In addition, light emitted from the lighting module 70 installed between the case 10 and the cover 16 is spaced in the case 10 through the transparent cover 17 installed on the arch surface 10b of the case 10. It spreads in the up-down direction of 10a) and the case 10.

By the light emitted from the lighting module 70, the case 10 is used as an indirect illumination at the same time feels a beautiful aesthetic.

As illustrated in FIGS. 7 to 13, the sound transmitted through the speaker of the smart phone installed in the horn member 20 is amplified while gathered through the sound hole 21a of the horn 21, and the amplified sound is the case 10. Reflected on the arch surface (10b) of the () is sent out in the upper direction and the lower direction of the case (10).

And through the sound-absorbing member 40 is installed in the case 10 has the advantage that you can hear the cleaner sound to the user by sending out the job contained in the sound.

In addition, the sound is split by the peak preventing member 50 installed in the case 10, the split sound can prevent the high-pitched collision to the maximum as possible, the user can hear a more clean and clear sound have.

In addition, the light is emitted in the up and down direction and the space portion 10a of the case 10 by the lighting module 70 installed in the case 10, the overall aesthetics feel beautiful as well as indirect lighting Because it can be used, the user has the advantage of relaxing in a comfortable state.

As shown in FIG. 14, the speaker for a smartphone according to the present invention configured as described above uses an iPhone produced by Apple as a model and transmits sound to the smartphone alone using the speaker for a smartphone according to the present invention. Data on audio band, amplification characteristics, and original frequency response characteristics when sound was amplified were compared.

First, when sound is transmitted through the speaker installed in the iPhone, it can be seen that the sound energy is concentrated in the midrange.

In other words, the performance of the speaker itself is low, so the sound bands can be seen to be concentrated in the mid-range of 700 ~ 800Hz rather than made even.

However, when the sound is reproduced while the iPhone is mounted on the speaker for the smartphone of the present invention, it can be seen that the characteristics of uniformity and amplification of the entire audio band, and the overall audio amplification characteristic also has an amplification ability of at least 10 dB or more. It can be seen that it appears.

In the case of the high frequency, it can be confirmed through the graph shown in FIG.

In addition, the frequency response characteristic has an even amplification effect up to 500-5000 Hz, which also has a relatively uniform frequency response characteristic.

As described above, the smart phone speaker according to the present invention has an advantage of providing sound characteristics that can only appear in expensive speakers (using electricity) even with only the sound of the smart phone itself.

As mentioned through an embodiment of the present invention, when amplifying the sound of the smart phone itself, the sound transmitted from the smart phone is amplified without a separate power source or an electronic system for amplifying the sound. In addition, the peak phenomenon that may occur during the prevention of occurrence also has the advantage that the user can amplify the sound better.

In addition, if the sound transmitted from the smartphone is adjusted through the volume control function of the smartphone itself, the speaker of the present invention is also adjusted according to the volume, so the user has the advantage of listening to the sound by selecting his or her desired volume, Since the size can be configured larger or smaller, there is an advantage that the user can select the desired size.

In addition, since only a charging jack for charging a smartphone is installed and a speaker for amplifying sound is not installed, there is an advantage of providing an environment-friendly product to a consumer.

In the detailed description of the present invention described above with reference to the preferred embodiment of the present invention, the scope of protection of the present invention is not limited to the above embodiment, and those skilled in the art of the present invention It will be understood that various modifications and changes can be made in the present invention without departing from the spirit and scope of the invention.
