Abstract
The utility model relates to an ear hanging earplug type receiver, the entirety of which can be plugged in ear holes and hung on auricles. The ear hanging earplug type receiver belongs to the technical field of radio reception. An antenna is arranged in a groove of the circumference of a circular arc-shaped casing; a special module for reception, a battery, a power switch, a tuning knob and a loudspeaker are arranged in the casing; all components are orderly and electrically connected to a printed circuit board and are tightly combined together in the structure. The utility model is a high tone quality miniature receiver which is difficult to separate from ears even if people move.
Description
(1) technical field
The utility model application case belongs to the radio reception technical field, refers in particular to ear-hang ear type receiver.
(2) background technology
The prior art relevant with this case is Chinese patent 92200434.X, and 92207819.X, also has the earphone receiver of Japanese REGUME company etc.These are many to be to have adopted straight system circuit variable L .C tuning manner, the uneven weakness of the big volume of noise is often arranged, and these receivers not that " extension " is exactly that " plug " listened in ear, because human body is walked about or collided, just fallen unless you give your whole attention to it, very not firm.
(3) summary of the invention
The present invention structurally overcomes to wear the not firm technical problem that comes off easily, and adopts advanced heterodyne system integrated circuit, and making becomes the light again miniature ear-hang ear type of the high tone quality receiver of the littler weight of volume.The utility model is for solving its technical problem, the technical scheme that adopts provides a kind of ear-hang ear type receiver, comprise antenna, receive special module, battery, mains switch, tune button, loud speaker, the set of printed circuit board (PCB) is in small outline package, it is characterized in that: placed antenna in the groove of garden arc shell periphery, soft-touch control has been arranged in the panel lower end, with convenient tuning, internal circuit adopts and receives special module in the shell, the hidden shell middle part that is installed in of mains switch, all electronic devices and components are electrically connected by a printed circuit board that is placed on outer casing bottom.The beneficial effects of the utility model are: compact conformation, and difficult drop-off during motion, tonequality is good, and volume is even, operates tuning convenience, and in light weight, volume is little, and it is also convenient to make.
(4) description of drawings
Fig. 1. be ear-hang ear type receiver longitudinal profile left side apparent structure figure.
Fig. 2. be the utility model front structural map.
Fig. 3. be the application circuit figure that receives special module.
(5) embodiment
With reference to Fig. 1 structural map, can inlay trade mark or badge in end cap (01) the left hand external groove, it is CR2032 that its reverse side is promptly installed garden shape battery (10) model, peeling by its lower end small gap is the interchangeable battery.Cover plate (02) has softens rubber (03) in the fish eyes aperture, so that touch just channel selection automatically of tune button (05).Also cover thin film (04) on cover plate (02), formed a kind of touch easily tune button, lateral pin (06) utilizes its central indentation (with reference to figure 2) to promote mains switch (07), so that the open and close power supply.Referring again to Fig. 1 has one and half garden connected in stars at garden arc shell (12) periphery, to place antenna (13), when this antenna draws back, because being out of shape, it has just caused two hooks up and down, catch on two in auricle, the centre is placed in the duct with earplug again, so make it difficult drop-off.The model that receives special module is CC-8A, and equal electrical ties of parts is in printed circuit board (PCB) (14) in addition for these, and loud speaker (08) encases plug with earplug (09) and listens in earhole.With reference to Fig. 3, receive special module application circuit figure, its 1 pin connects antenna (13), high-frequency signal after receive here, through inner frequency changer circuit after filtering is amplified again, from 5 pin output audio signals to loud speaker (08) playback.2 pin connect tune button (05), constantly make the variable capacitance diode charging of inside modules when pressing, and just constantly change frequency-selecting, are automatically locked at again on this channel when choosing a radio station.3 pin are positive sources, 6 pin ground connection, the external inductance of 8 pin short circuit pin 3-4 pin.
Claims (5)
1. ear-hang ear type receiver, by shell, antenna, reception special module, battery, mains switch, tune button, loud speaker, and printed circuit board (PCB) is formed, it is characterized in that: all components and parts are gathered in one, placed antenna again in the groove of garden arc shell, mains switch is installed at the housing middle part, and the tune button of automatic channel selection has been arranged in the lower end.
2. receiver according to claim 1, its antenna add plastic sheath by the deformable metal material and constitute and insert printed circuit board (PCB) again.
3. receiver according to claim 1 has adopted special-purpose receiver module.
4. receiver according to claim 1, its mains switch is connected by hidden lateral pin and is exposed to the side slightly.
5. receiver according to claim 1, its tune button are to cover thin film by the cover plate of case surface, add that in the aperture soft rubber is formed again.
