Portable portable speakers gave me the impression that they were relatively general. Basically, the compact and compact sound quality kept up. The sound quality was relatively good and the experience was relatively large. Of course, it was not without their own ideal product, but the price was quite touching. That expensive deters you. This time, I received this multi-function Bluetooth speaker from the Longines M600. Not only did it make me unexpected in terms of sound quality, but it was also sincere in terms of price, which enabled me to have a new understanding of this handy portable Bluetooth speaker.

Long Qin M600 packaging simple and generous, only a large physical map printed in the middle, the amount of information on the back of the packaging is quite large, the basic functions of the Long Qin M600 are basically listed, and the basic Bluetooth speaker is basically nothing Big difference, but I like the folder function most. I can classify different types of songs and listen to different music in different moods.
Long Qin M600 family portrait: Long Qin M600 host a charging data line, a speaker cable and instructions.
When we took the Lumqin M600 at the beginning, it was 250mm147mm69mm in size. We must see this specification and we must also feel that this brick is really small, and it's quite worthy of being hand-held. Of course, there is such a weight of Longqin M600, which consists of a positive 3 Inch woofer and two 2-inch full-range speakers, the reverse side is composed of two 9060mm passive units, the built-in battery reaches 8800 mA.
The front panel net is woven with new waterproof splash nylon fiber yarn. The touch on the hand is quite good. The leather hand strap and the sewing threads on both sides make the product look like a high grade. There is also a LOGO of the langqin on the hand strap, and every detail is quite good.
The operation controllers of the Long Qin M600 are all concentrated on one side of the speaker. I will not introduce them one by one. The operation is the same as that of ordinary Bluetooth speakers. Here I would like to talk about folders and mobile power charging modes. It is one of my favorite functions in the Longines M600. It can classify different types of songs and listen to different music in different moods. The Longmother M600 supports charging digital devices, allowing Bluetooth speakers to change their mobile power in seconds.
In addition to the top operating buttons on the side of the fuselage there are several interfaces are as follows: Micro SD card, power switch, AUX audio interface, Micro USB charging interface, standard USB interface (output voltage is 5V-2A).
The Long Qin M600's connection mode is very diverse. It has an AUX wired audio interface, and can also be used as an external playback device via a wireless Bluetooth connection. It can also be used as an extension of the TF card to become an MP3 player.
From this point of view, the langqin M600 is not a great stick. The design is simple and generous. It is a little Apple's design concept. No design is the best design. .
At the bottom of the lang piano M600 there is a whole piece of non-slip rubber pad, which can effectively prevent the displacement and tremor. Compared to some speakers using only four small mats, this is quite kind.
Audition experience is as follows: Bluetooth connection should be the most used way of the Longines M600, and my main experience is mainly this way. Of course, if you want better music quality, you are recommended to use TF card expansion to import and import the lossless music format. Let Langqin M600 play the greatest musical charm.

The Lombok M600 has a 3-inch woofer on the hardware. The first thing I listen to is Tsai Chin’s ferry. The treble M600 gives Tsai Qin’s unique vocal performance an incisive picture. The bass is euphemistically thick and powerful, and the midrange part is also quite impressive. Stick, people are immersed in that situation for a long time.

The second of the audition is Faye Wong’s “The Skyâ€. Her singing voice is light and bright. She likes to sing some melodious melody in particular. Listening to her singing makes her feel very relaxed and natural. The interpretation of the wind is quite outstanding, and Faye Wong's light and sound lines are all expressed.
In the past few days of experience, the greatest impression I ever had on the Longines M600 was my long life. I was also pleasantly surprised by the performance of playing music. A small voice squeaked into a powerful voice and the bass performance was tri-band. In the most outstanding, if you want to pick a thorn to the harpsichord M600 is not FM function, if you can add this radio function, then it is even more perfect.
An Internal PCB (Printed Circuit Board) Antenna is a type of antenna that is integrated directly onto the surface or embedded within the layers of a printed circuit board. This design approach offers several advantages over traditional external antennas, making it a popular choice for modern electronic devices such as smartphones, tablets, laptops, and wearable technology. Internal PCB antennas are a versatile and efficient solution for modern electronic devices. Their space-saving design, durability, and performance characteristics make them an attractive alternative to traditional external antennas.
Key Features and Advantages of Internal PCB Antennas:
Space Efficiency: Internal PCB antennas eliminate the need for a separate antenna housing, freeing up valuable space within the device. This is particularly important in compact devices where every millimeter counts.
Aesthetics: By hiding the antenna within the PCB, manufacturers can create sleek and seamless designs that are visually appealing. This enhances the overall user experience and makes the device more attractive to consumers.
Durability: External antennas are prone to damage from impact or environmental factors. Internal PCB antennas, on the other hand, are protected by the device's housing, reducing the risk of damage and increasing the device's overall durability.
Performance: Modern internal PCB antenna designs are highly optimized for specific frequency bands and can achieve excellent performance characteristics, including high gain, low noise, and wide bandwidth.
Integration Flexibility: Internal PCB antennas can be easily integrated into the device's PCB layout, allowing manufacturers to customize the antenna's position, orientation, and size to suit their specific needs. This flexibility also facilitates the integration of multiple antennas for MIMO (Multiple Input Multiple Output) systems, enhancing data throughput and reliability.
Cost-Effectiveness: While the initial design and engineering costs of internal PCB antennas may be higher than those of external antennas, the overall cost savings achieved through space efficiency, reduced material usage, and simplified manufacturing processes often make them more cost-effective in the long run.
Types of Internal PCB Antennas:
Planar Inverted-F Antenna (PIFA): A popular choice for mobile devices, PIFA antennas are compact and offer good performance across a wide range of frequencies.
Chip Antennas: Small, low-profile antennas that are designed to be mounted directly onto the PCB. They are ideal for space-constrained applications.
Monopole Antennas: Simple, single-element antennas that can be embedded within the PCB or mounted on its surface.
Meandered Antennas: Antennas with a complex, serpentine-like shape that allows them to fit within a small area while maintaining good performance.
