottom plate 16 in a posture inclined at an angle θ bL toward the front side from the right side with respect to the X-axis direction as the left-right direction.

Accordingly, the reflecting surface 7La is inclined in the left direction and the upper direction as it goes forward, with the perpendicular line CL7L not parallel to the axis line CL3L of the speaker unit 3L.

The position of arrangement of the sound reflecting member 7L in the housing 1L is located forward in the front-rear direction than the foremost position P1 of the duct 17 and the bottom reinforcing plate 18 as the arrangement member K.

In the speaker section 8R on the right side, the duct 17 and the bottom reinforcing plate 18 are attached to the same position in the same shape and posture as the speaker section 8L.

However, the sound reflecting member 7R is mounted in a different posture, and in the speaker unit 8R, the sound reflecting member 7R is mounted on the bottom plate 16 in a posture inclined by an angle θ bR toward the front side from the left side with respect to the X-axis direction which is the left-right direction.

Accordingly, the reflection surface 7Ra is inclined in the right direction and the upper direction as it goes forward, with the perpendicular line CL7R not parallel to the axis line CL3R of the speaker unit 3R.

The angle θ bL and the angle θ bR are set to be in the range of more than 0 ° and 45 ° or less, respectively. In addition, the angle θ bR is the same as the angle θ bL.

Thus, in the

sound reflection members

7L and 7R of the pair of

speaker units

3L and 3R, the reflection surfaces 7La and 7Ra are surfaces that are separated from each other in the left-right direction as the respective perpendicular lines CL7L and CL7R face forward.

The sound reflection member 7 has the following functions: by being attached to the bottom plate 16, the rigidity of the housing 1L is increased, the reproduced sound of the

speaker units

8L and 8R is adjusted, and the sound field of the reproduced sound recognized by the listener is expanded for the audio device 91.

The speaker unit 8L may be provided as a speaker device 92 independently of the outer case 1, and the speaker device 92 may include a sound reflecting member 7B as the sound reflecting member 7. The reproduced sound by the speaker unit 8L of the speaker device 92 will be described with reference to fig. 7 and 8. For comparison, with reference to fig. 5 and 6, a description will be given of reproduced sound of a conventional speaker device 192 in which the sound reflecting member 7B is removed from the speaker device 92.

Fig. 5 is a vertical sectional view of the speaker device 192 without the sound reflection member 7B in the horizontal plane, and fig. 6 is a vertical sectional view of the speaker device 192 in the vertical plane. Fig. 7 is a vertical sectional view of the speaker device 92 having the sound reflecting member 7B with respect to the speaker device 192 in the horizontal plane, and fig. 8 is a vertical sectional view of the speaker device 92 in the vertical plane.

As shown in fig. 5 and 6, the speaker device 192 has a housing 1A and a speaker unit 3A. The housing 1A is made of, for example, wood, and is formed in a rectangular parallelepiped box shape. Specifically, the housing 1A includes a front plate 11A, a top plate 12A, a left side plate 13A, a right side plate 14A, a rear plate 15A, and a bottom plate 16A.

The speaker unit 3A is attached to the front plate 11A, and the duct 17A and the bottom reinforcing plate 18A are attached to the inside of the housing 1A, similarly to the speaker unit 8L of the audio device 91. Inside the speaker device 192, a space VLA almost sealed except for the duct 17A is formed as a rear chamber of the speaker unit 3A by the cover 1A.

The speaker unit 3A is connected to an audio output device corresponding to the outside of the main body 2, and converts an audio signal received from the audio output device into audio by vibration of the diaphragm 3Aa and outputs the audio signal.

The sound F1 is output forward from the speaker unit 3A, and the sound F1B is output into the space VLA as a rear chamber.

The sound F1B travels rearward substantially along the axis CL3A of the speaker unit 3A and is reflected by the inner surface of the cover 1A, and forms a sound field in the space VLA without any difference in the horizontal direction and the vertical direction.

Therefore, the cover 1A vibrates slightly in the vibration VR1 in the direction of increasing or decreasing the volume of the space VLA without any variation in the horizontal direction and the vertical direction.

Thus, the listener H positioned in front of the speaker device 192 hears the synthesized sound of the sound F1 emitted from the speaker unit 3A directly to the external space Vg and the sound emitted to the external space Vg by the vibration VR1 of the cover 1A, and forms the acoustic sound field AR 1.

Since the speaker device 192 is configured to be bilaterally symmetric, the sound field AR1 is bilaterally symmetric about the axis line CL3A of the speaker unit 3A.

