The present invention relates to a portable speaker device that can be easily gripped on the shoulder strap or forearm of a bag during sports or outdoor activities such as roller blades, cycles, hiking, or fishing. Not only can be used as a small capacity speaker, but also relates to a rechargeable portable portable speaker device that can be used in place of a headphone.

In the second half of 2005, Christopher Capuano, a professor of psychology at Fairy Dixon University in New Jersey, USA, surveyed overweight or obese women at an annual conference on obesity in Vancouver, Canada. It has been shown to be more effective in reducing weight and body fat.

On the other hand, research on "exercise effect of dance sports" indicates that dance sports have been medically proven to be effective as a fitness exercise for the purpose of health.

In the above study, the exercise effect through dance sports is briefly shown that the amount of energy consumed by an average adult woman dancing for one hour a day corresponds to about one fourth of the calorie consumed per day. For example, if a person weighing 60 kg sits still, the energy required per hour is 0.021 kcal × 60 minutes × 60 kg = 76 kcal. × 60 minutes × 60 kg = 605 kcal, or about 8 times more. For reference, 530kcal (605kcal-76kcal = 529kcal) is about one quarter of the 2,000kcal calories that an average woman consumes per day. You can see how big the impact is. In addition, it can be seen that the tendency of taking music into sports is prominent in sports as in Tae Bo (combination of Taekwondo and boxing).

Judging from the above fact, it is clear that listening to music while exercising increases the exercise effect, and it is judged to be particularly effective in simple repetitive exercise such as walking exercise and running exercise for health.

Hereinafter, the prior art related to the present invention will be briefly described with reference to FIGS. 1 to 4.

1 is a view showing the configuration of a conventional computer speaker device, Figure 2 is a circuit diagram schematically showing the circuit configuration of the speaker device shown in Figure 1, Figure 3 shows the configuration of a conventional earphone device 4 is a diagram showing the configuration of a conventional headphone device.

As shown in Fig. 1, a general computer speaker device generally uses a small output amplifier of 10 W or less, and is composed of left and right sound speaker devices L and R to add stereo functions. It can be seen that the front of the speaker is composed of a power switch 11, volume switch 12, AC input power 14, audio jack 15.

FIG. 2 is a circuit diagram showing the circuit configuration of the speaker device 10 shown in FIG. 1, which is adapted for converting commercial power into a 5V DC power source, and sound in various formats such as mono and stereo. It can be seen that a microprocessor 16 for regeneration is mounted on the PCB substrate.

3 is a diagram exemplarily illustrating earphones for reproducing sound of a portable audio device such as an MP3, an iPOD, or a mobile phone.

The earphone device 20 shown in FIG. 3 has a size such that a playback unit 21 including a microphone can be inserted into a human ear hole, and an audio jack 23 is provided at the end of the connection harness 22. It is installed.

FIG. 4 exemplarily shows a headphone 30 which can be worn by a user of a telephone and an acoustic device in a head, and in general, the headphone is located outside the ear wheels unlike the earphone in the ear hole shown in FIG. 3. Although there are differences in that they are used in close contact with each other, the functions and circuit configurations are the same.

Here, there is a disadvantage that the computer speaker device 10 shown in FIG. 1 is not portable. On the other hand, while the earphone 20 and the headphone 30 shown in FIGS. 3 and 4 have the advantage of accurately reproducing the sound of an audio device, when the earphone and the headphone are used for a long time, hearing loss such as hearing loss may be caused. It can be seen that there is a research result. In particular, according to Harvard University medical doctor Brian Fliger, published in the journal Ear and Hearing, on average, smaller earphones produce higher levels of output, i.e. smaller earphones It is said to be more detrimental to the ear's nerves because it outputs 9 decibels louder than large headphones that cover the entire ear. In addition, Australia's National Hearing Research Institute surveyed 18-54-year-old portable audio equipment users found that nearly one-third of respondents enjoyed music at a level that could cause hearing damage in the long run. .

In addition, when exercising, such as inline, skiing, boarding, cycling, and listening to music through the earphones in many cases. In this case, since no external sound can be heard at all, there is a case in which a horn sound or the like cannot be heard in the rear, leading to a safety accident.
