Description of the invention (1) Field of the invention: The present invention relates to a device after compensating for sound effects, in particular, a device that allows a headset-like or headphone-like device to simulate a virtual speaker behind. BACKGROUND OF THE INVENTION: With the rapid development of the electronics industry, it is common to play sound effects with advanced acousto-optic effects on computers. Therefore, the demand for video and audio performance has become more and more urgent ^ 〇mmit ^ MM Μ 41% M ^ f S ^ 5 4- Λ Response frequency: In the field of sound effects, multi-channel (mult i- Channel sound has gradually replaced stereo sound and mono sound. In order to provide a home theater with a more realistic or engulfing listening experience, many technologies have developed the form of multi-channel sound effects. Each audio channel of a multi-channel signal is sent to one of the many speakers distributed throughout the home theater to provide a thrilling sound, and the sound in it triggers all the ring-field effects. As the market for home entertainment systems expands, other multi-channel systems are likely to become available systems for home consumers. Humans can distinguish sound to the left or right based on the difference in arrival time and sound level recognized by each ear.

Description of the invention (2) The head-related conversion functions (h e a d r e 1 a t e d tfansfer functions; HRTFs) use fixed speaker positions to simulate position and virtual stereo sound. The shape of the human head, body, and hearing system affect how the human brain perceives where the sound originates. HRTF is a characteristic description of the human head, body, and auditory system. Therefore, the above HRTF is affected by the shape and size of the head, the shape and size of the pinnae, and the characteristics of the ear cana. This is a typical function of related orientation. HRT1 (response), frequency filtering (f i! Teri ng) and the inherent delay and response in the human head. By adjusting the frequency and delay of the sound signal of the HRTF, the stereo: the sound can be simulated from a fixed speaker position to the virtual orientation of the simulation. U.S. Patent No. 5,72 9,6 1 2 is entitled, “Apparatus and Method for Measuring fTF”, which was filed on August 5, 1949. Application f 1 1 ed). The above-mentioned conventional technology discloses an accurate drive The method of sound conversion function (such as HRTF). I ^ RTF can be calculated individually by measuring the characteristics of the head, ears and body. The above-mentioned individual measurements are converted to a conversion function using an appropriate processing device The purpose is to adjust the characteristics of the sound signal rotation of individual machines and simulate their positional three-dimensional because HRTF is based on the sound heard by the human ear to simulate the sound effect model of the three degree space. And the parameters of the stereo sound effect corresponding to each area in the space are determined by its distance, orientation (aZlm = th), and elevation (elevation), and the above-mentioned just when the listener feels that the sound is at the most In a real atmosphere. HRTF uses an artificial head or ffl i crophones; within the human ear. Each sound source must be measured in the frequency range of 20Hz ~ 20kHz. The result becomes the preliminary HRTF database. The above-mentioned preliminary HRTF database generates the parameters required by the DSp chandelier through mathematical operations. As long as it is through the left and right digital filters The processed single-wave sound can imitate the true 3D stereo sound through the earphone device. The three-dimensional space sound device applied to the personal computer includes an analog ring field multi-speaker with two physical speakers to transport five "Virtual speakers", (virtual speakers) to the space surrounding the listener, and make the home theater sound. However, '5.1CH DVD or 4CH 3D games are virtual speakers using HRTF to generate the rear channel, To replace some of the difficulties encountered in providing physical speakers for DVDs and 3D games. Generally speaking, the wavelength of the bass is larger than that of the human head, so the previous technology cannot provide direct bass information from the structure of the headphone device. The subwoofer of the subwoofer speaker can provide sufficient signals for all channels. Do not