On the other hand, as shown in fig. 7 and 8, the speaker device 92 has the same housing 1B and speaker unit 3B as the speaker device 192. The housing 1B is made of, for example, wood, and is formed in a rectangular parallelepiped box shape. Specifically, the housing 1B includes a front plate 11B, a top plate 12B, a left side plate 13B, a right side plate 14B, a rear plate 15B, and a bottom plate 16B.

The speaker unit 3B is attached to the front plate 11B, and the duct 17B and the bottom reinforcing plate 18B are attached as the placement member K in the interior of the housing 1B, similarly to the speaker unit 8L of the audio device 91.

Inside the speaker device 92, a space VLB almost sealed except for an opening 15Ba at the rear end communicating with the external space of the duct 17B is formed as a rear cavity of the speaker unit 3B by the housing 1B.

The speaker unit 3B is connected to an audio output device corresponding to the main body 2, and converts an audio signal received from the audio output device into audio by vibration of the diaphragm 3Ba and outputs the audio signal.

The sound F1 is output from the speaker unit 3B to the front space, and the sound F1B is output to the rear space VLB.

The sound F1B travels rearward substantially along the axis CL3B of the speaker unit 3B and is reflected by the inner surface of the cover 1B, thereby forming a sound field in the space VLB without any difference in the horizontal direction and the vertical direction.

Therefore, the cover 1B vibrates slightly in the vibration VR1 in the direction of increasing or decreasing the volume of the space VLB without variation in the horizontal direction and the vertical direction. The vibration VR1 generates a sound F3.

Further, the speaker device 92 includes an acoustic reflection member 7B, unlike the speaker device 192. As shown in fig. 4, the sound reflecting member 7B is formed in the same shape as the sound reflecting member 7L. That is, the reflecting surface 7Ba is provided as a plane corresponding to the reflecting surface 7La of the sound reflecting member 7L.

As shown in fig. 7 and 8, a part of the sound F1B emitted from the speaker unit 3B to the space VLB in the housing 1B is reflected by the reflection surface 7Ba of the sound reflection member 7B to become a reflected sound F2.

As shown in fig. 7, the sound reflecting member 7B is attached to be inclined at an angle θ B with respect to the X-axis direction so that the right side becomes the front side. The reflecting surface 7Ba of the sound reflecting member 7B is an inclined plane inclined rearward as it goes upward.

That is, the reflecting surface 7Ba is formed such that the perpendicular line CL7B is not parallel to the axis line CL3B of the speaker unit 3B, and is inclined in the left and upper directions toward the front. In other words, in the speaker device 92, the perpendicular line CL7B of the reflection surface 7Ba is not parallel to the axis line CL3B of the speaker unit 3B, and the posture inclined in the left direction and the upward direction as it goes toward the front as viewed from the front of the axis line CL3B is defined as the use posture.

Therefore, the reflected sound F2 reflected by the reflecting surface 7Ba changes the traveling direction by reflection, refracts to the left and upward, and travels mainly toward the upper left front.

The reflected sound F2 reaches the sub-vibrating portion 1BH which is a portion of the cover 1B located forward of the sound reflecting member 7B. The secondary vibrating portion 1BH is shown by a one-dot chain line in fig. 7 and 8, and mainly includes a front plate 11B, a front portion of a left side plate 13B, and a front portion of a top plate 12B.

The sub-vibrating portion 1BH generates the reflected sound F2, and vibrates with the vibration VR2 in the directions toward the upper left-oblique front and the lower right-oblique rear, which are the increase and decrease in the volume of the space VLB depending on the traveling direction of the reflected sound F2, to generate the sound F4.

That is, the sub-vibration portion 1BH of the cover 1B emits the sound F3 generated by the vibration VR1 and the sound F4 generated by the vibration VR2 to the external space Vg.

This causes the listener H who reproduces sound located in front of the speaker device 92 to hear the following sound. That is, the synthesized sound is the sound F1 directly radiated from the speaker unit 3B to the external space Vg, the sound F3 radiated to the external space Vg by the vibration VR1 of the entire cover 1B, and the sound F4 radiated to the external space Vg by the vibration VR2 of the cover 1B mainly of the sub-vibrating portion 1 BH. The listener H recognizes the acoustic sound field AR2 by the synthesized sound of the sound F1, the sound F3, and the sound F4.

Sound field AR2 synthesizes sound F4 emitted obliquely upward and forward to the left by vibration VR2 of secondary vibrating portion 1BH with respect to sound field AR1 (illustrated by a one-dot chain line in fig. 7 and 8). Thereby, the listener H can recognize the sound field AR2 as a sound field spreading obliquely upward to the left than the sound field AR 1.

In general, the sound field recognized by the listener H through the reproduced sound of the stereo sound reproducing apparatus may be wider in the left-right direction and the up-down direction. Therefore, the speaker device 92 that recognizes a sound field expanding obliquely upward and forward to the left is suitable as a speaker for the left channel.

