Abstract
The utility model discloses a loudspeaker, mainly composed of a loudspeaker main body, a magnetic pole core (3) arranged in the inner portion of the loudspeaker main body and a magnetic circuit unit on the magnetic pole core (3), and characterized in that a frequency divider set (9) connected to the magnetic circuit unit and a piezoelectric sounding piece (10) embedded between the magnetic unit and the frequency divider set (9) are also equipped outside the magnetic circuit unit. The loudspeaker is simple in structure, low in cost and perfect in sound quality, and can be widely used in various minisize home appliances, such as mobile phones, notebook computers and automobile sound devices.
Description
Technical field
The utility model relates to a kind of electronic technology field, specifically is meant a kind of loud speaker.
Background technology
At present, no matter be in various conference halls, theater or large-scale square, loud speaker is used widely; But because the operation principle of loud speaker is at present: at voice coil loudspeaker voice coil two ends incoming transport signal, voice coil loudspeaker voice coil is cutting magnetic line between magnet and magnetic conductive board, produces vibration, and voice coil loudspeaker voice coil promotes vibrating diaphragm and awl basin, sounds.A sound equipment will could be gone back the primary sound of original sound by high bass combination, and such device is the volume heaviness not only, and waste material.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, thereby a kind of simple in structure and portable loud speaker is provided.
The utility model is achieved through the following technical solutions: a kind of loud speaker, mainly by the loud speaker main body, the pole body of portion and the magnetic circuit unit that is positioned on the pole body of setting within it formed, and also be provided with the frequency divider group that is connected with magnetic circuit unit in this loud speaker body interior, and be embedded in the piezoelectricity sounding sheet between magnetic circuit unit and the frequency divider group.
Described magnetic circuit unit is by two magnetic conductive boards that are parallel to each other that are arranged on the pole body, and the permanent magnet that is entrenched between adjacent two magnetic conductive boards is formed; Described frequency divider group then is connected with the magnetic conductive board of innermost layer.
In order to ensure acoustical quality, the utility model also is respectively equipped with voice coil loudspeaker voice coil and vibrating diaphragm on outermost magnetic conductive board.
Further, described loud speaker main body is made up of support and the awl basin that is complementary with it, and described pole body then is arranged on the inside of this awl basin, also is provided with to be used to the dustproof screen covering that prevents that dust from entering on the awl basin.
Simultaneously, described frequency divider group is made up of more than one frequency divider.
In addition, also be provided with a piezoelectricity sounding sheet between magnetic circuit unit and magnetic conductive board, this piezoelectricity sounding sheet mainly is laminated by sheet metal and piezoelectric ceramic thin sheet.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is simple in structure, and is convenient and practical, can be widely used in the equipment such as earphone, notebook computer or automobile audio.
(2) the utility model is realized the effect of loud speaker by adopting piezoelectricity sounding sheet, and this piezoelectricity sounding sheet mainly is made up of sheet metal and piezoelectric ceramic thin sheet, so it is simple in structure, and is cheap and volume is little, is convenient for carrying.
(3) the utility model makes up and realizes that high bass cooperates fully, realizes perfect acoustical quality by increasing a frequency divider.
Description of drawings
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model overall structure schematic diagram.
Wherein, the parts name of Reference numeral correspondence is called among the figure:
The 1-magnetic conductive board, the 2-permanent magnet, the 3-pole body, the 4-voice coil loudspeaker voice coil, the 5-vibrating diaphragm, the 6-dust cover, 7-bores basin, 8-fixed support, 9-frequency divider group, 10-piezoelectricity sounding sheet.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment 1
Figure 1 shows that the structural representation of existing loud speaker, promptly this loud speaker with the awl basin 7 that this support 8 is complementary, is installed in the pole body 3 of awl basin 7 inside by support 8, and two magnetic conductive boards 1 that are fixed on the pole body 3 constitute.And between two magnetic conductive boards 1, also be embedded with permanent magnet 2, near pole body 3, then be provided with and bore voice coil loudspeaker voice coil 4 that basin 7 is connected with magnetic conductive board 1 and the vibrating diaphragm 5 that is complementary with voice coil loudspeaker voice coil 4, on awl basin 7, be provided with and be used to the dustproof screen covering 6 that prevents that dust from entering.
The structure of loud speaker of the present utility model as shown in Figure 2, and is the same with embodiment 1, and this loud speaker comprises the unidirectional connection of line, and controller is by the Transistor-Transistor Logic level signal controlling limit switch of transmission in the line; Gyrosensor support 8, the awl basin 7 that is arranged on these support 8 inside and is complementary, and the pole body 3 that is arranged on awl basin 7 inside with it.Loadspeaker structure of the present utility model also is provided with a frequency divider group 9 that is connected with the magnetic conduction unit at the place, base, inside of support 8, and is embedded in the piezoelectricity sounding sheet 10 between this magnetic conduction unit and the frequency divider group 9 with traditional loud speaker difference.
In order to ensure sounding effect, 10 of this piezoelectricity sounding sheets are laminated by sheet metal and piezoelectric ceramic thin sheet.Magnetic circuit unit is then by two magnetic conductive boards that are parallel to each other 1, and the permanent magnet 2 that is entrenched between adjacent two magnetic conductive boards 1 is formed.
In order to ensure result of use, these two magnetic conductive boards 1 are all perpendicular with the central axis of pole body 3.At this moment, just be formed with the magnetic conductive board and the outermost magnetic conductive board of innermost layer in the inside of support 8, what promptly be positioned at support 8 bottoms and close frequency divider group 9 is the innermost layer magnetic conductive board, and what be positioned at support 8 opening parts and close awl basin 7 is outermost magnetic conductor.
Described frequency divider group 9 is made up of more than one frequency divider, and these frequency dividers all are connected with the magnetic conductive board 1 of innermost layer by lead.
As mentioned above, just can realize the utility model preferably.
