Description

Stand type speaker for portable devices

The present invention relates to a stand-type speaker for a portable device, and more particularly to a stand-type speaker for a portable device having a function of amplifying sound emitted from the portable device by utilizing the effect of a hollow structure and a laminated structure.

In recent years, mobile devices have become popular, and many types of smartphones have been released by mobile carrier companies. These smartphones also have a digital music player function and a function for viewing moving images, and some have a speaker on the side so that music and video can be viewed without using earphones or headphones.

Conventionally, there is a stand-type speaker for a portable device that has a function of amplifying sound emitted from the speaker by placing the portable device. Many of these stand-type speakers have a shape close to a cube, and are not supposed to be carried, so they are inconvenient to carry.

Also, since the built-in amplifier is used to amplify the sound coming from the speaker of the mobile device, it is essential to supply power.

As an invention to compensate for the above-mentioned drawbacks of these stand-type speakers, there is one disclosed in Patent Document 1. This portable terminal stand has a horn shape formed by folding smooth paper into a cylindrical shape, placing the portable terminal on the top surface, and transmitting the sound emitted from the speaker at the bottom of the portable terminal to the internal structure of the stand Is amplified from the horn part of the stand.

However, there are drawbacks listed below. Since the sound emitted from the speaker of the portable terminal can be emitted only from the horn part of the portable terminal stand, the sound amplification effect is limited.

Also, since there is a distance of several centimeters from the position where the speaker of the mobile terminal is inscribed in the horn part of the mobile terminal stand to the sound outlet of the horn part, the sound from the speaker of the mobile terminal passes through that distance. The direction is limited to a certain direction. Moreover, since the horn part faces the front, the direction of the sound emitted from the horn part is limited.

Also, it is not suitable for carrying because of its contoured outer shape.

Also, it cannot be used unless it is assembled. In order to make it easy to carry, it is essential to disassemble the main body, which is a folding structure, into a flat surface, and reassemble it when it is used.

Also, it is unstable because only the lower end of the mobile terminal is inserted into the stand.

Therefore, the stand installation direction is limited, and it can be installed only on a plane that is horizontal and flat with respect to the ground, such as on a desk.

Therefore, the standing direction of the mobile terminal to be placed is also limited, and the screen of the mobile terminal can be viewed only vertically.

Also, since the structure covers the operation buttons on the front of the mobile terminal, the operation is hindered.

Noto 3187549

In view of the above-described conventional drawbacks, the present invention is characterized in that sound emitted from a speaker of a portable device (for example, a smartphone) is amplified not only by being emitted from a sound emission opening but also by resonating the entire main body. .

Also, since the sound emitted from the speaker of the portable device is amplified by resonating not only the horn but also the entire main body, the sound direction is not limited.

Also, it has a flat shape suitable for carrying.

Also, since no assembly process is required, it can be used immediately when you want to use it.

Also, it can be stably placed to store the entire mobile device.

Therefore, since the standing direction of the main body is not limited, the place where it can be used is not limited, and even if it is installed so that the screen of the mounted mobile device is parallel to the ground, it can be raised and lowered in the vertical direction. It can be used even when installed.

Therefore, the main body on which the mobile device is placed can be turned 90 degrees in the left-right direction with the screen of the mobile device in front, so that the mobile device screen is viewed horizontally when viewing a video or the like. It is characterized by being able to.

Also, it is characterized in that the operation buttons on the front of the mobile device can be exposed and placed, so that the operation is not hindered.

Moreover, the direction of the sound is not limited because the sound emitted from the speaker of the portable device is amplified by resonating not only the horn but also the entire main body.

Furthermore, since the effect of the structure is used, it is not necessary to supply power.

Moreover, since it is a flat shape formed only of the upper and lower plates and a plurality of cores and partition plates, it is therefore easy to carry and highly convenient to carry.

Moreover, the assembly process is not required because it is an integrated type.

In addition, the portable device can be stably placed by providing a storage unit on which the entire portable device can be placed.

Therefore, since the standing direction is not limited, the place where it can be used is not limited. Other than on a plane that is horizontal and flat with respect to the ground, such as a desk, for example, on a surface that is not horizontal or smooth with respect to the ground outdoors, or the screen of a mobile device that is placed is perpendicular to the ground It can be used by rolling up and down.

Therefore, it can be used regardless of whether the screen of the mobile device placed is in the portrait or landscape orientation, which is very convenient for viewing videos.

In addition, by providing a storage unit on which the entire portable device can be placed, the structure can be placed with the front surface completely exposed, so that the operation buttons on the front surface are not covered and the operation is not hindered.

Also, it is possible to easily change the size of the main body and the storage unit in accordance with the size change of the portable device. Therefore, it is highly versatile and suitable for mass production.

Furthermore, paper (particularly preferably cardboard) can be used as a material. Paper can be recycled, giving consideration to the global environment.

Also, it is lighter than conventional wood and metal materials.

Also, it is easier to process than those made from conventional wood and metal materials, and therefore can be offered at low cost.
