HomePod ! Apple再度做喇叭!

正在寫CD這個音響革命來自於圈外人,Apple就出招了...
https://www.apple.com/homepod/

這個該是要和Amazon那個語音介面拼,體型很小,直徑只有142mm,當然可以唱音樂,顯然也不會太好,不過,台灣的那一堆鵝蛋喇叭會直接bye bye...
我說,Apple又做這種學他人招數產品,真的不太妙...


結構上,頂部一個低音,側面七個高音,這當然是為了讓你在房間裡各處都聽的清楚,高音有指向性,不過,七個這數字有意思...或許是精算過擴散角吧...



HomePod uses an advanced algorithm that continuously analyzes the music and dynamically tunes the low frequencies for smooth, distortion‑free sound.

這有意思!正是我最近在思考的題目,單體唱不出來的頻率最好砍掉,HomePod裡有個超強的A8能輕易搞定這點,厲害的是dynamically tune這點...

還加上echo cancellation不知道做啥...

Place HomePod anywhere in the room. It automatically analyzes the acoustics, adjusts the sound based on the speaker’s location, and steers the music in the optimal direction. Whether HomePod is against the wall, on a shelf, or in the middle of the room, everyone gets an immersive listening experience.

這該是控制那七個高音吧...這很難做...聆聽位置不定,麥克風又沒擺在聆聽位置...

Put another HomePod in the same room, and the two automatically detect and balance each other — for sound that’s even more lifelike.
我猜是時間延遲...同樣,聆聽位置不定,難做...

又AirPlay 2...

總結
High-excursion woofer with custom amplifier
呃... 以Apple的財力來搞,HiFi廠商不妙...
Array of seven horn-loaded tweeters, each with its own custom amplifier
號角!超小的號角!
Six-microphone array for far-field Siri and room sensing
Internal low-frequency calibration microphone for automatic bass correction
這有意思啊...不知怎麼做的...
Direct and ambient audio beamforming
不懂...
Transparent studio-level dynamic processing
這個有意思...挺實用,單是應付每曲動態都不同就很值得,而且這麼小的喇叭一定得要處理。

就生意面而言,US$350會讓二萬以下的音響都全部直接死掉,然而這東西本質上就不是個音響,雖然對多數人而言音響功能充足,而是個語音介面,取代前幾年喊了很久卻放棄的"Apple TV",以我常說的,就是科幻電影裡那個太空船主電腦,也就是電腦管家;
說這東西本質不是音響,是因為其本質是Siri,因為Siri要講話,有個喇叭,所以順便放音樂,如此而已,其體積/價格已限制其音質;
就我HiFi業者而言,我思考的是,未來有沒有可能延續搭iTunes順風車這種方式,搭Siri+HomePod的順風車將音樂數位轉到HiFi系統上?
