In today's era of rapidly developing entertainment technology, the need to own quality audio equipment to satisfy your passion for singing at home is increasing.

According to statistics from GfK Vietnam, the home entertainment audio equipment market grew by 32% in 2023, of which karaoke systems and portable speakers accounted for 65% of the total market share.

However, many consumers are still having difficulty choosing between these two product lines.

A karaoke system is a system consisting of speakers, amplifiers, karaoke players and wireless microphones, providing a professional singing experience with vivid sound. The signal is amplified and distributed through the devices, creating superior quality and high customization.

The portable speaker is an “all-in-one” device that fully integrates speakers, amplifiers, microphones, and rechargeable batteries in one box, making it easy to use and flexible. Sound is processed and emitted right inside, combined with a compact design and wheels for convenient movement in many spaces.

Karaoke systems have high performance, 90% fidelity sound, many features but are bulky and expensive. Portable speakers are compact, easy to move, cheaper but the quality and features are only about 60-70%.

Choosing equipment depends on space, purpose and budget: karaoke system is suitable for fixed use, specialized singing; portable speakers are suitable for small spaces, moving a lot.

This paragraph, Phuc Truong Audio will help you analyze the factors to choose the most suitable audio equipment.

What is Karaoke System? Structure and Operating Principle

A karaoke system is a specialized, flexible sound system, including devices such as speakers, amplifiers, karaoke players and wireless microphones, combined to bring a professional karaoke experience. During operation, the audio signal from the karaoke player is transmitted to the amplifier for amplification, then distributed to the speakers to reproduce the sound vividly and faithfully.

According to data from Phuc Truong Audio, karaoke system sales grew by an average of 20-25% per year in the period 2021-2024, showing that the demand for this device is increasing.

1. Karaoke system structure

A standard karaoke system includes speakers (bass, mid, treble), signal amplifier, karaoke player to store songs and wireless microphone for singers to move freely.

Loudspeaker: including subwoofers in charge of the 20-200Hz bass range to create depth for the sound, mid-range speakers handling the 200-2000Hz frequency range where the human voice is mainly concentrated, and treble speakers reproducing high sounds from 2000-20000Hz to bring clarity. High-quality speaker brands for karaoke systems include JBL (USA), Bose (USA), Paramax (Vietnam), and BMB (Japan) - each brand has its own characteristics in sound quality and is suitable for different music genres.
Amplifier: has the task of amplifying the audio signal and providing power to the speaker. Popular amplifier brands in karaoke systems include Jarguar (Korea) with good echo processing ability, Bosa with reasonable price, Arirang with high durability, and BellPlus with warm and detailed sound quality.
Karaoke player: is the control center and song storage, with a capacity of 4TB to 16TB, capable of holding from 50.000 to more than 100.000 songs of various genres. Some popular karaoke players such as VinaKTV, Hanet PlayX, BTE S9000...
Micros: Usually a wireless microphone so the singer can move freely. Wireless microphones with good sound quality include Shure UGX9, Bosa BS-8800, Zenbos 5200...

2. What is the operating principle of karaoke system?

The operating principle of a karaoke system starts with the user selecting a song on the karaoke player, creating a digital audio signal. This signal is converted into an analog signal through a DAC (Digital-to-Analog Converter), then transmitted to a digital reverb to process effects such as echo, reverb with a delay of 80-120ms to create depth for the vocals.

Next, the signal is fed into an amplifier to amplify the power, separate into different frequency bands and distribute to specialized speakers: the woofer handles the low frequency range, the mid-range speaker handles the mid-range frequency and the treble speaker handles the high frequency range. At the same time, the microphone picks up the vocals and converts them into electrical signals, which are processed through filters and amplified before being mixed with the background music, creating a harmonious and balanced sound.

According to Phuc Truong Audio's survey of 200 customers (2024), up to 90% of users highly appreciate the vivid and powerful sound quality of new karaoke systems.

What is a Portable Speaker? Structure and Operating Principle

The portable speaker is an 'all-in-one' multi-function portable audio device, designed with convenient wheels and handles, integrating speakers, amplifiers, karaoke players, wireless microphones and rechargeable lithium batteries in the same box.

This device is especially suitable for outdoor activities, picnics, events, parties and areas without stable power supply, featuring the ability to operate continuously for 4-8 hours on a full charge, high volume and high mobility. When operating, the audio signal from the source will be processed and amplified internally, then transmitted to the speaker system to produce clear and powerful sound.

1. Structure of portable speaker

The portable speaker integrates a speaker system (bass, mid-treble), Class D amplifier, multi-connection control circuit (Bluetooth, USB...), wireless microphone and lithium battery for continuous operation for many hours.

Speaker System: includes woofers, mid-treble speakers, dome or horn tweeters 1-2 inches. These speakers are integrated in the speaker cabinet with MDF or impact-resistant ABS plastic material, with a bass-reflex design with a bass reflex port to enhance the bass. Depending on the model, the configuration ranges from 2.1 (2 1-inch treble speakers + 1 10-inch woofer, total capacity 120W) to 5.1 (4 3-inch mid-range speakers + 1 1-inch tweeter + 1 15-inch woofer, total capacity 300W).
Class D Amplifier: is a high-efficiency digital amplifier (reaching 85-90% compared to 50-60% of traditional Class AB amplifiers), operating on the principle of continuous on-off (switching) instead of linear amplification. With a compact size of only 1/3 compared to traditional amplifiers with the same capacity, Class D amplifiers generate less heat, consume low power, and have the ability to respond quickly to signals with sampling frequencies from 200-500kHz.
Control circuit and connection: the system center uses a 32-bit ARM processor chip or equivalent, supporting a variety of connection ports such as Bluetooth, USB, memory card, FM radio... The control panel integrates an LCD or LED screen, allowing adjustment of volume, bass, treble, echo and other sound effects, along with a remote control or control application on a smartphone.
Microphone: Usually comes with 1-2 UHF (Ultra High Frequency) wireless microphones operating in the 600-900MHz frequency range for better anti-interference ability than old VHF technology.
Lithium battery: Modern portable speakers use high capacity Li-ion or LiPO batteries from 4000mAh to 20000mAh (depending on speaker size and capacity), providing power for the speaker to operate continuously for 4-8 hours at 70% volume or 10-12 hours at 50%.

2. What is the working principle of portable speakers?

When operating, the portable speaker operates according to a 5-step signal processing process:

Audio signals from the source (USB, Bluetooth, AUX...) are received and converted into digital signals via ADC (Analog-to-Digital Converter) if needed.
The signal is processed through a DSP chip to adjust parameters such as EQ, bass/treble enhancement, and balance between background music and vocals.
The processed signal is amplified through a Class D amplifier.
The amplified signal is split through an electronic crossover circuit for distribution to the appropriate speakers.
The speaker system converts electrical signals into sound waves. Users can customize a variety of parameters via the touch LCD screen or physical control buttons on the speaker body, including: separate volume adjustment for background music and microphone, EQ mode according to music genre, echo and reverb levels for vocals, bass-treble increase/decrease ±15dB, and select sound effects such as karaoke, party mode or concert mode.

A survey in January 1 by Phuc Truong Audio with 2025 people who bought portable speakers showed that 150% of users appreciated the easy mobility thanks to the sturdy wheels and handle, while 82% were satisfied with the quality of the included wireless microphone, especially the anti-howling ability and sensitivity when recording.
