Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, providing these embodiments is to be able to the more thorough explanation disclosure, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
Currently, onboard audio playing device mainly have three ways, such as it is following:
First way, FM music are that passive type listens to music, generate frequency in 88.5MHz- by FM radio frequency unit
FM frequency wave in 108.0MHz wave band, vehicle-mounted audio reception device receive frequency wave and will be converted to sound after frequency wave signal amplification
Frequency signal is realized and listens to music online.Although this kind of mode technology maturation, use cost are low, FM music is the receipts of passive type
It listens, right of the user without autonomous selection audio track, and compression ratio is quite high, traditional FM sound quality is 98Kbps, audio
It is second-rate, significantly constrain the result of broadcast of existing onboard audio playing device.
The second way, vehicle mounted MP 3 product are modern a trend product, are pursued by current many Fanciers,
Like.Gradually, money vehicle mounted MP 3, electric vehicle MP3 etc. is remotely controlled to start to replace traditional MP3.It is also designated as audio conversion simultaneously
Device, vehicle MP3 wireless transmitter or MP3 vehicle audio companion etc., it can form vehicle mounted MP 3 sound equipment with common MP3 player
System.Vehicle mounted MP 3 is able to achieve user according to oneself hobby, changes play list.But, it is necessary first to user downloads song
MP3 player is transferred into memory, then by memory.The above process needs to pass through more many and diverse operation, and user needs
Have certain computer knowledge, when especially a large amount of songs need to download, process will it is very dull with it is complicated, if necessary
The audio file of high-quality is looked for, then with greater need for the patient and time.
The third mode, CD (CD, Compact Disc), Mini Disk (MD, MiniDisc) player, although CD,
MD player etc. is able to achieve the music of high-quality, also saves very much the time, but with the development of digital audio, has been difficult
Find CD or Mini Disk again, while CD sells that there is also certain hysteresis qualitys, be not well positioned to meet people appreciate it is new
The needs of emerging music.
Obviously, there is certain limitation and deficiency in present vehicle-mounted music broadcast mode, easily user cannot be allowed to have
The music of high-quality is enjoyed.
Based on this, the relevant technologies provide a kind of onboard audio playing device, and user can operate touching according to the hobby of oneself
Control screen and key, select corresponding song or types of songs, onboard audio playing device passes through built-in forth generation mobile communication
The relevant music website of (4G) module accesses, music website transfer audio files are given to device, lead to after playing device coding and decoding
Satellite interface (AUX interface) output is crossed, realizes that high-quality music is appreciated online.
View of the above, it will be seen that in the related technology, back seat user can not directly click audio-frequency information to be played,
It is unable to satisfy the differentiation use demand of different user.
Based on this, the utility model provides a kind of multimedia playing apparatus, includes demountable host and terminal, host
It is embedded in vehicle seat rear backrest and fixes, and terminal part mainly includes audio and video module and can freely tear open with host
It unloads, is used for heel row user's independent operation, while terminal is communicated with host, user operates at the terminal, and at end
It completes to play on end, back seat user is facilitated to use.
Referring to Figures 1 and 2, the utility model provides a kind of multimedia playing apparatus, which includes
Host 2 and terminal 3；Wherein, the host 2 is embedded in the rear backrest 1 of vehicle seat；The terminal 3 and the host 2 are removable
Unload formula connection.
When practical application, the terminal 3 specifically may be embodied as handheld terminal, when using multimedia playing apparatus,
The terminal 3 can be placed on and use on hand by user, preferable and user-friendly using visual angle at this time, improve user's body
It tests.
Wherein, referring to Fig. 3, the host 2 includes controller 210, first communication module 211 and the first multi-media processing mould
Block 212；The terminal 3 includes: second communication module 310, the second multimedia processing apparatus 311；The controller 210 respectively with
The first communication module 211 and first multimedia process module 212 electrical connection；The second communication module 310 and institute
State the electrical connection of the second multimedia processing apparatus 311；The controller 210 passes through the first communication module 211 and described second
The communication connection that communication module 310 is established is interacted with the terminal 3；Described first under the control of the controller 210

It states to be additionally provided in plug 304 and is connect with the second source 313 and have the port of power transmission function.
When controller 210 determines the current connection state of the connector 201 and the plug 304 are as follows: the plug 304
When being not inserted into the connector 201, one kind is achieved in that: under the control of the controller 210, first power transmission
Device 217 emits AC signal, senses the hair on first power transmission device 217 in the second power transmission device 314
When the AC signal that emitter is emitted, the second power transmission device 314 is the terminal 3 progress using the AC signal detected
Wireless charging.Certainly, when practical application, may not be by host 2 is that the second source 313 charges, at this point, described second
It is second electricity using the AC signal detected when power transmission device 314 is detected from extraneous AC signal
It charges in source 313.
In some embodiments, the utility model embodiment multimedia playing apparatus further includes other function module, such as function
Rate amplification module is connect with loudspeaker 3111, improves output power, user-friendly.
It should be noted that the memory 213 in host 2 can be volatile memory or nonvolatile memory,
It may include both volatile and non-volatile memories.Wherein, nonvolatile memory can be read-only memory (ROM, Read
Only Memory), programmable read only memory (PROM, Programmable Read-Only Memory), erasable compile
Journey read-only memory (EPROM, Erasable Programmable Read-Only Memory), electrically erasable are read-only
Memory (EEPROM, Electrically Erasable Programmable Read-Only Memory), magnetic random are deposited
Access to memory (FRAM, ferromagnetic random access memory), flash memory (Flash Memory)；Magnetic
Memory surface can be magnetic disk storage or magnetic tape storage.Volatile memory can be random access memory (RAM,
Random Access Memory), it is used as External Cache.By exemplary but be not restricted explanation, many forms
RAM it is available, such as static random access memory (SRAM, Static Random Access Memory), synchronize it is static with
Machine accesses memory (SSRAM, Synchronous Static Random Access Memory), dynamic random access memory
Device (DRAM, Dynamic Random Access Memory), Synchronous Dynamic Random Access Memory (SDRAM,
Synchronous Dynamic Random Access Memory), double data speed synchronous dynamic RAM
It is (DDRSDRAM, Double Data Rate Synchronous Dynamic Random Access Memory), enhanced same
Walk dynamic random access memory (ESDRAM, Enhanced Synchronous Dynamic Random Access
Memory), synchronized links dynamic random access memory (SLDRAM, SyncLink Dynamic Random Access
Memory), direct rambus random access memory (DRRAM, Direct Rambus Random Access Memory).
The memory of the utility model embodiment description is intended to include but is not limited to the memory of these and any other suitable type.
In the instructions provided here, a large amount of concrete details are illustrated.However, it is to be understood that this is practical
Novel embodiment can be practiced without these specific details.In some embodiments, it is not been shown in detail
Methods, structures and technologies, so as not to dimmed understanding of this description.
