Description of the invention (1 Technical scope The present invention relates to a device combining a vibration sound device with other sensors and extra functions. Background Art Animal Wave or Distributed Mode Speaker (DML) Expressly stated in the international application WO97 / 09842 and other documents. Such speakers can be used in applications where the speaker has additional functions. For example, international applications \ ^ 〇97 / 09843, ^ 〇97 / 09 85 3 and \ ¥ 〇〇〇 1/31971 describes the use of such panels as ceiling tiles in projection screens and keyboards. In addition, the application of DML technology has been expanded to incorporate tactile-sensitive opaque and transparent speaker panels. For example, the international application is disclosed as 〇〇〇 / 54548 Incorporates a speaker electronic device with a curved wave panel member, which has a user-accessible surface 'an electro-acoustic vibration exciter located on the panel member to introduce bending wave energy to the panel member' in response to electrons applied thereto Signal, and the user can access the surface or related to at least one tactile sensitive surface in order to respond to user contact. International application WO01 / 48684 has described a contact sensitive Device, which includes a transparent touch sensitive plate mounted in front of the display device. One of the purposes of this invention is to extend the use of sound radiation surfaces beyond sensitive devices' and include other detection functions. This principle can also be applied to curved wave speakers (ie DML ) And piston booster radiator. SUMMARY OF THE INVENTION In accordance with the present invention, 'provide a device including a curved wave panel speaker having a surface curved wave panel, and an electric sound converter connected to the curved wave panel' to be included in the panel. Generate bending wave to produce a sound output, one lose -4-This paper size is suitable for financial and household materials (CNS) A ^: (2l () x Norwegian public director) 5. Description of the invention (input device constitutes one of the input surface) ^, And a mechanism to provide powerful feedback to this device, the speaker and the powerful feedback facility are combined on the same surface. The converter can stimulate the panel to play sounds of different volumes. Sound output ^ Μ, ㈣ Output device adjustment, depending on application II =: device: speaker can be used in reference mode, such as hands-free, one or two, or used in telephone mode to stay on the user's ear. Panel 2 force: such as ringer speaker 'And / or for mobile phones, pagers, etc. H. Powerful feedback facilities are also referred to as tactile. Input devices may be tactile sensitive input devices or keyboards. Devices providing selective force feedback may be used for second converters. Type, installed on the panel that provides the pulse wave to the panel = 'pulse wave may be an instantaneous spike signal' and thus provide a button-click feeling. Or, a single-dual function converter can generate sound output and strong feedback. Or 'Passive strong feedback can be achieved by mounting the panel around a non-linear panel base' The panel base provides a button-tick feel when a part of the panel is pressed. The area of the input device can be locally heated to provide tactile sensation Turn round. Display board light and one or more of the clothes may include a visual display device related to the curved wave panel. The visual device can be a type of traditional display surface, such as a liquid crystal display (LCD) surface. At least one part of the panel is transparent, and the visual line-of-sight device can be installed behind the transparent part of the surface. Therefore, the panel serves as a transparent display window. Alternatively, the panel can be used as a display, for example, as an emissive surface coating layer containing a light emitting polymer or pigment. Therefore, the number of components in the device can be avoided without loss of diversity or functionality. This paper size applies the Chinese National Standard (CNS) A4 specification (21〇χ 297 mm) -5- 532043 5. Description of the invention (other functions can also be improved. • u panel can be used as a microphone and / or speaker. Or, a One or more microphones can be embedded in the panel. Any of the following can be embedded in the panel ', that is, a still or video camera, heating and / or cooling elements, and various different sensors, that is, chemical components, electrical appliances, first Gages, etc. σ 丄 may be included in the panel 'such as passive chromaticity polishing, that is, anti-shine $ reflective ^ layer. Or, or in addition, active chromaticity such as light chromaticity 乂 heat ^ may be provided. The panel may have surface texture Or the variable surface contour. See Guang Guiwei's stupidity and other detection functions can be integrated into the panel at the same time. Therefore, the faceplate can be called a super functional surface (HFS), because :: The assembly can provide functions The number of synergy increases. The function provided by the panel is from any one of the above functions; Ø 4S. Power Moon Dagger. For example, using a transparent, tactile sensitive panel with a strong feedback facility, the device can be used in combination. Viewing assets ^ 柃Acoustic signals (messages, radio outgoing sounds, ticking sounds) and ticking sounds simulated by fingertips. The advantage of this device is that by using a touch-sensitive panel, the unique feeling of separate keys can be eliminated. For small electronic equipment It is particularly useful, such as hand-held display and limited space for its components. In some applications (the size of communication and computing devices and the volume of each component inside it has been reduced or even intersected.) The use is therefore based on the functional surface area of each unit. = The trend makes designers have to choose the emotion of any fixed surface as the device of the present invention can reduce the required surface area to provide multiple functions. The present invention is It is considered that the combination of vibration sound and its detection characteristics and functions has led to important manufacturing benefits. The use of this device can be referred to as the Chinese paper standard (CNS) A4 standard (210 X 297 public love). '6 ^ 532043 A7
