BRIEF DESCRIPTION OF THE DRAWINGS
The above, as well as other advantages of the present invention, will 5 become readily a~parent to those skilled in the art from the following detailed description of a prefe~led embodiment when considered in the light of the accompanying drawings in which:
Fig. 1 is a block schematic diagram of an auxiliary doorbell apparatus in accordance with the present invention;
Fig. 2 is block schematic diagram of the sensing unit shown in the Fig.

Fig. 3 is a block schematic diagram of the remote unit shown in the Fig.

DESCRIPTION OF THE PREFERRED EMBODIMENT
There is shown in the Fig. 1 a block schematic diagram of an auxiliary doorbell appal~tus in accordance with the present invention. An existing hardwired doorbell system includes a doorbell chime 10 which is typically 20 mounted on a wall in a house or a building and is electrically coupled to thebuilding electrical supply (not shown). Upon activation, the doorbell chime 10 emits a sound at one or more known frequencies which sound travels through the house or building as a source acoustic frequency wave 11. The chime 10 typically is connected in a circuit with a transformer and a push button switch 25 operated by a person seeking ~lmitt~nce to the house or building. When the doorbell switch is closed, an electrical current passes through the transformer primary winding and induces another electrical current in the transformer secondary winding to power the chime causing the emission of the source acoustic frequency wave 11. Typically, the chime 10 is located near the door at 30 which the push button switch is mounted.
Often, it is desirable to have additional locations for a chime since the acoustic wave 11 dimini~hes in volume as it travels from the immediate area of 2~ ~9 1 ~ 3 -the chime and often cannot be heard in other rooms or areas outside of the building, such as the backyard of a residence or a garage. According to the present invention, an apparatus 12 for sensing the acoustic waves 11 and generating a doorbell chime sound at a remote location includes a sensing unit 13 and a remote unit 14. The sensing unit 13 is mounted in the general area of the doorbell chime 10 and is responsive to the source acoustic frequency wave 11 for generating a radio frequency wave 15. The remote unit 14 is mounted at any convenient location where it is desired to hear the sound made by the doorbell chime 10. The remote unit 14 is responsive to the radio frequency wave lS for generating an auxiliary acoustic frequency wave 16 which can produce the same sound as the source acoustic frequency wave 11 or, a different sound.
There is shown in the Fig. 2 a schematic block diagram of the sensing unit 13. The sensing unit 13 includes an acoustic transducer 20 which is lS responsive to the acoustic wave 11 for generating an output signal on a tr~n~ducel signal line 21. The acoustic transducer 20 can be any suitable type of tr~n~ducer such as a mini~tllre microphone. The line 21 is connected to an input of a signal processing circuit 22. The output signal from the tr~n~ducer 20 is received by the signal processing circuit 22 which is tuned to respond to thesource acoustic frequency wave 11. Since the tr~n~ducer 20 may also respond to a range of sound frequencies including the source acoustic frequency wave 11, the signal proces~ing circuit 22 tunes the sensing unit 13 to respond only to the predetermined ~i~n~hlre of the source acoustic frequency wave 11 generated by the activated doorbell chime 10. The predetermined sign~ture can include any one or more characteristics of the wave 11 such as a frequency range, amplitude and duration. The signal proces~ing circuit 22 responds to the source acoustic frequency wave 11 by generating an activation signal at an output connected to a transmitter activation signal line 23. The line 23 also is connected to an input of a radio frequency transmitter 24. The transmitter 24 responds to the activation signal on the line 23 to generate a radio frequency output signal to a ~lrst antenna 25 connected to an output of the tr~n~mittçr. The radio frequency output signal causes the first antenna 25 to radiate the radio frequency wave 15.
While the sensing unit 13 has been described in terms of sensing the source wave 11 as an acoustic frequency wave, any physical operation of the 5 doorbell chime 10 during activation that can be sensed without an electrical connection to the doorbell chime circuit can be used to generate a doorbell chime sound at a remote location. For example, the source wave 11 can be an electric, magnetic or electromagnetic wave generated by current flowing in the doorbell chime circuit during activation and the transducer 20 can be of the type 10 which responds to electric, magnetic or electromagnetic fields respectively.
