Abstract
The utility model discloses a multipurpose sound changing device. A loudspeaker, a main circuit board and a cell are designed in a flat container 1 whose right side is provided with an output hole of the loudspeaker, and the back side is adhered with one surface 4 of a hook (velvet) of a nylon hasp; an electret microphone is formed by that a package 3 at one surface of the velvet (hook) of the nylon hasp is connected with a mesh belt 2 and an electrical conducting wire 5 which are arranged between the flat container. The multipurpose sound changing device can be conveniently fixed on a telephone receiver, a mask and a microphone with the structure.
Description
The utility model is a kind of consumer electronics product, specifically, is multiduty speech that speech the transfers device (device of changing voice) of changing voice that carries out in voice grade.
At present, the device of changing voice of the speech on the market is mainly used in phone voice security aspect, and the code phone that telephone set factory produces is by having adopted the dedicated voice IC of modulating, peripheral circuit is simple, sound is resonant after adding power amplifier, and available potentiometer adjustment volume, thereby circuit is comparatively ripe.Because the relation of structure, purposes is restricted.
Task of the present utility model provides a kind of at confidential phone number, toy mask, the device of changing voice that many-sides such as Karaoke are used.
In order to solve above-mentioned task, the solution that the utility model adopts is: the device circuit of changing voice remains unchanged substantially, and improves from the structure of device.As a part, the microphone of speech input is as another part loud speaker and main circuit board and battery, and two parts are posted the one side of suede of velcro and the one side of hook respectively, and two parts connect with line and ribbon.Whole like this device just can twine with lead and ribbon, is fixed on other objects with velcro, reaches multiduty purpose.
By above-mentioned solution, whole device twines with lead and ribbon, is fixed on telephone receiver with the velcro form, mask on the objects such as Microphone for karaoke, thereby can both be used easily in many-side, and can take off easily, cost also increases seldom.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the dorsal view of the utility model embodiment.
Fig. 2 is the schematic diagram of Fig. 1 embodiment when the call voice security applications.
Fig. 3 is the schematic diagram of Fig. 1 embodiment when the mask of changing voice is used.
In embodiment dorsal view shown in Figure 1, many with the device of changing voice loud speaker and the main circuit board battery design in a flat container 1, the loud speaker output of container front, one side 4 Electret condenser microphones that the hook (suede) of velcro is posted at the back side are wrapped in by the one side 3 of the suede (hook) of velcro, ribbon 2 are arranged and make at interior electric conductor 5 with 1 of jerrycan to be connected.
Fig. 2 is that embodiment is wrapped on the telephone receiver 6 with ribbon, and its Electret condenser microphone 3 that is wrapped in the one side of velcro suede (hook) is fixed on the jerrycan 1 that is attached on the telephone microphone with the form of velcro.
Fig. 3 is that embodiment is fixed on the mask 7 of changing voice with velcro, and the appropriate section of mask is posted one side suede or hook of velcro.
Equally, it also can be fixed on other objects such as Microphone for karaoke easily.
