[Previous Technology] The popularity of mobile phones has been amazing recently, and has reached the per capita level. Along with its popularity, miniaturization and advancement of portable telephones have also progressed, and the loudspeaker device used for it has also been required to increase its miniaturization. Generally speaking, the loudspeakers of portable telephones use sound pressure type loudspeakers. The loudspeaker is equipped on the upper part of the case of the mobile phone, and the sound hole provided from the upper part of the front side of the body case is sounded, and the sound hole is close to the ear hole for listening. This sound pressure type loudspeaker has its own limitation because the diaphragm has a tapered structure, and its size and thickness are reduced. Recently, instead of the above-mentioned sound pressure type loudspeaker, a mobile phone 3 using a bone conduction loudspeaker using a bone conduction microphone to transmit sound by research has been studied. FIG. 4 shows a structure of a mobile phone using the bone conduction loudspeaker. The bone conduction loudspeaker 21 contains a vibration system composed of a yoke, a magnet 24, and a voice coil 25 in a case 22, and a vibration plate 26 fixed to the 23, and borrowed from the case 22 The inner side of the fixed vibration plate is thus configured. The bone conduction loudspeaker 21 is mounted on the upper surface side of the housing 31, and is mounted in a protruding state via a cushioning material 3 2 for countermeasures against vibration (h a w 1 i n g). [Summary of the Invention] (Problems to be Solved by the Invention) 312 / Invention Specification (Supplement) / 93-03 / 92134158 Some properties, thin sound pressure is set on the beard, and the bone vibration is required. Figure [example. When the 23 yoke 26 is used, it is installed 5 200421823 When the mobile phone using the above-mentioned bone conduction microphone is used, the conduction microphone is installed in a protruding state and becomes a hindrance, especially in a foldable configuration. Therefore, the object of the present invention is to provide a bone conduction microphone which does not protrude from the main body of the machine. The bone conduction microphone does not become a hindrance when it is configured to be folded, and it can be used even under high noise. Mobile phone with bone conduction speaker. (Means for solving the problem) In order to solve the above-mentioned problem, the telephone of the bone conduction microphone used in the present invention is such that the vibration plate of the bone conduction microphone is directly fixed to the upper part of the inner side of the front side of the casing, and then the bone The conductive loudspeaker is assembled on the housing of the main body, and is thus characteristic. The aforementioned body casing may also be of a stacked type. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is an oblique view of an important part of a portable telephone equipped with a bone-conducting loudspeaker of the Ming, and a cut-away view of an important part thereof. In the figure, 1 is the main body casing, and like the previous mobile phone, it is equipped with a cable 2, a daylight surface 3, and an operation key (not shown). On the upper side of the inside of the main body casing 1, a bone conduction microphone 4 is provided. In this case, it is not necessary to provide a sound emitting hole in the speaker setting section as before. The bone conduction loudspeaker 4 is a yoke 5 with a circular shape; and a magnet 6 disposed along the inner surface of the yoke's peripheral wall; and a voice coil 7 wound in the yoke 5 (ρ ο 1 e). And, it is fixed on the open side end face 312 of the yoke 5 / Invention Specification (Supplement) / 93-03 / 92134158 for bone discomfort and self-interference. , 5 of the heart pole vibration 6 200421823 moving plate 8; so constituted. The bone conduction loudspeaker 4 is provided on the upper portion of the main body housing 1 so that the vibration plate 8 is directly fixed to the inner side surface of the main body housing 1. In this way, since the bone conduction microphone 4 is directly mounted on the inner surface of the main body casing 1, the main body casing 1 itself can operate as a vibration plate of the microphone. Therefore, a person with normal hearing can use it as an audio loudspeaker, and since vibration can be transmitted from the entire body casing 1, the user can listen to bone conduction sound and air vibration sound at the same time. Therefore, people with normal hearing can use more natural sound quality to listen to, and people with low hearing can also use it. In addition, since the entire body case 1 is a vibration plate, it is not necessary to make the sound emitting hole (small hole) and the ear hole consistent with each other, unlike a general sound pressure type loudspeaker. When the bone conduction microphone 4 is directly mounted on the inner surface of the main body casing 1 as described above, there is a problem of howling. However, recent mobile phones have been digitized, and since they are equipped with a high-performance noise canceller, the noise problem can be eliminated. In particular, the folding type mobile phone has a structure in which a speaker assembly and a microphone assembly are separated, so that there is no problem of howling. The mobile phone of the present invention uses a bone conduction microphone in particular. Therefore, under high noise, if the ear is plugged with an earplug or the like, it will not be affected by the noise and can talk. (Effects of the Invention) Since the present invention is constructed as described above, the bone conduction microphone assembled on the inner side of the casing can have a comfortable design without protruding portions. There is no restriction on the connection part. 7 312 / Invention Specification (Supplement) / 93-03 / 92134158 200421823 There is no use of the 1 aspect and there is no vibration problem. For normal hearing or hearing impaired people. There will be no uncomfortable use.
