【発明の詳細な説明】 〔産業上の利用分野〕 本発明は携帯電話機に関し、特にマイクの実装構造を
改善した携帯電話機に関する。Description: TECHNICAL FIELD The present invention relates to a mobile phone, and more particularly, to a mobile phone with an improved microphone mounting structure.
従来、携帯電話機では、携帯で使用するという目的の
ため、第５図（ｂ）に概略を示すように、携帯電話機１
の本体２の形状は携帯に便利でかつ小型な直方体に近い
形状とされている。そして、送話器としてのマイク６′
はその本体２の下端側の前面位置に配設されている。Conventionally, as shown in FIG. 5 (b), for the purpose of portable use, a portable telephone 1
The shape of the main body 2 is a shape close to a small rectangular parallelepiped that is convenient to carry. And a microphone 6 'as a transmitter
Is disposed at a front position on the lower end side of the main body 2.
このような従来の携帯電話機では、第５図（ｂ）に示
すように、通話時に使用者Ｍが自身の側頭部に当てて使
用すると、口からマイク６′までの距離L2が長くなり、
マイク入力音声の対周囲雑音比が劣化し、通話音声の音
質が一般の有線電話等に比して悪くなるという問題があ
る。この問題は携帯電話機の小型化を促進するのに伴っ
て、口からマイクまでの距離はさらに遠くなり、通話の
音質は益々劣化することになる。In such a conventional mobile phone, as shown in FIG. 5 (b), when the user M touches his / her temporal region during a call and uses it, the distance L2 from the mouth to the microphone 6 'becomes longer,
There is a problem in that the ratio of the noise input to the microphone to the ambient noise is degraded, and the sound quality of the call voice is lower than that of a general wired telephone or the like. As this problem is promoted in miniaturization of mobile phones, the distance from the mouth to the microphone is further increased, and the sound quality of the call is further deteriorated.
このため、従来では口とマイクの距離を短くする目的
で、携帯電話機の形状を人間の頭の形、大きさにあった
外形となるように曲線的な形状や凹凸の大きい形状等に
することが考えられているが、通話の音質は維持できて
も携帯使用の理想である小型化の観点から見ると好まし
くない。For this reason, in the past, in order to shorten the distance between the mouth and the microphone, the shape of the mobile phone was to be a curved shape or a shape with large irregularities so that the external shape matched the shape of the human head and size. However, although the sound quality of the call can be maintained, it is not preferable from the viewpoint of miniaturization which is ideal for portable use.
さらに、この種の携帯電話機には着呼音を鳴らす等の
目的でスピーカ，サウンダといった発音体が実装される
が、携帯電話機の小型化が進むにつれて発音体の小型化
も要求され、加えて実装スペースにも余裕がなくなり、
好ましい音響効果が得られ難くなり、充分な音量，音質
の維持が非常に困難となっている。Further, a sounding body such as a speaker and a sounder is mounted on this type of mobile phone for the purpose of generating a ringing tone, etc. As the size of the mobile phone is reduced, the size of the sounding body is required to be reduced. There is no room for space,
It is difficult to obtain a desirable sound effect, and it is very difficult to maintain a sufficient volume and sound quality.
本発明の目的は、このような問題を解消し、小型化を
図る一方で音質の改善を可能にした携帯電話機を提供す
ることにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a mobile phone which solves such a problem and which can reduce the size while improving the sound quality.
本発明の携帯電話機は、使用時に本体から突出され、
未使用時に本体内に収納されるマイク保持筐体を設け、
このマイク保持筐体内にマイクを取着している。The mobile phone of the present invention is projected from the main body at the time of use,
Provide a microphone holding housing that is stored in the main body when not in use,
A microphone is mounted inside the microphone holding housing.
また、マイク保持筐体内に発音体を取着し、かつマイ
ク保持筐体の一部に音響穴を開設する。In addition, a sounding body is mounted in the microphone holding housing, and an acoustic hole is opened in a part of the microphone holding housing.
本発明によれば、使用時にはマイクはマイク保持筐体
によって携帯電話機の本体前面に突出されるため、使用
者の口との距離を短くし、音質を改善する。また、未使
用時にはマイクは本体内に収納され、その小型化を可能
とする。According to the present invention, at the time of use, the microphone is protruded from the front surface of the main body of the mobile phone by the microphone holding casing, so that the distance from the mouth of the user is shortened and the sound quality is improved. When not in use, the microphone is housed in the main body, which allows its size to be reduced.
また、マイク保持筐体に発音体および音響穴を設ける
ことで、該発音の音響特性を改善する。Further, by providing a sounding body and a sound hole in the microphone holding housing, the sound characteristics of the sound generation are improved.
次に、本発明を図面に参照して説明する。 Next, the present invention will be described with reference to the drawings.
第１図ないし第４図は本発明の一実施例を示してお

