DESCRIPTION:
BRIEF SUMMARY
The present invention relates in general to apparatus for reducing the sound level of a microcomputer.
The term "microcomputer" is used below essentially to keep the text concise, but it must be understood that the term "microcomputer" covers any machine of the computer, calculator, workstation, specialized or game machine, or other type, providing the machine includes at least one microprocessor or at least one microprocessor and a rotating disk mass memory.
BACKGROUND OF THE INVENTION
The sound level of a modern microcomputer stems essentially from rotation of the microcomputer's hard disk and from rotation of the microcomputer's fan.
So long as microcomputers were machines used mainly by people acting as specialists or as technicians, such people considered their microcomputers as "professional" or "industrial" machines and it was not of prime importance to them that their machines be very quiet. However, modern microcomputers are becoming more and more commonplace appliances which may be present in a wide variety of locations, close to people whose professional preoccupations or leisure are not necessarily directly associated with continuous use of the microcomputer situated nearby. In practice, this means that there exist many situations in which a person is close to a modern microcomputer which is running, and the person is consciously or unconsciously subjected to the sound level of the microcomputer. The sound level of a modern microcomputer is relatively low, but because of the widespread use of microcomputers, there now exist many situations in which a person spends relatively long periods of time in premises where no object or appliance other than the microcomputer is generating a significant level of sound. Under such circumstances, the microcomputer is the only appliance generating significant noise and consequently that constitutes a nuisance that is becoming non-negligible.
Modern microcomputers, and more particularly most non-portable microcomputers, constitute an installed base of machines that has become relatively large. Even if it is assumed that these non-portable modern microcomputers, practically all of which generate a non-negligible level of sound, are machines of relatively short lifetime, that lifetime is nevertheless several years, and may be more than ten years. Consequently, it can be assumed that in spite of probable changes to non-portable microcomputers likely to lead to improvements that make future non-portable microcomputers quieter, the present installed base of modern non-portable microcomputers is large enough in itself to constitute a demand for apparatus that can easily be added to an existing non-portable microcomputer in order to make the microcomputer quieter.
The design of future microcomputers should include improvements designed to reduce the noise of the machine. A device of the present invention designed to reduce the sound level of a microcomputer is also suitable for inclusion in such future microcomputers, either when the machine is manufactured, or after it has been sold to an end user.
Technical solutions have already been proposed, in particular for modern portable microcomputers, that keep electrical energy consumption down as far as possible. For example, it is known that a system can be integrated in a portable microcomputer for stopping the rotary drive of a hard disk whenever the microcomputer is on standby while nevertheless being switched on. Until now, such systems have been intended mainly to provide electrical energy savings, and that is why such systems have been used solely for portable microcomputers that are battery powered, but it is indisputable that such systems have also served to reduce the sound level of a microcomputer whenever the microcomputer is on standby and its hard disk is no longer revolving. However, all of the technical solutions that have been adopted for such a system included in a portable microcomputer have been technical solutions requiring a hard disk motor drive control circuit to be integrated within one of the
