Abstract

Sound radiator has an areally distributed array of plural acoustic transducers having individual drive means. A large number of transducers can be used and can be of any type. Drive signals produce phase-different sound radiations from the transducers in distributions over the area of the array having desired diffuse or particularly voiced nature. Drive signal producing means involves phase-shifting higher acoustic frequency content, and is further operative for in-phase action of at least some of the transducers in sub-area (s) of the array for lower frequency content.

A7 A7: .ο ':; ::' 部 中 定 # 准 局 π.τ. ^ Yu Cooperative Indy I ........ — -B 7 V. Description of the Invention () I ^-Technical Field Faming 1 refers to sound devices, especially devices that generate and emit sound in response to electronic signals from appropriate electronic sound signal processing devices; and specifically proposes new speaker types. BACKGROUND OF THE INVENTION Traditional speakers rely on the action of a piston to interactively drive a diaphragm using electromagnetic devices to impart sound to the surrounding air, typically a cone acting on the air. This traditional speaker is characterized by the usually complicated supply of box-type attachments for absorbing at least partially the sound components that are associated with the sound components that are intended to be directed forward; at relatively high regenerative sounds, it is more effective to listen to a narrower directional angle. The direction of the front sound is adjusted; and the attenuation of the sound intensity generated within this directional angle is a powerful loudspeaker that approaches the sound intensity from a substantial point sound source with a square law method at a distance. Multi-unit cone loudspeakers produce low, medium and high sound frequency bands with different cone sizes, which in turn need to cross over to supply signals to the unit. Recently, we have developed a completely new type of sound device including a speaker, especially the sound action and the sound diffusion, see PCT Application No. GB 96/02145. The sound action of the speaker is related to the specially-designed position to properly construct and configure the panel excitation to cause the basic clock # piston method to vibrate the surface to the bending wave of the air. The sound radiation produced may actually come from the entire panel surface and produce a highly diffused effect over a very wide range of angles. Since the previous approach, the previous close-up b. 丄 g 'and long-term omnidirectional features have been removed, and For individual panel units exceeding a very wide frequency band, flat and flat. The geometry and stiffness characteristics of the panel are -4 according to the specific position f of the exciter device.-This paper is a thick scale suitable for Sichuan China Weijia standard net ((, NS)) Λ4 specification (210X297 mm) 11-: 1!-I. ......--I Jl ·-士 fe-I -1 .......: -.-.

Description of the invention (2) — It helps to achieve the spread of the resonance frequency mode of the surface vibration effect, as it promotes the wide-area, directional diffuse sound emission. The advantages of the previous piston speakers are good and they often have the disadvantage of inconvenient listening position (or the particularly famous stereo reproduction) inevitably continue to the narrow angle of orientation ', and often uncomfortably extremely high loudness inevitably continue to the point Source square-law attenuation effect. In addition, the specified mid, high frequency bands, and subsequent crossover networks of the previous preferred embodiments can give repeated complex rearward absorption with a box-shaped five-screen sound element. — Starting. The present invention is based on the sound optimization of a successful distributed mode panel device. The point function appeared in two considerations. The advantages of the sound emitted by the present invention have been shown in the integration ratio of the emitted sound in the same space. At the same time, the superiority is related to the plurality of flat speakers in the same space (and wavelength-dependent interference). This spatial Fan Garden reflection effects, such as walls and / or ceilings and / or floors (and vertical wave interference), and low-sense auditory places and / or insertion effects, so better balance and / or mutual non-interference and flatness The plural channels are like the center, front stereo and surround back sound units such as home theaters, or more commonly used in public addresses. The first and most natural concern and attention is the focus on whatever may be suitable for maintaining a flat plate in flexural waves and / or in The plate's excited resonance mode of vibration propagates well. However, many of the purposes and spirits here—the fundamentally different basis—have been adopted using fundamental principles for evaluation. Explicitly the basic contribution of diffuse-type sound emission as described above; And how to usefully achieve different sound emission effects beneficially, whether or not effectively Group of self-distributed mode bending wave action speakers.

Description of the invention (3) The results are considered to represent a more completely different approach. 丨 Summary of invention— This approach emerges from the obvious characteristics of the sound of a typical piston-type cone speaker, which is effectively phase coherent, and from the characteristics of the non-piston-type eight-cloth mode flat-panel speaker sounds that depend on pending wave action. According to a type of the present invention, a sound transmitter includes a plurality of area distribution arrays of sound converter units with individual excitation drivers or excitation devices, and the driving signals cause the sound emission of different individual phases, which is directly related to the driver. The input phase of the signal is suitable for the integration of the output of the individual unit as if it produces useful scattering from the array area and / or emits sound in the desired direction, rather than the previous narrow beam angle with increased frequency. The phase 疋 is suitably disordered or incoherent when facing the converter cell array from as low as 20 or less to as high as 750 or more. We believe that the well-known electrostatic speakers mentioned at this point are useful. Compared to conical speakers, the effective sound emission area is formed by pneumatic sub-areas that are carefully and orderly phase-shifted, so The loudspeaker Chen now notices the point source directivity of the coherence and sound emission, so it is different from the plan. Returning to the type of invention described above, the desired phase discontinuity of the complex unit that produces the diffused sensation that proves the directivity of conventional speakers and the overall emitted sound close to loudness is not essentially a similar type that occurs in the above-mentioned distributed mode bending wave plate. Indeed, the similar type of research is based on this; the area distribution angle of the plate resonance mode may most naturally include a matching unit distribution and the operating frequency relationship of the converter unit.

