Description of the invention (3 ) In the public room, the standing, 9 can also be transmitted by passing back to the compartment below the ceiling, and by reflecting the ceiling between the office cubicles = in the closed and open office plan, the noise Penetration is also transmitted through the ceilings, equipment and conference spaces, and ceilings suspended from above, and inversely through the ceilings, equipment and conference spaces, and the ceilings and floors below. There are two ways to reduce unwanted sounds from appearing in space. The sound decays as it passes from the source and throughout the room; it is salty, or I overwhelm it by using masking techniques. In promoting the privacy of closed offices, the ceiling system, the main character, cuts off the transmission of sound, and absorbs the sound that hits the ceiling to avoid reflecting it back into the work space. For critical human speech The absorption effect at frequencies between 500 and 4,000 Hz is expressed in terms of the proportion of sound absorbed by the ceiling material. A panel's ability to absorb sound (in closed rooms) is measured by the noise reduction factor (NRC). The noise reduction factor of 0.6 is a recommended value that supports normal speech privacy and good sound quality in a closed office. In open-plan offices, where speech penetration between compartments is the main consideration, the applicable ceiling efficiency is provided by the AC (pronunciation level) rating of the ceiling. For good speech privacy design, it is recommended that the ceiling pronunciation level is at least 170, more preferably 200 or above. Distractions from conversations and uncontrolled noise are the main factors that reduce production in the office environment. Sound masks work by including sounds in the special frequency range. Adding I--1 to the spectrum occupied by human sounds. Appropriate sound provides a masking effect. It's too fair, and I like it.

Description of the invention (6) 〇 Summary of the present invention This specification discloses a system for installing a flat panel transmitter in a suspended ceiling system. The panel transmitter consists of a rigid panel and a transducer consisting of a magnet connected to the panel, a sound coil also connected to the panel, an optimized sound absorption cover connected to the face side of the transmitter frame, and an excitation The source of the line. The working principle of the flat sound transmitter is that the exciter hung on the flat plate vibrates the flat plate to generate sound. The sound field produced by the flat-panel transmitter is not limited to the cone of sound produced by ordinary loudspeakers. The vibration of the flat plate generates complex and random wave fluctuations on the surface of the plate. In the ideal mode, the sound is emitted in a wide circle, just like a flood light radiates light to a wide area. This is different from a standard cone-shaped loudspeaker, which can be considered to produce sound rays like a piston. It emits a straight beam of light compared to a point light source. The circular distribution form of the flat panel transmitter indicates that the sound level is the same in a large audible area. Flat panel transmitters have a wide range of sound emission forms at frequencies that require sound masking. As noted, the flat panel transmitter includes a lightweight, rigid launch plate of any size, and a transducer. The transducer has a magnet to clamp the transmitting board, a voice coil component is also connected to the board, and a line connected to the excitation source. When the current passes through the sound coil, the combined result of the electromagnetic field force and the magnetic field will cause a small relative displacement or bending of the flat plate material at the mounting point. Rather than coherent piston-like motion like a cone-shaped loudspeaker, the motion of a flat plate is absolutely incoherent and includes many different complex patterns distributed over the entire surface of the transmitter. This effect has a significant effect on the emission form of the wide interpretation. The first paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 x 297 mm) 91925 (Please read the precautions on the back before filling this page) Ministry of Economic Affairs Printed by the Intellectual Property Bureau employee consumer cooperative I nnnn ϋ i-n II ϋ I nnnnn 1 ϋ ϋ n ϋ ϋ »1 ί nn nn H H ϋ 印 Printed by the Intellectual Property Bureau employee consumer cooperative of the Ministry of Economic Affairs 7 513501 7) And this technology lacks the characteristics of beam behavior. This is best achieved with a honeycomb cell-type material that is lightweight and does not rust. Honeycomb materials provide minimal loss and smooth sound pressure response at low, medium and high frequencies. In other forms of highly sound absorbing ceilings, the use of standard flat sound transmitters tends to neutralize the achievement of speech privacy in specific situations. These situations include whether the flat-panel transmitter is directly above or in-line between two connected office rafters, because sound waves are reflected from the flat-panel transmitter and enter the connected office space. The present invention provides a mounting structure with a visible surface with optimized sound absorption characteristics like a flat panel emission f. In this installation structure, the flat panel transmitter is installed in the frame of the suspended ceiling system. Qin Zaowu, and the specific sound coverage is connected to a frame that surrounds a layer of air and frost between the cover and the flat panel transmitter. unit. If the transmitting board is first connected, then Xia Xia will use laminated or coated surface treatment: If the sound: the hollow coverage is connected at an offset from the surface of the transmitter, then the transmitter board will act as a sound reflector for the sound in the room. character of. The specific coverage has a specific π-character sound and is strategically installed below the surface of the flat-panel launcher. Alumium Λ K-Fen provides effective acoustic absorption in a specific manner. The coverage and air layer are used as a sound absorber, and they can optimize the function of the sound of the flat panel transmitter. Qing said the value of the amount. The coverage also has a beautification style description. You can learn more about the present invention by reading Figure 7 of the following detailed description of the present invention.

