As a result, the product of the present invention can be shared with family members, friends, and the like, and it is not necessary to bother to replace the loudspeaker 200 even when the portable model is switched.
Furthermore, if the types of mounting holes and holding parts are increased, it is possible to install most portable electronic devices from each company by simply replacing the mounting holes and holding parts, and there is no need to replace other components. It is also very economical.

For example, in the case of FIG. 15 of the second embodiment, it can be applied when the installation space is desired to be smaller, and can be loudened while looking at the screen. be able to.
Although not shown, if the mobile phone 100 is attached and the entire loudspeaker 200 is placed horizontally, it is possible to make a loud sound while keeping the screen of the mobile device 100 sideways. The other advantages are the same as those described above, and will not be described.

For example, in the case of FIG. 16 of the second embodiment, the loudspeaker can be directed to the user while viewing the screen from the front, and therefore can be applied to the case where the sound is loudest while viewing the screen. . Naturally, if the type of each resonance single tube 310 is changed, it is possible to make a louder sound with a more stable completed shape.

For example, in the case of a completed shape as shown in FIG. 13, as explained above, the resonance tube 600 can be grasped with both hands or one hand, and the sound can be heard while the sound is felt as vibration. It can be perceived as more powerful voice than just loudening only the voice.
If you simply make the sound louder, you may feel annoying and sometimes noisy, but by adding vibration to it, you can feel it as a powerful sound without making the sound louder, so the volume is higher than necessary. There is no need to do this, and the burden on the ear can be reduced and energy can be saved.
In addition, since it is possible to listen while feeling the vibration, it is possible for a hearing-impaired person to easily enjoy the music of the mobile phone 100 and the like.

As shown in FIG. 17 of the third embodiment, the portability can be improved without reducing the sound quality and the sound amplification effect. The advantage of the product of the present invention is that the material is not selected, and although not shown, it can be carried in a compressed state by making the material a very flexible material such as rubber or silicon. Portability can be further improved.
Even in the case of other shapes, basically, each member is removed and can be carried in a separated state, so that it is more portable than other types of products in which the finished shape is fixed.

As shown in FIG. 18 of the fourth embodiment, since the mobile phone 100 can be sandwiched or wrapped with the main resonance tube, it does not have a structure like the holding part 400, and even in a simple and simple combination, there are many kinds of shapes. The mobile 100 can be held.

Since the product of the present invention can arbitrarily change the path and length of sound, the diameter of the tube, the material, and the like, the user can freely adjust and change the completed shape and sound quality. For example, it is possible to change the sound quality by changing the material, such as hard and strong sound if it is a hard material such as metal, soft sound if it is wood or paper, and users can freely expand their ideas. There is a possibility to evolve and develop into various forms.

Since the product of the present invention can be applied to various mobile devices 100, it can be used as a simple wireless speaker. Usually, many people have various types of mobile phones 100, so you can use those mobile devices without using special equipment. As a (speaker), it can be attached to a plurality of products of the present invention and simultaneously arranged as a plurality of wireless speakers in a plurality of locations.
For example, it can be used in a store such as a supermarket or department store, or in an office.
Also, performances and speeches are usually used with a small number of large-capacity speakers at high volume, which is noisy near the speakers and cracks at remote locations, making it difficult to hear. If a large number of wireless speakers are arranged at regular intervals, it is not necessary to increase the volume, and the audience can hear clear sound without any sound cracking at any place.
The feature of the present invention is that portable devices that are already widely spread to individuals can be used as they are.
Wireless speakers can be downsized in the same way as computer downsizing.
