This time, I will explain the audio aspects of the Xperia 5 III and I was able to listen to it for a short time, so I will deliver the first impressions. do.
The evolution of the Xperia 5 III in terms of audio is that it has the same technology as the Xperia 1 III in terms of earphone output, and the sound pressure has been improved by 40%. By reducing the distortion applied to the low frequencies, the sound became clearer than the Xperia 5 II.
The earphone jack is located on the top of the main unitWhen I actually listened to it, the cymbals sounded in the bass of the drum kick and bass sounded sharper on the Xperia 5 III, and various instruments were heard. In scenes that seem to be jumbled together, the sounds of each instrument can be heard more separated, and the sense of resolution has increased.
However, the difference is not that big. It was the same with the Xperia 1 II and Xperia 1 III, but processing to remove distortion that cannot be heard by human hearing has been applied, and the effect seems to have slightly increased the resolution. It is said that So, the most obvious change would be that the sound quality is better and you can now enjoy it even at a higher volume.
There is no mention of a 40% increase in sound pressure for the main unit speaker, and as far as the specs are concerned, it seems that there is no change, but this has also been adjusted and the sound quality has improved. Although there is no change in hardware, processing has been performed to bring the sound quality closer to that of the Xperia 1 III by tuning.
Since the speaker unit emits sound vibrations to the front and also to the rear, when sound is emitted from the smartphone's speaker, the rear panel of the smartphone receives it and vibrates. If you actually hold your smartphone sideways and make a sound and raise the volume, you will notice that the vibration is transmitted to your hand.
In the Xperia series, the vibration transmitted to the rear panel is reduced by placing the lower speaker in a special enclosure when the main unit is held vertically. The extra sound emitted by this vibration was prevented, but in the high-end model Xperia 1 III, the opposite side, that is, the upper speaker when the main unit is held vertically, also has a dedicated enclosure in the same way. By providing it, the vibration of the rear panel due to resonance was further reduced, realizing clear sound quality.
On the other hand, the Xperia 5 III this time could not introduce the same mechanism as the Xperia 1 III due to the body size. Therefore, we improved the sound quality of the Xperia 1 III by reducing the band where the entire rear panel resonates the most by tuning without changing the hardware.
When I hear that some bands are reduced, I think that the balance of the overall sound will change, but even if I listen to and compare the previous model Xperia 5 II and Xperia 5 III, the treble and I don't feel much change in the overall nuances of the sound, such as the bass being more prominent, or the midrange being stronger and the vocals becoming more prominent.
With the sound creation in the same direction, the Xperia 5 II has a vague guitar sound, and the bass and drum bass and drums have the impression that the sounds are mixed, but the Xperia 5 III is clear. , and the impression is that the sounds of the instruments are clearly separated and layered.
The sound emitted by the vibration on the rear panel side has a lot of vague bass components. By minimizing this occurrence and slightly enhancing the low frequency range emitted from the speaker, the low frequency range with low resolution due to vibrations in the past was replaced with the low frequency range with high resolution emitted from the speaker. The result is a clear sound.
If you actually play music while holding the device in your hand, you can easily see the difference in vibration. The previous model Xperia 5 II not only shakes the entire rear panel, but also feels a strong vibration from the center of the rear panel.
With the Xperia 5 III, which was tuned to reduce this vibration, I felt a little vibration from the upper side of the body when held vertically, and almost no vibration from the lower side.
With these adjustments, although it is not possible to update the sound quality by installing an enclosure, it is said that it was possible to bring the sound closer to the sound of the high-end model just by tuning.
