The high-frequency loss will be relatively serious. When using the laptop normally, the bigger "voice cabinet" spread sounds downward to the table, and the sounds will get reflected. According to the subjective hearing experience, Macbook Pro doesn't have a strict audio frequency distribution. The subjective hearing experience would be worse apparently only when the frequency up to 8kHz, and the worsening is not so heavy-the speaker is put there only to enrich the details of high-frequent sounds. Judged through subjective hearing, although Macbook Pro with Touchbar has already been equipped with a treble speaker, the lower speaker also has a good extension for treble. But don't forget about the long openings on two sides which become the main force to spread sounds instead. According to the actual use, it would still make specific influence on high-frequent audios to cover the whole area of holes (in the lower part) with hands (in fact the influence is much smaller than the Macbook Air keyboard covered by the protective film). Through the step-by-step teardowns by ifixit, we can easily understand the new design of the Macbook Pro's speaker configuration, namely the new design of inside voice boxes. As is shown in the picture, there is still a speaker near the holes' center, which takes charge of treble. This time, the 2017Macbook Pro 13 Retina with Touchbar is almost the same with the 2016 version for the inside design, except for aspects like CPU and SSD.Īccording to the actual experience, maybe 90% of those holes' function is truly for decoration. The most influential updating embodies the brand new cooling system, the CPU with a better initial configuration£¬SSD via PCI-E£¬and certainly a new loudsperker system. The renewal includes completely-newly designed circuit board, cooling system and battery layout (the new product has a smaller and lighter battery). The significance of Touchbar does not lie on how useful the OLED touch keyboard, but that its inside design is completely different with the shortcut keys version (retina Pro 13 without touchbar).

In 2016, the Apple Macbook Pro 13/15 retina with Touchbar is the first Macbook Pro laptop which is totally updated in terms of design (Noted: Both 13 inches and 15 inches refer to the diagonal length of the screen whose unit is inch, written for short as customary). Original Chinese version was released at 2017.9.11.
