Playing the stringed instrument A in a state where it is Even if you are enthusiastic about practicing, you may have soundproofing because you can hear only the poor performance sounds Instead, he puts too much effort into the hands of Boeing to produce loud sounds.   The above-mentioned soundproofing device of the utility model is designed to solve the above-mentioned problems, and has a soundproofing effect. Despite the consequences, the conduit of the hearing equipment worn by the player is not to prevent Boeing There is a hassle that must be devised.       [0006]   Stringed instruments for soundproofing are soundproofing and are excellent as musical instruments. In addition to the stringed musical instrument A used in a row, another instrument is required for soundproofing.       [0007]   A truncated cone with a built-in sound collecting microphone 4 that is inserted into the bell of a brass instrument It is said that it is impossible to attach a mute in form to stringed instrument A in terms of shape. Problem.       [0008]   The present invention has been made in view of the above-mentioned problems, and has been particularly described in the related art. Since sound insulation for brass instruments is excellent, apply it to a receiver or amplifier. The above-mentioned sound collecting microphone 4 used in combination with the headphone and the earphone It has a sound collection function that can be attached to the stringed instrument A instead of the stored brass instrument for brass instruments. The task is to provide soundproofing equipment.       [0009]     [Means for solving the problem]   In order to achieve the above object, the soundproofing device with a sound collector for a stringed instrument in the present invention is: Sound insulation material that can be used to cover the f-shaped sound hole of a stringed instrument It is manufactured by combining with a sound collecting microphone including a wireless type. It is. The soundproofing device with a sound collecting device according to the present invention is a sound collecting device in which a sound collecting microphone is provided as a sound insulating material. In the form of being incorporated into the hole, or as shown by the two-dot chain line in the figure, The sound-insulating material covers the sound hole to prevent sound. At the same time, the microphone collects the sound of the stringed instrument at the same time.       [0010]     [Embodiment of the invention]   Embodiments of the invention will be described based on examples with reference to the drawings.   FIG. 1 shows a stringed instrument (A) equipped with a soundproofing device (B) with a sound collector according to the present invention, Cross section when the trunk is cut at a right angle to (9) and detached from the piece (5) It is a schematic diagram.   The soundproofing device B with a sound collector of the present invention is used so as to cover the f-shaped sound hole 1 of the stringed instrument A. A sound collecting microphone including a soundproof material 3 that can be mainly attached to the front plate 2 and a wireless type. 4 in combination.       [0011]   An example in which the sound collecting microphone 4 is incorporated in the sound collecting hole 6 will be described.   The sound insulating material 3 is made of soft material such as rubber or felt, and is provided on the front plate 2 of the stringed instrument A. It is good to use a plate-shaped one that is large enough to cover the f-shaped sound hole 1 No. If it does not prevent Boeing, it need not be flat.   A sound collection hole 6 is provided substantially at the center of the soundproofing material 3, and a sound collection microphone 4 is assembled in the sound collection hole 6. The soundproofing material 3 should be slightly retracted from the contact surface 3a with the front plate 2. When the sound collecting microphone 4 is installed, there is a concern that the sound collecting microphone 4 may damage the top plate 2 when it is mounted. Disappears.   To make the plate-shaped soft sound-insulating material 3 adhere to the surface plate 2 having a curved surface, Using the hard jacket 7 on top, the soundproofing material 3 is placed on the top of the jacket 7 with the elastic band 8 It is good to press it on 2 and attach it. Then, the contact surface 3a of the soundproofing material 3 with the front plate 2 is displayed. It is deformed to correspond to the curved surface of the plate 2, and there is no gap between the front plate 2 and the soundproof material 3. Therefore, it is possible to prevent the reverberation sound in the stringed instrument A cavity from spreading directly from the sound hole 1 to the surroundings.   Sound collecting microphone 4 requiring long connection cord 10 and wireless sound collecting microphone 4 is shown as a common one, but in the case of a wireless connection, Is used as an antenna, and the case 4a of the microphone 4 is A small battery 11 shown by a dotted line in the figure is required.   The sound collecting microphone 4 has a substantially cylindrical shape. In order to be incorporated in the sound collecting hole 6, an insertion port 12 is provided at a substantially central portion of the jacket 7, and a case When the sound collecting microphone 4 is inserted into the insertion port 12 with the rubber sealing ring 13 attached to the portion 4a, good. In addition, one of the two sound holes 1 is covered with a soundproofing device B with a sound collector, and the other one. Is obtained by merely stacking the jacket 7 without the insertion port 12 on the soundproofing material 3 without the sound collection hole 6. The soundproofing device C may be attached so as to cover the soundproofing device C, or the soundproofing device B with a sound collector may be mounted on both.       [0012]   The soundproofing device B with the sound collector manufactured as described above is attached to the stringed musical instrument A, and a wire is attached. Sound collecting microphone 4, the sound collecting microphone 4 is collected at the receiver of the audio equipment. In the case of the sound collecting microphone 4 which requires the connection cord 10 to receive the sound that has been sounded, the connection cord Connect the end of 10 to the amplifier, and the player can use headphones or earphones as a receiver or If you play the stringed instrument A with the amplifier attached to your ear, You can hear only a small sound with hole 1 covered with soundproofing material, but the player hears a loud sound. come. Although the case part 4a is located beside the piece 5, it does not prevent boeing, If necessary, the installation position of the sound collecting microphone 4 may be moved to the near side. Connection code 10 In order not to prevent Boeing from being prevented. Because the connecting cord 10 is thinner and easier to bend than the conduit of the hearing aid in the new model Easy to devise. In the case of the wireless sound collecting microphone 4, the connection cord 10 is short. There is no need to worry about preventing Boeing. Especially like cello and double bass When the stringed musical instrument A is set up vertically, the connection cord 10 serving as an antenna is cut short. Is naturally drip-down and does not prevent Boeing, making it easy and convenient to use. You. Further, the above-described sound collecting microphone 4 does not necessarily have to be substantially cylindrical.   When the soundproofing device B with a sound collector according to the present invention is attached to the stringed musical instrument A, the existing mute 14 The sound that can be heard in the surroundings when the piece is attached to the piece 5 is when the soundproofing material 3 just covers the sound hole 1. Even smaller. Naturally, the sound that can be heard by the player will also be lower, but the receiver and The higher the volume of the loop, the louder the sound heard by the player.       [0013]   Next, as shown by the two-dot chain line in the figure, the sound collecting microphone 4 is inserted from the sound hole 1 into the cavity of the stringed instrument A. The inserted form will be described with an example.   To insert the sound-collecting microphone 4 into the stringed instrument A cavity, push down the cylindrical case 4a. You just need to do it. To insert the sound collecting microphone 4 from the sound hole 1 into the stringed instrument A cavity, Considering the limited width of the sound hole 1, consider the outside of the entire sound collecting microphone 4 including the case 4a. It is necessary to determine the diameter of the circumference.     Inserting the sound collecting microphone 4 into the cavity of the stringed instrument A is performed while the performer echoes. Then, the sound collecting microphone 4 is installed in the sound insulating material 3 and the sound collecting hole 6, and the sound collecting The sound collection effect is better than when the sound 4 is installed at the exit of the sound hole 1, that is, outside the stringed instrument A. Is good. Combination of the above soundproofing material 3 and the sound collecting microphone 4 inserted into the stringed instrument A cavity The soundproofing device B with a sound collector is attached to the front plate 2 so as to cover the left and right sound holes 1. When you play the stringed instrument A, you will only hear a small sound around you, but the sound collecting microphone 4 The sound collected in the stringed instrument A cavity is transmitted to the headphone via the receiver or amplifier. The player can hear the sound as loud from the earphones. Existing mute 14 The form of being attached to the piece 5 is the same as described above.   The above is an example of the embodiment, and the sound collecting microphone 4 does not necessarily have to be substantially cylindrical.       [0014]   One of them is equipped with a sound collector to cover the left and right sound holes 1 of the stringed instrument A. A cover fitted with soundproofing device B and the other covered with simple soundproofing device C; When comparing the sound absorber with sound collector B in the form of both, the receiver Or, if the volume of the amplifier is constant, the latter form is better However, the volume that can be heard from the earphone to the player's ear increases.   However, if you increase the volume of the receiver and amplifier in the former form, You can listen to the same volume as in the case where two sound tools B are installed, and only one sound collecting microphone 4 is required. No.       [0015]     [Effect of the invention]   Since the present invention is configured as described above, it has the following effects.   String music that can be attached in close contact with the front plate by covering the f-shaped sound hole of the stringed instrument A soundproofing device with a dexterous sound collector is provided.       [0016]   Attach the above sound protectors with sound collectors to stringed instruments, and Head connected to the receiver or amplifier of the audio equipment and worn by the player Connect a horn or earphone to the receiver or amplifier to play a string instrument And you can hear only a small sound around you, but you can hear the loud sound . The soundproofing device with a sound collector can be easily attached to and detached from a stringed instrument.       [0017]   If the pickup microphone requires a long connection cord, Although it is necessary to devise it so that it does not prevent rolling, Easy to devise, a wireless sound collection device that cuts the connection cord short and uses it as an antenna In the case of a war, there is no need to worry about preventing Boeing.
