Comparative results of sound quality of Apple homepod smart speakers
HomePod appearance
Homepod's appearance fabric is dense, almost pollution-free, not easy to get dirty, and it can also better reduce the damage of sound quality.
HomePod is equipped with an independent conical rubber pad at the bottom, aiming at eliminating unnecessary vibration to the maximum extent. In fact, the appearance and material design of HomePod have minimized the vibration, and the conical rubber pad has played more roles.
This component can be adjusted to a certain extent, thus changing the size of the sound cavity where the speaker is located. This fine-tuning effectively expands the adjustable range of tones in real time through a small component.
Compared with other models, it has better separation and bass response characteristics.
HomePod configuration
The specific configuration of HomePod as a speaker:
Built-in 7 speaker arrays and independent driving units;
Support beamforming and multi-channel echo cancellation;
Built-in A8 chip can realize real-time tuning through voice controller;
Can intelligently perceive the space, automatically detect the environment and adjust the sound.
HomePod's seven speaker arrays are distributed above the bottom of the fuselage, and a 4-inch woofer is arranged at the top. Similarly, HomePod has seven built-in microphones, six of which are used for Siri and the other is dedicated to helping Apple devices bass.
HomePod sound output principle
First, HomePod should model its room and use seven speakers to create a virtual sound beam. Apple included this process and applied for 200 patents for HomePod.
Finally, music is played according to this virtual sound beam, and in this process, the echo and other noises caused by wall occlusion have been eliminated. During the playback, both the speaker and the microphone are working, one is playing the sound, and the other is adjusting the sound.
HomePod research and development quality
Apple's process of developing smart speakers is very rigorous. Its largest testing laboratory is also one of the largest audio testing rooms in the United States, completely isolated from the outside world, without any audio pollution. Through various testing and engineering means, HomePod directly converts energy output into good output sound quality.
Comparison of sound quality between HomePod and other speakers
Apple's HomePod has a deep bass, rich treble and loud voice, which is enough to fill the whole room with excellent sound. Compared with its voice, the voices of Amazon Echo and Google Home are dull and insignificant.
Compared with Google Home Max, Amazon Echo and Sonos One have the "best" sound output from HomePod. It is exquisite and delicate, and the separation and clarity between various ranges are good.
For example, one has a good alto, but the treble is only a formal existence. When HomePod can keep balance, the sound quality of an output becomes harsh and painful.
From Echo to sono to Home Max, all other speakers can't output clear high and medium bass, which is what HomePod is good at.
HomePod even listens to the echoes reflected by various objects in the room to determine the appropriate audio output in the surrounding environment. All these processes are completed by A8 chip made by HomePod.
In addition, HomePod has an advantage over competitors: when users move HomePod, its built-in accelerometer can quickly perceive and adjust music and seamlessly connect; Sonos Tureplay takes 45 seconds to realize this process.
Bian Xiao abstract
HomePod creates a strong sense of existence, and you can feel the voice of HomePod in front of you. No matter where you stand, the applause and high notes will be projected from the speakers to the outside and around. This is one of the most stereoscopic sounds I have ever heard, and it is definitely the highest level of "single speaker". It is no exaggeration to say that HomePod is the most complex and interesting speaker among smart speakers.
