Problems solved by technology

In order to achieve high-quality recording, it is necessary to adjust the positions and orientations of multiple microphones appropriately, but this setting requires high-level knowledge and experience
Also, if the equipment for setting up the microphones is included, a lot of equipment is required
As a result, it takes a lot of time to set up the system for sound pickup
In addition, it is not easy to carry

[0038] [summary of sound processing device]

[0039] The outline of the acoustic processing device in the first embodiment of the present invention will be described. In this example, the acoustic processing device is used while attached to a drum kit, and can acquire the performance sound of the drum kit and output a sound signal. It is also possible to impart a predetermined acoustic effect to the audio signal.

[0040] figure 1 It is a figure explaining the installation position of the acoustic processing apparatus in the 1st Embodiment of this invention with respect to a drum kit. The acoustic processing device 1 in the first embodiment includes a sound pickup device 10 and a control device 50 . The sound pickup device 10 is installed on the bass drum 810 . At this time, the sound pickup device 10 is configured to be detachable from the bass drum 810 .

[0084] Figure 10 It is a figure explaining the positional relationship of the microphone of the sound pickup part in 2nd Embodiment of this invention. The figure shows the Figure 8 Similarly, the positional relationship of the microphones when viewed from the front side of the sound pickup device 10 is shown. In the second embodiment, the arrangement of the microphone L 113 and the microphone R 115 is different from that of the first embodiment. In this example, the sound pickup areas of the microphone L 113 and the microphone R 115 are substantially the same as those of the first embodiment. On the other hand, the respective microphones are supported by the support plate 112 in such a manner that the directing directions of the microphone L 113 and the microphone R 115 are not crossed but set outward. The microphone arrangement described above is an example of a microphone arrangement for stereo recording, and is called an AB system arrangement.

no. 3 Embodiment approach ＞

[0086] Figure 11 It is a figure explaining the positional relationship of the microphone of the sound pickup part in 3rd Embodiment of this invention. This figure shows the positional relationship of the microphones when viewed from the upper surface side of the sound pickup device 10 . In addition, the lower side of the figure corresponds to the front side (player's side) of the sound pickup device 10 . In the third embodiment, the functions of the two microphones are different from those in the first embodiment. In the third embodiment, the support plate 112 supports the bidirectional microphone 117 and the unidirectional microphone 119 .

[0087] The bidirectional microphone 117 has bidirectionality. In this example, the two pointing directions are directed to the left and right directions viewed from the player. On the other hand, the unidirectional microphone 119 has unidirectionality, and in this example, is directed to the rear side of the sound pickup device 10 . ...

Abstract

The present invention relates to a sound pickup device and a sound processing device. One of the objects of the present invention is to facilitate the installation of a device for obtaining the performance sound of a musical instrument. A sound pickup device in one embodiment includes: a frame; a mounting portion for attaching the frame to an object; a sound pickup portion including a microphone; and a first output portion that inputs an indication to the sound pickup device. a sound signal output of the sound of the sound pickup part; a connection part that connects the sound pickup part and the frame; a sensor that detects vibration applied to the frame; and a second output part that A vibration signal output representing the vibration detected by the sensor.

Description

technical field [0001] The invention relates to sound pickup technology of musical instruments. Background technique [0002] The sound of playing with a drum kit is usually achieved using multiple microphones. The method of arranging a plurality of microphones mainly uses the method of arranging so as to surround the outside of the drum kit, or the method of arranging the microphones near the striking surface of the snare drum, tom, floor tom, and bass drum. . When the microphone is arranged near the striking surface, a method is often used in which a holder for supporting the microphone is attached to a part of the drum shell or frame other than the striking surface (head). Regarding the microphone supported by the holder, the installer adjusts the direction of the microphone so that the direction of the microphone faces the impact surface. Such a cage is disclosed in Patent Document 1, for example. [0003] Patent Document 1: Japanese Unexamined Patent Publication No....
