Embodiment
But describe in further detail below in conjunction with accompanying drawing and embodiment telephone set to the utility model recording playback individual character the tinkle of bells:
Embodiment one, and with reference to Fig. 2, Fig. 3, hand-free circuit is a ground connection in parallel with the handle speaking circuit, and HS is a switch hook, and ON is at hook state.
During on-hook, telephone wire 48V voltage makes M point voltage (U behind polarity orientation circuit D1-D4
M) be about 46.4V, voltage U
MCharge to C1 through D5, D8 and R1, C1 voltage is charged to (U
M-U
D5-U
D8), the voltage U of capacitor C1
C1＜U
D9, Q2 ends, and Q3, Q4 also end.Q3, Q4 have only the electric current of several uA when ending, do not consume substantially.Simultaneously because of U
M＜(U
D5+ U
D7), so D7 ends, Q5 also ends.
During incoming call, ringing voltage after polarity orientation circuit D1-D4 rectification with the addition of M point primary voltage, make the pulsating dc voltage of M point voltage appearance＞46.4V, pulsating voltage U
MThrough D5, D8 and R1 C1 voltage is further risen, the voltage U after the rising
C1Make the D9 reverse breakdown, Q2 is saturated, and the Q2 current collection is low level very, and low level makes Q3 and Q4 all saturated, and power supply E gives ISD recording and playing circuit, the power supply of hands-free power amplifier through Q3, Q4; While pulsating voltage U
MMake D5, D7 reverse breakdown, make Q5 the saturated of synchronism occur through R2 and end, produce the trailing edge trigger impulse, make ISD begin playback.The audio signal of ISD output is delivered to the audio input end of hands-free power amplifier through switch SW 2, capacitor C12, and ring signal is delivered to loud speaker SP1 and sounded after hands-free power amplifier amplifies.The ISD playback is triggered by the trigger impulse of Q2 again after finishing again, and playback starts anew.D10 can prevent that capacitor is breakdown in the process of C1 charging.
Off-hook, no matter be this machine off-hook, or other telephone set off-hook in parallel with this machine, the voltage of telephone line all can drop to about 7-15V, at this moment condenser voltage U
C1Discharge U rapidly through R3, D6
C1Moment reduces, and D9 ends, and Q2, Q3 and Q4 end, and the ISD circuit is de-energized and stops playback.
Telephone set conversation back on-hook, capacitor C1 is charged to (U again
M-U
D5-U
D8).
Bell signal is to send 1S, stops 4S, and when sending a telegram here in the withholding period of bell signal, the voltage of C1 can be about 46.4V through R3, D6 discharge.As want to improve C1 at the voltage of the withholding period of bell signal, and R3, D6 branch road can be gone here and there a voltage stabilizing didoe again, and this moment, C1 voltage should be " 46.4V+ newly go here and there diode voltage stabilizing value ".
Switch SW 2 is a bell sound selector switch, and the H position is big bell sound, and the L position is the skellat sound.
Close the bell sound when switch SW 3 disconnects, can avoid the influence of bell sound to have a rest.Flicker during light-emitting diode D8 incoming call, the convenient incoming call of when closing the bell sound, observing.SW3 can be connected on a plurality of positions of circuit, can connect with the collector electrode of Q2, perhaps connects with the emitter of Q2, perhaps is serially connected in the series arm of Q2 base stage, D9, R4.
Power supply E can use battery, also available external power supply.In cordless telephone, all have external power supply, need not to increase power supply originally.
The ISD1100 record playback time is 10S, and ISD recording playback sound has multiple model, and record length does not wait from several seconds to a few minutes.
SW2 is the duplex three-position switch, and REC is the recording position, and WAIT is for waiting for current potential, and PLAY is test playback position.During recording, some A, D, E and H be ground connection, and some D ground connection makes triode Q3 saturated to the recording and playing circuit power supply, and some H ground connection makes circuit begin recording.Light-emitting diode D12 can record in normal bright prompting during recording, and recording finishes, and D12 goes out.During the test playback, some A, B, E and F ground connection, some B ground connection are powered all saturated recording and playing circuit, the hands-free power amplifier given of triode Q3, Q4, and some H ground connection makes playback circuitry begin playback.The test player function having been arranged, do not needed the effect by the recording of making a phone call just can know, also is a good toy to children simultaneously.
J is that outer signal is selected jack, when not inserting external signal line, and internal switch K closure, record the sound that the built-in miaow head of circuit MIC picks up this moment, and when outer signal, internal switch K disconnects, record the external audio frequency signal this moment, and the external audio frequency signal can come from computer, MP3 etc.
Adopt the trailing edge pulse really to send out and the true originating party formula of low level during the playback of ISD1100 chip, adopt the true originating party formula of low level during recording.Playback also has the pulse of the rising edge of employing really to send out and the true originating party formula of high level in the ISD series, and the true originating party formula of high level is adopted in recording.When adopting the chip of rising edge pulse and the true originating party formula of high level, the E of playback switch SW1 point is earth-free in the circuit, should receive the power end of recording and playback ic, capacitor C4 should be connected between the ground of REC end and recording and playback ic simultaneously, and the power end at chip should be connected a resistance with the PLAYE end simultaneously.
Embodiment two, and with reference to Fig. 4, Fig. 5, that the handle speaking circuit connects is virtual earth Vss, hands-free power amplifier be connected and virtual earth between, be the earthing mode of connecting with the handle speaking circuit, switch hook HS is at hook state when ON.
During on-hook, the charging current of giving C1 is except that process D5, D8, R1, C1, also to pass through D13, hands-free power amplifier path just arrives ground, current direction is during the incoming call playback: E positive pole → Q4 → hands-free power amplifier → Q6 → virtual earth (E negative pole), D13 is used for isolating amplifier power supply end and virtual earth, in order to avoid electric current forms short circuit through E positive pole → Q4 → virtual earth (E negative pole) during playback.The ground that Q6, R16 form is to the current path of virtual earth, Q6 is saturated during playback, if do not adopt to the current path of virtual earth, hands-free power amplifier also can be worked, but the current direction of this moment is: the voltage stabilizing didoe → virtual earth of E positive pole → Q4 → hands-free power amplifier → hands-free power amplifier (E negative pole), and the saturation voltage height of the forward conduction voltage ratio triode of diode, the real work voltage that hands-free power amplifier obtains also can descend to some extent, multiplication factor reduces, and is unfavorable for making full use of power supply.The same Fig. 2 of the remainder of circuit, Fig. 3.
Embodiment three, with reference to Fig. 6, Fig. 7, amplify the power amplifier of ring signal and are made up of audio frequency transformer T, triode Q7, resistance R 17.
The audio signal of ISD output is amplified through triode Q7, again through the transformer coupled loud speaker SP1 that arrives.The same Fig. 2 of remainder, Fig. 3, this example is applicable to all telephone sets,, particularly do not have the telephone set of hand-free function.
Embodiment four, and with reference to Fig. 8, telephone set has common the tinkle of bells and individual character bell sound function simultaneously, select by switch SW 3.When SW3 is in " individual character " position, select individual character bell sound mode; When SW3 is in " general bell " position; What select is common ring mode; When SW3 be in " quiet bell " position, the tinkle of bells is closed.The shared loud speaker SP1 of common ringing circuit and individual character ringing circuit.