The speaker device 92 can be used as a speaker device in which the sound field is expanded rightward and upward by being attached in an inclined posture such that the left end portion is on the front side as in the sound reflecting member 7R shown in fig. 2 by making the inclination of the sound reflecting member 7B opposite to each other.

That is, the speaker device 92 enables the listener H to aurally recognize the sound field AR2 expanded according to the direction of the reflecting surface 7Ba of the sound reflecting member 7B.

The speaker unit 8L of the audio device 91 has the same configuration as the speaker device 92. That is, as shown in fig. 2, the sound reflecting member 7L is attached to the bottom plate 16 so as to be inclined at an angle θ bL with respect to the X-axis direction so that the right end side is forward, as in the sound reflecting member 7B.

In the speaker unit 8R, the sound reflecting member 7R is attached to the bottom plate 16 so as to be inclined at an angle θ bR with respect to the X-axis direction so that the left end side is forward.

Thus, as shown in fig. 9, in the audio apparatus 91 including the

sound reflecting members

7L and 7R, the sound field AR2 recognized by the listener H positioned in front becomes a sound field AR2 that expands in the left and right directions, respectively, compared to the sound field AR1 when the

sound reflecting members

7L and 7R are not provided.

Further, since the

sound reflecting members

7L and 7R have the reflecting surfaces 7La and 7Ra inclined rearward as the sound reflecting members go upward, the sound field AR2 recognized by the listener H spreads upward further than the sound field AR 1.

In the speaker device 92, when viewed from the position of the listener H, that is, when viewed from the front side of the axis line CL3B of the speaker unit 3B in the use posture, the perpendicular line to the reflection surface 7Ba is inclined at least in the right-left direction. Thereby, the listener H can recognize the sound field AR2 that is wide in at least one of the left and right directions.

In the

speaker units

8L and 8R and the speaker device 92 of the audio device 91, the mounting positions of the

sound reflecting members

7L and 7R and the sound reflecting member 7B are located closer to the foremost position P1 of the placement member K in the directions of the axes CL3L, CL3R and CL3B of the

speaker units

3L and 3R and the speaker unit 3B.

In other words, at least a part of the reflecting surfaces 7La, 7Ra, and 7Ba is located closer to the foremost position P1 of the placement member K attached to the inside of the housings 1L and 1R and the housing 1B in the direction of the axes CL3L, CL3R, and CL 3B.

The arrangement members K in this case are the

ducts

17, 17B and the

bottom reinforcing plates

18, 18B.

Therefore, if the speaker device 92 is used for explanation, the reflected sound F2 reflected by the reflection surface 7Ba of the sound reflection member 7B is not reflected again by the placement member K, and the sound F4 is generated by directly vibrating the sub-vibrating portion 1BH of the cover 1B by the vibration VR 2. This is also the same for the

speaker units

8L and 8R.

Thereby, the listener H can more clearly recognize the expanding effect of the expanded sound field AR 2.

As described above, the audio device 91 and the speaker device 92 as the sound reproducing device can obtain a wide sound field without rotating the

speaker units

3L and 3R and the speaker unit 3B. Therefore, the audio device 91 and the speaker device 92 can be reduced in cost and easily miniaturized.

In the audio apparatus 91 and the speaker apparatus 92, even when the

speaker units

3L and 3R and the speaker unit 3B are mounted in a posture facing the front and not inclined with respect to the housings 1L and 1R and the housing 1B, a wide sound field can be obtained.

Therefore, the audio device 91 and the speaker device 92 can be miniaturized, and the degree of freedom of the design is large.

The embodiment described in detail above is not limited to the above configuration, and may be a modified example modified within a range not departing from the gist of the present invention.

In the audio device 91 as an audio reproducing device, the

speaker units

8L and 8R and the main body 2 may not be integrated with each other through the outer casing 1. The audio device 91 may be configured as a combination of the main body 2 and a pair of speaker devices 92, and the angle θ B of the sound reflecting member 7B in the pair of speaker devices 92 is bilaterally symmetric.

The reflecting surface 7Ba of the sound reflecting member 7B may have a plane not orthogonal to the axis CL3B of the speaker unit 3B. Therefore, the reflecting surface 7Ba may be perpendicular line CL7 not parallel to the axis line CL3B and inclined at least in the left-right direction.

In the speaker device 92, the placement member K is not limited to the duct 17B and the bottom reinforcing plate 18B. In space VLB, a portion or a member protruding from the inner surface of cover 1B toward space VLB and a member accommodated in space VLB, which are located on the rear side of speaker unit 3B, are arrangement members K.