Also, the source wave 11 can be a light beam and the transducer 20 can be of the photoelectric type which has a light source and detects the reflection or blocking of the light beam generated by a moving part of the doorbell chime 10 during activation. Furthermore, the source wave 11 can be a mechanical 15 vibration generated in a part of the doorbell chime 10 during activation and the tr~n~ducer 20 can be of the type which responds to mechanical waves.
There is shown in the Fig. 3 a schematic block diagram of the remote unit 14. The radio frequency wave 15 is received by a second antenna 30 connected to an input of a radio frequency receiver 31. The radio frequency 20 receiver 31 is responsive only to radio waves having the same frequency as the radio frequency wave 15 for generating a generator activation signal at an output connected to a generator activation signal line 32. The line 32 also is connected to an input of an acoustic generator 33 which responds to the activation signal by generating the auxiliary acoustic frequency wave 16. The acoustic generator 25 33 can be any suitable device such as a second doorbell chime or a speaker.
In some cases, a doorbell chime emits another acoustic frequency wave, such as when a second push button is located at another door. Thus, the doorbell chime emits two different recognizable sounds to alert the listener to which push button is being ~-t~l~tecl and, thus, at which door the visitor is 30 located. As shown in the Fig. 4, a doorbell chime 40 emits a first source acoustic frequency wave 41. An apparatus 42 for sensing the first source acoustic frequency wave 41 and generating a doorbell chime sound at a remote 2i9~ 13 location includes a sensing unit 43 and a remote unit 44. The sensing unit 43 ismounted in the general area of the doorbell chime 40 and is responsive to the first source acoustic frequency wave 41 for generating a first radio frequency wave 45. The remote unit 44 is mounted at any convenient location where it is S desired to hear the sound made by the doorbell chime 40. The remote unit 44 isresponsive to the first radio frequency wave 45 for generating a first auxiliaryacoustic frequency wave 46 which can produce the same sound as the source acoustic frequency wave 41 or, a different sound. Thus, the sensing unit 43 and the remote unit 44 function in the same manner as the sensing unit 13 and the 10 remote unit 14 shown in the Fig. 1.
However, the doorbell chime 40 also emits a another or second source acoustic frequency wave 47 having a different frequency than the first source acoustic frequency wave 41. The sensing unit 43 is responsive to the another source acoustic frequency wave 47 for generating another or second radio 15 frequency wave 48. The remote unit 44 is responsive to the another radio frequency wave 48 for generating another or second auxiliary acoustic frequency wave 49 having a distinguishably different sound from the first auxiliary acoustic frequency wave 46. In this case, a signal processing circuit similar to the signal processing circuit n shown in the Fig. 2 is tuned to detect the two different 20 acoustic frequencies and col-c;s~lldingly generates two different tr~n~mitt.qr activation signals. The radio frequency tr~n~mitt~r responds to the two different activation signals for generating the two different radio frequency waves 45 and48. This can be done by generating the radio frequency waves 45 and 48 as different frequency carrier signals or by mod~ ting a single frequency carrier 25 signal with different modulation signals as is well known in the art. The radio frequency receiver is responsive to the radio frequency waves 45 and 48 for generating two different generator activation signals and the acoustic generator is responsive to the two different activation signals for generating the two different auxiliary acoustic frequency waves 46 and 49. In a similar fashion, more than 30 two source acoustic frequency waves can be detected and remotely sounded.
In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to l~present its prerel-ed 21 9q 1 1 3 embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.

The remote unit 14 is responsive to the radio frequency wave lS for generating an auxiliary acoustic frequency wave 16 which can produce the same sound as the source acoustic frequency wave 11 or, a different sound.
There is shown in the Fig. 2 a schematic block diagram of the sensing unit 13. The sensing unit 13 includes an acoustic transducer 20 which is lS responsive to the acoustic wave 11 for generating an output signal on a tr~n~ducel signal line 21.
