Problems solved by technology

[0006] However, most horn devices except for the woofer are arranged in a straight line, but they are not arranged to eliminate the arrival time difference of the radiated sound of each speaker (for example, refer to Patent Document 1). This is because when the sound source of each speaker is set in order to eliminate the arrival time difference of the radiated sound of each speaker, since the front end of the horn of the long mid-range speaker protrudes, a short-horn tweeter or a direct-radiating bass will appear. The radiated sound of the horn is reflected and shifted by the horn of the mid-range horn
Also, if only the horn of the mid-range speaker protrudes forward, the appearance of the speaker device will lack a sense of integrity.

Embodiment 1

[0071] figure 1 It is a perspective view of the speaker device 1 of the first embodiment. The speaker device 1 has two kinds of speakers, a mid-range speaker 4 and a high-frequency speaker 5, and forms a 3-way speaker system with other speaker devices (not shown) having a woofer. That is, in the speaker device 1 of the present embodiment, the mid-range speaker 4 becomes the reference speaker of the present invention.

[0072] Such as Figure 1~4 As shown, the speaker device 1 of the present embodiment includes a long and rectangular baffle plate 2 . This resistance board 2 is made of the synthetic board of width 40cm * height 82cm * thickness 18mm. A rectangular opening 9 a is formed at the center of the baffle plate 2 , and the midrange speaker 4 is attached to the opening 9 a from the back side. The mid-range speaker 4 is made of a conical full-range speaker with a diameter of 18cm. The back side of the midrange speaker is surrounded by an airtight casing 11 with a volu...

Embodiment 2

[0093] FIG. 8 is a perspective view of the speaker device 1b of the second embodiment. The speaker device 1b is a part of the configuration of the speaker device 1 of the first embodiment described above, and the description of the common parts among the related configurations is omitted.

[0094] The speaker device 1b of this embodiment is provided with three kinds of speakers including a woofer 3, a mid-range speaker 4 and a high frequency speaker 3, and only this speaker device 1b constitutes a 3-way speaker system. That is, in the speaker device 1b of this embodiment, the mid-range speaker 4 is the reference speaker of the present invention. The mid-range horn 4 and the high-frequency horn 5 provided in the horn device 1b are the same as those in Embodiment 1, and the woofer 3 is a conical horn with a diameter of 30 cm.

[0095] The horn device 1b has a slightly longer baffle plate 2 than in Example 1, a mid-range speaker 4 is disposed approximately in the center of the b...

Embodiment 3

[0108] Figure 14 It is a perspective view of a horn device 1c of Example 3 including a horn-type high-frequency horn. This horn unit 1c differs from the horn unit 1b of the second embodiment only in the configuration near the high-frequency horn attachment part, and the description of the common parts of the configuration will be omitted.

[0109] In the speaker device 1c of the present embodiment, the horn 17 is arranged instead of the enlarged wall pair 12 for tweeters at the mounting position of the high-frequency speaker 5 in front of the baffle plate 2a. The horn 17 is designed to increase the radiated sound of the high-frequency horn 5, and the high-frequency horn 5 is arranged behind the slit 9c of the horn 17. This high-frequency horn 5 is the same as the horn of embodiment 1.

[0110] The side plates 17b, 17c on the left and right sides of the horn 17 are smoothly joined to the inner wall surface of the enlarged wall pair 10a, and the radiated sound of the high-fre...

Abstract

Provided is a speaker device formed by a plurality of speakers having identical time required for reach of the emitted sounds, increasing the sound pressure of speakers other than a woofer like the horn-type speaker, integrating the speaker units which are dispersed in the conventional horn use so as to integrate the functions of the respective speakers, and exhibiting a single external form. Two or more types of speakers (3, 4, 5) including a reference speaker (4) for reproducing a high sound side band adjacent to the reproduction band of a woofer (3) are inline-arranged on a baffle plate (2). At the front side of the baffle plate (2) is arranged an increased wall pair (10a) passing through the right and left side of the emission surface of the reference speaker (4), vertically crossing the front surface of the baffle plate (2), and expanding rightward and leftward toward forward. The emitted sound of the reference speaker (4) is increased by the inner space of the increased wall pair (10a) without increasing the emitted sound of the woofer (3).

Description

field of invention [0001] The invention relates to a loudspeaker device, which is composed of more than two kinds of loudspeakers with different playing frequency bands arranged in-line on a baffle. Background technique [0002] The speaker device is composed of two or more types of speakers with different playback frequency bands arranged in a straight line on the blocking plate. The most common one is to have three types of speakers for treble, midrange, and bass, forming a 3-way speaker system. In addition, there are devices that constitute other four or more speaker systems, and there are devices that constitute a speaker system by using it in combination with a speaker device that broadcasts speakers of other frequency bands. [0003] Generally, the speakers that make up the speaker system have different names according to their playing frequency bands. If it is a 3-way system, starting from the speaker on the bass side, it is called a woofer, a mid-range speaker, and a...
