Abstract
The utility model relates to computer host parts, in particular to a host built-in player applied on a computer host. The player is arranged on the computer host and is a 1.44 inches built-in player, and the player is internally provided with a horn and a play circuit board, wherein the horn is embedded on a shell of the player; the play circuit board is connected with an audio port of a host circuit board; and the rear end of the player is provided with a power interface connected with a host power supply. The player is mounted at a computer floppy drive interface or at a computer CD driver interface and has the benefits that: without being externally connected with a sound box, the player can play high-quality musical effect, not only occupies no place, but also facilitates moving; a user does not need to additionally purchase the sound box in a shop or a supermarket and arrange a plurality of audio connecting wires on a desk or the ground, thus saving place and power sockets. The player is simple in structure and strong in practicability, solves the defects of the existing computer host and saves cost.
Description
Technical field
The utility model relates to the host computer parts, refers more particularly to a kind of built-in player of main frame that is applied in host computer.
Background technology
Along with the continuous progress of society, industry-by-industry is all in develop rapidly, especially computer industry.
Four epoch have been experienced in developing into of computer so far altogether, and we are referred to as " electron tube computer age " to this section period from the nineteen forty-six to the nineteen fifty-nine.What the inner member of first-generation computer used is electron tube.Because a computer needs several thousand electron tubes, each electron tube all can distribute a large amount of heats, and therefore, how to dispel the heat is a headachy problem.The longest-lived of electron tube has only 3000 hours, usually takes place during computer run owing to electron tube is burnt out the phenomenon that makes computer corruption.First-generation computer is mainly used in scientific research and engineering calculation.
From nineteen sixty to 1964 year, owing in computer, adopted the transistor more advanced, so we are called " transistored computer epoch " period with this section than electron tube.Transistor is more much smaller than electron tube, does not need warm-up period, and consumed energy is less, handles rapider, more reliable.The program language of second-generation computer from the machine language development to assembler language.Then, high-level language formula translation and cOBOL language develop in succession and are widely used.At this moment, bring into use Disk and tape as additional storage.The volume and the price of second-generation computer have all descended, and the people of use is also more and more, and computer industry develops rapidly.Second-generation computer is mainly used in commerce, Teaching in University and government bodies.
From nineteen sixty-five to 1970 year, integrated circuit is applied to computer, so this section is called as " middle small scale integrated circuit computer age " period.Integrated circuit (Integrated Circuit is called for short r) is a complete electronic circuit that is made on the wafer, and this wafer is also littler than finger nail, has but comprised several thousand transistor units.The characteristics of third-generation computer are that volume is littler, price is lower, reliability is higher, computational speed is faster.The representative of third-generation computer is IBM 360 series that IBM Corporation has spent 5,000,000,000 dollars of exploitations.
From 1971 till now, be referred to as " large scale integrated circuit computer age ".The element that the fourth-generation computer uses still is an integrated circuit, but, this integrated circuit improves greatly, it is comprising hundreds of thousands to up to a million transistors, people are referred to as large scale integrated circuit (LargeScale IntegratedCircuit, be called for short LSI) and very lagre scale integrated circuit (VLSIC) (Very Large Scale Integrated Circuit is called for short VLSI).1975, U.S. 1BM company released personal computer PC (PersonaI Computer), and from then on, people are no longer strange to computer, and computer begins to be deep into human lives's various aspects.
Present desktop computer all is made up of main frame and display, and puts the music on or just need external speaker during sound at needs.And generally also need to the shop when in needs, using or the supermarket is bought back, and then be placed near the computer, connect use with tone frequency channel wire and power line.This mode hell to pay, the one, need purchase audio amplifier again, the 2nd, various lines are many, and the wiring inconvenience is more inconvenient in office or some Conference Rooms.
Based on the weak point of above-mentioned existing host computer, the inventor has designed the utility model a kind of " the built-in player of main frame ".
The utility model content
The utility model at above-mentioned the deficiencies in the prior art technical problem to be solved is: provide a kind of main frame built-in player.
The technical scheme that its technical problem that solves the utility model adopts is:
The built-in player of a kind of main frame, be installed in host computer, described player is 1.44 cun built-in players, be provided with loudspeaker and playback circuit plate in the player, these loudspeaker are embedded at the shell of player, the playback circuit plate is connected with the audio port of host circuit board, and the rear end of player is provided with and is used for the power interface that joins with host power supply.The utility model is installed in computer floppy drive interface position, also can be installed in the Computer optical disc drive interface position.
The described player outside is fixed at the floppy drive position or the CD-ROM drive position of host computer with screw.
The rear end of described player is provided with audio input interface, audio output interface.
The front end of player is provided with the audio amplifier control button.
The beneficial effect of the built-in player of a kind of main frame of the utility model is:
Do not need external speaker, just can play out the music effect of comparison high-quality, neither occupation of land side is convenient to again move.Solved the problem that does not have playback set on the existing main frame, the user does not need additionally to go shopping again or audio amplifier is bought in the supermarket, place many audio connecting cords on the ground nor need reach on the table, save local, save electric power plug socket, the utility model features simple structure has solved the weak point of existing host computer, practical, save cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an overall structure perspective view of the present utility model;
