Bose SoundLink Home Disassembly #Actions ATS2835P

As one of the earliest speaker manufacturers in the world, Bose has gradually grown into a large multinational company that occupies a leading position in the research and manufacturing of top-level audio and acoustic systems through its unremitting exploration and innovation in the field of audio. Bose has a very rich product line, including speakers, headphones, earbuds, Bluetooth speakers and home entertainment systems, which meet the diverse needs of different consumers for sound quality.

Recently, Bose's classic SoundLink series of Bluetooth speakers has been updated again. Bose SoundLink Home brings a double enjoyment of hearing and vision to the home space with a new attitude and classic outstanding sound quality. Its appearance is smooth and elegant, which can better integrate into various home environments and add a touch of style to life. In terms of functional configuration, Bose SoundLink Home is equipped with a full-range driver unit and a dual passive diaphragm design, which brings clear and transparent sound and deep bass; supports Bluetooth and USB-C audio inputs to meet the needs of different music devices; supports double-click parallel connection to present a more three-dimensional shocking sound effect; and also has a built-in microphone to support voice calls and voice assistants. At the same time, the battery life is up to 9 hours.

The Bose SoundLink Home packaging box adopts a family-style design style. The front is divided into two parts by the BOSE brand logo. The top shows the product details and the bottom shows the overall appearance.

The front appearance of Bose SoundLink Home adopts a "floating" design. The one-piece aluminum alloy bracket is processed with anodized aluminum brushed process. The body is covered with a high-quality cloth mesh cover and matched with warm wood color. It has outstanding texture and is very stylish.

Function buttons are set on the top of the body for controlling various functions.

Through unboxing, we have a detailed understanding of the new appearance design of the Bose SoundLink Home Bluetooth speaker. Now we will enter the disassembly part to see the internal structure configuration information.

Actions ATS2835P is a highly integrated Bluetooth audio SoC chip with Actions' low-latency and high-quality sound technology. ATS2835P integrates Bluetooth controller (including RF and baseband), power management unit, audio codec and other modules; supports Bluetooth 5.4, LE Audio, with a latency as low as 20ms, two-way high-definition voice transmission, multi-channel wireless transmission, and coexistence of classic Bluetooth and LE Audio; supports full-format audio decoding and rich audio post-processing technology, so that the sound has a higher degree of restoration and fidelity. ATS2835P also supports the Audio broadcast function, and is one of the earliest manufacturers in China to implement the Bluetooth one-to-many audio broadcast protocol. The protocol supports simultaneous audio streaming from one Bluetooth source to multiple speakers. This function is widely recognized by users in the European and American markets.

TI Texas Instruments BQ25611D charging IC is a highly integrated 3A switch mode battery charging management and system power path management device for single-cell lithium-ion batteries and lithium polymer batteries. The solution highly integrates input reverse blocking FET (RBFET, Q1), high-side switch FET (HSFET, Q2), low-side switch FET (LSFET, Q3) and battery FET (BATFET, Q4) between the system and the battery. Its low-impedance power path optimizes the efficiency of switch mode operation, shortens the battery charging time and extends the battery operation time during the discharge phase.

SGMICRO SGM6612A is a 20V high-efficiency synchronous boost converter that integrates two 15mΩ power switches with a switching frequency of up to 2.2MHz and programmable resistors. The device provides a small-size power solution for portable devices. SGM6612A has two operating modes, pulse width modulation (PWM) mode and pulse frequency modulation (PFM) mode. PWM mode is suitable for medium to heavy loads. PFM mode is applied at light loads to improve efficiency.

The new appearance design of the Bose SoundLink Home Bluetooth speaker is very distinctive. The hollow suspended structure, the metal bracket treated with anodized aluminum brushed process, the high-quality cloth mesh, and the warm wood color all reveal the style. While enjoying the music, it can also serve as an ornament to decorate the interior space. In terms of the main internal configuration, it uses a 3100mAh cylindrical 18650 lithium battery, equipped with a full-range speaker unit + front and rear dual passive radiation diaphragms, a built-in microphone pickup, and the wireless connection uses the Actions ATS2835P Bluetooth audio SoC chip, which supports Bluetooth 5.4 and LE Audio, supports full-format audio decoding and rich audio post-processing technology, so that the sound has a higher degree of restoration and fidelity; it also uses the SGMICRO Shengbangwei SGM6612A synchronous boost converter, TI Texas Instruments TPA3136D2 audio power amplifier, etc.