Description of the invention (10) When diffused and stable, as indicated by the arrow. Point the amplifier directly down through the antenna board or install a general amplifier Above the ceiling, The frequency used to create the uneven sound field is accompanied by some areas that sound louder and some sound less loud. To compensate for this will require more: when high: value loudspeakers. But will expand The price of the loudspeaker's upward emission is that Aida has additional power to drive the loudspeaker to practice the degree of sound that it wants to give the listener. Alternatives to flat-panel transmitter technology to produce sound masks have been developed. Historically, attempts to make flat-panel transmitters of high quality have focused on doubling the behavior of conical microphones. These efforts have not been successful until recently. The flat-panel transmitter is now feasible because it has a wide range of sound emission frequencies for masking sound in an open workspace environment. The flat-panel transmitter, as shown in Fig. 2, includes a light-weight, rigid transmitting board 200 of any size, and a transducer. The transducer consists of a magnet 200 clamped on the transmitting board 200, a voice coil 200 connected to the transmitting board 200, and a wire 203 connected to an excitation source 204 that is not part of the transmitter system . There are at least two forms of transducers that can be used in flat products. Figure 2 shows the "bender," or "clamped," drive. When a current is passed through the sound coil 202, the electromagnetic field of the sound coil interacts with the magnetic field generated by the magnet 201, thereby causing a small relative displacement or bending of the flat plate material 200 between the sound coil 202 and the magnet 201. Different from the continuous piston-like movement of the conical microphone, the movement of the flat plate 200 is clearly discontinuous and contains many different complex patterns distributed over the entire surface of the transmitter 200. This effect is obviously the first application of the broad emission form and the lack of beam gas technology 91925 (please read the precautions on the back before filling this page)

Description of the invention (11) In the current technology, the flat panel transmitter is installed in the frame, so that it is installed in the standard anti- "T" ceiling grid. Figure 3 shows a portion of the ceiling lattice, including a main beam 600 opposite the T, a suspended suspension cable 601, and a cross T beam 602. The transmitter board frame unit 603 and the connected bridge support unit 604 and the accessory 606 are arranged in a grid unit, as shown by a dotted line 605. The accessory 606 includes a terminal block (not shown) to connect the transducer to an external drive source. Fig. 4 shows an embodiment of a C-shaped frame in which flat-panel transmitters are mounted in accommodating units of different sizes in the C-shaped frame. The flat-panel launcher 200 is supported by a C-shaped Baogu early element 212 of different sizes, with fixed boundary conditions, and is housed inside a C-shaped frame 210. The bridge supporting unit 604 is disposed above the frame 21o and intersects it. The bridge supporting unit supports a box 61o including electronic components, which is used to drive the vibration on the flat panel transmitter 200. The frame 2] has an insulation unit 214 below the bottom surface of the frame and overlaps the flange of the ceiling lattice system 600. The insulation unit 214 may be made of a flexible material such as a foamed material. The isolation unit 214 mechanically and acoustically isolates the flat-panel transmitter from the grid support unit 600, and prevents transmission of vibration from the flat-panel transmitter to the suspended ceiling system. Covering surface 236 is added as an acoustic impedance cover to the flat panel transmitter and can beautify the other parts of the ceiling. The acoustic impedance of the coverage is close to 800 MKS rayi with optimized sound absorption. The acoustic impedance of the coverage should generally be between 400 and 4000 MKS thunder ears. As shown in the figure, the containing unit 212 can vary in thickness to create different design depths from the lower surface of the flat-panel transmitter to the acoustic impedance coverage.
