Abstract
The utility model discloses a U-iron for a loudspeaker, comprising a body (1) with a concave space, and at least one groove (2) is arranged on the concave wall of the body (1). The groove (2) extends to the bottom of the concave space from an opening end along the axial direction of the body (1). After the structure is adopted, the inner wall area of the concave space of the U-iron is increased, and the radiating area of the U-iron is also increased so as to guarantee the tone quality of the loudspeaker and avoid noise.
Description
Technical field
The utility model relates to a kind of acoustical generator accessory, specifically is a kind of loud speaker U iron.
Background technology
General acoustical generator as loud speaker, buzzer, microphone etc., mainly is the combination that utilizes magnetite, vibrating diaphragm and voice coil loudspeaker voice coil, but produces suitable resistance via the resistance of modulation, so that electric current produces sound by the back.At present, known loud speaker is made up of magnetic circuit system, vibrational system and support system.And usually, the magnetic circuit of loud speaker part mainly is made of magnet and clamping plate, the magnetic conductor of the column that magnet generally comprises base, link to each other with base.According to concrete operating position, magnet is divided into T iron and U iron usually.Wherein, U iron generally has the interior concave space that can place magnetite, during use magnetite and voice coil loudspeaker voice coil are placed in the interior concave space of U iron, then with the U ferropexy on the basin frame.
But loud speaker in the course of the work, because the effect U iron of electric current and coil can generate heat, thereby the sound tonequality that causes loud speaker to send is bad, also can produce noise.
The utility model content
Technical problem to be solved in the utility model is that a kind of loud speaker U iron that guarantees the tonequality of loud speaker and avoid noise is provided.
For solving the problems of the technologies described above, the loud speaker that the utility model provides U iron comprises the body with interior concave space, and the inner concave wall of described body is provided with at least one groove.
After adopting above structure, the utility model compared with prior art has following advantage: owing to be provided with groove on the inner concave wall of U iron, increased the inner wall area of concave space in the U iron, promptly increase the area of dissipation of U iron, thereby guaranteed the tonequality of loud speaker, also avoided noise.
As improvement, described groove is along the bottom that axially extends to interior concave space from openend of body.After adopting this structure, make the area of dissipation of inner concave wall bigger.
As further improvement, the interior concave space bottom of described body has boss.After adopting this structure, saved in flat interior concave space the magnetite pad has been set, saved cost, simplified structure more.
Description of drawings
Shown in Figure 1 is the sectional structure schematic diagram of the utility model loud speaker with U iron;
Shown in Figure 2 is the elevational schematic view of Fig. 1.
Wherein, 1, body; 2, groove; 3, boss.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By Fig. 1, the utility model loud speaker shown in Figure 2 as can be known with the structural representation of U iron, it comprises the body 1 with interior concave space, the inner concave wall of described body 1 is provided with at least one groove 2, and described groove 2 is along the bottom that axially extends to interior concave space from openend of body 1.The interior concave space bottom of described body 1 has boss 3.
Claims (3)
1. a loud speaker U iron comprises the body (1) with interior concave space, and it is characterized in that: the inner concave wall of described body (1) is provided with at least one groove (2).
2. loud speaker U iron according to claim 1 is characterized in that: described groove (2) is along the bottom that axially extends to interior concave space from openend of body (1).
3. loud speaker U iron according to claim 1 is characterized in that: the interior concave space bottom of described body (1) has boss (3).