の窓に沿って出し入れすることができる。1 to 4 show an embodiment of the present invention. FIG. 1 is an external view of the embodiment, and FIG. 2 is an enlarged sectional view taken along line AA of FIG. In these figures, a mobile phone 1 is formed in a rectangular parallelepiped shape that a main body 2 can be gripped by hand, and an operation key 3 is disposed in a substantially central area on a front surface thereof. Unit 4 and display unit 5
And a microphone unit 6 is provided at the lower end of the front surface. The microphone section 6 has a microphone holding housing 6A formed separately from the main body 2 inserted into a rectangular window opened at the lower end of the front surface of the main body 2, and the upper end of the main body 2 is formed at the upper end. Are supported by a hinge 7. In the microphone holding housing 6A, the front surface 6a has a surface shape along the main body 2, the lower end surface 6b is formed as an arc surface centered on the hinge 7, and the lower end surface 6b is formed around the hinge 7 as an axis. Body 2
Can be put in and out along the windows.
そして、このマイク保持筐体6Aの前面部6aの内側に
は、マイク８とスピーカ９を取着し、マイク８に対して
は前面部6aにマイク音響穴10を開設している。また、下
端面部6bにはスピーカ９の音響を考慮した音響穴11を開
設している。A microphone 8 and a speaker 9 are mounted inside the front surface 6a of the microphone holding housing 6A, and a microphone sound hole 10 is opened in the front surface 6a for the microphone 8. In addition, an acoustic hole 11 considering the sound of the speaker 9 is provided in the lower end face 6b.
この構成の携帯電話機によれば、電話機の未使用時に
は、第１図および第２図のように、マイク保持筐体6Aは
携帯電話機１の本体２の内部に収納され、本体２の正面
から突出されることはない。これにより、携帯電話機１
の携帯性，収納性を確保する。According to the mobile phone having this configuration, when the phone is not used, the microphone holding housing 6A is housed inside the main body 2 of the mobile phone 1 and protrudes from the front of the main body 2 as shown in FIGS. It will not be done. Thereby, the mobile phone 1
Ensure the portability and storage of the device.

９の共鳴箱として機能し、下端面部6bに開設された音響
穴11の効果を相まってスピーカ９からの着呼音，音声等
の音響品質の向上を図ることができる。In addition, the microphone holding case 6A is pulled out and its internal space is enlarged, so that the microphone holding case 6A functions as a resonance box of the speaker 9, and combines the effect of the acoustic hole 11 formed in the lower end surface portion 6b. It is possible to improve the sound quality of the incoming call sound and voice from the speaker 9.
なお、スピーカ９に代えて他の発音体を設けてもよ
い。Note that another sounding body may be provided instead of the speaker 9.
以上説明したように本発明は、使用時に本体から突出

にマイクを取着しているので、使用時にはマイクはマイ
ク保持筐体によって携帯電話機の本体前面に突出される
ため、使用者の口との距離を短くし、マイク入力音声の
対雑音比を向上させることができる。また、未使用時に
はマイクは本体内に収納されるため、電話機を小型化す
ることができる。さらに、マイク保持筐体にスピーカ等
の発音体および音響穴を設けることで、誘発音体の出力
の音響品質の向上を図ることが可能となる。As described above, according to the present invention, the microphone is mounted in the microphone holding housing that is protruded from the main body when used and is stored in the main body when not in use. As a result, the distance from the user's mouth can be shortened, and the noise-to-noise ratio of the microphone input sound can be improved. Further, since the microphone is stored in the main body when not in use, the size of the telephone can be reduced. Further, by providing a sound-generating body such as a speaker and an acoustic hole in the microphone holding housing, it is possible to improve the sound quality of the output of the induced sound body.
したがって、携帯電話機の小型化によって口とマイク
の距離が遠くなることが原因とされる送話音声品質の劣
化や、小径スピーカ等の小型発音体を用いた場合および
発音体の実装スペースに余裕がとれないための音響品質
の劣化を解消する一方で携帯電話機の小型化を図ること
が可能となる。Therefore, the quality of the transmitted voice is degraded due to the fact that the distance between the mouth and the microphone is increased due to the downsizing of the mobile phone. It is possible to reduce the size of the mobile phone while eliminating the deterioration of the sound quality that cannot be achieved.
