Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temple acoustic system optimal for use in ceremonies such as funerals and memorial services performed in the main hall of a temple.

[0002]

2. Description of the Related Art In ceremonies held in a wide area such as a main hall, microphones are used to collect the voices of priests' priests or Buddhist sutras to all attendees, and the sound is amplified and output by a speaker. Was there.

[0003]

[Problems to be Solved by the Invention] However, in general, the main hall of a temple is made of pure Japanese-style wooden construction made of wood, fusuma, shoji, etc., so it is visually uncomfortable to place speakers directly inside the main hall. Let In addition, the audio equipment installed in the main hall has a problem that a person near the speaker can hear it well, but a person in a distant place can not hear it well.

Therefore, if a loud voice is loudly heard by all the occupants with only one or two small speakers, it is noisy for the occupants near the speakers, but the voice of the priest's preaching or the Buddhist priest's sutras is heard. Will become unclear and spoil the solemn atmosphere and the vigorous atmosphere of the memorial service.

[0005]

The present invention has been made to solve the above-mentioned conventional problems, and the sound collected by the microphone is the same from the speaker to all the row attendants. The main purpose of the main hall is to make it possible to create an environment that gives deep sensation and a solemn atmosphere to people in the row by making it possible to hear clearly in volume and sound quality. In a temple sound system in which the speaker's audio output is amplified by a speaker and heard by the attendants, if the ceiling in the main hall is divided into a plurality of sections and the speakers are installed downward in each section, The temple is characterized in that the volume of the speaker is reduced as it gets closer to the microphone, and the synthesized volume of the real voice and the loud sound of the speaker is set to be averaged. In the use acoustic system.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS. 1 to 4. In FIG. 1, 1 is a general temple main hall, and this main hall 1 is an upper office 2 and a lower office. Outer Team 3
The main deity is enshrined at the altar 4 in the above-mentioned inner circle 2.

5 and 5A are seats for the priests, and in the case of a large memorial service, they are seated on the seat 5 in front of the altar 4 and read the sutras. Seated on the seat 5A, and a general pedestrian sits behind it. Further, microphones M1 and M2 are installed in front of the seats 5 and 5A of the priests of the inner team 2 and the outer team 3, respectively.

[0008] 6 in the ceiling of the gaijin 3, in the ceiling 6 are installed speaker SP of a plurality of the same type, in the embodiment shown in FIG. 1, a ceiling 6 3.0m ² ~5.0m ² Is divided into a plurality of sections 7 each, and one speaker SP is installed in each section 7, and 4 speakers are provided in each row.
They are arranged in rows.

[0009] In this case, the directivity of the sound output from the speaker SP is spread in all directions as bass, since narrower as made if the treble, the breadth of one zone of the speaker and the speaker is 5.0 m ² or more People in the middle are less likely to hear high frequencies. In the past, the height of the temple ceiling was about 3m.
However, when a sound in the human audible range (20 to 20,000 Hz) is output from the speaker SP having a height of 3 m, the size of the area is 3.
If it is about 0 m ² , you can hear clearly, so in consideration of economical efficiency such as the number of installations, the lower limit of the area size is 3.0.
It is set to m ^2.

Each speaker SP is installed with its opening (cone portion) facing the floor. However, when the speaker SP is hung on the ceiling 6, it is visually uncomfortable. Therefore, as shown in FIG. 2, the speaker SP is built in the closed cabinet C, and a net N for protecting and concealing the speaker SP is stretched in the sound output hole H thereof. Then, on the back surface of the ceiling 6, the front surface of the closed cabinet C is brought into close contact with the circular hole 6A, and the circular hole 6A and the sound output hole H are aligned and fixed, so that no visual discomfort is felt. To do.

