Abstract

To provide a microphone sponge for attenuating an input to a microphone concerning peripheral noise other than voice of an utterer.SOLUTION: In a microphone sponge 1, a sponge material other than that in a mouth peripheral part 2 of an utterer when a microphone is used is allowed to be thicker than a sponge material in the mouth peripheral part 2 of the utterer. Alternatively, the sponge material other than that in the mouth peripheral part 2 of the utterer when the microphone is used is allowed to be thicker than the sponge material in the mouth peripheral part 2 of the utterer, and also the sponge material is extended in a direction to cover a mouth of the utterer concerning the microphone sponge 1.SELECTED DRAWING: Figure 1

Description

本願発明は、周囲騒音を軽減して発声者の音声をマイクで拾いやすくするためのマイクスポンジに関する。 TECHNICAL FIELD The present invention relates to a microphone sponge for reducing ambient noise and making it easier to pick up a speaker's voice with a microphone.

ビデオ会議等において、遠隔地の発声者が周囲騒音の大きい環境（交通量の多い道路、工事現場、工場など）にいる場合、発声者の音声が周囲騒音によって聞き取りにくいことがある。このような場合には、従来技術では、指向性マイクの使用や、音声信号のノイズキャンセリング処理により対応することがあるが、十分に聞き取りやすくはならないこともある。 In a video conference, etc., when a remote speaker is in an environment with a lot of ambient noise (roads with heavy traffic, construction sites, factories, etc.), the voice of the speaker may be difficult to hear due to the ambient noise. In such a case, the conventional technology may use a directional microphone or apply noise canceling processing to the audio signal, but it may not be possible to make it sufficiently easy to hear.

ビデオ会議等において、遠隔地の発声者が周囲騒音の大きい環境（交通量の多い道路、工事現場、工場など）にいる場合、発声者の音声が周囲騒音によって聞き取りにくいことがある。このような場合には、従来技術では、指向性マイクの使用や、音声信号のノイズキャンセリング処理により対応することがあるが、十分に聞き取りやすくはならないこともある。 In a video conference, etc., when a remote speaker is in an environment with a lot of ambient noise (roads with heavy traffic, construction sites, factories, etc.), the voice of the speaker may be difficult to hear due to the ambient noise. In such a case, the conventional technology may use a directional microphone or apply noise canceling processing to the audio signal, but it may not be possible to make it sufficiently easy to hear.

本願発明は、発声者の音声以外の周囲騒音について、マイクへの入力を減衰させるためのマイクスポンジを提供するものである。 The present invention provides a microphone sponge for attenuating the input to the microphone of ambient noise other than the voice of the speaker.

マイクスポンジ１において、マイク使用時における発声者の口元周辺部分２以外のスポンジ材を、発声者の口元周辺部分２のスポンジ材よりも厚くする。または、マイクスポンジ１において、マイク使用時における発声者の口元周辺部分２以外のスポンジ材を、発声者の口元周辺部分２のスポンジ材よりも厚くし、かつ、マイク使用時における発声者の口元を覆う方向にスポンジ材を延長する。 In the microphone sponge 1, the sponge material other than the mouth peripheral part 2 of the speaker when using the microphone is made thicker than the sponge material of the mouth peripheral part 2 of the speaker. Alternatively, in the microphone sponge 1, the sponge material other than the speaker's mouth peripheral portion 2 when using the microphone is made thicker than the sponge material for the speaker's mouth peripheral portion 2, and the speaker's mouth when using the microphone is made thicker. Extend the sponge material in the covering direction.

厚みを持ったスポンジ材により周囲騒音のマイクへの入力は減衰するが、発声者の音声は、発声者の口元周辺部分２のスポンジ材が前記厚みよりも薄い分、マイクへの入力減衰が少ない。このため、マイクへ入力される音量のうち、発声者の音声がしめる割合が、マイクスポンジ１非装着時と比較して高くなり、発声者の音声を拾いやすくできる。 Ambient noise input to the microphone is attenuated by the thick sponge material, but input attenuation of the speaker's voice to the microphone is small because the sponge material of the mouth peripheral portion 2 of the speaker is thinner than the thickness. . Therefore, the speaker's voice accounts for a higher proportion of the volume input to the microphone than when the microphone sponge 1 is not attached, making it easier to pick up the speaker's voice.

特許文献１には、漏音防止マイクロフォンが開示されており、これは発声者の音声以外の周囲騒音を軽減する効果も期待できるものと考えられるが、発声者の息によるポップノイズを軽減するための対策が別途必要である。対して、本願発明では、発声者の音声に対しては一般的なマイクスポンジとしての効果があるため、前記ポップノイズ軽減に対する別途対策は必要ない。 Patent document 1 discloses a sound leakage prevention microphone, which is expected to have the effect of reducing ambient noise other than the speaker's voice. measures are required separately. On the other hand, in the present invention, since there is an effect of a general microphone sponge for the voice of the speaker, there is no need for additional measures to reduce the pop noise.

本願発明は、前記従来技術の、指向性マイクの使用や、音声信号のノイズキャンセリング処理、と併用することが可能であるため、これらと併用することにより、これら従来技術の効果との相乗効果が期待できる。 Since the present invention can be used in combination with the use of a directional microphone and the noise canceling processing of audio signals in the above-described conventional technology, synergistic effects with the effects of these conventional technologies can be obtained by using them together. can be expected.

Alternatively, in the microphone sponge 1, the sponge material other than the speaker's mouth peripheral portion 2 when using the microphone is made thicker than the sponge material for the speaker's mouth peripheral portion 2, and the speaker's mouth when using the microphone is made thicker.
