Abstract
A gravity switch 30 is set inside a telephone handset 20 so that when the handset is laid down a music-generating integrated circuit 24 is connected to a speaker 25, or microphone 22, enabling a user of the telephone to hear the music. <IMAGE>
Description
SPECIFICATION
The installation of automatique telephone music This invention relates to an installation for produc- ing music in a telephone system.
In orderto produce music in a telephone system it is common for an operator to press a retain key to actuate an integrated circuitfor sending music to the telephone system while a caller is waiting. However, the problem with such an arrangement is that the cost is high, and the necessity to employ a retain button to produce the music is an extra operation required by the operator which increases the overall workload of the operator.
Alternatively as described in Japanese Utility Model
No. 58-11085 a box is positioned adjacentthe receiver and when a handset is positioned on the box, music is produced from the box to be received by the handset.
The disadvantage of such an arrangement is the need to buy and possess an extra unit for producing music.
The present invention was conceived in an effort two overcome the above disadvantages, and provides an installation for producing music in a telephone system comprising an inertia switch mounted in a telephone handset which inertia switch respondsto a predetermined position of the handsetfor switching on an electrical circuit including an integrated circuit chip for producing musical signals, and a loudspeaker for producing musical sound positioned so that a user of the handset can hearthe music.
The invention will now be further described, by way of example, with referencetothe drawings, in which:
Fig. 1 is the sectional view ofthetelephone handset which can indicate the position ofthe invention;
Fig. 2 is the circuit diagram inside the handset;
Fig. 3 is the sectional view that howthe momentum switch runs; 3a is in open condition and 3b is in close condition; Fig. 4 is another sectional viewthat howthe momentum switch runs; 4a is in open condition and 4b is in close condition;
Fig. 5 is the third sectional view that how the momentum switch runs; and
Fig. 6 isthe circuit of this invention to show that the signal of music IC is inputted directly to transmitter.
As shown in Fig. 1 and 2, this invention is an installation of automatictelephone music.The body 10 can still keep its original installations after setting of this invention inside the telephone, for example, the hook switch 11, dialler 12, bell 13, receiver 21, transmitter 22 and speech circuit etc.
Inside the handset 20, on the space 231 inside the holding area 23, a momentum swich 30 is set and is connected to an IC set inside, for example, a music IC 24. Onthe output area of music IC24, a speaker is set, e.g. the PIEZO 25 or other efficient subjects for sending music. The music sensing direction of the PIEZO 25 shou W. betQsval d titlìei,wtarea oi elith-.e abo said' transmitter. If possible, the vocal direction of the PIEZO 25 should be close to the input area of the transmitter 22, the above said music IC needs only a little amount of power and can be obtained directly from the original circuit.
The construction ofthe momentum switch 30, as shown in Fig.3through 5, is a room made of electricity insulated material. Inside the room, there are two electricity inducting boards 32 and 33, the said boards 32 and 33 arealways in open condition.
There is agood electricity inductor such as a free solid ball 34 or liquid mercury 35 (as shown in Fig,4) in the space 31 inside the momentum switch 30. When necessary, it can inductthe electricity inducting boards 32 and 33.As shown in Fig.3a or 4a, when the momentum switch is in elect, the above inductors can induct electricity. Butthe momentum switch is turn 90 degree (when the handset is laid down flatly on a surface area) the ball drops and the electricity inducting boards 32 and 33 close and electricity passesthroughthem (as shown in Fig. 3b and 4b); so that music comes out through PIEZO 25from music IC 24.The Fig. 3 and 4 show the induction of electricity directly when the momentum bodies are changing position. In Fig. 5, the momentum ball 34 presses a flexible electricity inducting board 36 to touch another electricity inducting board 32 and thus the power is on.
In general,the characteristic of the momentum switch 30 is to apply the position changing of its inner solid or liquid materials to reach the function that the system can induct or insulate electricity directly or indirectly.
Fix the above said momentum switch 30 to the space 231 of the holding area 23 of the telephone handset 20 such that the musical circuit ofthis design is stopped as electricity disconnected when the speaker hoidsthe handset 20 in elect position and talks. But when we wantto hang in the call for a while, we can putthe handset 20 horizontally on the table and the momentum switch 30 is automatically in power, that makes the musical circuit send music to the transmitter 22 through PIEZO 25.
The above said device isa designthatPIEZO 2S emits sound wave toward transmitter 22, then the transmitter22 converts the sound wave into the signal of teiephone circuit. In addition to this indirect way, there is a simple and move direct way to let transmitter 22 produce signal. As demonstrated in the circuit of
Fig. 6, this invention usefour diodes D1, D2, D3. and D4, which are installed toward a fixed direction, to form a bridge rectifier circuit to provide powerformusic IC 24. The output signal ofthe music IC 24 is controlled by momentum switch 30 whether ittransmits the signal to transmitter 22 or not.The previously mentioned device which indirectly let transmitter 22 emits signal is difficu It to control the plarity of the circuit. Besides that,the transmitter22 may be shielded by PIEZO 25 so that the sound volume of speaking will be affected with some extent. However, the direct signal transmission way described herein can improve the above defects. In Fig. 6, momentum switch 30 is in normal open. If the design isin normal contact, it also can have an equivalentfunction, onlythe circuit device needsto make some modification, which is still in the scopeofthis invention.
As mentioned previously, this invention is cheap in costandwecan set it inside the superfluous space of the handset2O, and the telephone music can auto
matically come out. One need not set or press any
button, it is suitablefor any general types oftele- phones and the outlook ofthe telephone remains the same no matter when the musical circuit is in power or not. Any types of the above mentioned momentum switch 30 which are in the same theory should be counted as the same invention.
