Summary of the invention
According to invention, provide one to be used to be attached to the panel of a rigidity and to be fit to add at the bending wave energy on the audio frequency module that makes the output of panel energy radiation one audio frequency on the panel whereby at this.It comprises that one is suitable for being fixed to the shell of panel, on shell, be fit to for example to utilize the help of bonder to be used for shell is fastened to the pin shape device of panel, one in the enclosure motor converter, when transducer adds an electrical audio signal, be suitable for supporting this transducer to be connected to panel in the enclosure the bending wave energy is applied to the supportive device of panel and audio signal amplifying device in the enclosure.
Pin shape device can be equipped with the pad that shell is fixed to the pressure-sensitive adhesion of panel.Pin shape device can be successional or comprises the pin at a plurality of intervals.
Transducer can be piezoelectric type or magnet and coil class.Transducer can be inertia, can be installed on the shell easily in this situation, or can give ground connection on shell.Converter apparatus can be adopted bonding mode and be fixed on the panel.Therefore it can be mounted to shell through its magnetic force easily when transducer was an electrical propulsion unit, and cohesiblely for example adheringly secured to panel through a pressure-sensitive panel and through its sound coil.
Preferably the shell on panel be installed as flexiblely, so the part at the regional inside and outside shell of pressure-sensitive adhesion device can have elasticity.This mode can be reached by the pin shape device that the shell that forms the elastic flange with peripheral inward direction forms.
The audio signal amplifying device can be adopted elastic type and be installed in the shell.
Shell can be added with aperture so that will pass through shell from the audio frequency energy of panel.
Shell can be placed with several dry cells and supply power to signal amplifying apparatus.This kind battery can be that the power distribution that becomes balance on the transducer suspension body is reached in the placement of the symmetry of essence around transducer.
Description of drawings
The present invention cooperates drawing to come diagram to show with way of example, wherein:
Fig. 1 one is used for a display panel is converted to the cross-sectional view in side front of first specific embodiment of the module that produces audio frequency output, and
Fig. 2 is the side front cross-sectional view of second specific embodiment of module.
Embodiment
Module 12 shown in Figure 1, thus its for example be used for will be generally serve as that the main firm panel of making of for example buying advertising display panel 9 forms is converted to and can provides audio frequency output to strengthen the plate that shows with cardboard or similar rigid lightweight material.
Module 12 comprises a shell 6, it is one to have by the inside circular panel of the rigid plastic body that forms of the pin shape device of the elastic flange 11 of counter-rotating of a plurality of intervals periphery that has pressure-sensitive adhesion pad 5 such as one, whereby on the surface that is fixed to display panel 9 that can shell 6 is firm, and flange 11 provides the resilient suspension of shell 6 on element 9.
Shell 6 comprises magnetic combination 15 and one sound coil combination 16 with an inertia class electricity-acoustic transducer 1.Transducer is coupled to shell 6 by a resilient suspension body 2 and the sound coil combination is to borrow pressure-sensitive adhesion pad 13 firmly to be fixed to plate 9.This mode can make transducer that the bending wave energy is added to plate 9 and make it the radiation voice output.Shell elasticity or flexible installation onboard can prevent that shell from hindering the propagation of bending wave energy and assistance and preventing not needing of shell or do not have so the vibration that causes.Therefore, also can provide the function that damping or certain mass loading improve panel on the shell.
Shell 6 is with signal amplification electronic device 18, and for example one to be installed in PWA on the printed circuit board (PCB) 3 be the pulse duration amplifier and be used for battery 8 to the power amplifier power supply.Printed circuit board (PCB) 3 is installed on the flexible fixing body 4 in the enclosure.Module housing 6 is also with the audio signal storage device 19 that is connected to audio frequency amplifier electronic installation 18.The audio signal storage device can for example be a tape player or Small-sized C D player or similar device.
On shell, be formed with aperture 10 will from the acoustic energy essence of panel 9 straightway through shell give by.Device has on the printed circuit board (PCB) 3 of electronic installation 18 and is used for the similar formation aperture of identical purpose, can provide to the power connector 7 of the amplifier 13 alternative usefulness as internal cell.
Type shown in Fig. 2 shown in Fig. 1, be applied to the module 12 that display panel 9 is converted to display panel loud speaker.Module housing 6 borrows one to be arranged on and to have a self-adhesion device (not shown) that is connected on the peripheral base 17 of one one-tenth undulatory resilient suspension body between base 17 and the shell 6 and be mounted on the display panel 9 in this specific embodiment.Battery 8 becomes impartial force distribution along 1 one-tenth impartial placement of transducer to assist the transducer suspension body in the enclosure.How easily module also closes a fixed-site in office to the external sensor 20 of panel 9, for example a PIR is passive infrared motion sensing device, and the sensor of a photocell or a sensing microphone form is so that make combination import response to one from the approaching or sound by person's form.
Module selectively be positioned on the display panel this place add the bending wave energy and be used for that useful being coupled to can obtain and required pattern on distribution and exercisable frequency range, for example the applicant is stated in International Application No. WO 97/09842.
In the plate electronics is provided with, can in module, provide and be used for storing, receive, choose and the memory body and the signal processor of decoding audio data.
It can be 0.1 watt to 10 watts in output for example that audio frequency electric power to the amplifier of exciter is provided, and for example is higher than at high power under 1 watt the situation and can adopts numeral or switching technique, can reduce the needs that adopt large-scale radiator so that good efficiencies to be arranged.
Module can include the control circuit of for example adjusting level or data channel.
Processor can have data inputs to receive voice data/program.
