This system has a characteristic mass and stiffness, and a resonant frequency at which the system will vibrate freely. This frequency is known as the free-space resonance of the loudspeaker and is designated by F s. At this frequency, the voice coil is vibrating in the speaker's magnetic field with maximum peak-to-peak amplitude and velocity.
A child with the anxious-avoidant insecure attachment pattern will avoid or ignore the caregiver, showing little emotion when the caregiver departs or returns. The child will not explore very much regardless of who is there. Infants classified as anxious-avoidant (A) represented a puzzle in the early 1980s.
Anxious-resistant insecure attachment is also called ambivalent attachment. [11] In general, a child with an anxious-resistant attachment style will typically explore little (in the Strange Situation) and is often wary of strangers, even when the caregiver is present. When the caregiver departs, the child is often highly distressed.
Constant-voltage speaker systems are also commonly referred to as 25-, 70-, 70.7-, 100 or 210-volt speaker systems; distributed speaker systems; or high-impedance speaker systems. In Canada and the US, they are most commonly referred to as 70-volt speakers. In Europe, the 100 V system is the most widespread, with amplifier and speaker products ...
A dismissive-avoidant attachment style is demonstrated by those possessing a positive view of self and a negative view of others. [22] Adults with a dismissive style of avoidant attachment tend to agree with these statements: [23] I am comfortable without close emotional relationships. It is important to me to feel independent and self-sufficient.
All speaker drivers have a means of electrically inducing back-and-forth motion. Typically there is a tightly wound coil of insulated wire (known as a voice coil) attached to the neck of the driver's cone. In a ribbon speaker, the voice coil may be printed or bonded onto a sheet of very thin paper, aluminum, fiberglass or plastic.
The coding system used to interpret the attachment style expressed by the child has also been modified. Rather than focusing entirely on the expression of specific behaviors and emotions, the revised coding system assesses ways in which a variety of behaviors, such as talking, are organized to maintain and negotiate proximity and contact.
This corresponds to a balance between the attachment system which serves the function of protection and the exploration system which facilitates learning. [4] The function of other attachment styles can be explained in terms of an imbalance of intimacy and independence, a preoccupation with one of these goals.