The better application method can still allow the Baoqubo action plate to be bound to avoid the flatness of the surface distribution of its action resonance mode, which is the same as the geometry and hard requirements of the plate. Independence achieves farther propagation. Better diffused emission sounds with different phases at least in relation to individual converter units of an overall array. Proper distribution of sounds is more messy than conventional, coherent film-type traditional speakers, including the aforementioned electrostatic speakers. According to the same understanding, when a valid pseudo-random number generator and / or random number list intends to exclude high regularity and / or aggregation, it is appropriate The phase distribution of can be considered to be randomized. When the phases are different from each other, individual and / or cumulative cancellation effects are easily avoided, for example, it is easy to be reached by this limit if it is not an entire i 80.

However, 'fortunately, the possibilities shown by me, any particular distribution that is considered to satisfy the special different phase of any particular array of converter units, and will usually be simplified and can be completed or seen as fixed or The rules of application concern. Moreover, the number of different phases does not need to be the same as the number of converter units, that is, some may be the same, as long as the number and distribution of different phases produce an acceptable perceptually diffused overall sound, a more similar to that of more units The situation is concerned in the array. Today's development work indicates that this specific embodiment can be achieved with continuous bending. Please read the note on the back-then I. Binding on this page.

Description of the invention (5) Curve wave action Flat panel speaker Compared with the audio operation fan garden, in particular, it can achieve the frequency of the transmitted sound and feel the smooth sound effect of the diffuse sound. In addition, the lower sound class can also be easily processed, although there are some difficulties. Therefore, under the restrictions, the array is actually concerned about the size of the array The lowest frequency can be effectively similar to that of the previous one; tongue-type speakers are simplified by correspondingly driving signals applied to all converter units on in-phase bias voltage, that is, substantially continuous. Of course, the resulting directivity is The fact that a large number of low-frequency cone-type subwoofers are well-accepted in the past is no longer a problem. The low-frequency in-phase driving mode is applicable to all converter units of the array, that is, only the units to the sub-area of the array. The central subarea can be retracted, typically step 1¾, and handled well with a frequency rise through a low-range random different phase mode that is lower than the above operation. The phase processing of the drive signals to the individual sound converter units of the array represents a very varied and convenient mechanism in the organization's desire to emit sound effects, and constitutes another type of the present invention that does not need to be restricted to combine the essential coherent and different operation of different frequency bands Consecutively, there is no converter unit that cares about the sub-areas adjacent to the overall array area, that is, it may be found beneficial in other patterns, in circles or corners. The drive signal amplitude processing to individual sound transducer units of the array can have beneficial effects. It has been established that the overall sound emitted by the array senses, and the distribution of the different amplitude regions of the drive signal of the transducer unit constitutes another type of the present invention. , Regardless of whether the accompanying phase distribution is preferable. Returning to the operation of the array sound converter unit in a normal phase method, it is also feasible to simulate the replacement of all or part of the above-mentioned in-phase mode, especially the expansion of _________ _ 8-paper-like financial assets _ house system (A7 B7 five inventions Explanation (6 Any desired direction of string vibration or extended film vibration, for example, 'delayed extension: late wires can be used to feedback individual units, and / or this bend === moving single-second recursive all-pass filtering The unit can be used for each unit, and different feasible separation frequencies can be used to switch between each unit mode. Of course, this other operating mode

It may be additionally useful, and the effectiveness of two or more substantially orderly and / or L-ordered phase and / or amplitude modes of operation constitutes another type of the invention. Regarding the actual structure, it is better for individual converter unit arrays to have a common sheet or flat board carrier device. Regardless of softness or rigid nature, and the appearance of the surface does not require a market plane, it can be bent in one or more directions. In order to help For the manufacture of small converter unit arrays, a better carrier device can further assist the desired application of the individual drive signals of the converter unit, conveniently as a substrate with a related conductor pattern, after a good method of establishing a printed circuit board. Indeed, the carrier device can also be usefully used in the area drive signal circuit addition, such as a module semiconductor integrated circuit type. Of course, the further impact of this vehicle device may be an effective way to achieve an ideal overall sound emission surface that results in the sound output exhibiting a substantially random vibration with low or minimal in-phase content desired. Sound emission will have the possibility of this phase discontinuity. This I & peripheral feels even lower (or wider) frequency-independent directivity than traditional piston speakers, a function leading to a more even frequency distribution of sound power. Useful profitability then clearly appears to match what actually occurs in discontinuous flat panel speakers, including the use of highly efficient conical piston-type diaphragm units that are currently particularly small.
