一种便携式无线音乐播放装置A portable wireless music player

技术领域：Technical field:

本实用新型涉及音乐播放产品技术领域，尤其涉及一种便携式无线音乐播放装置。The utility model relates to the technical field of music playing products, in particular to a portable wireless music playing device.

背景技术：Background technique:

多媒体播放系统，作为丰富人们文化生活的一种家电产品，已经越来越在生活中不可或缺，媒体播放系统也经历了电子管时代、晶体管时代和集成电路时代，媒体载体也从记录模拟信号的磁带过渡到记录数字信号的CD、DVD和数字存储器等，数字信号也由原来的1Bit发展到现在的20Bit和24Bit，但是这些信号经过媒体播放机解码、放大之后，都需要经过音频、视频电缆与音箱和电视机或者其它显示终端设备连接，电缆很多且长，错综复杂，很不美观，甚至需要进行预埋布线，虽然美观一些，但是也有移动不便、维护困难的弊端。随着无线传播科技的发展，这些科技成果也逐步应用到媒体播放领域，由于大部分无线频段都属于政府控制，不能应用于ISM和消费领域，只有少量的RF频谱留给ISM和消费领域应用而无需申请许可证，因此，无线传输在消费型领域的发展也局限于这些频段。在多媒体播放领域的无线传输，主要有以下三种：Multimedia playback system, as a kind of home appliance that enriches people's cultural life, has become more and more indispensable in life. The media playback system has also experienced the age of electronic tubes, transistors and integrated circuits. The media carrier has also changed from recording analog signals to Tape has transitioned to CD, DVD and digital memory that record digital signals, and digital signals have also developed from the original 1Bit to the current 20Bit and 24Bit. However, after these signals are decoded and amplified by media players, they need to go through audio and video cables and Speakers are connected to TVs or other display terminal devices. There are many and long cables, which are intricate and unsightly. Even pre-embedded wiring is required. Although it is more beautiful, it also has the disadvantages of inconvenient movement and difficult maintenance. With the development of wireless communication technology, these scientific and technological achievements are gradually applied to the field of media playback. Since most wireless frequency bands are controlled by the government, they cannot be used in ISM and consumer fields. Only a small amount of RF spectrum is reserved for ISM and consumer fields. There is no need to apply for a license, so the development of wireless transmission in the consumer field is also limited to these frequency bands. There are three main types of wireless transmission in the field of multimedia playback:

(1)低频传输系统：亦称为电磁感应式传输系统，是在听音范围内设环形线路，用大功率音频放大器馈电，产生较强的音频电磁场。听众使用由输入铁芯线圈和放大器推动的耳机收听。这种系统简单价廉，但音质和稳定性较差。由于低频电磁场能穿透一般建筑物，因而保密性较差，因此适合博物馆、科技馆和某些大型会议展览中心需要多个分会场同时使用同一套传输系统这种特殊情况使用，在个人消费及对信号质量和保密性要求较高的领域都难以应用。(1) Low-frequency transmission system: also known as electromagnetic induction transmission system, a ring circuit is set within the listening range, and a high-power audio amplifier is used to feed power to generate a strong audio electromagnetic field. The listener listens using headphones propelled by an input iron-core coil and amplifier. This system is simple and cheap, but the sound quality and stability are poor. Since the low-frequency electromagnetic field can penetrate general buildings, the confidentiality is poor, so it is suitable for museums, science and technology museums and some large-scale conference and exhibition centers that require multiple sub-venues to use the same transmission system at the same time. It is difficult to apply in fields that require high signal quality and confidentiality.

(2)红外传输系统：红外线(IR)是指波长超过红色可见光的电磁辐射，其频率在2MHz以上。红外线不能穿透墙壁，因此保密性佳，并能抵御无线电干扰和窃听，性能稳定且音质较佳，但是其不能穿透障碍物和需要定向传输的特性，以及其目前传输速率较低使其在多媒体无线传输领域的应用不具有优势。(2) Infrared transmission system: Infrared (IR) refers to electromagnetic radiation with a wavelength exceeding red visible light, and its frequency is above 2MHz. Infrared rays cannot penetrate walls, so they have good confidentiality, and can resist radio interference and eavesdropping. They have stable performance and good sound quality, but they cannot penetrate obstacles and require directional transmission. Applications in the field of multimedia wireless transmission are not advantageous.

(3)Bluetooth(蓝牙)技术：Bluetooth是一项由蓝牙专业组(SIG)制定的用于无线个人区域网络(WPAN)的新标准。Bluetooth是一种采用2.4GHz ISM频段的跳频协议。其保密性和传输速率都有不错表现，但由于其成本昂贵和功耗较大，使其在消费领域的应用受到制约。另外，随着媒体存储载体的样式增加，使得人们经常拥有五花八门的多种多媒体播放设备，造成管理和使用的不便。(3) Bluetooth (Bluetooth) technology: Bluetooth is a new standard for Wireless Personal Area Networks (WPAN) formulated by the Bluetooth Professional Group (SIG). Bluetooth is a frequency hopping protocol using the 2.4GHz ISM band. Its confidentiality and transmission rate have good performance, but its application in the consumer field is restricted due to its high cost and high power consumption. In addition, as the types of media storage carriers increase, people often own a variety of multimedia playback devices, causing inconvenience in management and use.

另一个方面，随着科技的发展，数码技术的不断更新，MP3等数字音乐播放器的出现，令传统的光碟播放器已经难以满足人们的需要了。目前最为流行的媒体播放器是：苹果公司开发的iPod、iPhone。iPod、iPhone是苹果推出的一种具有音乐播放功能的电子产品。另外，iPod、iPhone由于其属于便携式产品，其通常只能供个人使用，无法使用专业的播放器材(例如好的功放)播放。目前通常使用者在家中会将iPod、iPhone放置在一个音乐播放插座内，而这种播放设备固定在家里一个位置，无法根据使用者需要随意的移动位置。On the other hand, with the development of science and technology, the continuous updating of digital technology, and the appearance of digital music players such as MP3, it is difficult for traditional CD players to meet people's needs. Currently the most popular media players are: iPod and iPhone developed by Apple. iPod and iPhone are electronic products with music playing function launched by Apple. In addition, because iPod and iPhone are portable products, they are usually only for personal use and cannot be played with professional playback equipment (such as a good power amplifier). At present, users generally place iPods and iPhones in a music playback socket at home, and this playback device is fixed at a position at home, and cannot be moved at will according to user needs.
