The bagpack built in multiple use portable audio amplifier in belt strap}

The present invention relates to a portable bag equipped with a multi-purpose portable audio amplifier in a bag strap, and more specifically, a speaker and an amplifier are integrally formed without the inconvenience of a user carrying a portable audio device such as a radio, an MP3 or a CD player separately from a bag. The user can easily listen to music through the speaker while walking, hiking or traveling by simply attaching a small, lightweight, portable audio amplifier to the shoulder strap of the bag. A portable equivalent bag equipped with a significantly improved mobile audio amplifier.

In general, a radio, an MP3, a CD player, etc. are small and light portable audio devices that a user can carry in a special case, a bag or a pocket, and can output and listen to voice or sound while using headphones or earphones.

However, in order to listen to music or information using the above-mentioned audio equipment during hobby activities such as jogging, walking, and sports, or attaching it to the belt by using a special case, or attaching it to the user's clothes pocket or hand bag It is inconvenient to carry, store and operate, and can not listen to external sounds because it should be put in a briefcase, a backpack or a backpack with a shoulder strap, and worn while wearing headphones or earphones. The lines are exposed and the appearance is messy and there is a problem that can be entangled, twisted or cut.

In recent years, as the fashion is diversified, a backpack-type backpack that can be easily carried on both shoulders or carried in the hands by using a shoulder strap for students or hiking backpacks during high school is popular. The backpack is usually made of a material such as fabric, synthetic resin, leather, etc., and is formed by a body formed with a space that is opened and closed by a cover so that the article can be stored inside. As it is formed as a space, stable mounting of the acoustic equipment is difficult and there is a risk of damage or breakage due to the contact with other items due to flow during movement.

As a prior art that solves the above problems, Korean Patent Office Registration Utility Model Publication No. 20-0191584 "Bag" (notice date: 2000.5.26) is attached to the speaker and the amplifier under the storage space of the bag is sent out from the CD player, etc. It is a configuration that allows you to listen to sound through speakers or earphones. The speaker, amplifier, and CD player can be fixed or accommodated in separate storage pockets or uppers so that they can be carried safely without the risk of damage due to flow. It is convenient to store due to the built-in light, but there is a problem that the structure is complicated and difficult to operate because the bulky sound equipment is separated and arranged, and also the Korean Patent and Trademark Office Utility Model Registration No. 20-0314635 No. "Bag" (Notice date: 2003.5 .15) a backpack-type backpack with a shoulder strap, in which a sound device and a battery are attached to one side of the body as the main equipment; Speakers and controllers, which are peripheral devices, are installed inside the shoulder strap and are electrically connected to each other. Since the speaker is built in the shoulder strap, there is no need to use separate earphones or headphones. It is convenient to carry and store, but it is not integrated, so each device of the device is distributed and the structure of the bag is complicated, which reduces the storage space of general belongings and lacks the expandability to amplify and output the input of various voice source sources. Therefore, only a limited use of the device can be used, and there is a problem in that it is inconvenient to carry separately.

And the bag with the amplifier of the prior art is a dedicated bag in which the sound device storage unit is formed in advance and a fixed sized sound device is fixed, so it does not matter when carrying the bag at all times, but it is used in a state where the dedicated bag is not used. This is impossible and there is a disadvantage in that the portability is inconvenient to carry and lack of expandability with other audio equipment.

As a result, as described above, the built-in bag for the acoustic device according to the prior art is difficult to install because the sound device and the speaker are separated, and in particular, the main body of the device is large and heavy, so that it is impossible to attach it to the suspenders. There is a fundamental and comprehensive problem that cannot be provided with various sound sources because it is not expandable with sound equipment.

The present invention has been made to solve the above-mentioned problems, and is a compact, lightweight and easy to move and carry so that it can be attached to a shoulder strap to form a speaker integrated audio amplifier combined with a speaker and an amplifier, and easy to operate even while wearing a bag Built-in speaker integrated audio amplifier storage pocket formed on the string or detachable external type, so that you can easily listen to music through the speaker during walking, hiking, traveling, etc. It is an object to provide a portable equivalent bag.
