(57) [Abstract] [Purpose] A closed microphone case allows ambient noise, mechanical operating noise, and wind noise to be mixed into the microphone sound, and can be used as an underwater microphone as well. The built-in electret condenser microphone and dynamics microphone By adding a piezoelectric ceramics element or cartridge as a microphone unit together with the unit, the voice that tends to be low tone is supplemented to the high frequency range, the sound pressure is further lowered, and the characteristics of the skin contact closed case vibration conduction type voice microphone are improved. It was made up of a two-way microphone system product. . [Structure] With a structure that detects vibrations of vocal cords in a sealed microphone case and converts them into audio signals, using only conventional electret condenser microphones and dynamics microphone units to compensate for characteristics that tend to cause high sound and insufficient sound pressure. By adding a piezoelectric ceramic element and a cartridge and using two different types of microphone units, we have created a product with a 2-way microphone system configuration that obtains a high sound range and high sound pressure.
Description
【0001】[0001]
騒音や強風の環境下や水中マイク、建築現場、空中ヘリコプター内やバイク走行 中、工作機械や印刷機の作動中の騒音な工場内でのマイク使用が可能になり、皮 膚振動感知で小声でも普通と同音圧レベルになり、大声でも使用できる音声振動 マイクロホン装置です。声帯ガンで50%、30−20%のみ声帯が残り音圧が 低く発声しにくい人には、美声にはなりませんが、無理な大声による発声をしな くてよい。 Microphones can be used in noisy and windy environments, underwater microphones, construction sites, aerial helicopters, motorcycles, and machine tools and printing machines that are operating in noisy factories. It is a voice vibration microphone device that has the same sound pressure level as normal and can be used even in a loud voice. Only 50% and 30-20% of vocal cords have vocal cords remaining and the sound pressure is low and it is difficult to vocalize, so it is not a beautiful voice, but it is not necessary to vocalize in an unreasonable loud voice.

エレクトレットコンデンサーマイクやダイナミックスマイクのみで密閉マイクケ ースで使用すれば、高音域が伸びず更に音圧が低くなり聞き難いマイク音になり ますが、圧電セラミックスエレメントやカートリッジを追加して2−ウェイマイ クロホンシステムで2種類のマイクユニットで高音域と高音圧を補うシステムに した。 If you use only an electret condenser microphone or a dynamics microphone in a closed microphone case, the high range will not be extended and the sound pressure will be further lowered, making the microphone sound difficult to hear, but by adding a piezoelectric ceramic element and a cartridge, 2-way mi A system that complements the high range and high sound pressure with two types of microphone units in the Krohon system.

マイクを騒音下や塵の多い所、水中で使用する為に密閉マイクケースを使う振動 伝導型マイクはマイク音が低くなり、こもりがちで高音が伸びず、更に音圧が低 くなりがちなので、高音域を補い上げて高音圧が得られる為にエレクトレットコ ンデンサーマイクやダイナミックスマイクユニットに圧電セラミックスエレメン トやカートリッジユニット追加使用の2−ウェイマイクロホンシステムで解決し た。 Use a closed microphone case to use the microphone under noisy conditions, dusty places, or underwater. Vibration-type microphones tend to have low microphone sound, tend to be muffled, do not extend high frequencies, and have low sound pressure. In order to supplement the high range and obtain high sound pressure, we solved it with a 2-way microphone system that uses a piezoelectric ceramic element or a cartridge unit additionally in the electret condenser microphone or dynamics microphone unit.

首に固定するホルダーを弾性ステンレスで作ったり、マイク本体のみをヘヤーバ ンドの内側に装着したり、メガネのツルに付けて「こめかみ」より感知しらり、 ヘッドホンに埋め込み「顎」より喉声帯振動感知したり、「首の横」の箇所の皮 膚より感知する密閉間接振動伝導型2−ウェイ内臓のマイクロホンシステムにし た。 The holder to be fixed to the neck is made of elastic stainless steel, only the microphone body is attached to the inside of the hairband, it is attached to the temple of the glasses and it is detected from the "temple", and it is embedded in the headphone and the throat vocal cord vibration is detected from the "jaw" In addition, a closed indirect vibration conduction type two-way built-in microphone system that senses from the skin “side of the neck” is adopted.

品質保護と耐用性も高める為に密閉マイクケースで得られ、騒音がマイク音に入 りにくく、2−ウェイマイクロホンシステムで高音域と高音圧が得られることで マイク音が騒音下でも聞き取り易くなり、車中や静かな場所で小声で十分な音圧 で相手に伝わり、大声で周りに迷惑をかけず、ハンズフリーで作業中でも両手が 使え、警察官の尾行中でも服の中に隠し目だたずに雑音騒音の少ないマイク音連 絡使用ができ、PHS携帯電話、無線機、警察無線機等に使用できるマイクロホ ンシステムです。 Obtained in a sealed microphone case to improve quality protection and durability, noise is less likely to enter the microphone sound, and the 2-way microphone system provides high range and high sound pressure, making the microphone sound easy to hear even in the noise. In a car or in a quiet place, the voice is transmitted to the other party with a sufficient sound pressure, does not disturb the surroundings loudly, both hands can be used even when working hands-free, and it is a hidden concealment in clothes even when a police officer is following. It is a microphone system that can be used for PHS mobile phones, radios, police radios, etc. without any noise and noise.

クロホン1. A closed microphone case prevents ambient noise, mechanical operating noise and wind noise from entering the microphone sound, and has a dustproof function so that it can be used as an underwater microphone. By adding a piezoelectric ceramics element and a cartridge and using two different types of microphone units, the voice that tends to be low-pitched can be supplemented to the high-pitched tone, and the low sound pressure becomes higher, resulting in a 2-way speaker system. A two-way microphone that uses two types of microphone units, a skin contact type closed case and a vibration conduction type, which have various characteristics in the microphone.
