In recent years, with the popularization of intelligent terminals, the increase of audio usage scenarios, the improvement of consumers'requirements for sound quality, appearance and portability, and the development of audio and digital technology, audio products show the following trends:

(1) Miniaturization and Portability

With the rapid development of notebook computers, iPad/iPhone/iPod, tablet computers, flat-panel TV, smart phones and other new audio consumer electronic products, traditional audio has a trend towards miniaturization. Audio products are miniaturized. Users can carry them with them. They can be used in sports, travel, parties or other scenarios. They can get a better user experience than the speakers used to be peripherals of desktop computers and laptops.

(2) Wireless

With the change of sound source products, audio has been changing to adapt to new sound sources, such as from the traditional 3.5MM interface, RCA interface, USB interface to support the interface of iPod/iPhone/iPad Docking.

Bluetooth technology has been applied in practical products since 1998. In recent years, it has been gradually applied in the field of wireless audio. The new 2.4G wireless technology adopts automatic frequency hopping technology, which has stronger anti-interference, lower power consumption and longer transmission distance.

In recent years, the connection mode of audio products has expanded from early wired connection to Bluetooth, WiFi, NFC and other ways, such as Bluetooth wireless speaker, Wifi speaker, wireless SoundBar and so on.  Audio products through wireless connection to a certain extent improve the portability and ease of use of products.

According to the report of Transparency Market Research (TMR), in recent years, the market of wireless audio products, including Bluetooth speakers, wireless headphones, wireless microphones, car-borne wireless audio equipment, related APP applications, has entered a stage of rapid development. According to TMR data, the market of wireless audio products in 2014 is about 6.9 billion US dollars, and will grow to 38.5 billion US dollars by 2022, and from 2014 to 2022. The compound growth rate will reach 24%.

(3) Intelligence

With the development of digital technology, more and more new technologies are applied to audio products. Wireless audio, digital audio, digital power amplifier, digital audio center and other new technologies will promote the development of the speaker market. The speaker will change from a single playback device to a device that integrates multiple functions. Some products can even connect to the Internet to obtain music files directly from the Internet or listen to network radio.

In addition, in recent years, consumers have paid more and more attention to the conceptual design and appearance design of audio products. Even some consumers'demand for audio products may not only be for good sound performance, but also for decoration, which is far more significant than its own sound quality. This is particularly evident in the sports and outdoor markets. When buying audio products, these consumers will first pay attention to the appearance, not only the sound quality, but also whether they can meet their listening needs.