If the speaker SP must be hung from the ceiling 6 by any means, as shown in FIG. 3, a closed cabinet C is placed in a gold lantern 9 or the like which is hung from the ceiling 6 by a chain 8. If the speaker SP is provided in the closed cabinet C and the sound emission hole H of the speaker SP and the circular hole 9A opened on the lower surface of the gold lantern 9 are aligned and fixed, a visually uncomfortable feeling is provided. There is no. A full-range speaker (a speaker that can cover almost all audible frequency bands) is used as the speaker SP.

The two left and right loudspeakers SP in each row are connected in parallel, and the audio system AS is installed in the room 10 adjacent to the main hall 1.
Are connected via attenuators 11A, 11B, and 11C that individually attenuate the outputs to the left and right two speakers SP of each row. The audio system AS includes an amplifier for amplifying the sound of the microphone M, a cassette deck, and a C
A D player, other audio equipment, and a control operation panel for these are provided.

Here, since all the speakers SP attached to the ceiling 6 of the outside team 3 are placed right above the seats of all the rows, its volume may be small, but as shown in FIG. The voice of the utterer, that is, the priest's voice collected by the microphones M1 and M2, becomes smaller as the position of the attendant moves away from the priest, and becomes difficult to hear.

Therefore, as shown in FIG. 1, the attenuation amount of the voice input to the speaker SP-1 of the first row located at the forefront of the outside team 3 is increased by the attenuator 11A, and then the second row at the subsequent location. The attenuation amount of the voice input to the speaker SP-2 is set to an intermediate level by the attenuator 11B, and the attenuation amount of the voice input to the speaker SP-3 of the third row is set to the attenuator 1.
1C to make it smaller, and then the fourth row speaker SP-4
The voice input to is not attenuated.

As a result, as shown in FIG. 4, the loud sound of the speaker SP is increased as the positions of the occupants move away from the occupants' seats 5, 5A, and as a result, to all the occupants of the outside team 3. The synthesized volume of the real voice of the priest and the loud sound of the speaker SP is set to be averaged regardless of the sitting position.

Therefore, voices of sutras and priests, such as sutras and sermons, are collected by the microphone M, the sound is amplified, and a large number of voices are installed on the ceiling 6 for all row seats of the outside team 3. Sound is emitted from the speaker SP. At this time, although each speaker SP is arranged directly above all the row seats with its opening facing downward, its acoustic output is small and does not reverberate on the ceiling 6 or the wall of the outside team 3, so The diffused sound is a sound source at the same distance and the same level of sound quality regardless of the seating position for each occupant, and it can be heard with a clear sound and does not feel loud.

Further, since the volume of the speaker SP-1 near the seats 5, 5A of the chief priest is low, the occupants seated near the speaker SP-1 can directly hear the voice of the chief priest.
Further, although the occupants located behind it are less likely to hear the voice of the chief priest, the volume of the speaker SP-2 is made higher than that of the speaker SP-1, and
-3 is made louder than the volume of the speaker SP-2, and further, the volume of the speaker SP-4 is made louder than the volume of the speaker SP-3. Therefore, the sense of alienation is solved by listening to the amplified sound of the real voice of the priest. To be done. Moreover, since the loud sound of each speaker SP is small as a whole, the volume of sound leaking outside the main hall 1 is extremely low.

Reference numeral 12 is a sutra table placed on the floor of the main hall 1,
A woofer (low-pitched speaker) (not shown) is built in the table 12, and the low tone reproduction enhances the majesty of the ritual, and the visual discomfort is eliminated.

[0019]

As described above, the temple acoustic system according to the present invention is a temple acoustic system in which the voice output of a microphone is amplified by a speaker in the main hall to be heard by the attendants. When the speaker is divided into individual parts and the speakers are installed downward in each partition, the volume of the speaker is reduced as it gets closer to the microphone, and the synthesized volume of the real voice and the loud sound of the speaker is averaged. Since the configuration is set so that the occupants can listen to the sound emitted from the speaker at the same distance as the sound source at the same distance and with the same level of sound quality regardless of the sitting position, There are various effects that the volume leaked to can be made very low.
